You can't beat this amp for the price. It works flawlessly and drives my 10" sub better than I ever expected. The bass knob is metal and smooth. Just quality all the way around in my opinion. I am running a 10" Sub in a down firing box with a slotted vent under the driver seat in my CJ5. And it pounds . It super clean and clear as well as very loud. Anyone with a classic Jeep CJ knows the difficulty in getting a system to sound good in one. This sub is a excellent addition to the answer of that question. It's fantastic, runs cooler than I expected. It's a classic old school 80s - 90s appearance but don't let that fool you. It has all the correct controls and input features needed to perfect the output and sound. It's stable down to 1 ohm and compatible with modern audio systems. It's never got hot or sent in to protect mode while I have been using it. And I've been working it hard daily. It's a awesome buy

Purchases 2 to sell and test in customer's vehicle's but honestly when I saw dual 40amp fuses which basically tells me amp can do close to or rms rated. I was blown away with the 1st install wired at 2ohms with 8 gauge amp kit and a android aftermarket radio. Bass knob works great with sound level difference of each rotation also wasn't a cheap plastic but a metal casing bass knob. Small compact class D which stayed cool during testing and basic tuning after install. Amp as a nice weight to it heavier than it looks and so cheap of a price. Highly recommend and will buy to sell and promote more. Especially after sold and installed for the 2nd customer which constantly changes his setup but instantly no complaints of this amp. Power is true rated or close to in my opinion (no dyno equipment) plenty of controls for fine tuning and very easy to use

Have this powering 1 Skar 8 EVL. Was disappointed at first, it killed off my alternator, that was already at almost 200k miles of usage. Was about to return the product until I gave it another shot with a new alternator, for 56$ this is an ultimate value amp, I really pushes the EVL, you'd think I had a bigger sub, it doesn't get too hot and it has not cut off on me while playing heavy bass songs. Highly recommend this if you want something cheap but that has decent power.

>Great RMS watts per dollar value >Silent turn on/off, no thumps or pops >No problems with hum, buzz or alternator whine. >Honest / conservatively rated by the manufacturer. There are no BS "MAX-Power" specs anywhere in the product. Best Balance should be commended for that. This reminds me of the late 80s and really high end ($$$) manufacturers like Hifonics, Orion, MTX, Rockford, PPI, Linear Power (etc) would rate wattage at 11.5 Volts, to simulate a worst case vehicle electrical system (old tired alternator / battery). >This amp is a re-brand of the plinius PHF650D, the circuit boards are the same. So this amp should come close or even exceed its rated RMS: 220@4, 380@2 and 700@1. (The Plinius was bench tested on YT at 290@4 ohms, 500@2 ohms and 750@1 ohm). >I am only running a 4 ohm load in a SQ music listening system, with an infinite baffle 8" sub. I am not SPL burping or playing tones. Sounds great so far with music, although admittedly I don't have anything to base-line it against. >It is heavier than I was expecting. So it should stay nice and cool, with my 4 ohm load. At 4 ohms it only draws ~28A. >The only thing I can nit-pick about are the old fashioned spade terminal lugs. But honestly, once you get them connected its a moot-point. I went the extra mile with flux & solder for the 4AWG power and ground lugs. For the speaker and remote turn on wires I just crimped them. >I think Best Balance is kind of new, hopefully in the future they will offer more conservatively rated amps in their product line. This is a great way to start out. I hope they do well in this business. [EDIT 4/27] >After almost month this amp is rock solid and my impressions above remain. Zero complaints. >If you are in the market for an amp and are confused by "MAX-POWER" ratings just ignore them... they are marketing BS. Instead use fuse ratings to get a realistic wattage range. This map has 40A+40A = 80A total. 12.5V x 80A = 1000W. No amp is 100% efficient. A typical class D like this one is 80%~90% efficient. 85% x 1000W = 850W. This is just a ballpark estimate though, and it does not take into account impedance loading dynamics. As I mention in my review this amp is conservatively rated, and Best Balance specs it at 700W which falls in line with the fuse math. >I finally got around to connecting and mounting the remote gain control. Its basically an attenuator pot in line with the main gain pot on the amp. It is NOT a bass "EQ boost". So whatever gain level you set on the amp, the remote knob will attenuate from that baseline. For a while I had the remote knob set to MAX, and adjusted the gain on the amp. In that scenario the remote knob can only attenuate (turn down). I wasn't happy with that so I set the gain on the amp to MAX, and then adjust the remote knob to taste. Usually it remains around 12~1:00, but some songs the bass is too heavy so I reduce it. This for me is more flexible, but I have to be careful not to push it into clipping. >I really don't use the high pass / subsonic filter so I have it set to its lowest frequency. My music collection has no musical content below ~35 Hz anyways. >I have my low pass filter set to around ~100 Hz, but I can't really tell. There are no frequency markings around the dial. So its kind of guess work at best. You need a basic RTA and pink noise to set it right.

