Deciding on a setup at this time will includes 6.5 rainbow SLC up front and 1 12" AA arsenal sub. Should i get a 4ch amp and bridged the rear 2 ch to sub or 2 separate amps, like a 2 ch and monoblock? I was almost decide on an alpine MRV-f545, but reading through the post, seem like I can do better for the money. budget is around $350 for the amp or amp(s).
