6x9's hit harder
Crutchfield Customer Review (What's this?)
Ease of Use
Not a bad unit for the price, but my 6x9's in boxes (which are middle of the road but on an amp) hit harder than this. Not both of them together but just one will hit harder. It would add a little bass to a stock system but not much else. Your time (but probably not $) would be better spent with an 8" sub/box. Plus the wiring terminals are terrible, I used some needle nose pliers.
Pros: Price, packaging, does add bass
Cons: Doesn't add much bass, wiring terminals are tough to get at
