Hello to everyone NEW to this forum. Ok to the point. i a have 2 amplifiers one for subs and a four channel for mids and highs 50 X4 @ 4ohms now i dont think i got enough power going to my front speakers so i want to get a 2 channel amp for the fronts and run the 4 channel for rear and tweeters? 2 amps come to mind.(MB Quart PAB 2100),(Phoenix Gold Ryval V1502). So what i am really asking is. Is this a good idea and which of those amps i should get? thanks in advance