The amp is solid. I bought it suspecting it was a clone of the Plinius 650 and after cracking it open was correct. It was 46 bucks when I bought it, which is just an insane value, now that they've raised the price though, I'd go for the Plinius 700 or 1000 for the clip light and smaller size. This amp isn't as efficient with its board space as the new Plinius's are. I have the 1000 and its smaller than this one is. The crossovers have nice features. High and low pass, signal polarity inversion, bass boost, not that I would touch that, and pass through RCA. I'm personally a fan of spade connectors for a lower powered amp, and they are done brilliantly here with a guard that covers all the terminals. The bass knob is very lacking. I'd recommend an after market RCA knob over this one. In conclusion it gets 5 stars at 46 dollars and 4 at 56.

Not sure why listing says Dbasso? Amp has "Best Balance" printed on top, though its not a name, I'd choose for a car audio manufacturer, Im guessing it kind of translated over its Chinese name? Im quite certain its certainly the best amp available here on Amazon in its price range. It hits harder than my Rockford 300-1 at 2 ohms. I actually had to add a battery it was sucking up my voltage on my stock battery/alternator leaving me to call AAA for a couple jump starts recently. Added the big 3 upgrade on 2 gauge OFC 3 along with the Mighty Max V600 AGM cell and we're holding 13.8-14V even at stop lights. My RF300-1 never drained my battery like this amp does so thats my evidence of it putting out more. Do wish the remote knob had clipping lights on it but for its price you cant really ask too much. RF usually under claim their numbers so indeed this amp is a cheap monster, plus its like 1/5 of the price I paid for the RF 10+ years ago. I can still flip the RF to compensate for this amps cost and have roughly $75-100 extra I didn't have before. I suppose this helps cover the big 3 upgrade I did.. Didn't realize 30ft of 2 Gauge OFC costs as much as it does?! If youre interested in it Best better pick it up before they hike the price up as they do with everything they can get away with these days..

If this cost $200 I wouldn’t give it 5 stars. I don’t know anything about this company but I’m pretty sure the price will increase in time . For what the price is right now you can not beat it. What I really like about the speaker output is it has two speaker outputs. So you can have A DVC at 2ohms and you can run it at 1,2 or 4 ohms. I would like to see this put on a dyno . I don’t think it’s pushing 700 watts. I think maybe around 450 watts. Which is still good for the $ I don’t like the terminals but the rest of material and build quality is solid. Looks like they cut costs where possible. Simple plain box and I couldn’t believe it even comes with a remote bass knob. I would like to put two of these on something like a skar EVL or something that can handle around 1500watts RMS. It’s not as clean as my monoblock alpines but I’m very pleased and definitely recommend. If you have 1 or 2 monoblocks running your setup I recommend to get one of these to put on your shelf for a backup if one goes down. I haven’t pushed it hard yet so I can’t say if it heats or not.

Great little amp for the price. Easy to tune and puts out a little more power than it's rated. Doesn't get hot at all in this 116 degree heat here in Texas. Only downside was the power and ground slots being a tad bit small but overall for the price this amp is extremely under rated. A month in with no issues would buy again without hesitation
