yes yes i know i have a wtb thread for a 4 channel alpine amp. i ended up buying 5 channel alpine amp from ebay. its on its way now. i have this 4 channel alpine amp mrv f250. it sounds really clean. only weird thing about it is it has to be grounded to the chassy of the amp. not the ground port. other than that it seems to be okay. im asking 60 plus shipping. its a good amp for the price.
