imo its both the seller and buyers issue! since this was brought up now alot longer down the road is the problem! this could have and should have been addressed the day he received the ****ing HU! I dont care how well the guy's reputation is im going to test any used equip right when i get it!If it sat on a box on a shelf in a closet and hasnt been abused how did the OP break it? Thats the shippers fault. If he did then it is possible that either one broke it.
