Great Amp. It bangs!

The following review is for SIA-5000D, which is a part of the bundle you are viewing.

This amp pushes my 2 sundown audio u series to the max. Hits the deep bass like nothing. Bass knob is nice for adjustments depending on genre/song. As always Sonic Electronix always has excellent customer service and is fast with shipping!
