Kenwood KSC-PSW7EQ Active Compact Subwoofer with Active EQ (160 Watt Output Power, Class-D Amplifier, Aluminium Housing, Cable Remote Control)

Bought one of these for my mk3 Toyota MR2. Fitted it behind the drivers seat and it sounds brilliant. Does help that car is small I guess but in my car it is more than powerful enough.

Tried it, can’t even turn the dial to max just distorts. Really bad bass not worth it.

This is a well-built unit that delivers good performance for the price and is easy to install if you've had any experience fitting car audio. it's important to note, though, that it's a SUBwoofer, which means it's all about the really low-end bass frequencies. If you want a regular woofer to give you louder bass throughout the entire bass frequency range, this *isn't* what you want.
