Conclusion: I've had many subs and this is by far the best. Its 1200 watt rms is underrated, im putting clean 1400-1600 watts all day with the right box it can handle that. specs are around 3 cubs im running a 5 cube box tuned to 35 and it hits the lows like crazy and still has highs.
Conclusion: I built a ported box to 3.28 @37 hz and also hooked up from Sonic a new hifonics brutus 2400 @1 ohm then tuned system with o-scope, which i highly recommend because signals start clipping before you can hear it.
Conclusion: I ordered one of this subs from Sonic Eletronix and I recived it two days early which was a plus for me. I just hooked it up and it is awesome im I just started breaking it in and even at quater power this thing makes my whole truck pound.
Conclusion: This sub is unbelieveable.... I know the price may seem scary to some people but if you are looking for loud crisp sound this is well worth it... I have this sub in an 01 Monte Carlo and it pounds... I highly recommend this sub to everyone out there..
Conclusion: I got one of these subs in my car in a custom box to specs in my altima and it just pounds. I'm running it off a mcd1100.1 and its taking that with no problem. Have owned plenty of subs from JL, Kicker, Orion, Memphis, Eclipse etc, and by far think this one sounds best.
Conclusion: This T2 is a beast. I have 2 of them being pushed by a T40001bd and they are loving the power. I first had them in a sealed box and they sounded clean, clear and loud. Now in the process of building a ported box to unleash the full potential of the beasts. Sound quality is similar to a JL W7.
