AudioQue is no more is SQ... personally can't say i'd ever run AQ/SQ again, they have a sound to them i just don't like, with that said i do respect the HDC4 just for the money wouldn't ever run it. I like my Sundown, the SA-12s took everything i could throw at them. 4kw on a sub for 3 min (clipping) and still lived, the only weak spot I've found was when i had them in the NightShade box that has wayy to much port for SA's and ripped a surround.
Owned RF, Dual, Kicker, AQ/SQ, Sundown.
AQ is all about the SPL, the SQ sucks, I'd love L3's due to them being SQ and SPL and they can be abused if you wanted to put them through hell :3
I was on the right, clipped them to death that day, had to send them in for a recone.
