Help Wiring Components

I have the Audiobahn Component Set, ABC6003Q, 2 tweets, 2 woofers, 2 mids, and 2 crossovers. I was looking into getting a 4 channel amp (if I should get something else, please help), but right now, I have an extra A2601Q, a 2 channel amp, and was wondering if this amp could be used to power the speakers. Here is what I'm confused about: I have an alpine deck. It has 3 sets of preouts, one says front, one says rear, and one says subs. I currenly have the subs preout to my sub amp. Anyways, I've never used a 4 channel amp. Would the amp have 2 RCA inputs for the front and rear outputs? The current amp I have has only one input, so if this amp could work, which preout should I use? I know how to wire the crossovers to the amp, its the RCAs that are confusing me. Thanks for the help.

If the speakers are going to be in the front use the front RCA. If they are going to be in the read use the rear RCA Yes, a 4ch amp will have 2 RCA inputs, front and rear.

So, I could use my current amp, just use the front RCA outs? By the way, the tweets and mids are in kickpods, and the woofers are in the doors. Would using a 4 channel amp sound a whole lot better than using my 2channel amp with the front RCA out? Thanks.

you should get a four channel amp and run the comp biamped, you could run them all off the front rca channel, or if after trying this you prefer it, run the woofers off the rear channel and the mid/highs off the frnt, just make sure you keep the gains set right and know what the speakers can take. respect the volume knob. I don;t know that hwo channel amp, but I suspect you'd need more power

I am a little confused. Like I said, I've never used a 4 channel amp, so maybe I'm not picturing what kind of inputs a 4 channel would have compared to a 2 channel. What does "biamped" mean? And do you mean it is possible to run the woofers off the rear channel and and mid/highs off the front all with the same amp? I am confused because I only have seen amps with the left/right channels. The only way I see doing this is with two different amps. Is that what you mean by "biamped"? By the way, the amp is 150x2, and the components are 320 rms total. Thanks.

Any other suggessions?
