My buddy put 2 of these in this impala and they sound very clean hit hard as ever. After seeing that and how inexpensive they are i plan on hooking up four in these bad boys in the back of my car. (built for street and show) My neighbors should at me just that much more.

Purchased this sub because I was on a budget and read some good reviews about it here. I was very surprised to hear how good this sub sounds. Powered with a 250 watt RMS mono amp in a sealed enclosure in the back of my Explorer and this thing pounds!!

Review written by David from Ardmore, OK
well to start off the sound quality was decent! but the plastic caps over the magnets vibrate pretty bad. i have 2 of these and for the money none is better!

Review written by Austin from Springfield, MO
I have previously owned 2 of these subs, and you really cannot beat them for the cost! i have had a set of Kicker cvr's and they weren't as loud as these! I would say that there only weak point is the large ported enclosure size for a 12, None the less, I am currently about to checkout with 6 of them in my cart.

Thank you sonic electronix! once again you have proved to be the lowest on the net.
