Hey guys, I'm redoing my entire system and need your opinion on which subwoofer/amp to match to my HU/comps/amp.

I've decided on the Kenwood KDC-x696 HU, Image Dynamics CTX65CS components, and the Arc Audio FD2200 Amp for them.

My dilemma now is subs. I need a quality sub and amp set up around $450. I'm looking at around 400w rms, and 2 12"s. I'm thinking two Sundown Audio E-12D4s, and either the Nakamichi PA-1500 or Arc Audio 600.1.

Here are the links:

Thoughts? Opinions? Recommendations/alternatives?

Going for all around performance, leaning towards the SQ side, though SPL is of course important. Also, RELIABILITY is very important. This will be a pro install and I don't have time to tinker/fix etc.

Sealed enclosure btw. Thanks!
