    • Good for bass shaker
Used for bass shaker. Bluetooth works perfectly. Too early to tell for frequency but gain and volume makes a big difference.

    • Saved my Subwoofer!
I had a 12” Polk Audio subwoofer on my home theater that the amp died on. I saw a guy on YouTube that hooked this amp up to a similar subwoofer with a dead amp and it worked great. Excellent solution and saved my sub from the trash pile.

I am using one of these units to power a kicker comp r dual 12" subwoofer enclosure and was blown away at how much power this little box can create. I had to turn the volume to halfway and the frequency to about 1/3 from full. I am once again sending a signal to it from a yamaha receiver. This setup is in my home gym. This would be perfect for some of you wanting to add a sub to your home theater as the car audio setups can be had for cheap on facebook marketplace or even on Amazon for that matter. *UPDATE* This is the finalized setup I am using. I purchased a Fosi Audio P1 Tube Preamplifier Mini Hi-Fi Stereo Preamp 6K4 Valve Vacuum Pre-amp with Treble Bass Tone Control for Home Theater HiFi System(not for Turntable). I was able to reset the subwoofer 2 output to 0 and I am using the preamplifier to adjust the feedback volume on the MQB-1 bass shakers. You can see the settings I am using in the pictures of the preamp and the subwoofer amp. This provides plenty of clean feedback at all volume levels. The preamp gets warm but the subwoofer amp stays pretty cool to the touch unless you are listening at a high volume level playing EDM sets for 2+ hours then it will get warm to the touch. I will update this post with any other mods I make but for now I think this is the best way to run a set of these bass shakers. I am considering upgrading to the larger Q10B bass shakers in the future.... I was very very hesitant to purchase this unit since trying to use the Fosi audio TB10D to power two MQB-1 Earthquake bass shakers resulted in a total failure of the unit.... I decided to give it a shot since fosi audios website recommends this instead of the TB10D to power bass shakers. I was pleasantly surprised when I turned it on and had everything on the subwoofer 2 output rca signal line zeroed out and I was getting some feedback from the bass shakers with a 30hz test tone. I turned the subwoofer 2 output up to +10 and turned the volume of the fosi unit down to about 1/3rd and I was still getting amazing feedback. I am running the MQB-1 bass shakers in parallel using a banana plug 2 into 1 splitter which results in a 4 ohm load. I am still in disbelief at how much power this little box produces to power 2 500 watt bass shakers. I had a behringer A800 on order in case this setup did not work and I have canceled that order since I will not be needing it anymore. The only thing I may add is a clearpro box to get the rca line signal zeroed out from the Yamaha receiver. Other than that this setup is working perfect so far.... I tested it at a fairly loud volume playing Rufus Du Sol Live from Joshua Trees 45 minute set and the fosi amp was warm to the touch. The next test is the 2 hour Camelphat 2023 live set from Creamfields (which is what ultimately blew the Fosi TB10D amp). I will report back if anything fails or goes wrong on my end but for now I think this setup will work and yes I am using the power supply that comes with the Fosi amp. If you are looking to power a set of bass shakers and have no issues adding a line driver if your rca signal level is low then I strongly suggest getting one of these units. I will update this review if anything goes wrong with it... In my photos I have included all of my settings I am using. I am using the rca output from subwoofer 2 on the yamaha receiver.... ... show more

    • Cheap
Was ok while it worked , was gonna order another one to see if maybe mine was just a defect but the price went up over night. So zero stars for that. Avoid this at all cost . Or you’ll be stuck with an expensive paper weight .

    • This thing is a beast, paired with Dayton audio bass shaker 300watts
This amplifier is amazing and works right off the bat with no issues. 4 stars because there’s NO FUSE. If your speaker wires happen to disconnect and touch each other or a ground then poof there goes your amplifier.. becareful!

I was blown away by how much bass this little guy puts out. I got this to use in my back yard. I am using a Pyle mini amp for the spa outdoor speakers. They sounded decent but I needed some more low end. I had an old Kicker L7 sub laying around. I decided to hook that to it and this little amp drives it great. I am blown away. ... show more

    • Ok got this amp to push a car sub
Originally I want to use my JL 12tw1 at 2ohm. I tested sub in the ported box it came with. An it worked great no issues the sub hit hard and was moving. Sooooo I also have a JL 12w7 which is rated at 3ohm just sitting in my closet. Pulled it out hooked it up in the corner and it also works. Hitting stupid hard for the vol I'm putting to it. I'm using this with a set of kef Meta3s for my desk setup. So far I'm enjoying the added bass from the amp and sub. Definitely over kill but I like bass a lot. ... show more

    • Kills the Nobsound for Sim Racing applications
Given some specific words used between amps it can be tough to actually know if something will work for your given application.... I'm a car guy, not a computer guy, I do pretty well but when Nobsound says their card has a built in soundcard - I thought I needed to find another amp that specifically said the same thing to fulfill my needs. After reading a few reviews I decided to try this amp as an upgrade over the Nobsound amp, and really all I can say is that they truly dont compare to each other at all. This amp works in every aspect the Nobsound did for my sim racing needs via bluetooth and pushing 1 Dayton BST1 - but does so at half the volume level or less of the old amp with the gain at the lowest setting. This thing is for real and now I need a bigger sub for the low frequency effects on my racing rig. ... show more
