I installed this into a custom fiberglass sub box in my G35. I wired it to push 1000 watts rms at 2ohm. The sound quality was decent, but not great. That may have been due to 1) fiberglass gives a different sound than wood boxes, and 2) the box it was in may have been too small. The box was approximately .9 sq. ft. which is in the stated tolerance, but I inverted the sub to give it some extra room, and added polyfill, which did improve the sound. Incredibly loud for a single ten in a sealed box, just didn't seem as accurate as it should have been. OCS has a great price on this sub, so if you're looking for something loud at an affordable price, this sub is worth the money, but I would try a larger sub box, closer to 1.25 sq.Ft.

These subs handle the bass and have a clean hard hit. I love them for the money. I have them hooked up to a PDX-1000 in my STI and in my boat too!!! Online car stereo is the best online car shopping on the net in my opinion. I recommend it to all of my car stereo friends!

Im thoroughly impressed with the quality of the subwoofer and would recommend to anyone looking for a great all around subwoofer. I have used 10w6 and 10w7 and can say this is a equal to even the greatest.
