Anybody out there who could make some suggestions would be great. My kenwood head unit only has two RCA outputs. I have all four of my new speakers hooked up to a 600W 4-channel kenwood amp, those speakers use up the two RCA outputs. Fortunately my 4-channel amp has an extra RCA output, and i have my other 600W 2- channel amp for my sub connected to it. I have one 12w3 JL sub hooked up to that. The one problem is that whenever i turn up the bass and volume for my sub, the bass is turned up in my speakers as well, and it sounds horrible becuz there is too much bass going to the 2-way speakers. Im trying to avoid buying a new head unit, and im wondering if there is any way that i can crank up the bass in my sub, but turn all the bass down in my speakers at the same time.
