  • New company, Great amp, zero complaints
Model: BT700
>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 kit. 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 its rated specs: 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. >I haven't connected the remote bass knob yet. I just use the gain setting on the amp, and the bass EQ on my Kenwood CD head. >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. ... show more

  • Plinius PHF650D clone.
Model: BT700
This amp internally is 99.9999% exactly the same amp as a Plinius PHF650D which was dyno'ed on YouTube. The Plinius PHF650D got over 300 watts RMS @ 4-Ohms Dynamically, over 580 watts RMS @ 2-Ohms Dynamically, and over 925 Watts RMS @ 1-Ohm Dynamically. So this lil beast of an amp will output more than rated power! ... show more

  • Works great. Nice bass
Model: BT700
Small amp with a little weight to it. Seems to be well constructed. Works great for my 2 10in skar subwoofers running 400 watts each. Great price and great sound and power

Model: BT700
for a very budget friendly amp this is the one you need it pushes a thousand watt sub easy and has really good sound quality

  • Works great
Model: BT700
I gave this amp a 4 star cause I'm only running a 10inch magnum subwoofer 400w rms on 2ohms off a dual magnum sub kit and the amp gets a little warm for a just a 10 inch but I'm getting another 10inch so I hope it won't blow or get to to warm or hot I will be buying another if it works good with 2 10s on 1 ohm. This is a very good amp for 46 all I'm saying is just get it if you need a cheap power house ... show more

  • Works Great For The Price.
Model: BT700
Works great for the price. Its not as good a a $100+ amp but my single 10" CT sounds bio Works great with this amp at 2 ohms. It is small and easy to hide and it was very easy to install took about 5 minutes since i already had the wiring. The only downside is the spade connectors, i couldn't find any spade connectors that fit my 8 Gauge Wire. ... show more

  • Is nice
Model: BT700
This is well worth the money and seems to be hanging with a 1ohm load bridged and no noticeable clipping.
