I have a 4 channel alpine amp 45x4 that I gonig to install for my bostons pro series 5.5. If I were to bridge my 4 channel amp to down to 2 channels will that bring it down to 1.5 ohms if my speakers are 3ohm nomial or will would be lower? I don't know if the alpine amp can handle 1.5 ohms or can it? Btw.. I am going to run the rear speakers thru the deck. I want more power going to the bostons. Thanks
