I believe he wants new so all of though are out of the question, plus hed would need alot of eletrical for that. Dont all thoughs amps take 2 runs of power/ground?
And from what ive been told,(ive been asking everyone who OWNS AQ stuff what they think, many of the peeople also ran sundown, DC, fosgate) AQ amps will keep up with the best of them. A member told me he had the AQ1200 and an SAZ1200, it he had to buy again he would go AQ. Since he didnt believe the quality was worth the price jump.
All in all ide go with one of these options if your trying to stay new
AQ3500
Sundown SAZ2500
Lanzar Opti4000D
If your ok with used stuff ure options are almost limitless, but i like my amps new lol Dont want someone elses mistake in my truck
