Ok, it's only been one month and I can't stop ordering from this fantastic store! Started off with something small (amp wiring kit) just to try it out, was impressed right away with the outstanding service and prompt delivery. These guys know their business and know how to treat their customers!

Custom built one inch for cabinets and using bpt60 tweeters grille covers fit perfect over this sub because of the way i put together the boxes these speakers will never need an amplifier to drive them.

It might only be a 8 inch subwoofer, but it can handle alot of power. The magnet is not to big so you can fit almost anywhere. Surprisingly for the price it is marked at, the sub is made pretty well. Would fully recommend it to any one replacing there factory sub or to any one who wants just that extra kick, but nothing to extreme.

I bought this speaker when it was on sale for around $20 with shipping. I put it in a small ported box with a 300rms amp and this thing sounds really good. I wasnt looking for extreme eargasm bass just some fuller sound and this sub hits the spot. It has a nice range even hits the lows on most songs without a problem. Overall a real nice speaker for its size and price range.
