I think i have a blown voice coil. This is my system: X590 Kenwood Head Unit, MRP-F240 Alpine Amp in bridge mode (100W x 2 RMS 360 x 2 peak) hooked to db 6500 component Polks in my front doors and db 460 in rear pillar running off the head unit only. System started cutting out when balance was set to 0. I can put the balance on the right side and everything is fine. So I swapped speaker outputs on the amp, problem stayed on the left side. Would like to know what would cause this to happen, did I just get a bum speaker? Also, what are my options, can I just buy a replacement speaker?
