Ok, I have an alpine pdx f6 4 ch, and i'm looking to bridge the amp. Right now, I have the front ch running my components, and the rear powering a small sub. But I would like a little more on the sub ch. Possibly more on the components. I looked at the manual and it says I need y splitters to bridge it. But when I asked alpine to explain this process better, they messed it up even worse. So here I am. Do I need 1 male/2 female splitters or vice versa? How would I plus them in to get the sound I would like?
