Been a while since I have updated this. So, I will continue where I left off. I have changed the 3 JBL GTO 15" subs to PowerBass Xtreme subs. Dual 1 ohm voice coils. Pretty wicked. I have them wired series/parallel to a 1.5 ohm load. I also removed my Orion 250 HCCA and replaced it with an Orion 2100 HCCA. Also had to upgrade the wiring to handle the load.
