Amazing performance for a 6.5" speaker

The following review is for HIPPOXL64, which is a part of the bundle you are viewing.

I just had two of these installed in my 2009 chevrolet crew cab pickup yesterday and I am pushing everything with a Sundown Audio 1100.5 amp which puts 800 watts to these two speakers. I cannot believe what these sound like. The guys at the shop that installed it were in disbelief as well. Its amazing what the can do.

Great quality

The following review is for HIPPOXL64, which is a part of the bundle you are viewing.

Highly recommend these subs. I got a custom box made for mine and it pounds. The only thing I might consider changing would be the direct leads.
