bokeson Posted August 4, 2011 Report Share Posted August 4, 2011 my guess would be distortion caused by an amp putting out a clipped signal. Link to comment Share on other sites More sharing options...

Mazda91 Posted August 4, 2011 Author Report Share Posted August 4, 2011 it's sealed its a pos it feels like it's falling apart these subs and amp are also really old like 5-6 years maybe i just need to know how to fix it before my brother finds out. he has a memphis 2 channel line driver that he got for an extra bass boost i doubt a i blew the subs but i may have. i have bad luck with memphis products Link to comment Share on other sites More sharing options...
canderton01 Posted August 4, 2011 Report Share Posted August 4, 2011 lol there are so many things that could have gone wrong in this situation. Is the gain on the amp cranked? Is bass boost on the amp turned up? You need to ditch the line driver all together, or at least tell your bro that. Do the subs still play? They may just be slowly dying because you're clipping them to hell. 2002 Camry XLE 35% tints all around 17'' Enkei FD-05 rims Fi Q15 in 3.8cu ft box tuned to 32Hz Pioneer DEH-P7200HD AudioQue AQ1200d 4 Gauge Tsunami wiring/RCA's mids/highs - OEM JBL system AudioTechnix Deadner Big 3 upgrade My YouTube Link to comment Share on other sites More sharing options...

Skullz Posted August 4, 2011 Report Share Posted August 4, 2011 If every sub is making the noise then it's going to be from the amp,rca patch cord's or h/u, possible something in the amp went and is giving you a heads up before causing more problems. Do you have something to else to hookup as far as extra sub or an amp to see if that may be the problem, diagnosing does require having some good known working equipment so when you hook something up you can then begin to eliminate each piece as you move down the line checking. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...
Mazda91 Posted August 4, 2011 Author Report Share Posted August 4, 2011 the box is made out of some cheep wood it's carpeted and i don't feel like taking the carpet off but at some places it's slowing turning into dust and can be be rubbed off. the subs still play good. now that someone mentioned it i remember my RE used to do that and i needed new RCA cables so i may try that but he got his line driver because he couldn't stand the fact that my 1 15 beat his 4 12s lol i didn't set the gain on the amp or line driver so i have no idea to be honest Link to comment Share on other sites More sharing options...
