I would do it myself, but I am OCD when it comes to my electrical. I cannot stand voltage drop and make sure that I have more than enough battery power to back up whatever I want to do. Running an amp below 1 ohm puts alot more strain on your electrical system.
disclaimer:
ALSO, this is the most important part. YOU WILL NOT have warranty for issues caused by running below 1 ohm. If you fry the board due to anything stemming from being wired below 1 ohm, that repair bill is on you. I just want to make sure that is perfectly clear before anyone does this.
I run my amps at .5ohm and if something happens to them, I wont be calling to Rusty crying expecting him to fix them. I take responsibility for myself and my decision to run below 1 ohm.
