Have you seen the available space in a tC? There may not be enough room for three 10s ported back there...3 10w3v3's ported. not sealed or 13w7 PORTED not sealed. why sealed?
I would /myself for making 2 threads asking the same question, and then have them bury me in the most expensive casket they can find....even tho it will do just as good as one half the price.
