Usable

The following review is for BAK42BK, which is a part of the bundle you are viewing.

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

price is right

The following review is for BAK42BK, which is a part of the bundle you are viewing.

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

awesome products

The following review is for BAK42BK, which is a part of the bundle you are viewing.

I run 2 12inch audiobahn exursions on this amp and it pushes them very well. The size is perfect not to big and fits right unerneath the seat or small space. The best part is it stays pretty cool even after running most the day.
