Re: Stereo Question...
I don't really know of any sites that will help, but I don't hink you really need any. If you can install a speaker you should be able to install an amp.
Wherever you buy your amp just buy an amp wiring kit along with it. This kit should include a long positive wire to run from your battery to your amp, a short negative wire to use as a ground, a remote signal wire, a inline fuse holder to use on your positive wire, and possibly a set of shielded RCA cables. If you have installed an aftermarket head unit (CD player, radio, tape player, etc) in your dash there most likely is a set of RCA amp pre-outs on the back of the unit. Use RCA cables if possible because they will give you better sound quality and are easier to install. If you do not have RCA outputs on you unit make sure the amp you purchase has hi level inputs. Another thing that can help ease of install is a screw in battery terminal with an accessory hookup point on it if your terminals screw into your battery.
First find a place to install the amp and mount the amp securely. Make sure there is plenty of room around the amp to let the heat escape. Now run the negative wire from the amp to a good ground. Keep the ground wire as short as you can, and make sure you have a good ground, as this will effect the sound quality. Also disconnect the positive battery terminal.
Next install the remote signal wire. This is relatively simple if you have an aftermarket head unit. Most aftermarket units will have a remote signal wire on them to run either a power antenna or amp, simply connect the two wires. If you have a stock head unit find a switched power source that only comes on when the ignition is in the on position, and hook the remote signal wire to this. If you want you can install a rocker switch in the remote signal wire so you can turn the amp on and off and still listen to the radio. If you hook the remote signal wire to a non-switched 12 volt source the amp may not shut off and it will drain your battery.
Now install the sound wires. If you have a head unit with RCA jacks simply run RCA cables from the amp to the unit. Some RCA cables are directional so be sure to keep track because this will effect sound quality. The signal flows form the head unit to the amp. If you do not have RCA hookups simply hook up the amp as if it were a speaker with the left and right speaker wires going to their respective hi-level inputs on the amp. Be sure to keep track of the positive and negative wires, hooking them up backward will effect sound and possibly ruin your speakers.
