  • Great sound

    Posted by anthony fleetwood on 29th Mar 2021

    Great sounding amplifier I have 2 channels powering tweeters and 2 channels powering woofers the crossover selection is great for band passing the woofers and the amp looks well built

  • Impressive!

    When my Alpine MRV-F545 decided that it wanted to start acting a fool I decided to buy a new amp. I am very impressed with Barbara Ann. I feel like the 4 x 100w rating is conservative. Output is on par with my Alpine however the US Acoustics seems warmer sounding... less "treble..e?" Ah... it sounds more full than the Alpine is the best I can explain it. WELL worth the price and then some. Great amp, no regrets and I will be getting "Mike". I would call this a quality budget gem. Running this to Kenwood eXcelon XR1700P components and it's smooth.

  • Very nice amp

  • Un-beatable Quality for the price

    Clean,very well built amp. Looks nice too. Can't beat the price. I will be purchasing the "Big Ben" amp in the near future. US Acoustics FTW

    I have the Barbara Ann powering my front two way components and 6.5 ssa evil mid range in the rear doors and it gets loud while maintaining a crisp and clear sound. Definitely will buy again
