Currently running a decent alpine one. alpine ute-42bt
It only have 2 sets of preouts @ 2v each. Currently I'm using y splitters to run my 4 channel off the "front" preouts and my sub amp is going off the "rear/sub" preouts.
Is it worth upgrading to something that has 3 preouts (front,rear,sub) and is at 4V? Will I even notice a difference? Maybe something like this: http://www.futureshop.ca/en-ca/produ...4a643fd3ffen02
