Review: Definitely get it if you’re on a budget!! - Honestly was better than I was expecting and heavier than it looks sounds amazing and was pretty easy to wire to my existing setup I think my only gripe is it gets really hot but other than that everything works perfectly and it’s great for a budget setup
Review: Pleasantly Surprised - I purchased this because my son wanted to add some extra bass to the factory system in his 2013 Ford Fusion. I've never been a fan of trunk-rattling subwoofers, but thought this under-seat model would be enough that he could hear/feel that extra low end and get a bit more out of his music. I was a bit skeptical seeing as how compact this model is, but we were both very surprised. Like other reviewers have said, don't expect this to wake up the neighbors. However, it's enough to round out the lower end of the sound spectrum and take some strain off of your woofers. Setup was fairly simple once we figured the best way to get through the firewall and wire it to the battery. The onboard controls make it a cinch to dial in the right frequency range, volume, and gain to complement the factory speakers. Our next step is to attach some passive crossovers to his door speakers and let the Wheel of Bass do the heavy lifting.

## Features

- SLIM DESIGN FITS ANYWHERE: At only 3.15" tall, this subwoofer slides under seats or fits in tight trunk spaces, delivering powerful bass without sacrificing room. Ideal for trucks, cars, or compact vehicles needing a space-saving audio solution.
- POWERFUL 500W BASS OUTPUT: With 500W peak power and 125W RMS, the WHEEL OF BASS produces deep, clean bass. Adjustable bass boost (0-12dB @ 45Hz) lets you fine-tune sound for music genres like hip-hop, rock, or EDM.
- EASY INSTALLATION: Built-in amplifier and high/low-level inputs simplify wiring. Auto turn-on technology activates the sub with your audio signal, making setup quick for factory or aftermarket systems. Includes mounting hardware.
- DURABLE CAST ALUMINUM BUILD: The solid cast aluminum enclosure stays cool and withstands vibrations, ensuring long-lasting performance in rugged conditions like daily commutes or off-road adventures.
- CUSTOMIZABLE SOUND CONTROLS: Features a remote bass knob, phase switch (0 degree/180 degree), and low-pass filter (50Hz-180Hz) for precise audio tuning. Subsonic filter (20Hz) cuts inaudible frequencies for clearer sound.

A: The warranty is 1 year through Rockville. The product came with all plugs necessary to connect to my Sony head unit. It's a great product that works well in my Toyota Land Cruiser.

### ⭐⭐⭐⭐ Standard setup if you are familiar, decent bass increase
*by M***Z on October 22, 2024*

Put this in my 2018 Sierra Crew Cab, biggest issue (as always) Is getting power through the firewall (need your own 10G or heavier line...I used 8G). Once connected and past the initial issue of protect light (reseating cables addressed it) it powered on and once phase, gain and frequency set it was noticeably better than stock door speakers. The only complaint I have is that the remote nob doesn't make any audible difference in the level. I've got power to it but it doesn't seem to affect it. No big deal as the head units bass control controls it fine...just my reason for a stat off. Good little banger for 100 bux
