Our take on the Rockville RMW8P 8" 800w Shallow Car Subwoofer+Tunnel Slot Ported Sub Enclosure

The Rockville RMW8P is a loaded 8-inch shallow subwoofer in a slot-ported enclosure, sold with the driver installed, wired and ready to connect through a five-way binding post terminal. Rockville rates it at 800 watts peak, 400 watts program RMS and 200 watts continuous RMS, CEA-2031 compliant, which is high power handling for a compact shallow 8. The slot port is tuned to squeeze deeper bass out of a small box, so it suits tight trunks, hatchbacks and truck cabs where a full-size box will not fit. Against typical 8-inch loaded enclosures, it trades some ultimate output for a very small footprint, and the included grille and carbon-fiber-trimmed carpeted box make it a complete drop-in package.

About the Rockville RMW8P 8" 800w Shallow Car Subwoofer+Tunnel Slot Ported Sub Enclosure

The Rockville RMW8P is an 8-inch shallow car subwoofer in a compact slot-ported enclosure. The driver is tuned to a tunnel port system, which gives deep bass from a small box and takes up less vehicle storage space.

The subwoofer comes with the woofer installed and wired, ready to connect through a five-way binding post terminal. The enclosure is CNC-cut MDF, trimmed in a carbon fiber pattern wrap and automotive carpet. A black-on-black Rockville logo is embroidered on the front baffle, and a steel mesh grill protects the driver.

It is CEA-2031 compliant. Power is rated at 200 watts CEA RMS, 400 watts program RMS and 800 watts peak. The driver has a 1.5-inch high-temperature 4-layer Kapton voice coil and a talc-filled polypropylene molded cone. The suspension is a linear progressive spider with a double laminated surround stitched to the cone.

Questions and answers

What power does the RMW8P actually handle?
Rockville rates it at 800 watts peak, 400 watts program RMS and 200 watts continuous RMS, CEA-2031 compliant. Match an amplifier near the 200-watt continuous figure for daily use.
Does it come with the subwoofer installed?
Yes. The driver is mounted and wired inside the enclosure, and you connect your amplifier to the five-way binding post terminal.
Will it fit in a small trunk or truck cab?
It is built as a micro enclosure for tight spaces, which is its main selling point. Measure your mounting area against the box dimensions before buying.
Is a ported box better than sealed for an 8-inch sub?
The slot port adds output and low-end extension that a sealed 8-inch box usually lacks. The trade-off is a less tight, sometimes boomier sound.
What is in the box?
The loaded enclosure with the woofer installed and wired, plus a protective grille. An amplifier and wiring are not included.
Can I use it with a factory stereo?
Only with an amplifier and a line-output converter or a factory integration module. The sub needs a dedicated amp to produce bass.
Where is the Rockville RMW8P 8" 800w Shallow Car Subwoofer+Tunnel Slot Ported Sub Enclosure cheapest?
At Walmart, for $69.95, as of our latest check.
What do buyers say about the Rockville RMW8P 8" 800w Shallow Car Subwoofer+Tunnel Slot Ported Sub Enclosure?
