Boss Audio BASS600 8-Inch Low-Profile Amplified Subwoofer (Single)

I have purchased this subwoofer for my Honda Civic.
It really depends on quality of your headunit. One with sub dedicated output/preamp will work better than one without.
On my Pioneer headunit WITHOUT sub output/preamp, it did a good midrange at the best. Loud it is, but definitely not a bass loud. On my Pioneer heaunit with sub preamp/output, it's better, but I need to re-set it all now. I have Basslink200 passive subwoofer, that one outperfomed Bass600 absolutely on quality and thickness of bass, at basically same price.As a result, I replaced Bass600 with Basslink. Basslink is so powerful that I keep it in the trunk. When tried in the trunk, Bass600 produced almost no noticeable audio improvement. I guess, you can't beat laws of acoustics and expect much performance out of tiny metal enclosure.
It did not fit under the seat, which I really did not even expect, but hope was there.
Controls are retarded. You have to have a tiny screwdriver to turn the dials. Thus, every time you need to twick it, you have to get out of the seat, get to dials, turn them with screwdriver, get back in the seat, listen to it, and do over again. Lack of knobs does not permit simple reaching there and doing it, so adjustments "on a go" are impossible..
12V/remote/ground attachment is designed for thick wires, so I had to go creative on this. Installation took about 30 mins. Remote is quite useless.
It left me with that impression that whoever made it, had access to a bunch of old obsolete electronic components, and just slapped a sub together. I have not seen those adjustments dials used in years!

I recently purchased this amplified subwoofer for my Jeep Wrangler, and am completely pleased with the purchase. I had previously installed new Alpine 6.5 inch speakers but was missing the low end sound. In my 20's I had a jammin system but did not want that much base again in my 30's, this was the perfect choice. I had it professionally installed and even that person commented on how impressed he was with this product. I would definitely recommend buying this unless you want a big base bump, then go with a larger box, amp, and 12 inch speakers.

I bought this for my '94 Chevy Truck. I installed it under the driver's seat and it works exactly as I had hoped. I also bought the wiring kit with the #8 AWG power wire and regardless of some of the other reviews, it IS #8 AWG. The kit had more than enough wire to install the unit. The only drawback was that the fuse was bad right out of the box.
This unit drives just enough bass (when I have it turned waaaay down) fill to the void from the 4x6's that the truck allows in the stock speaker openings.
I didn't want to rattle the neighborhood, I just wanted some low-end when I'm rocking out and this amp provided it perfectly.
I install Home Theaters for a living and I know what deep bass is supposed to sound like. I've rattled many a picture frame off the wall with my theater systems. This sub will not do that cleanly, but if you're looking to fill the low end of your system without breaking windows and your wallet, this one's perfect.

I have had this in the system now for about 2 weeks. I'm pretty impressed with it. The sub does exactly what I wanted it to. I'm using it in a 95 Escort, under the passenger seat in with an aftermarket Pioneer head unit to factory speakers. Now, I will be upgrading the speakers, but the issue was I can only put 5 1/4 speakers in the doors and 5x7 speakers in the rear decks. I new this wouldn't give any low end and wanted to "thicken" up the bass.

That is exactly what this does. Plenty of power for this application... pretty tight bass sound, not real "boomey". I would recommend this for anyone looking for some low end into a non-amplified stereo configuration. If you are building a system from ground up with amps for all speakers, this is probably not the right application, but a great addition for what I'm doing, or adding a sub to a factory system.

I recently purchased this product to enhance the sound in my wife's Chevy Aveo5 with the standard factory system.

Product arrived in about 2 days using Amazon Prime shipping. Unit is heavier than I expected and external build quality is good. The installation went smoothly. I have it mounted under the driver's seat (in a small hatchback space is premium).

The user manual could be more user friendly, but once adjusted it filled out the bottom end really well. This is a really good small Subwoofer. The total wattage in the specs maybe misleading as this will not win any Bass wars, but it was not design to.

So if you are looking to fill out the bottom end with your factory stereo, give this sub at look.
