I'm all-ears
I don't remember exact box specs, it was so long ago. I don't think my sigs on the forums is accurate after I increased port length and decreased port area.
My electrical system is solid. I have four alternators. Two stock 125 amp ones, a Singer 370 amp large case, and a Singer 320 amp small case. I've got a battery up front and five batteries in the back for my battery bank. Voltage is solid. I also have a 300 amp Excessive Amperage alternator coming that will get here on Friday. Voltage doesn't drop below 13.7 at idle going full tilt, and is usually in the high 14's
Also, I've got Sky high 2/0 OFC wire that is as big as 4/0 welding cable. I'll be adding more runs of 2/0 welding cable after it gets here
