ULTIMATE A-series
Congratulations, you have just purchased the finest mobile audio amplifier that today´s technology can offer. DLS offers a series of high quality car audio products for real music lovers, and we are sure that you will enjoy a high class car sound for many years.
CAUTION!
Some of our amplifiers are capable of producing a sound pressure level that can cause permanent damage to your hearing system. High sound pressure levels combined with long time listening can give permanent damage to your hearing system. Choose a listening level that is comfortable for your ears.
To establish a safe level:
Start your volume control at a low setting. Slowly increase the volume until you can hear the music comfortly and clearly, without any distortion. Sudden sound shocks are dangerous.
The following noises can be dangerous with constant exposure:
90 dB | Subway, motorcycle, lawn mover | 4 hours max |
100 dB | Chain saw | 2 hours max |
120 dB | Rock band live concert | 30 minutes max |
140 dB | Gunshot blast, jet plane | 0 minutes |
Installation
Before you begin to install | Disconnect Battery |
Before you begin you need to read the manual, to have some tools, cables and other material available. There is one such list of material on the following page.
Amplifier location
Important
Allow air circulation around the amplifier.
The DLS ULTIMATE amplifiers have a great flexibility in mounting but the best is to mount it somewhere 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 upside down under the hat rack.
In the amplifier case there are four mounting holes. If the surface where you intend to mount the amplifier isn´t big enough you can mount it on a separate fibre board or similar. This will also isolate the amplifier chassies from ground.
WARNING!
Check all locations and placements carefully before making any cuts, drilling any holes or making any connections.
Before starting the instal- lation, always disconnect the negative terminal of the battery.
Professional Tip:
If amplifier installation kits are available with different size of power cable, chose the most heavy power cable to improve sound quality and to allow more amplifiers to be installed now or later.
These are the minimum sizes of power cables we
recommend for the different models: |
| ||
Cable length:< 1,5 m | 1,5 - 4 m | >4 m | |
A1/A2 | 10 mm2 | 16 mm2 | 21 mm2 |
A3 / A4 / A5 16 mm2 | 21 mm2 | 33 mm2 | |
A6 | 21 mm2 | 33 mm2 | 50 mm2 |
A7 | 16 mm2 | 21 mm2 | 33 mm2 |
A8 | 10 mm2 | 16 mm2 | 21 mm2 |
The ground cable must have the same size.
Max fuse values for different cable sizes:
6 mm2 (9 AWG) :25 A | 10 mm2 (7AWG) :40 A |
16 mm2 (5AWG) :60 A | 21 mm2 (4AWG) :100 A |
