Frequently asked questions

The power input should be connected directly to the positive terminal of the battery. For safety, install an in-line fuse holder (not included) as close to the battery positive (+) terminal as possible with an ampere rating not to exceed the total value of fuses in amps. The PS2-150 requires a 10A fuse and the PS4-300 requires a 15A fuse.

The RCA inputs provide for increased bandwidth and allow you to still utilize the speaker outputs for driving smaller front speakers directly. The distortion level is considerably lower from pre-amp (low level) outputs than speaker (high level) outputs.

The input sensitivity control adjusts the signal level from your car stereo/source to match the amplifier's sensitivity. It is not a volume control. To adjust, set the input level control at mid-point, listen for audible distortion as you increase the car stereo volume control, and then turn the adjustment level control toward max in stages until the onset of audible distortion is heard, then decrease to min level prior to the immediate point of audible distortion. If distortion is immediately heard, turn the control to min until the sound is clear.
