If you realy want a other/new amp, in this budget. I would buy a used very nice sounding older mono in the range 500-1250 watts,
only up is like this amp, little bit big for your sub but nice number on the sheet, another nice one. All the amps there are named in this thread
before, are something out of the class not higher than!, amp 1,2,3,,etc. using same boards/comin from same chinese manufacture, typical
around middle and higher lowlines.
With a used hi- or high-end mono/2 channel, you would will have subbier fun with this sub.
You can´t beat the shit out of 500 w/RMS sub in a daily set up like a groundpounder. But you can have amp who can use colours, temperatur and control of sound,
and not these better cheap crap.
But if you have your AQ, ask a repairservice, i read something arround 100 $, not sure with shippingcost and new waranty.
Best offer you have, and if you are the AQ rid, another good option is the AQ 750 for 199, the AQ´s have much better resale-
prices than all the other "new" amps.
