I have a 2002 chevy cavalier. I am installing a new sound system. At the moment I have almost everything but one amp and the head unit. I have a question regarding the head unit. How many pre-outs do I need? I am looking to run one amp for the speakers(one set of components, and one set of 6x9s), the one amp for my sub. Now my question is....Do I want three pre-outs or do I want to run everything off of a seperate crossover, the into the amps. If you get what I am asking. I think if I run everything off of a crossover, then I will only need one or two pre-outs(?). I am open to suggestions.

Depending on what kind of crossover you use. If you are going to use a crossover you would only need two preouts. If you are going to use a sub amp on your head unit I would make sure you have a sub amp output on there.

Don't let the smoke out of your equiptment..it doesn't go back in.
If you go with an active crossover, be sure to go with a high quality one, otherwise you'll have noise induced. An external crossover will usually give you a 3rd set of preouts, (for the sub) if your deck only has two. I prefer to go with 3 preouts on the headunit, and use the amps' built in crossovers for simplicity's sake. Another thing to look into is getting a 4 channel amp with line outs as well. This would allow you to connect your sub amp even though your deck may only have 2 sets of preouts.
I was looking into buying a profile clarus 4 channel amp. I had a profile for my onld subs and it did its job, plus it is very inexpensive. This amp is 65w x 4 RMS plus it has a set of pre-outs.
