Product Description

Style: 4-Ohm

Product Description

Rockford Fosgate Punch 2011 or newer P1 or P2 Series Subwoofer Grille. A cost effective way to protect your subwoofer. Uses existing subwoofer trim ring.


The Power Series T1D415 Dual 4-Ohm subwoofer builds on innovative new Rockford Fosgate technologies. These bad boys have patented "VAST" technology that increases surface cone area up to 25%, and the new FlexFit basket not only looks the part but provides extreme flexibility for your installations. Clean, high-tech, and ready to set off car alarms.

Rockford Fosgate Power Series Subs

These subs are big in every way. Rockford's engineers started with cast aluminum baskets and loaded in powerful linear motors. Add to that dual spiders, aluminum cones, and high-excursion rubber surrounds, and you get a sub that is both physically impressive and sonically overwhelming. Power series subwoofers deliver pounding bass, extreme low frequency extension, and serious power handling capacity.

T1D415 Features

Speaker Construction
  • Anodized aluminum heat sinking dust cap
  • Anodized aluminum voice coil former / copper clad aluminum wire
  • High-temp voice coil with spun-laced Nomex re-inforcement collar
  • Kevlar fiber reinforced paper cone
  • Optimized and matched magnetic and complicance geometry
  • Optimized pole piece and spider venting
  • Periodic-stitched fatigue resistant tinsel lead wire
  • Proprietary 8 AWG insulated allmetal input spring terminal connection
  • Rigid die-cast aluminum basket
  • Symmetrical dual progressive roll tear resistant poly-cotton spiders
Anodized Aluminum Voice Coil Former

Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.

Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle power under continuous damand, not instantaneous power handling, that over time, can damage voice coils.

IDHS Inductive Damping Heat Sink

Secures directly to the top of magnet structure to improve system efficiency by reducing both distortion and back EMF (Electo-magnetic force). Also radiates heat to reduce voice coil temperature.

Flex Fit Basket

The Flex Fit frame utilizes slots (where feasible) instead of single screw sized holes. This allows slight adjustment of the speaker when mounted.

Stitched Tinsel Leads

Multipoint "periodic" stitched lead wire technique reduces the mass of each tinsel lead and spreads stress and strain over a greater area, significantly improving the reliability and performance of the subwoofer.

These stitched tinsel leads withstand extreme duty cycles, fatigue and high current that is critical to robust design.

SWIFT Terminals

Removing and inverting the center plug, a Series or Parallel wiring configuration is accomplished. The removable impedance selection jumper also provides fused protection in severe overload conditions.

"VAST" Surround

The Vertical Attach Surround Technique significantly increases a speaker's effective radiating cone area without complicated installation issues. The result provides up to 25% more effective radiating cone area for the same model speaker.

I have never experienced bass like this before. I have owned Rockford p3 12's, 15's, t2 12's, and t1 12's and also kicker l7's. Let me go ahead and start off by saying that to really get what you need out of these subwoofers, EVERYTHING has to be done to a tee. Starting with your alternator. I own a "Mean Green" 325 amp HO alternator and that is just right for my setup, along with Rockford Fosgate 1/0 gauge wiring for my big 3 (I only trust O'Ryan and Rockford Fosgate with 0 gauge.) Secondly, you need a battery, particularly a subwoofer made battery (Kinetic, Shuriken, Stinger will work.) Also have a stinger battery isolator. Lastly, I highly recommend getting a low's equalizer such as the acoustic audio "epicenter." Have a Rockford Fosgate t400-4 on 4 6x9 and that is hooked up to a optima yellow top. The subs are powered by two Rockford Fosgate t1000bd amplifiers set at 85 percent gain. I have the 2 ohm version and let me tell you something that I have never experienced bass like this and this is exactly what I was looking for. The tremors in your throat, in your chest, in your stomach. It's orgasmic for lack of a better term. Have turned over at least 3 people to these subs and all have been highly satisfied. Have had them now for a year and a half and besides your basic tune ups, they have never had a problem. If you are willing to spend the money on a legitimate system and are willing to set-up your car correctly, these are the subs for you.

Never cared for Rockford subs until I owned this one. This is a great SQL driver, I have never heard kick drums sound so good with so much impact and tight. It will play low with ease as most 15's will do but it handles fast beats pretty well for a 15

I have it in a 3.10net custom enclosure with a 6" PSP port tuned to 33hz I designed and built on a Rockford P1000X1D and I am pretty sure it can take more power if its clean. Never have I smelt coil.

Sure there are better drivers and louder drivers but if you are going to play actual music this on is a go to

When this sub came in there was a label on the shipping package that said "Team lift". So, yes, this sub is super heavy. I also got a box to go with it (70 lbs.) and it takes up the space in the back of my 98 Blazer. It's not even broke in yet and when the really low bass hits, my roof and doors flex! I have a Rockford Fosgate class D 1000 watt (rms) mono block amp to push it. When you buy this sub you will be paying for quality and massive bass, not the brand name (like JL Audio). Make sure you have all the right gauge wire sizes that it specifies. I just bought a Rockford Fosgate 400w 4 channel amp to power my door speakers and tweaters because the bass drownds most of the highs out. I have'nt hooked up the 400w yet but when I do and the sub breaks in I can finally kick that bad boy into high gear! Over all, this is the best BOOM for your buck. 52% off original price. Was still in factory box with factory seals, perfect condition. When you go with Rockford Fosgate, you wont ever look at any other brands. HIGHLY recommended. Go get it!!

I am an installer i can have any subs i want,this is what i have in my own car.I have ran almost everything out there and this is one of the best subs i have every owned.The design keeps the voice coil cool even under hard use i love the double spider everything is super durable. I have put these in sealed and ported boxes and they have never failed to impress.As well as very high output and high power handling it's a very good sounding sub.I am running sealed in my own car and believe it or not i can even play rock music and it will punch like a much smaller sub,on the low it really comes alive.I am putting 1900watts rms on a pair and it's a great match,this same amp has blown mojo,mojo x and a few other 15s,i was not abusing them they could just not hold up to prolonged high levels like these T1s can.If you are investing in a high powered audio set up for you car this is the sub you want.It does everything right and nothing wrong.We have never had one blow or fail for any reason even with our abusive customers,they love them as much as i do.

I bought this along with a lanzar max pro 4000 watt amp witch works perfectly because this woofer peaks at 2000 watts at 2 ohms and the amp runs at 2000 watts at 2 ohms and its also 2 ohm stable! its almost like it was made for it. make sure you go with some quality 0 gauge wires with it and 12 gauge speaker wires. you couldn't ask for cleaner bass thats loud but still doesnt distort the audio! i also have a labyrinth box with a power port so you really get those lows. i love this thing!
