More bang for the buck

I went and got this 12" at BestBuy for 80 Bucks. Hooked it up to an 1000 watt amp in a sealed box and it hit! One of the best investments i've made in awhile. Can't wait to fully break it in and maybe even get another one.

Awsome sound ------ Great price

If your wanting a set of speakers that hit hard and aren't hard on the pocket book these are the ones. I didn't really know too much about Infinity 1252W's, but glad I bought it. The sound is clear, and really carries.

great subwoofer

I have one of these in a 1997 camaro. It will shake the inside of car really well. sound will leave outside some what. I have a 200 watt kicker on it. It can get a little boomy at times. It will also slap if over driven.great tone.music varies from metal to country.

awesome subs

I bought a pair of these from Sonic Electronix for a great price and I didn't expect them to be as loud an hit as hard as they do I built a custom box of 5.50 cu.ft an ported it tuned to 34 hz and they are in a tahoe with about 500 rms on each sub actually a lil more and my windshield wipers shake a lot to tell you how hard they hit I love them!

Nice subs

i bought two of these that had been used for a few months for $90. they sound really good and clear and are fairly loud. id recommend these for the price.

great sub for price..

this is one of the nicer subs in its price range.. I threw it in a sealed box for fast sq response and it was very surprising how nice it sounded.. if you are looking to slam this isnt for you.. if you are looking for cheap quality low end spectrum that keeps up great sealed then this is for you..

only thing i dislike is HUGE logo in the middle..
also my tinsels came loose.. nothing a little soldering couldnt fix

awesome

I replace the Kenwood in my commuter car with this one and I couldn't be happier! If I didn't already have an L7 in my other car I would throw a couple of these in! If your on a budget this sub is a need!

Great

This is a very good sub I have one and I'm using a SPL 520watt amp pushing it right at 300rms and it hits harder than 2 10"s I highly recommened this product.

Pretty Good Sound

Very versatile subwoofers. I have them in my car (2x12) with a 400 watt x 2 amp, and they sound pretty sick. They thump to rap and kick with metal, they handle almost any style of music, but they aren't the loudest things ever, and when the weather is JUST right they sound amazing. But often its too hot to get amazing hits out of them. I live in Florida. And its the summer.
