I recently bought an Amp from Visonik The 1800watt amp from them that didn't last 2 months The Gain & Bass Control shorted Out!! So i call Costumer service and hears the lowdown, First you have to Fax the receipt! Then you package up the amp, Ship to them your Cost, Third they want you to send in your package a 15 dollar money order for Shipment back to you for there Messed up crap! Total cost for you 35 dollars and some change just because you were dumb enough to buy their Sh*# don't buy Visonik its going to cost ya!!!
