I have my power wire ran from my battery to my amp with a 30 amp inline fuse, i have my wire grounded but i used a double ground, since i have to have two grounds for my amp and cap i went from using a single wire from my spare tire and doubled up my wireing to i have 2 ends, one going to my amp and one to my cap, so pretty much 1 wire splits into 2. well my main question is what else do i need? i know i need to go to radioshack tomorrow to get speaker wire but do they carry direct wire, or on/off wire as some call it? its the wire that when i turn my car off my headunit tells my amp and capacitor to shut off aswell. or could i use speaker wire on this aswell?

You will need to run a "remote" wire that tells the amp when to turn on and off. Nearly all aftermarket head units have a blue remote wire specifically for this purpose. Speaker wire would work but as long as you're there you might as well pick one up.

You didn't mention whether you have RCA cables. You'll need those too unless you plan to use the high level inputs on your amp(if it has them).

i have RCAs ran aswell, radioshack is closed so i might run to kmart for the speaker wire, i cant find the remote wire on anyones website and i dont know what its called in the stores, my buddy is the one for gave me the idea on the speak wire so i think i might run with that aswell.

and yes my headunit has the blue wire at the back.

I bought a few bulk spools a couple of years back. It's handy for things like remote wires. It's also nice to have so I can extend harnesses etc and keep close to the same color.

careful - aftermarket decks can have 2 blue wires. one is for a power antenna, the other's remote wire. you'll find out real quick if you use the wrong one (amp will turn off when you put in a cd and turn it back on when the radio's on)

remote wire is just an 18gauge wire

oh and autozone sells bulk wire

my wires were marked (thanks sony), and i just used speaker wire as my remote wire, i got the system hooked up and it pounds hard...i think, i need to hide the wires but for now its working
