I see Lanzar amplifiers all over the overstock.com they sound good but for that cheap is very sketch.(eg. http://www.overstock.com/Electronics/Lanzar-1600-watt-2-channel-Power-MOSFET-Amplifier/3114746/product.html) i dont know if they are a good trusted brand or not so im a bt hesitant to buy it. anyone with good feedback on their behalf
