im plannin to run my door speakers to a amp pretty soon, when i find the right deal. wondering on how do i do it? i have to run each speaker back to the amp? if so how would i go about doing this and not make it look sloppy. wires are visable . i was wondering if i just ran a line from the amp to the headunit and a power cable to the battery. but i dont think life is that simple. thanks for the replies. peace.
