IMHO, those DPX amplifiers that Crutchfield has on sale are the best bang for the buck. My DPX1851 was a STEAL at $149.99 shipped. If one needs decent 2 ohm mono power for that DPX11551 will be tough to beat for the price.
I also have a DXZ 785USB to install in my fiancee's vehicle, but I am still waiting on her Genesis Profile 16 components to arrive before I get started.
I've had a lot of clarion products, and they are definately under rated. The amps are great for the money, the higher end decks are some of the best sq decks out there, the lower end decks have tons of features, and cost next to nothing.
Clarion Products should be purchased from authorized Clarion dealers ONLY. All purchase of Clarion products, including those made over the internet, from non-authorized Clarion dealers will NOT come with full-factory warranties.
