Amplifier location
Important! Allow air circulation around the amplifier.
The DLS Performance series of amplifiers have a compact design that allows great flexibility in mounting. You can mount it under a seat or in the trunk.
When you select a location, do remember that the amplifier generates a lot of heat. Choose a location where air can circulate freely around the amplifier. Do not cover the amplifier with carpets or hide behind trim panels. Do not mount the amplifier in an inverted or upside-down position.
Check all locations and placements carefully before making any cuts, drilling any holes or making any connections.
Disconnect battery
Before you start the process of installing an amplifier, disconnect and secure the negative terminal from your battery/power source. This will prevent the risk of damaging yourself or the products. Place the disconnected terminal in a secure and isolated location away from any possible connection belonging to the battery/power source system.

PROFFESIONAL TIP If amplifier installation kits are available with different sizes of power cable, chose the heaviest power cable to improve sound quality and to allow more amplifiers to be installed now or later.
The oversized power terminals on PS1.500 and PS4.110 accept up to 4 AWG / 20mm cables. Depending on length we recommend using 4 AWG / 20mm to PS1.500 and at least 8 AWG/10mm to PS4.110 for best performance*. Both the positive wire and the ground wire must have the same size. */OFC copper
NOTE! To avoid cable fire, be sure not to oversize the main fuse value for the power wires.
THE DC-FEED Maximum main fuse values for different cable sizes: 6 mm / 10 AWG: 25 A 10 mm / 8 AWG: 40 A 16 mm / 6 AWG: 60 A 20 mm / 4 AWG: 100 A 35 mm / 2 AWG: 150 A 50 mm / 1 AWG: 200 A
Tools and materials
TOOLS – Insex, Flat and Phillips screwdrivers or bits. – Wire cutter. – Wire stripper. – Electric drill with drill bits. – Crimping tool. – Digital multimeter or test lamp. – Wire brush, scraper or a piece of an abrasive
sheet to remove paint for a good ground connection. – Grease to protect the ground connection from oxidation.

– Sheet metal screws for mounting the amplifier to the amplifier board and the amplifier board to the car plus some extra for fuse holder, amplifier ground etc.
– Electrical insulation tape.
– ½ inch thick plywood or particle board for the amplifier to be mounted upon.
AMPLIFIER INSTALLATION KIT If available, buy an amplifier installation kit. It contains normally all you need. This is what you have to buy, if you buy the items separately:
– 20-25 feet = 6-7,5 meter power cable, minimum AWG 8 = 10 mm or heavier.
– 1 pc of fuse holder with fuse to install close to the car battery (see below).
– 20 feet of AWG 15 = 1,5 mm wire for remote turn on / off cable from radio.
– RCA-cable for input from radio. ~ 20 feet or 5 meter for trunk installations ~ 12 feet or 2-3 meter for under seat installations
– Two ring crimp terminals, one for connection to the battery plus and one for the amplifier ground connection.
– Four to eight splicers to connect speaker cables to high level input cable, if high level input is used.
– Wire ties.
– Insulating grommet or insulating tube.
FUSES Fuses are installed inside the Performance PS amplifiers.
Recommended fuse rating:
PS1.500:
50A
PS4.110:
40A
NOTE! Max fuse value is always related to cable size & quality.
Power wiring
POWER TERMINAL (+12V) Connect the fuse holder as close to the vehicle battery+ as possible, using 4 AWG /20mm or 8 AWG/10mm power cable. Use a ring crimp terminal to connect to battery. The 4 AWG/20mm cable can use a 100 Amp fuse , if the cable is smaller, the fuse value must be lower (see table on previous page). This fuse is to protect from cable fire!
DLS fuse holder

Battery + pole
Be sure to use a rubber grommet or a plastic insulating tube where the cable passes the firewall or other places where it can be easily jammed. Use wire ties to secure to existing cables in the engine compartment.
GROUND TERMINAL (GND) Connect to a good chassis ground. The ground connection should be clean, unpainted metal to provide a good electrical connection. Use a wire brush, a scraper or a piece of an abrasive sheet to clean the metal. Use a lock washer or two to secure contact. Protect with silicon grease or by paint applied afterwards.
POWER LIGHT / PROTECT LIGHT The power indicator (blue) is lit when the amplifier is turned on.
The protect indicator (red) is lit when the amplifier shuts down from over-heating, or a short circuit (speaker failure). Turn off your audio system to reset the amplifier if the red protect light is turned on. If the red lamp doesn’t turn off, contact your local dealer for advice.

