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

 

I think your amp is toast. Do you have another amp you can hook to them to test with?

 

Unplug your RCA's at the amp and re-test.... If you still get the crazy noise, time to go shopping.

Possible bad amp, possible wire issue.

 

yea i have another amp to test with, problem is the guage wiring im using doesnt allow it to hook up to this extra amp i got.

 

Since your just testing I would use any old wire like speaker wire to run power to the temporary amp. Twist the temp and permanent wires together and protect with some electrical black tape and see if the subs play normal.

Try what frostby recommended but I doubt you'll see anything wrong with out a variable audio source coming in. I think the sub amp audio transformers are jacked up.

 

audio transformers? so pretty much you think the amp is toast? what was also happening was when i had the everything hooked up and i would touch the speaker terminals on the side of my box where the speaker wire connects the noise would get louder. almost like myself was grounding it.

 

I was thinking the amp was toast but if your touching the terminals on the box maybe the terminal are broken. Hook the amp directly to the subs and not through any speaker box connectors with the same amp and see if the subs still go nuts.

 

i had an alpine 4 channel amp do the same thing, it was toast.
