Amp wires are direct to battery..as far as sound, you need a line level converter to connect to your rear speaker wires (left/right) that sends the signal to the converter and switches it to RCA level outputs. You would then just connect an RCA cable from the converter to the amp and there you go. A converter is $20-$50 depending on the quality you want. The better ones connect to pos/neg and have a metal caseing.

Check the Remote Wire
It may not be sending a power signal from the car stereo. Without the remote wire working the amp will not power up

first you need to check your wires and sense you dont have a harness that is color coated to tell you what wires go where. You will need a 12v tester with a light on it to check and find your constant 12v wire on your factory harness going to the radio you will need to find your ignition and then your ground of course wants you have found those tape them off and isolate them from the other wires. Next you will need to isolate you front and rear channels both left then right for your sound and sense these are not labled you will need to check resistence of these wires which an ohm meter to tell you which wires are which you will have to have your radio on while doing this so you can fade your front and rear as well as your left and right doing it in sequence fade to your front left first hook up you ohm meter to check to see what your resistance is your ohm meter will read a negitive to the side you have faded thus it will give you your left and righ front and rear as you do this in sequence. As you find each pair of wires tape them and lable them front left and right rear left and right. This then will allow you to tap into those wires with a pac converter which converts the high input signal down to a low signal for your amp. By the way if it is a sub amp you are hooking up you will want to tap into the wires you tap of that go to your rear channel. after connecting those wires you will go out of the pac converter with a set of cables that will give you a sound sorce to the amp by the way for best qualitly sound i would run monster cables they are a little pricey but they are top grade when doing somthing like this. i wanted to make a note to you that on the pac converter it self you will have a small gain controll on it that you will want to adjust but not to high you can adjust it once you get the rest of the wires ran. back to the wires i told you isolate for your power one of those wires is going to be use in the process of running remote power to your amp which allows current to flow to the amp when the ignition is on this is also the same wire that alows for you radio to come on when the ignition is on. no when taping into that wire you will need to know somthing it is drawing directly from a fused source in your vehicle a very small fuse no doubt a small 10amp mini fuse, when you tap that wire and run from it you will need to put like a 20amp fuse its place to alow for adquqate power transfer bother to your radio and the amp with out blowing fuses all the time. i would suggest you locate that fuse before you ever get stared trying to do the wiring to the amp. once that is done all you have left is to run about 4 guage strait from your battery to amp again i want to stress that you want to fuse this wire as well with a heavier fuse it will be an inline fuse that you will be wiring in. If you get an amp kit it will have every thing you need to the job all accepting a volt meter. and or coarse last but not least you will need to find an adaquate ground source and also run about 4 gauge wire from your amp to a solid ground inside the vehile i find that the best place to ground is usually right off the the back of a lag bolt on the bottom of one of your seat mounts these mounts hold your sead down but are well grounded to the vehicles chasis. i hope that helps some my names josh if you have any questions you can call me 832 248 4144

Well when you blow a sub it can definantely short your output fets in the amp.

Rockford Fosgate... | Answered on Nov 02, 2009


With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.

If the voltage is OK, the amp will likely need to be repaired. If that's the case, do you want to repair it yourself? This amp may not be easy to repair. If you are not interested in learning to do this type of work, you should pay to have it repaired. If you want to repair it yourself, I'll try to help you through it.

most likely your remote wire or remote crapped out if not its your amp itself can you adjust and play without remote? if so go to this site for info and replacement as well as tips:

Hello, Quick question..is your amp turning off when the key is in the "off" position...If your amp is not turning off check your amp/remote wire.

Rockford Fosgate... | Answered on Nov 30, 2008


Did it only blow the fuse AFTER you applied remote voltage?

If you're going to try it again, do so with nothing larger than a 20 amp fuse.

try out the 4 gage because it was most likly pulling to much current through to thin of a wire and how long have you been running with that wire?

Rockford Fosgate... | Answered on Nov 08, 2008


what gage power wire are you running sounds like you need a smaller gage wire i have mine hooked up to a 4 gage wire and its working great

Rockford Fosgate... | Answered on Nov 08, 2008


It sounds like you are drawing to many amps and you need to go to a higher capacity altinator and a second battery would be a good idea as well. Start your car (do it at night makes it easier to tell) turn on your headlights without your stereo on look at head lights and see how bright they are then slowly turn stereo on and up if headlights dim you are drawing to many amps and need a higher capacity alt to charge and stop you from blowing them, and second battery with and isolator so you don't draw amps from the battery that starts your car.

This one is a real twister. Some questions of you might help to correct this problem.
1) Did you in some way hook the CB Radio up to the amplifier?
2) Did you use the same power lead from the amp to install the CB Radio?
3) In some way, did you unhook the ground from the amp?

These questions will help in solving your problem
I'll be waiting to hear from you
