Replacing Ground Wire

SOURCE: Rockford Fosgate p 325.1 amplifier problem

i have the same amp basicly i think its your battery getting low and not as great of a charge i had to go and buy a 50 dollar capictor works great now

SOURCE: when my bass hits, my car lights flicker.

Is the problem much more noticeable when the car is at idle? Double check that Alternator output. 70 amps is not high output, and if the problem is especially noticeable at idle, it's probably due to the alternator putting out lower voltage( a common thing with alternators). Also, with that much draw from your sub amp, the wire from battery to alternator should be beefed up, as well as the ground wire from battery. You can make up your own cables by purchasing the wire to length and wire lugs at a local Welding shop, 4 gauge from alternator to battery is good. High output aftermarket Alternators shoot into the 200 amp range.

Hi my names Josh. I see you want put your rockford amp in. Assuming you have your factory radio you have some wiring to do. But first you need and amp kit it wil have the necessary wiring you will need in it to wire your amp to your car. You will also need a line level converter they you can pick on up at best buy other wise known as a pac converter. This will alow you to transfer the high level frenquency your radio puts out to a low level frenquency to go strait to your amp through a pair of RCA's thus giving you sound to your amp and then to the sub. Your wiring will consist of the ground which you will have to ground off the vehicles chasis no more than a foot from your amps designated location. Then you have you power 12v which is about a 4 gauge wire and will be fuzed and ran strait to the positive side of your battery and last will be your remote wire. Your amp will have a place marked remote on it that is strickly for you to wire to your radio/ignition source for powering the amp up when radio is on and powering it down when it is off. YOU MUST ISOLATE THAT WIRE with a 12 volt tester it will be the wire that is tied in to your radio to power only when your igniton is on and when you turn your key it should tell you if you know how to properly check for this wire. wants you istolate this wire you will want to tie into to it and then of coarse run it and tie it into your amps remote power again it will be marked remote on your amp. From there all you have left is tying in your line level convererter.. This takes some patience as you must make sure that you do isolate your sound left and right postive and negetive front and rear channels the line level converter will tie into either your front or rear channel but caution you dont get them mixed or you will not have a signal at all. Again my names Josh and i hope you are able to get it hooked up okay.
