My alt is factory 110... if I thought an aftermarket unit would be SOMEWHAT reliable, Id grab a 250 and go bigtime. But I dont dip below 12 volt flat with my amps and settings now, so Im kinda happy
My a/c also stopped working, when I get it checked out, if it turns out the compressor went bad, Ill be puting an alt in its place and grabbing 4 HDC3's and throwing them in the same box with another 4000xd