REMOTE TERMINAL (REM) For RCA cable signal input: Connect the radio power antenna lead = remote turn on/off from the car stereo to the amplifier remote connection. This turns on the amplifier whenever the car stereo is turned on. You can either use the built in remote cable in the RCA cable itself or use a separate cable.
Sometimes a small disturbance may enter the amplifier coming from the remote voltage , through the built in remote wire and into the RCA cable. Thus we recommend to use a separate remote wire and run the RCA lead separate from remote wire, power cables and speaker cables.
If there is no remote voltage available from the stereo, you must connect to the ignition key through the radio or any accessories fuse. When high level input is used the amplifier starts automatically when your car stereo is switched on.
To head unit Power Antenna lead or remote output.
A cable up to AWG 14 (2,5mm ) fits the amplifier remote (REM) terminal.
HIGH LEVEL INPUT WIRING Most headunits are pre-installed from the car factory and have no RCA output, in this case you can take the signal from the speaker output instead. Use either a separate remote cable or let the high level signal automatically start the amplifier.
Connect left and right speaker wires coming from the car stereo to the high level input as shown. You must connect both plus and minus as the inputs are balanced, connecting plus only gives lower level and bad sound quality. By changing the polarity of plus and minus, you can change the phase.
The High level connector wires match with DIN wiring color codes. The car loom wiring may have different color codes. When High level inputs are used, the turn on signal for the amplifier is taken from the high level input, therefore no separate remote wire is needed.
PS1.500 Connected high level left and right are summed on the inside.

Audio wiring
LOW LEVEL INPUT WIRING Inputs may be low level from the RCA output of the car stereo or high level from the car stereo speaker output. Low level = RCA is prefered for the best sound quality.
Important! Use either the low level or high level input, do not use both at the same time.
Use a pair of shielded stereo audio cables with RCA type jack. Most trunk-mounted amplifiers need a 20 feet RCA cable (approximately 5 6 meters).
Connect to input socket CH1 / CH2 on PS1.500.
PS4.110 has dual inputs CH1 / CH2 and CH3 / CH4 depending on your chosen configuration you can use either two separate RCA cables, or a single RCA cable and set the INPUT MODE switch to 4CH or 2CH.

Input level control – GAIN
The GAIN control, MIN MAX, matches the output of your radio to the input of the amplifier. After installation is complete, make sure the input of the amplifier is turned down all the way to MIN. After turning the head unit ON, you can adjust the GAIN level, A normal setting is from 12 – 14 o’ clock.
High Pass Filter – HPF
Low Pass Filter – LPF
PS1.500 The low pass filter is mostly used for subwoofers. It will allow low frequencies only and blocks higher frequencies. For a subwoofer a typical setting is 60 80 Hz.
Bass EQ or Bass boost is used to increase the bass volume at a specific frequency (45Hz). You can adjust the amplification from 0dB (no amplification) to +12dB. This function is used to compensate for the bass box function and to adjust for your own taste of bass. Set level control at 0 dB if you want it to be inoperative.
PS4.110 The high pass filter blocks low frequencies from reaching the speakers, mostly used to protect small speakers from deep bass.
Set the 1/2CH X-OVER and the 3/4CH X-OVER switches to HP to activate the filter, set the switch in the middle position F if you want to run the amplifier in full range mode without limiting the frequency range.
Low Pass Filter – LPF
Subsonic filter
PS1.500 The subsonic filter is adjustable between 10Hz50Hz and reduces the lowest frequencies below 50 Hz. If small woofers are used use a higher frequency setting for the subsonic filter. Choose the frequency that best suits your ears and the installation.
Subsonic filters are recommended with Vented / Ported enclosures to prevent subwoofer damage from exceeding X-Max at frequencies below the box tuning frequency.
PS4.110 The low pass filter is mostly used for subwoofers. It will allow low frequencies only and blocks higher frequencies. For a subwoofer a typical setting is 60 80 Hz. For midbass a typical setting is 200-300Hz.
Set the 1/2CH X-OVER and the 3/4CH X-OVER switches to LP/BP to activate the filter, set the switch in the middle position F if you want to run the amplifier in full range mode without limiting the frequency range.
BP means Bandpass filter and it activates the HP filter as well. To limit the lowest frequencies from the connected speaker.

