Platemail Posted May 18, 2015 Report Share Posted May 18, 2015 I am asking for a friend, he has 2 18" custom built subwoofers, 12 spoke basket, TC9 motors and PSI recones. He has them in a 2:1 4th order blowthru in a single cab F-150. The original Vent holes on the motors were about the size of a dime, but he was advised to boar them out (see the before and after picture attached) He had them professionally reconed, and they set for 3 days and once hooked up they blew (coils unwound and fried) after 2 songs. Could him cutting his vent holes have done the damage? They are on 2 strapped BC2000.1D's @ 1 ohm. The same motors with Shocker softparts played great and he chose to recone them to PSI for better power handling.BeforeAfter Link to comment Share on other sites More sharing options...
Skullz Posted May 18, 2015 Report Share Posted May 18, 2015 No idea on if that was a direct result of his speaker falling apart on the coil, but unless you know what you are doing to a basket, it is best to leave it alone or find a better basket to his liking. There are a few here that would have been better able to suggest what he had done was beneficial or not. 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...
Skullz Posted May 18, 2015 Report Share Posted May 18, 2015 Personally i would set them aside and get a set of new subs with a warranty. 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...
ChevyBoy95 Posted May 18, 2015 Report Share Posted May 18, 2015 Probably clipped the shit out of them so they thermally failed.

Platemail Posted May 18, 2015 Author Report Share Posted May 18, 2015 Probably clipped the shit out of them so they thermally failed. So a clipped signal from less than rated power for about 3 minutes would demolish the spiders and unwind the coils? Link to comment Share on other sites More sharing options...

Platemail Posted May 18, 2015 Author Report Share Posted May 18, 2015 I mean nothing changed on his amps, they aren't clipping for sure. Crescendo installed and set his amps for his previous subs (same motor and basket, different soft parts). That's why I wasn't sure if maybe opening these vents in the basket would have caused them to overheat instantly. Link to comment Share on other sites More sharing options...
