Hi, I have been wanting to install an all new stereo in my '94 3000GT. I have been doing a lot of research and think I have settled on all the main components. They are as follows.
Infinity Kappa 693.9i 3-way 6x9's
Infinity Kappa 609cs Component 6.5x6.75
Rockford Fosgate P3D212 12" sub
Pioneer GM-D8604 Amp
Pioneer GM- D8601 Amp
Here are the specs.
693.9i's - 110RMS/330Peak, 96dB, 2Ohm, 3-1/4" mounting depth
609cs - 90RMS/270Peak, 95dB, 2Ohm, 2-7/16" mounting depth
P3D212 - 600RMS/1200Peak, 85dB, 2+2Ohm
D8604 - 150wx4 channels @ 2Ohm
D8601 - 800w @ 1Ohm (wiring DVC sub for 1Ohm resistance)
So with that out of the way, I'm not sure what parts I need for the actual installation. I found a few dual amp kits on Crutchfield, but I'm worried they won't be able to handle the amount of power I need. What gauge wire should I use for the power cable, ground cables, and speaker wires? What about wire for the sub? Also, what amp fuse should I use? The 8601 has 2x 40A fuses and the 8604 has an 80A fuse. Going by this, would a 175A fuse on the power cable work? Should I put the fuse before or after the distribution block? Lastly, will I need a HO alternator? I don't plan on running my system at 100% pretty much ever, the loudest I'll go will be maybe 70 or 75%. My car has a relatively new alternator, and I believe the OEM alt is rated for 90A.
Thanks for any help, I've done a whole lot of research and these are really the only questions I still have. I think I understand the installation process itself, once I get all the parts I need it shouldn't be too hard.