Testing
RECONNECT BATTERY When wiring is complete, reconnect the battery negative terminal.
TEST POWER WIRING 1. Turn on the head unit but do not turn up the
volume. The amplifier power light should come on. If not, check the remote and +12 volt wires. Also check the ground connection.
2. Turn up the head units volume slightly. All speakers should operate. if not, check wiring connections at amplifier and speakers.
TEST SPEAKER CONNECTIONS Make sure the speakers are connected right. Use the balance control on the head unit to make sure right channel is on right speaker etc. If speakers don´t play at all, one or both speaker wires may be disconnected.
Troubleshooting
If problems occour during the installation, or later, this guide might help you to find out what´s wrong.
THE AMPLIFIER IS DEAD 1. Check power lead, ground and remote connec-
tions at the amplifier using a multi meter. 2. Check the battery terminal connections. 3. Check the power lead fuse or circuit breaker. If
fuse damage continues, inspect the power lead for short circuits. 4. Check the amplifier protection fuses. Are these broken change to new ones with the same value. If short circuiting continues, contact your local DLS dealer. A fault may be in the amplifier. 5. To start the amplifier requires a remote voltage of 9-15 volt. Check the voltage with a multi meter.
AMPLIFIER PROTECTION FUSE BLOWS AT LOW VOLUME 1. One or more speaker cables are shorted. Make
an insulation test with a multi meter. The cables must not have a connection to earth.
AMPLIFIER PROTECTION FUSE BLOWS AT
LOW VOLUME The amplifier is overheating due to inadequate ventilation. Check mounting position is clear: 1. Move the amplifier to a location with better venti-
lation. 2. Install one or two fans to cool down the heat-sink. 3. Overheating can also be caused by impedance
load below the level permitted.
NO OUTPUT FROM ONE OR MORE SPEAKERS 1. Check balance control position 2. Check fader control position. 3. Check all speaker cable connections. 4. Check signal lead plugs and cables. 5. Change left and right signal lead plugs in the
amplifier to see if the problem moves to a different speaker, the lead has a fault. If the problem remains, the speaker or amplifier is at fault.

Proffessional tips
Noise problems
WHINING NOISE VARYING WITH ENGINE REVOLUTIONS Do this: 1. Rewire the power supply (12 V) to source unit
direct from battery. 2. Rewire ground wire from source unit to clean
position on chassis. 3. Check all power connections to ensure that
they are clean and tight. 4. Check quality of system ground connection. 5. Install a power capacitor with connections as
close as possible to the alternator. This bypasses the noise at source and eliminates many issues with noise problems. In cars with a jump start connection, this provides a conventent connection point for the capacitor.
CONSTANT WHINING NOISE Do this: 1. Ensure that all equipment has a common
ground point. 2.Check quality of earth strap connection from
battery negative terminal to chassis. 3.Disconnect signal cables from amplifier to see if
noise disappears. If so the leads are picking up noise. Test this by laying a new cable over the seats and reconnecting to the amplifier. If the noise does not return, reroute original cable away from source of interference. If noise remains regardless of cable position, try to use so called Quasi-balanced signal cables. DLS PRO-cables are Quasi-balanced.
Installation in trunk
When installing the amplifier in the trunk, run the power wires along the same path as the other vehicle wiring. Many cars have insulated channels for wiring. You will have to remove the door sill trim and the carpet.
Speaker polarity check
All speakers in a car audio system should be connected in phase (the same polarity). All speaker cones must move in the same direction. Out of phase speakers will cause a lack of bass, and a poor stereo soundstage.
Checking polarity: Hold the – connection of the speaker wire to the terminal of a 1,5 Volt flashlight battery. Tap the + wire on to the + terminal of the battery, and observe the movement of the cone. The cone should move outwards when the wire touches the battery, and inwards when the battery is removed. If it is the other way around, the speaker has been connected backwards and it must be removed and connected correctly.
If your system also has a subwoofer connected through a passive 6 or 12 dB crossover, try to connect this with various polarity and judge what sounds best. The phase shift in passive crossovers sometimes makes it necessary to change polarity.

NOTE! Tweeters can not be tested this way, double check the connections instead.
Securing wires
Use wire ties to bundle together when possible. (But never bundle speaker wires or signal cables together with power wires).
Crimp connections
Purchase crimp connectors and crimping tool. Connectors are color coded. 1. Strip 1/4 inch (6mm) of insulation from the wire 2. Insert into connector 3. Crimp tightly
