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.

    Are there any under the seat subwoofer that aren't powered or active but instead a passive under the seat sub and just run it to an amp? I just can't find anything like that. I have a 2013 ford f-150 4 door super crew and putting the subs under the rear seat just will not work because well that's where i have my tool bin. want something under the driver and front passenger seat. I will already have an amp for my door speakers so I figured I would go with a 5 channel amp and run the sub channel to those. Any suggestions? Thanks

    Juan, I looked around online and also couldn't find any non-powered subs that would fit under a front seat in your vehicle. You may have to settle for a powered underseat sub and a 4-channel amp.

    Will the output of the small powered subs like the Alpine get lost in a mid-size SUV along the size of a Jeep Grand Cherokee? Ideal placement would be under rear seats or in the cargo space. Not looking for mind-rattling bass, but the factory system is really lacking in the low end. Should I consider the slightly more powerful Rockford P300-8 or P300-10? Thank you.

    Scott, I think you'll be happier with the higher-powered sub.

    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?

    Buck Pomerantz from Crutchfield on 1/21/2019
    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

    Buck Pomerantz from Crutchfield on 11/24/2018
    Thomas, Yes you can install a powered sub in a saddlebag. You probably won't need a capacitor.
