I have an Alpine ida-x100 headunit with the recommended harness. All other audio equipment is stock. I read that the rear speakers only work at certain frequencys... Why would that be? I messed with my bass freq to get a rise, but nothing. Also read that it may be that the remote wire needs to turn on both the front and rear... But aren't they from the same amp..?
What are our speaker sizes? I read 6 1/4, but looks more like 5x7 by the grill.
