So I am planning on building a box for 4 P3's. I am going to wire them down to 1 ohm and power them with a 2400 watt amp. My plan was to get a HO alternator to help stabilize the voltage, but unfortunately it doesn't look like that is an option with my vehicle. Is there any alternatives? My vehicle is a 1999 Trooper and has a 75 or 80 amp alternator that is only about a year old and I already have the big 3 done with 1/0.
