Our take on the Rockford Fosgate P300-8P 8" 300-Watt Powered Subwoofer Enclosure

The Rockford Fosgate P300-8P is an all-in-one powered subwoofer enclosure: an 8-inch high-output woofer, a matched 300-watt Class-D amplifier and a pre-tuned box in one unit. It is meant to add real low end to a factory or aftermarket system without building a custom setup, and its compact sealed-style box takes far less trunk space than a separate sub, amp and enclosure. Rivals in this class, such as the Kicker Hideaway and JBL BassPro lines, compete on size and mounting flexibility; the P300-8P leans on its matched amp and woofer and Rockford's car-audio reputation. It suits shoppers who want simple, clean bass rather than maximum output.

About the Rockford Fosgate P300-8P 8" 300-Watt Powered Subwoofer Enclosure

The Rockford Fosgate P300-8P is a compact, all-in-one powered subwoofer. It pairs an 8" high-output woofer with a built-in 300-watt Class-D amplifier in a pre-tuned enclosure. It adds low-end output to factory or aftermarket systems without a separate amp, sub and box.

It works with factory or aftermarket radios and accepts high-level (speaker wire) and low-level (RCA) inputs. Auto turn-on means no remote wire is needed in most installs. A quick disconnect power plug makes removal easy. Its small size suits trucks, SUVs and cars where space is limited.

The enclosure is 5/8" MDF with a heat-activated vinyl finish. The amplifier has an extruded aluminum heatsink and built-in thermal and voltage protection.

Questions and answers

Is the P300-8P worth it over a separate sub and amp?
For most shoppers, yes. The woofer, 300-watt amp and pre-tuned box come matched, so you skip choosing components and building an enclosure. A separate setup can play louder for more money and space.
How much bass does an 8-inch powered sub give?
It adds solid low end and fills in what factory speakers miss, but it will not shake the block. If you want heavy output, step up to a larger or ported system.
What do I need to install it?
A power wire with fuse from the battery, a ground, a remote turn-on lead and an audio signal from your head unit or line-out converter. The amp is built in, so no external amplifier is needed.
Does it fit in a small trunk?
Its compact enclosure is one of the reasons to choose it over a separate sub and box. Measure your space before buying, since the box still needs room to load and breathe.
Can I keep my factory radio?
Yes. You can feed it from speaker-level outputs with a line-out converter, or use a head unit with subwoofer preouts for cleaner control.
How does it compare with the Kicker Hideaway?
Both are compact powered subs. The Hideaway is designed to tuck under or behind a seat, while the P300-8P is a box-style enclosure. Pick based on where you can mount it and how much output you want.
