Well turned on the car today and speakers started to go pop pop pop in and out really fast. Open the trunk and smells like something fried. So my ppi 2100 looks to be dead. I went to pawn shop and they have a Alpine MRV-T757. Is this a good alpine amp looks older. Just want to run pioneer720prs components. But i want sound quality so will this amp do it. Please help i only have a few hours before the shop closes.
