It looks good, the fake wood overlay in the cabin, however, not my taste.

I competed on and off for several years and was an installer myself, I had 2x12 type R alpine's in my last XF on an old, hand built PPI (precision power) amp and I hit nearly 140, I am shocked you are not doing much more than low 130s.

What exactly has been done? Number of amps? Double spun or aftermarket alternator? Battery isolator with multiple gel cell deep marine batteries? single or double 0 gauge wiring? 0 gauge ground?

Many more questions, just wanting some info, looks like a nice setup!
