Too Much Power To Handle

The T2D412 Power Series 12" Subwoofer by Rockford Fosgate has a peak power rating of 2400 watts and a RMS rating of 1200 watts. With this much power you can rest assure that you will be the envy of your block, as you stroll down your street with some car rattling bass. Constructed with a hard anodized cone and dust cap for strength and durability the Power Series subs will keep going now matter how long your listening sessions last. Also equipped with Inductive Damping Heat Sink, that 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. If you are looking to take your car audio system to the next level, the T2D412 will not only overwhelm you but simply blow you away.

 
Aluminum Dust Cap Cone

Aluminum Dust Cap & Cone

To increase the strength, weight, and thermal capacity of the subwoofer, a hard anodized cone and dust cap has been used. A Parabolic triangular cone support is used to reduce piston flex and cone distortion. The result is excellent heat transfer, reduced distortion, higher power handling, and a better sounding subwoofer!

 
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.

 
Rockford Fosgate inverted mounting

Reverse Mounting Compatible

The removable trim ring can be installed in the front or back side of the subwoofer. This enables the subwoofer to be mounted in either direction. No matter which way you install the subwoofer, it will still look great with a cosmetically finished look. Inverted mounting of the sub shows off the large magnet structure of this giant subwoofer.

 
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.

I have 2 of these

I have these powered by a T2500 cp and it POUNDS! My windshield needs to be reinstalled because it blew the seal! These subs sound great and shake my neighbors house so bad he complained about stuff falling off his walls!

Amazing quality, Could not be happier!

Ordered a set of these for my '98 Cirrus. One of the main reasons I ordered these was the material and craftsmanship. My last set of subs also had an aluminum cone, and I adored them to no end! I could not bring myself to pay this kind of money for a sub with a paper cone (and yes, I know some brands make better subs with paper cones, they just aren't for me). When the subs finally came in, they were just as impressive looking as I had hoped! The build was fantastic! The spring terminals were very strong, no fear of the wires shaking loose! They are loud and proud even with only 500watts each! Can't wait to have my local shop build a custom box for em, and get a T1500 amp for these bad boys later on down the road!

not all that

I have a Rockford Fosgate 3000.1 BD amp. My Kicker l 5 blew, so I got the T2D412 thinking it would be better. I was wrong. If I could send it back, I would get the Kicker L7. The Rockford doesn't sound that good or that loud. I thought T2 would sound a lot better then they do. They also can't handle the amp that well. Sonic did a good job sending these to me, but they are not worth the money that I paid for.

T2

These are the best subs on the market!!!!! Don't let any other sub get your attention. If you wanna be the best, you have to have the best, and the best is the T2s. i have 2 of these in the trunk of my skyline. I have two T2500.1 running 1 for each sub, and no one has every beat me at a competition. Btw this is the second time I've had this set up. The first time I got these subs they were taken from me because I got 3 sound violations and they took my subs.

Two T2D412 subs pound! Even better in a custom Rockford spec box!

I have these subs set at 3 on my gains on a T-2500bdcp and I haven't even budged it over 3 and at full volume they POUND no joke, your tonsils will be dancing and your passenger will be shocked at how loud these 12's will hit. Rockford all day, everyday!

Slams

These subs will drop some lows for sure unfortunately my box and port is too small even with them inverted,it was built for my old (silver) T1D412's and isn't near enough for these subs full potential output. I'm currently looking into buying/building a proper sized box for them to get the most out of them. Powering 2 of these T2D412's with a RF T2500.1bdcp amp and it just hits crazy hard,just posted a review of that amp as well,great combination

Monster in my trunk

The guys or so different from other subs. If you need something that makes your car shake then these are the beasts that you should have in the trunk. I prefer these in a bigger car cause putting these in small cars will screw your car up. By the way To make them sound better you need a bigger amp.
