I have a US Amps Merlin D2 (MD2D). They are rated as follows: 635@4ohms @14.4 1030@2ohms@14.4 1521@1ohm@14.4 These amps are very nice amps with clean power, you can do a search and read the reviews to see this. I bought it from a dealer and I have the receipt for it and I never ended up using it so it just sits in its box in my closet. It was used in the dealers demo/show vehicle and it looks brand new. I have the original packaging, manual, remote bass control, and everything. $350 shipped. I have 112 feedback on ebay. My name is StrictlyCustom.
