I have a 220 amp alternator to power everything. Also I did a diode modification on the feed (center wire) back to the ecu. It tricks the ecu into raising the alternator charge voltage .6 Volts or so higher due to voltage drop across the diode.
I was looking for replacements for my Alpine speakers that were blown and came across very positive reviews. I didn't need much, so I gave them a try. Definitely good for the price and with the clean sweep they sound very clear and responsive.
Sounds like you guys are into your audio. I've been running a JL audio clean sweep with a 300W 4 channel Crutchfield AMP. I installed CT Sounds Meso 6-5-3 way 500W component speakers. They sound decent for the price. It's good enough for me. Personally I prefer to do performance upgrades over audio.
I brought 15 gallons my from the gas station down the road from me. I was directed to only have a 1/4 tank of 93 and to bring 15 gallons with me. They pumped out the remaining 93 before adding the E.
I'm trying to keep as much torque as possible. I'm at 9.0 compression with +1mm GSC oversized valves. The whole top end is GSC, even the Beehive Springs.
