Does it need a separate amplifier?

No. The amplifier is built in, so it takes power, ground and an audio signal and runs on its own.

Will it fit under my car seat?

It is about 2.76 inches tall, so check the clearance under your seat before buying. Seat rails and motors often leave less room than expected.

How does it compare with a 6-inch underseat sub?

The 8-inch driver moves more air than the common 6-inch units, so expect more output and lower reach. It is still not a match for a large boxed subwoofer.

The subwoofer and its wiring are the expected contents, but the listing does not detail them. Confirm the included cables and hardware with the seller before ordering.

Can I install it myself?

Yes, if you can route a power wire to the battery and a signal wire from the head unit. A line-output converter may be needed with a factory stereo.

Our take on the Underseat Car Subwoofer 8in with Built in Amp

This is a slim 8-inch powered subwoofer meant to slide under a seat, measuring about 9.45 by 12.2 by 2.76 inches. The built-in amplifier means no separate amp to buy or mount, and the aluminum alloy enclosure is light and sheds heat. It suits drivers who want more low end without giving up trunk or cabin space. Against typical boxed subwoofers it trades deep output for a flat, hidden footprint; against other underseat units the 8-inch driver is larger than the common 6-inch class, though no power or frequency figures are published.
