Unbelieveable

I own two of these monsters. I knew they were great speakers but could not believe what they can do. The hard hitting bass is stunning. Powered with a good amp and the speakers will laugh in the amount of bass you can pump through them.

UNREAL DEAL! THESE RETAIL FOR $450 EACH!

Well put it this way, they are LOUD! These subs are crazy and im running them in a box built too small for them mainly the frequency is not right but still. Im planning to build the exact recommended box(according to ROCKFORD FOSGATE.com) asap. But im very pleased with them but mostly with how much i saved with sonicelectronicx. THANKYOU THANKYOU

I have 2 of these with a 1600rms Hifonics amp.. and holy crap..u cant hardly breathe in my Toyota 4runner.. i was sitting in the yard listening to them and after about 5 minutes. i had to get out because i was getting light headed ...definitely the best subs i have ever heard..i use to have an l5 but sold it and got these..very glad i did that..my friend has three alpine type x's and mine hit harder than his..very very pleased...cant imagine the t2's....but overall well worth every penny

Amazing Sub!

I used to have 2 Kicker CVR's in the kicker ported box. It was loud but I wasn't satisfied. I upgraded to 2 T1's and man ! It was a big difference.
I can't turn it up all the way . It hurts my ears and I'm afraid my window is gonna blow. lol This subs hits so hard . Its loud period. Definitely worth it !

AMAZING!

I have two of these in a ported box with only a 1000 watt kenwood amp giving them about 200 watts each out of 600 rms each and they POUND! I have the loudest system at my school and they are only getting 1/3 of the power! I am fixing to buy the Rockford Fosgate t-1500bd amp and i cant even imagine what they r gonna sound like!

Great Sub

I was skeptical when first purchasing this subwoofer but now i am very glad I did. I am running 700 watts RMS to it from a hifonics amp. It blows away my buddy's p3 and my other friends sony woofer. good buy just make sure you set up the deck and amp right and this thing will straight up slam! everyone elses subs have blown up at least once but this thing just keeps thumping.

Great sub

This sub hits hard by itself let alone if you pair it up with another. for this price this is a great sub to start up your system. I've got it hooked up to a 600W Alpine amp and it adds plenty of bass to your music. Granted, one of these won't shake your mirrors but it will rattle everything else.

Bass Killer

I own 1 T112D4 right now being pushed by a Kwood 9102d amp, in a '97 Satty SL2. and it sounds sick, I know a lot of people have kind of left Rockford's side because they don't make subs like they used to...not in this case, I used to have 2 HX2 12"'s and I think this hits just as good as the HX2's used to. If you want a good high quality sub that will beat the neighbor's head in or win some comp's get this sub!

Great sub

I managed to pick one of these bad boys up at a pawn shop still in the box brand new for cheap. It is a beast. It looks pretty much bullet proof. I really enjoyed listening to lil jon on this one. It made my seat shake like crazy. It has the capability to shake your seat at 12 hz in a sealed box. Its impressive. If your looking for sound quality and spl, this sub is for you. You wont be disappointed.
