I've been thinking about making my own Front speakers with some Car audio gear I have left over. I was looking at a 4 way setup/ or really a 3 way with sub attached. I will be makeing my own boxes. Most likely using some Pro Amps, in the 500 - 1000 watt range to power them. And they will be tri or bi amped. Most likely 1000 watts to two JBL GTi 15's in the base, and then 500-800 watts to the 6.5" and 1" tweeter from the GTI608 set ups I have. I'm looking for a 8" or 10" midbass for the setup though. I think I'll run the 6.5 with the tweet using the crossover that came with them. The 8/10" mid will be getting about 800 watts to it and the all the speakers will be in thier recomended space. Is there any chance this can work out nicely?
