amplifier/subwoofer wiring?

A friend of mine just bought a completely new audio system, and he gave me
his old amplifier and old subwoofers which he wasnt completely sure still worked.

First off, all the wiring is rusted, broken or missing so my first question is where can i get the wiring to reconnect everything together.

second i want to test the AMP and subs before installing it completely, is there a way to do that?

You could go to your local best buys and get wiring kits, but more than likely they will b way over priced, find out what size amp and subs you have so you know what size wires to get. Its a little tricky to test them without running the wires to where you want to install

is there any possible way to connect the amp to another power supply so i don't have to hook it all up only to find out the amp is a dud?

I would imagine you could wire the amp up straight to your battery...or you could buy a power inverter but those aren't cheap.

Just run a wire from your battery to the amp. Ground it straight to the negative terminal. Now I'm not sure if you can do this part or not...if the remote turn on wire is a 12v wire then I think you can. Run the remote turn on wire to the + side of the battery. If I'm thinking correctly, that should at least tell you that your amp powers up.

For wiring kits...check out Amp Installation Kits, HDMI Cables

s3nt3nc3d is correct. Most all power amps have 12v remote lines so hooking both the positive terminal and the remote line to the positive post on your battery and the negative terminal to the negative post on your battery should turn the amp on.

A good way to test the amp (with the woofers) would be to use any type of coarse conductor wiring rated for electricity. I use a stiff 10 gauge stranded copper to power my 1200 watt amp with an 80 amp DC circuit breaker at the battery and i've never had any problems. I also use a stiff 12 gauge stranded copper to connect my amp speaker leads to my woofers. (I have 2 kicker 10s). Just make sure you don't use solid conductor wiring for power or speaker output as the dynamics of this type of wire aren't suited well for car audio.

It might be a bit of a waste of wire to cut short lengths for testing purposes, but if you have it laying around it works, so why not.

Be careful though because chances are if the wiring was rusted, the power amp may have came into contact with moisture / water at some point. Without a circuit breaker or fuse (assuming you're not going to use these while testing) be aware that the equipment has a possibly to short out and that might cause an electrical fire in the amp, or the power wiring (and at the very least you might get some nasty burns).

So if you're testing it with leads to the battery, make sure to use fuses in the hot side of the circuit that appropriate for the amp, or keep the leads where you can disconnect them quickly (touching them to the battery post should be enough to make the amp turn on).

To see if you have audio, you can easily find a mini-plug to stereo RCA adapter cord that will allow hook your ipod / MP3 player up to the amp to play a song as a test. Make sure that before you make any adjustments on the amp (gain or LPF) that you have it installed, working, and hooked to the head you're going to use as the levels of the audio coming from your test source will not be the same as those coming from the SW outputs on your head unit.

Hope this helps.
