New poll - Interested in powder-coated speaker brackets?

I think I will order one. I have to look into speakers first. I have a 10" sub and two 6X9 boxes behind the seat. I am driving it all with a Polk Audio 2200w five channel amp. I need to find some 3.5 speakers that can take some juice. Have there been any issues with the wiper linkage hitting the magnets?
