I have an audiobahn aex300 30 band eq with a crossover built into it. My system sounds great without it but when I hook it up I get this wierd almost feedback type sound through all my speakers. Sometimes it will start out fine and then the sound will just fade out and get really distorted and fuzzy sounding. It is grounded out of a dist block along with the amps and the amps have no problems. I think it is an internal problem but I was wondering if anyone else has had similar problems.

I kinda solved the problem by ordering a set of EQT's but I would like to get this thing working for my wifes car. Thanks for any input.
