Ok, thanks, so as long as it is tuned properly then it wont blow up the speakers. Me and my friend are going to get together one day and tune our systems with an oscilloscope.

You might know the answer to this question as well. The amp is 18.5"s long so near about 45-50cm, so I wont be able to hide it under the seat meaning it will probably have to go in the boot. Is it ok to run the wire from the front battery all the way to the back, then run the speaker wire from the amp back to the front through the doors into the speakers? Or will this cause too much voltage drop from the amp to the speakers? The speakers are mid range so id prefer to give them the best power I can. I would use 12ga speaker wire, then probbaly 2ag wire from the battery to the distribution block running 4ga to each amp. I would guess there is 4 meters of 2ga, less then a meter of 4ga, then 4 meters of 12ga back to the speakers.
