This sub has so far exceeded expectations.

This combo exceeded my expectations for the money

This subwoofer is down right amazing, surpassed my expectations by far thank you Rockville, this one 12" in my extended cab truck is better than my buddy's two 10" s in his single cab truck

This worked very well and exceeded my expectations, added a lot of much needed bass to my tiny toyota yaris.

Everything works as it should all the wiring seems to be pretty good quality it was bigger than I expected and its just a hair off of sitting flush against the seats in my chevy sonic hatchbackI still have some adjustments to do but so far for the price you can't beat it is buy it again
