I've had a pair of these T1s in a big box in my suburban for 6 years with a 2000 watt amp for each speaker &  holy sh@t the bass coming out of this system is earth shattering I haven't come across anyone who can out sub me anywhere & I haven't had any problems since buying & using them for 6 years! I would definitely recommend T1s too anyone who wants to sub on the next level.

I have had many different brand subwoofers from 10's to 15's and these 15' woofers are absolutely outstanding! I just can't say enough good things about them. If you build the enclosure to rockford's specs these things will POUND. I have them in my 05' altima hooked up to a RF T10001BD power amp. You need dynamat with these subs though. I also have a kinetik 1800kc battery in my trunk. These thing ROCK!!

I HAVE TWO OF THESE IN MY 2000 BUICK CENTURY AND IT SOUNDS LIKE AND EARTQUAKE!!! I HAVE THEM HOOKED UP TO A CHEAP 2000WT QUANTIUM AMP AND IT HITS WAY HARDER THAN ANY SYSTEM IN MY HOOD. WHEN THE NEW AMP ARIVES LOOK OUT HOOD!!!!
