T1D415

The T1 sub delivers on such an amazing level that I can't put what I want to say into words. So I will keep this short as possible. If you want to have outstanding bass with high spl this is your sub. On the other hand, if you want sound quality then this sub will also please just about any audiophile. Just remember, if you want spl go ported, and if you want sound quality go with a sealed box. Like I said from the start, the T1 sub DELIVERS.

Good old Fosgate Power!

Installed this sub in my friends 98 Grand Prix in a custom box and so far it has managed to break his trunk latch and shake his rear spoiler loose. It's also very durable, getting fed 1000 watts daily on music and it hasn't had a single problem to date. Overall a very solid woofer.

Low rumble

For the first time, I am at a loss for words, from the moment you pick this sub up you will notice what a real sub feels like. There is nothing negative I could say, no bad comment, and no regrets. I listened to several songs, and no matter what type they sounded great. I have two in a ported box in a Nissan Versa hatchback. They are driven by a RF T-1000-1 constant power amp. If you can, get them and have no regrets.

I have two of these on a T1500-1 bd amp and they perform better
than any sub I have had in my Nissan Versa hatchback.
If you have the funds, I'd say buy this sub knowing that it
is money well spent.
P.S. I love the ability to switch between 2 or 8 ohms with just the
flip of a plug, and best of all only one pos and neg hook-up.

Updated Review

I had two of these on a Rockford T 1000-1bdcp and thought that was great, but then I put a Rockford T 1500-1bdcp on these subs and they took the word bass to a whole new meaning. These subs made everything in my Nissan Verse hatchback shake. The T 1000-1 amp is great, but it had these subs under powered. The tech at Sonic was correct, these subs on a Rockford T 1500-1bdcp is wicked strong. I highly suggest you get one or two if you can fit them in your ride.

Awesome sub. Hits hard! Highly recommended. I have one and it's louder than my friends two kickers.
