I want to know if I should bother amping all my speakers (coaxials in the doors, 6x9s in the rear shelf) in order to really boost the sound level, or whether just doing the 6x9s will improve the sound enough.
Also Ive been thinking about getting a sub and amp. If I end up with two amps do you have to run two separate power cables back to the battery or can you use just one to power both amps.
