QuestionQUESTION: can I connect a 2 channel sony xplod 1252 gtr amp to a kicker 07dcvr 12 enclosure with only two connection posts? or do I need to get a mono amp?
ANSWER: Hi Cal,
To answer this, I'd need to know how many DVCR12 subwoofers are in the enclosure, and what's the final impedance of the sub system. If it's a 4-ohm package, then you can connect the Sony amplifier to the subs in "bridged" mode. If it's rated at 2 ohms, however, you'd probably be better off with a mono amp.
If you can follow up with more information about the subwoofer system, I can try to give you a more detailed answer.
Thanks

QUESTION: Thanks Brian- sorry for the lack of info... there are 2 subs in the box at 2 ohms, so I think I'll need a mono amp. Class D or BD?
AnswerCal,
Yes, a mono amp is the right way to power that subwoofer system. You should get good results with any amplifier rated between 400 to 800 watts RMS at 2 ohms. Because it's a ported enclosure, however, I'd suggest looking for an amplifier with a built-in subsonic filter. This helps prevent damage to the subwoofers from playing bass frequencies below the box's port frequency. When you're using a ported box, playing very deep bass tones can cause distortion and damage from "over-excursion", which basically means the subwoofer cone can be forced past its mechanical limitations. A subsonic filter removes these very low bass frequencies from the audio signal.
There are many amplifiers available that will work well for you. One amplifier that would be close to a perfect match is Kicker's ZX750.1. It produces 750 watts RMS into a 2-ohm load, and includes a built-in subsonic filter.
Hope this helps!
Brian
