8-Inch Amplified Subwoofer System

The Planet Audio PAB80 is a self-contained 8-inch subwoofer with a built-in amplifier, delivering 125 watts RMS and 250 watts peak power. It suits drivers who want stronger low-end output without assembling separate components.

Straightforward Install With Basic Wiring

The enclosure arrives pre-wired, so only power, ground and signal connections are required. A 4-ohm single voice coil keeps the wiring simple, but the 10-inch mounting diameter means the cut-out must match that exact opening or the unit will not sit flush.

Check Available Space And Signal Source

Verify the trunk or cargo area can accommodate the full enclosure dimensions before ordering. You also need a head unit or processor that provides a low-level RCA output, because the internal amplifier does not accept speaker-level inputs.

Questions about this item

How can I confirm the subwoofer is working correctly after installation?

Play audio and verify bass output from the 8-inch cone; adjust the variable bass boost and subwoofer level control, then use the 0-180 degree phase switch to align timing with your main speakers for coherent low-frequency response.

What comes in the box and what must I purchase separately?

The amplified subwoofer system with enclosure is supplied as a single unit; you will need to provide power and ground wiring, a remote turn-on lead, RCA signal cables, and a suitable fuse holder for the 125W RMS amplifier.

Which version or capacity should I choose for my system?

This model is offered in a single 8-inch configuration rated at 250W peak and 125W RMS with a 4-ohm single voice coil; select it when your amplifier or head unit can deliver up to 125W RMS into 4 ohms and you want a compact enclosed solution.
