How To Install Amplifier

1) Select a location for the amplifier that has good air circulation, such as in the trunk,or under a seat.

2) Use larger diameter RCA cables to connect the low-level output of the radio to the low-level input of the amplifier.

3) If the radio does not have a low-level output, you will need to use the high level, or speaker output. Generally, this is less desirable because of the noticeable increase in distortion and noise in such an arrangement. If your amp is for bass only, this may be a less significant problem.

4) Connect the power antenna lead from the back of the radio to the amplifier remote turn-on (REM) input. When the radio is switched on, 12 volts should appear on the lead, and start the amplifier when it is connected to the main power leads.

Make certain that the power antenna lead stays on while the receiver is on. On some radios, power may be switched off from the lead when a CD or tape is played, so the power antenna will come down. If this is the case with your radio, it may have a separate lead coming out for the amp turn-on function. Test the lead with a VOM, or test light. When the radio is on, in any function, 12 volts should be present at the amp turn on lead until the radio power is turned off.

5) Check the owner's manual for the recommended gauge (size) of the power and ground cables.

6) Connect the negative, or ground power cables before the RCA cables to prevent damage. If RCA cables are connected first, the amp may try to ground from these cables, possibly causing damage to other components in the system when it is activated.

Use a fuse on the line at the battery and amplifier. Check your owner's manual for the proper rating for the fuse. Fuse your amplifier(s) as close to the battery as possible. Current ratings (in amperes) usually doubles with each amplifier added to a single wire distribution circuit. For example, if you have one amplifier, using a 35 amp fuse, with two similar amplifiers, use a 70 amp fuse.

Ensure that power cables do not run next to RCA signal cables. If the cables are too close, engine noise, which may sound like a high-pitched whine, can get into the system. If whine is unavoidable, you may wish to use a Noise Filter. In addition to having your RCA cables mounted away from power cables, make them as short as possible, as signal strength is lost over distance, and higher frequencies are attenuated.
