Love em. Powered by a Rockford Fosgate amp @ 100w per channel. They are loud and sound really clear. I have my crossovers mounted in the trunk, but yes they all had to be wired. We ran new 16g soeaker wire throughout the entire car instead of using the factory cables.
You had the BA system right? When you installed, did you keep the factory HU, and just use the Sub Thump RCA harness? no issues with voltage into rca on amp?
