Currently I am running a 4 channel amp bridged to 2-12" subs, using one set of RCA inputs. Now I want to add two 10" subs to the same amp. I will unbridge it and run one speaker per channel. My question: I need to know if I will need to hook up a second set of RCA inputs to do this? Or will the amp split the signal itself? Best way to do this??

listen you best bet is to put a y splitter to the amp off of the main rca wire. its easy quick adn it auto matically splits channel go to either radio shack or local install store what you need is

two wire splitters with one female to to male ends get gold plated.

connect on left to each input on and and do the same for right. but since you running lopass you may not need it

before this read the amp by the rca and stuff check to see if there is a setting for two four and three channels if there is set it on four and there maybe a switch or something that allows the a input control both i am sure the amps has

rcas labeld 1/2

and rca labled 3/4 doing the y splitter is best bet
