2005 Toyota Camry
Crutchfield Customer Review (What's this?)
The hicaps are well worth the money. I was hesitant to purchase these, I'm glad I did though. They made a massive difference in sound at over 50% volume. My K2's absolutely thump with lower frequencies now. If you are running speakers that handle lots of power or enjoy louder music the hicaps are worth it.
Pros: Night and day response over 50% volume. Speakers are loving the extra power from hicaps
Cons: Really wish these were just built into the amp originally.
