from what i've heard, u want ur amp to have atleast have the power of your amp...but i dont know about that stuff..

mono amps give you big bass. they do not have a high pass/low pass switch, so the vioces will come through your subs(which sounds like crap). 4 channels are capable of running up to 4 speakers(mostly used for componates such as door speakers and deck speakers). I think a 2 channel is what you are looking for. Depending on the brand you go with, most amps are under rated. Cheap brands will over rate where as good brands will under rate. Ex: I had a Rockford 360A2 amp that was capable of pushing nearly 600 watts; i also had a power acustic 520 amp but i think it only pushes about 400...maybe less. If you want to stick with rockford, i would get something around 500 watts. a good rule of thumb for price is about $1 per watt.....unless you buy off ebay

What kind of box are you using?

thanks for the help guys! I am going with a bandpass box. The amp i am currently looking at is the audiobahn a8002t amp which has 800 rms watts and it has two channels. That seems like a good choice.

yeah, that should be fine. does the box have one terminal or two? if it has 2 and you desire more bass, you can run the subs bridged by putting the speaker wires together (+ ith +, - with -)then hook them to the amp with right + and left - (sometimes right - and left+, depends on the amp though it should say on the amp. you will notice a conciderable differance. Enjoy!
