About 3 months ago in my quest for the blend of SQ and output I bought a pair of Hybrid Audio L3-SE's from my local dealer. I told them that I would prefer to have them installed in the factory dash locations of my XC70. The dash has them firing straight up at the windsheild. I have them running active off of a RF 450.4 on the front channels and 6 1/2" Focal slim polyglass off of the rear channel. I do have a 3.sixty.2 in the mix but I haven't go ahold a proper palm to tune it with so it really doesnt do much. Here is my problem I get a annoying ( to me ) amount of ringing or harshness at higher output. Will I need to go to pillars like others have or??? I thought I would be blown away by these and I am not. I'm frustrated but not convinced it's the speakers fault. Help a brotha out.
