I'm planning to customize my trunk. I'm going to a shop to do the box, but i want to buy amps and speakers somewhere else. What is a good 6x9 set of speakers for the rear. I need help in picking a amp too. I was thinking of getting a 4 channel amp to tower the two rear speakers and the sub, but I have 2 subs. what is the best possible thing i should do?

 

what are you trying to do with the car? spl or sq?

 

Forget about rear speakers altogether, spend the money on a good set of 2way or 3way components for the front, get a 2ch amp for them and get a mono block sub amp for the subs.

RMS wattage of amps will depend on continuous power handling, [RMS power] of the speakers and the subs. 94

PS, MM&Y of car it's going into and makes and models of any audio equipment you already have would help.
