Ebay, profile, hifonics, autotek, PPI.

Also to power the subs anywhere from 400-800 for the both will do fine. But we cant suggest an actual amp unless you can tell us whether you have DVC or SVC subs and whether there 2-ohm or 4-ohm. It should say on the basket of the sub.

And MA audio makes decent amp but they rate there power levels at 18volts last time i checked, your car will never go over 14.5v under normal operating conditions.
