Now I am clueless about stuff like this and I admit it , So help me out here,
I recently bought a used Mopar Sound Deck at an auction to put in the back of my jeep (It has an 8" subwoofer and some tweeters and an integrated 50watt amp) The wiring harness came with it and I had no trouble hooking it up to the back of my radio, except for the red power lead, how exactly should I hook this up ,also It has a 5 amp fuse in the powerlead is 5 the right size I didnt know if maybe it had been replaced or what. Any help would be Greatly appreciated, Thanks!!

Do you know what guage that wire is? 5 amp seems small for a amp power lead. Mine is a 10 guage (pretty thick) and has a 30 amp fuse and I've seen 40 reccomended.

You can pretty easily run it through the firewall and connect to the battery.

The wire is not so big , I'm guessing its something like 16 or 18 gauge there is a set of wires (i have a 98 tj) close to the fuse box there are two wires a blue one and a red one the red one says unswitched Aux power 10 amp max. and the blue one says switched aux power 3 amp max. could I use these??

The blue one you could use to turn on the amp. All it would do is act like a switch to turn on or off. It won't provide the power to the amp to run it. Do you have a place or a wire on the amp that says switched? If so use the blue you found.

For the power for the amp....I'm not sure if you can use that other one or not. Like I said before, I would assume that an amp would have a larger wire with a higher fuse BUT I COULD BE WRONG. I would see if you could find a service manual on that amp online. Shouldn't be too hard to find if it's name brand. Or just replace it with about a 10 guage wire and run it straight to the battery if you have that blue switched wire hooked up also.

Just so you know, I'm no expert when it comes to these things. I just installed an amp in mine over the weekend and that's what I'm basing my experience on.

that just sounds kinda funky. there's not much to wiring an amp. constant power wire(i like 8ga with a 30/40A fuse), a switched power wire(usually 16ga or so used just to turn the amp on and off), a ground wire(again, i like 8ga...and make this one short), and the wires for the music. it sounds like you got the last one done. i'd just run the others like a normal amp. the constant power goes to the battery with the inline fuse. the switched power goes to the remote wire or power ant wire on the back of the headunit. and ground is self-explanatory.

just run the red power wire to the + side of your battery the bule will have to go to your fuse box if you have a factory radio you can run it to your ign. fuse to give you power when you turn the key forward. you should be fine with that size power wire. you are just running a 50 watt amp. you would need a bigger wire if you were pushing more watts

Thanks All , I think I've got it. thanks again
