I have a question about my AQ1200. I got everything wired, and the system is working, but it is not being powered all the way. It's like the resistance is wrong or something. Everything should be wired to be at 1ohm. Ive tried wiring the two pos and neg different ways, but it still plays the same way. Do I have to have both positive and negative terminals going to my subs?
No it doesn't matter if you use one set of terminals or two.
Check resistance across the speakers with a DMM to be sure they're wired right. How did you set the gain? Try plugging an mp3 player into the amps inputs (need a headphone to RCA cable for that) and play with the gain, see it it's good, if so problem is with the HU.
