Product Reviews For Rockford Fosgate T115D4

  • Hits hard. I have 2 of these in a slot ported box and i'm only giving them 536wRms and they hit. Could use a great deal more power, you can tell. All around loud and hits hard. Your gonna need a powerful amplifier for this monster.

  • These subwoofers hit Very Loud Low Bass! I have 4 of them on 2 1,000 watt MB Quart amps in two seperate boxes that are 4.5 cubic ft. each and they Hit Very Hard! I have had a L7 15 before and I would compare them to a L7 15 Solo-Baric!

  • I was very impressed with this sub. I have one running on a 1200.2 rockford amp. it pounds. I would say it blows kicker's L7 (I had a 15" hooked up to the same amp and blew it in 2 days) way out of the water

  • This sub is great. I'm powering it with a RF p600.1bd in a 3.25 cubic foot box tuned @ 32 htz. It hits hard and VERY low. Pounds harder and sounds way better doing it than my friend w/ 2 Kicker CVR 12's in a ProBox. Just look around at the 15 inch subs from other brands and find a 220 oz magnet on one. This sub weighs 51 freakin pounds. Buy it, put the right power to it, and build your own custom enclosure.

  • The fifteen inch subs are the way to go. I have two in my 03 devill and powering it with the p8000s amp. Hits harder than any other subs I have ever owned. And they are very affordable.

  • 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!!!!

  • 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'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.
