T1 - my first rockford sub

I am bumping loud and clear. I owned subs from The most popular of brands. Type R, jls, kicker, interfire, etc. My T1 kicks more than ass it kicks body . Thanks for making an
awesome sub.

T1 subs are #1

My wife recently bought me my first T1D412. I got it 2nd hand. I have ran kicker,jl audio,mtx,sony,and eclipse subs in the past. I will say by far that this subwoofer in the right size ported box will make your eyes raddle inside your head. My coworkers hair was vibrating when he sat in my truck to check it out. !!!UNBELIEVABLE !!! I love this subwoofer and am saving to buy another. Thank you Rockford Fosgate for building thse power series subs.
