GREAT SUB!!!!!

This sub is awesome I have just one 12 ' Kappa in a sealed box and it vibrates everything with low hard hitting deep bass this sub sounds and hit's better than two other sub's . I would like to hear how two Kappas sound at once!

this is the best sounding sub you will get!

Simply Amazing

I Have 2 of these in my girls car hooked up to a 2 channel 800 watt amp so there both getting about 400 watts each and man these things pound!!when i bought infinity i was expecting just sound quality not really loudness but i was wrong these things not only sound amazing but when i turn them up they can really BUMP and these things can hit deep to in my ported box which is perfect for me because i listen to alot of rap music so overall this is an amzing product and i would recomend infinity products to anyone!! simply amazing

great subs

I installed 2 of these in a GMC extended cab truck under the back seat and they sound great even with only 600 watts to them, they could handle alot more power. Nice subs.

Nice sub

Bought this along with Infinity door speakers for a complete new system. Very nice sub woofer. Very tight bass in the closed box I installed it in. Sounds amazing. Highly recommend.

Great Buy

These Subs hit very hard... they probably do over 350RMS to be honest. My mirror all 3 of my rear view mirrors shake. I bought 2 of these from SonicElectronix, and the Kappa series were cheaper here than the Reference Series(the lower grade of these) where at B.Buy... anyway these subs sound great, i've had them for 2 weeks now and they sound GREAT!!!

Good Alternative Rock Sub, not for Speed Metal !!!

I bought two of these to put in my 06' Scion Tc for the purpose of adding some bass to back the infinity Kappa components that went in my doors. These subs can sound excellent with good alternative music, my favorite band is 311 and these make the songs come alive like I'm sitting front row at their concert. If you like faster rock music than you should go with the Kappa Perfect's, they are better equiped to keep up with more Speed Metal bands. Simple bass beats much like whats in rap and R&B music these tackle that style easily. I have them installed in a sealed 1.0ft3 box which is the size required by infinity and this will aid the rockers who want clear bass. They are being powered each by a monoblock Profile California Series 700 watt amp, which gives them the required 350 watts of rms. Overall these complement my system great, but if your looking for a killer bass sub your not going to find it here.
