  1. HD 800 watt 4 channel amp

    Bought this amp at Walmart last June for my Geo Tracker and bought there matching 6.5" 3 way coaxial speakers & 5.25 3 ways. It powered all 4 speakers beautify quite loud with little distortion. Then I seen one in a pawn shop for half price $50 offered $30 and got it. Very happy with this product and would like two more to strap them together. Best bang for your buck out there. Only thing is it needs Pre amp RCA out to daisy chain them together

  2. HD 800 watt 4 channel amp

    I bought this amplifier at Walmart and I loved it so much Ive recently bought another one to install under both my seats to power all my full range speakers.
    This amp is quiet surprisingly powerful at 75 Watts per channel at 2 ohms yet it is also very clean sound from the speakers.
    For only a $100 bucks Im very impressed so far time will tell if the 2 amps continue to perform so well I would recommend buying this amp if your on a budget and want fairly high wattage to run your speakers.
