Preloaded 10" box hits very respectably. This amp provides enough power to reach the limits of the sub. Also, I've had no problems with heat, sound quality, etc. This combo puts out enough bass to drain my headlight beam sometimes. So a 1 farad capacitor is worth considering, though not necessary.
Excellent service, with incredibly fast shipping to Australia. I ordered a Pioneer CD deck and it arrived in 5 working days in perfect condition. The free extras for helping with installation are a welcome addition. Highly recommended to any other Aussies, or anyone else for that matter.
