Alpine 9811

Kicker 550.3

ED 6000

Had this set up for bout 3 years now no probs but over the last month when i listen to it at 28 and above the treble get all muffled and u cant hear the highs. When i turn it down to say 20-24 for a min or so the treble returns and all is normal. this happen no matter what source i use Ipod/CD/Tuner and it is hap more freq. Is it the HU/Amp/Mid&high??? or RCA cables???

ED 6000 6.5 set. Is there a way to check the xovers

[lithium 358]

umm idk actually, id start by going over the install, checking wires for corrosion or if a wire came alittle loose, definitely check grounds.

this is all i can think of... im sure someone else will chime in with better ideas... good luck
