Before I begin, yes a search was done...........

Ok, I have the Tripower 52mm center speaker gauge holder, but I have decided to go with 60mm gauges.
Everything I have read says to drumel out the plastic to make them fit, but I dont want to do that incase they don't fit in depth!
What are my other options? I dont care if its center chanel or A-Pilar, I just need 60mm holders.

 

measure the depth of the pod and then the gauge and bam!!! There's your answer. And Dremel is a good idea if there is enough material.

 

Does anyone know if i can buy 60mm holders in either the center chanel or A-pillar?
This way I wont ruin the 52mm and I can sell it to someone that may need it.

 

I don't think that for the center mounts there is enough material to enlarge. You can get a 60mm pod from here though: http://hometown.aol.com/flyrx7/Rx7-Gauge-Pod.html
