Satisfied customer! AWESOME!

The following review is for CWRT124, which is a part of the bundle you are viewing.

Purchasing these 2 - 12” kicker CompRT subs was a good purchase to upgrade the sound for a my car. They have amazing sound! Wasn’t too sure if it would sound good with enclosed or ported box. I love the quality of kicker and the price was a great deal. Thank you Sonic Electronix! I will be purchasing more from this company.
