Our take on the Alpine PWE-S8 8 Inch Underseat Sub Bundle

The Alpine PWE-S8 is a powered 8-inch subwoofer in a shallow, cast-aluminum enclosure designed to slide under a seat. It has a built-in 120-watt RMS amplifier, so it needs only power and a signal, no separate amp. It suits drivers who want real low-end in a tight cabin without giving up cargo space. Against passive 8-inch subs it is easier to install but less upgradable, and it will not match a large ported box for output.

What reviewers say

Owners generally like the compact size and the simple install, and say it adds noticeable bass to a factory system. Many note it is not a window-shaker and sounds best with the seat and trim left clear around it.

Questions and answers

Does the PWE-S8 need a separate amplifier?
No. The amplifier is built into the enclosure, so it needs power, ground and an audio signal only.
Will it fit under my car's seat?
It is designed to be shallow, but clearance varies by vehicle. Measure the space under the seat before buying.
How much bass does an 8-inch underseat sub give?
It adds noticeable low end to a factory system, but it is not a substitute for a large ported subwoofer.
How do I connect it to a factory stereo?
It accepts speaker-level input, so it can tap the factory speaker wires. A line-output converter is not required for most setups.
Is it worth it over a passive sub and amp?
It saves space and install time. A separate amp and sub give more output and tuning for roughly similar money.
Where is the Alpine PWE-S8 8 Inch Underseat Sub Bundle cheapest?
At Newegg, for $499.94, as of our latest check.
