If you are saying that you wired the remote to the RCA from the amp outputs then that won't work. A good way to make the amp just turn on is to have NO speakers attached, no input RCA's attached. Just have ground to ground and B+ to 12 (battery). If your then temporarily jump 12volt from the B+ terminal to the remote terminal then the amp should turn on and stay on as long as the jumper is in place. In a normal hookup, the remote 12volts is supplied from the radio (head unit).

I have a rockford fosgate punch 800 car amp and the problem i seem to be having is everytime i connect my remote wire to my stereo deck and i turn my stereo on it burns the fuse its only when i connect my...

Check the wires at the amp. Make sure that the wires are neatly bundled and clean cut when connecting them, a stray wire may be going under one of the connections from the battery input to the ground input of the amp, there for causing a direct short and blowing the fuse. I am assuming you mean that the amp's fuse is blowing. Get yourself a test light and test the wires for power. battery power?(12V) is always on and remote power(12V) comes on only when the radio is on(it should be the blue wire in color). Then make sure you have a very good ground, I always use the seat belt bolt or car seat bolt(direct to chassis). If you checked all these steps with no luck then the culprit may be your amp.

Need a wiring diagram for the gta4...please advise.

im not to familar with your amp but iv wired a lot of amps. You should just have your power ground remote and your sound. For your 12v+ You should not use anything less than about a 4 gauge wire fuzed and ran strait to your battery for this hook up your ground wire is to be no futher than a foot from your amp grounded to the vehicles chasis not over painted surface but a solid metal to metal contact with a good fitting for you connection on both ends. Then of coarse your remote which is labeld remote on your amp it is the only power source use to power your amp up and down it both completes the circuit and alows your amp to be manualy triggared with when you car reciever is on this remote wire is very important if you are doing the hook up your self you will want to make sure first that you if you have a factory radio in your vehicle to isolate that wire using a 12v tester. If you have an after market stereo in your vehicle such as a jvc kenwood alpine sony ect then you should have a blue wire with a white stip that is on the exsisting harness. That is your remote amp wire and it will tie in to your amps remote wire to power it up when the reciever is on or power it down when the reciever is off. My names Josh good luck with wiring the amp.

I need a fuse diagram for 2001 Nissan Pathfinder

Do you want to install a new unit or wht ? u may use this reference to work upon ....
Get yourself a digital multimeter. Find the +12V constant, 12V remote, and ground. Connect them to the new head unit. For speaker wire get yourself a 9V toy battery and listen to poping noise. If you have a factory amp you need to power up the factory amp. Use the wiring diagram below to serve as a guide. Test your wire first before connecting them.

P o w e r
Memory (+12v Constant) Red
Ignition (+12v Switched) (varies) Brown or Green
Ground (-) Black (varies - most don't have one)

S p e a k e r s
