alright, so i have had 2 10's underneath my seat for some time now, at least 5-6 months and they have been playing perfect. they are powered by a mono channel audiobahn 1300 watt flame series amplifier, the subs are high end audiobahn's. well the other day i was listening to the stereo, it was at a high volume level then all of a sudden the subs go berzerk, they just start going crazy even with the volume turned all the way down. they were stuck on at full volume and wouldnt shut off. i finally disconnected them and they stopped. now everytime when i hook them up they make noise with the volume all the way down, but hit to music when the trucks off. but the noise gets even louder when the truck is running but then it dont hit to the music, its almost like they are playing to the idle of the truck. do any of ya know what could cause this? i was messing with it today, tried relocating and shortening the ground on the amp and it still does it. the amp is high end and it has all built in features like crossover etc...so iam clueless on what it is. its just weird that it played perfectly normal until that one day when i had the stereo up loud. and it cant be the subs because i tried another set of 10's and it still did it. thanks for anyones help. -Ryan
