Q&A about compact powered subwoofers

A Crutchfield Advisor talks underseat bass


e field lots of calls from customers who want more bass, but are tight on space in their vehicles. That's when we start suggesting compact powered subwoofers, also called "underseat subwoofers" because that's where a lot of people install them.

To help answer some common questions about these small subs, I sat down with Crutchfield advisor and car audio expert, Cam, and asked him about compact powered subwoofers. But I'll start the conversation with the easy question: 

What is an underseat subwoofer?

An underseat sub is a small subwoofer with a built-in amplifier, housed in a single, compact body. This all-in-one design makes it easy to shop for and install a bass system for your car — you don't have to match a separate amp and woofer and then figure out how to best wire them up.

    I have a 2003 subaru forester and they sell an under seat subwoofer, but I want to choose something better, but still keep under seat. Will you have any harness/instructions to connect it to the factory wires already under the seat?

    Ti-Sheng, If you purchase your compact powered subwoofer from Crutchfield, you will also receive free tech support, which will help you with your installation. The wiring under you vehicle's seat may have nothing to do with audio or power.

    My truck has a factory sub already. It sucks. I am used to the old school way, new head unit, amps, subs, etc... I'm passed that now. Would it really just be as simple as removing the factory sub and installing the aftermarket one?

    Question coil I install one of these in my motorcycle saddle bag. Also would I need to use a capacitor because of the power draw

    Thomas, Yes you can install a powered sub in a saddlebag. You probably won't need a capacitor.
