True Power You Can Feel

The T1D415 Power Series 15" Subwoofer by Rockford Fosgate has a peak power rating of 2000 watts and a RMS rating of 1000 watts. This sub will produce some ground shaking bass and is constructed with a kevlar fiber reinforced semi pressed paper cone and a VAST santoprene rubber surround. This woofer is also equipped with Inductive Damping Heat Sink, this helps radiate heat to reduce the voice coil temperature and keeps the sub operating at a safe operating temperature when pumping out high amounts of SPL. Add some bumps in your trunk and enhance your cars stereo system with this Power Series Subwoofer.

 
Rockford Fosgate Swift Terminals

SWIFT: Selectable Woofer Impedance Fused Termination

Making installation faster and easier, Rockford Fosgate developed SWIFT terminals. This system allows the nominal impedance of voice coils to quickly be configured in a Series or Parallel wiring configuration. Removing and inverting the center plug, a Series or Parallel wiring configuration is accomplished. The removable jumper also provides fused protection in severe overload conditions.

 
 IDHS Inductive Damping Heat Sink

IDHS: Inductive Damping Heat Sink

By securing the Inductive Dampening Heat Sink (IDHS) to the top of the magnet structure, Rockford Fosgate is able to improve the efficiency of their drivers. This is accomplished by reducing the amount of distortion and back Electro-Magnetic Force (EMF). The IDHS also radiates heat to reduce the temperature in the voice coil.

 
Anodized Aluminum Voice Coil Former

Anodized Aluminum Voice Coil Former

By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.

 
CEA-2031 Rockford Fosgate Subwoofers

Conforms to CEA-2031

Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.

 
Rockford Fosgate Stitched Tinsel Leads

Stitched Tinsel Leads

To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

 
Rockford Fosgate VAST Surround

VAST: Vertical Attach Surround Technique

In order to increase the surface area of the cone without causing any installation issues, Rockford Fosgate designed the Vertical Attach Surround Technique (VAST). By redesigning the manner in which the surround adheres to the basket, these speakers gain up to 25% more effective radiating cone area. This improves the nominal efficiency and maximum output.

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.

T1D4-15

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.

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.

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.
