Unboxing the Rockford Fosgate P500-12P

Rockford Fosgate P500-12P is a giant, heavy, and solid subwoofer, and we instantly realized it after receiving the huge box from the brand. Even though we were impressed by its packaging and how it came to its final destination despite its unusually big structure, we were amazed to notice the thoughts put behind the whole packaging for secure shipping.

Upon unboxing, we found the subwoofer covered in plastic material with the grille attached to it. We found no noticeable damages, so we assume the packaging material was of high quality.

We also found a user manual, warranty card, long power cord, and RCA connector in a box to get it started. 

Subwoofer Size

The first thing that matters most is the size of the car subwoofer. Unlike home theater ones, car subs require much attention due to car space availability.

Compact subs like the 6, 8, or even 10-inches are easy to manage and can be easily placed under the seats, trunks, and behind the rear seats, and small car owners can enjoy their performance.

On the other hand, Rockford Fosgate P500-12P demands another case. This 48 pounds subwoofer, measuring 12-inches driver, requires significant space and is designed for trucks, SUVs with massive cargo spaces, etc.

In short, the 12-inches subwoofer with a built-in amplifier, especially with a ported enclosure, will be a massive addition to the car. You must dedicate a space to it so it can settle in and perform to deliver immersive listening.


This all-in-one music solution comes in a ported enclosure with an MDF construction that keeps it reliable for a long time despite the intense punishments.

The subwoofer, with an enclosure, measures 15 x 24.76 x10.91 x 7.71 (HxWxD1XD2) and is ideal for hatchback or sedan applications. Besides, the enclosure has a power connector and input releases for quick hooking-ups without any hassle.

In addition, to give it an attractive edge, the round corners with a mesh grille play a part. The vinyl with leather texture at the end panels gives it a classy look that can add charm to your sedan and SUV.

Built-in Driver and Amp

Rockford Fosgate P500-12P only includes one 12-inches woofer that is present at the front and the class-D Amplifier that fuels the power to it.


You can find the built-in 12-inch woofer is based on the stamped steel basket that features six spokes. Around eight cooling holes on the basket and eight at the bottom helps with ventilation, making the hot air escape and keeping the voice coils cool by relieving the pressure.

Surprisingly, to release the pressure from the dust cap, Rockford Fosgate has designed a large vent at the bottom plate. Continuous ventilation from all sides keeps the subwoofer functional for a longer time and lets you enjoy the banging bass on your long journeys.

Class-D Amp

The 500W Amplifier is located at the right end panel. Rockford has designed it carefully to meet the power needs of a 12-inch woofer packed in an enclosed enclosure. Though the enclosure is quite convenient to remove, featuring 4-AWG terminals for power plug and ground connections.

Rockford Fosgate has a defined strategy for protection, hence the addition of 15-amp ATC fuse pair for over-current protection. A four-position Molex-style plug can be used to feed the signals to the amp.


Setting up and hooking the subwoofer to a receiver is a walk in the park. Low-level and speaker-level inputs give you enough room to make it functional in your sedan, SUV, or hatchback applications in no time.

The connections collection offers powerful output in low-end frequencies, so you can enjoy strong, stable, and heavy bass.


It is not surprising that the Rockford Fosgate subwoofer comes with multiple control levels that let you adjust the sound and bass quality per your preferences.

The amp features bass EQ, a phase switch, and an adjustable low-pass crossover to maximize the usage and output.

Moreover, the sub’s auto turn on/off function grabs attention. Enabling the function makes the subwoofer flexible enough to automatically turn on when sensing any audio signals and turn off when there’s no use.

Sound and Bass Quality

Rockford Fosgate P500-12P performs incredibly great with no muddy sound, and the low-end frequencies are pretty distinct from noticing.

Its upper bass attack is worth appreciating, and its ability to go down at 31Hz with the bass-heavy context also makes a difference. The frequency response range of 20Hz to 200Hz is the highlighting feature that makes it the best-selling product.

In addition, the dialogue clarity is absolutely stunning, and the rumbling sound keeps you hooked on the long roads. We didn’t hear any sloppy or muddy noises or distortion during the testing.

Besides, the subwoofer didn’t compromise on sound clarity or bass performance, even at extreme listening levels.

• Clear and rich bass
• Goes loud with individual bass notes
• Ported MDF enclosure
• Under voltage protection
• Convection cooling system
• Bass boost EQ
• Heavy
• Requires significant space

Bottom Line

Enjoying great bass at a high volume level in your Sedan or SUV is possible with the Rockford Fosgate P500-12P.

The engineers at Rockford have done a great job designing this well-balanced subwoofer that is perfect from enclosure to design, frequency to bass quality, and input to control levels.

Get a subwoofer and enjoy the hard-hitting bass in your vehicle.
