I know almost nothing about car audio, but here it goes...I plan on running an Xtant6.1 amp and an 12" infinity kappa perfect VQ sub in a .85 cubic foot box. The amp has a certificate that says its rated at 600 watts total power, is this too much for this sub? All of this will be running off of a stock bose headunint in my Audi. Thanks guys.
if you really want something good for that amp look into Ascendant audio(atlas) get two of them run them in parellell to a 2ohm load and they will SLAM!
