stable at .5ohm and 1ohm bridge. I did 1ohm with 2 18's all day. Granted I had to run the car to power it.

None. Maybe, if anything, it is large and bulky.

I bought this amp back in 1999. Put in a 1987 Lincoln Town Car w/ 4 Super Pros 12". Amp Rocked them. Moved up to 2 MA Audio 18" ported. I won Three Competitions with this setup. I bought a second UL300HC and I started Blowing my MA Audio 18". Amps were clean sounding and full of power. Stayed cool. I messed up my new amp by crossing my wires while amp was on. Cried. But the 1st amp I still have and is very dependable. Spend the money and hook it up correctly Lower the OHMS and HAVE A BLAST!!!!
