new to the forum looks like im gonna finally get some solid advice. ok so I have 4 Polk 5x7 MMC570's. I am currently running them with a 200w alpine amp and am ready to upgrade. I've narrowed it down to either the Infinity Reference 7541 or the Rockford Phosgate P4004. I'm an audiophile so I'm looking for accuracy a tight bottom end and detailed mids and highs. Anyone have any opinions?
