Well I have a plye ya first mistake but it works very well its the triple magnet its discontiuded but any way The 15 inch sub got damaged by mail the pilar moved over on the voice coil ya great had no idea so I pulled the cone out centered the pilar and did my best to recenter. Surprisingly I have a little rub u can only hear it at low volume so my question is The dust cover is broken out and the rubbing is getting it hot on the voice coil and Pilar should I glue a new dust cover on or leave it open for air movement I know that the sub it not going last long but I want to prolong its life If it helps it has 1980 RMS to the sub 140 amps x 14.0 volts= 1980 watts Please let me know what to do thanks
