## Overview

The Rockford Fosgate P300-12T Punch is a compact, sealed 12" subwoofer enclosure with a built-in 300-watt Class-D amplifier. Designed for trucks and versatile audio setups, it features adjustable low-pass crossover, bass boost EQ, and phase control for tailored sound.

## Description

The Punch 300-12T is a self-contained subwoofer enclosure with built-in amplifier. This "all in one" solution is great for systems that need extra Punch on the low-end of the frequency spectrum. The 12" high output subwoofer is impedance optimized for the built in 300-watt class-D amplifier that features a low-pass crossover, bass EQ and phase switch. The enclosure can be connected via speaker level inputs for connection to factory systems, or traditional line level inputs for aftermarket systems. It also features an intelligent auto turn-of/off circuit that eliminates the need for a separate turn-on wire. The enclosure itself is precision designed and constructed using MDF (Medium Density Fiberboard) for the best acoustical properties and covered with heat activated vinyl finish to resist marks. Dimensions: 15" x 25.8" x 4.8" x 8.5"

Review: Put this on my 22' pontoon and the difference is night and day. It is PERFECT for music. The sealed design and built in crossover lets you dial it in to give the perfect punch for music without being boomy or obnoxious. Super punchy, very tight, very responsive bass. Can feel it in the water when swimming! No distortion even at high volumes, no rattles, just pure tight deep bass. And it is super compact and a very quick/easy install, all for under $200! I can confirm the auto on/off function works great as well. This was a big time saver as I just mounted the sub in my 12v battery compartment, connected power and then ran line out from head unit. It comes on automatically when radio turned on, shuts off promptly when signal goes away to avoid phantom power draw. No need to run a remote turn on switch. Awesome!
Review: Conforme aux détails inscrits, facile à installer, très bonne sonorité.

## Questions & Answers

**Q: I was comparing the p300-12T to the same one listed on Crutchfield and the dimensions are different.  Has this been redesigned?**
A: I think it is the same sub. Crutchfield has the wrong dimensions listed for the P300-12T. It is 25.8" wide. Amazon has the correct dimensions. I received mine the other day, and I was glad to see that Amazon had the correct dimensions. Amazon also has a much better price.

**Q: Can i use rf discount code through your amazon store?**
A: not my store

**Q: Hey just wondering could i build a ported box for a sealed P300-12T subwoofer?**
A: They sell a ported version.

**Q: So this is my first time getting a sub and it’s all in one which is nice what do i need exactly i got the wiring kit 8 gauge and rca adapter**
A: You need to run a solid copper ground wire, at least as thick AWG as the power wire (sounds like you’re using 8 AWG), from the sub’s ground input to your vehicle chassis. Make sure the ground point is good  (use a multimeter to test). You may need to grind some paint off a metal surface to create a solid ground to the chassis.

Run your power cable from the battery to the sub. Use a 75amp fuse on this run. Connect the fuse closer to the battery than the sub.

Run an additional, very thin gauge wire (such as 18) to the amp turn on of the sub input. This wire controls power to the sub , so you don’t want it always on because that would drain your battery. You can hook up your car’s antenna 12v to this sub turn on, for example, since the car automatically turns off power to the antenna.

The RCA you can either run from some existing speakers using a LOC or run the RCA connected directly to your head unit (stereo).

In my Mustang, I used a LOC to connect the sub directly to my rear speakers in the trunk. I also wired the sub turn on wire directly to my antenna turn on wire because that is also conveniently in my trunk.

*by H***N on 20 November 2025*

Sounds great, obviously won't hit like a full size 12, but it's not bad at all for a shallow 12. Makes good full sound in a small car. If you're short on space it is a perfect option, definitely not underwhelming. Easy to remove if you need more room all connections are on a single plug so you don't have to remove the fuse or anything. Rockford Fosgate never dissapoints.
