REALLY GOOD

The following review is for a previous version (GP12D4).

This sub is really good, kicker is good but this sub hit harder than kicker CVR124, I couldn't believe. I would recommend this sub to any body.

GREAT SUB

The following review is for a previous version (GP12D4).

I have two of this sub and i can tell you they slam very hard. I choose them over Kicker.

Ground Pounder indeed!

The following review is for a previous version (GP12D4).

I have one of this in a custom 2.3cu.ft ported box tuned at 40Hz. I was a little skeptical at first because of the price I paid for this sub. But after tuning and playing the right bass notes for its box, man this sub really pounds, hard! And the bass production, man it is very clear! I am feeding it with 900w of power and yet it seems the power is still not enough. Really worth your money!

Good Buy

The following review is for a previous version (GP12D4).

I have one Crunch GP12D4 in a SB Probox, on a Crunch 1000 watt monoblock in my explorer, and it hits hard. The best thing is the sound quality, with all the subs i've had this is the cleanest sounding one. Good buy for the money.

Great value

I got two of these in a ported box recently and I'm thoroughly impressed. Even with only 160W going to each (4ohm load on an R500-1) they really pound, much much louder than my 2 old Kicker CVR102s. Only thing I regret is the fact that I overpaid by about $100 by going through the local car audio retailer instead of just buying everything here. Regardless, I'm completely satisfied with these subwoofers.

alright for the price.

These 12s have 250 Rms and with a well powered sub u can get some descent sound from them. I have 2 of them connected to a 1200 wat pyle amp and they have lasted for over a yr without a problem, and now I have just one connected to the amp and it hasnt overpowered of blew so its a very solid sub.
