Help: My new JVC HU keeps shutting down

I just installed a new JVC HU in my truck last night and thought all was well. I'm getting sound on all speakers... I thought everything was good to go, but this morning when I drove it I found out if I turned it up too much (not a lot just enough to hear clearly over the rain) it would cut out and shut itself down. It was much more sensitive to this with AUX/USB and my Ipod. The radio seemed to handle a bit more volume before it began cutting in and out and shutting off for a second.

It seems to me it's almost like it's shorting out or something?

I grounded this thing to one of the bolts behind the HU.

My one thought is, because I didn't replace the speakers maybe they're shorting out? Or maybe the HU sees they can't handle it and shuts off?

I know the stockers run 2ohms or whatever but I was hoping to run them a month before I could dump some money into speakers...

Any ideas???? Please?

Here's the unit I installed:
JVC KW-XR610 CD receiver at Crutchfield.com

it could be a ground issue. did you install a new ground are is it just grounded via the antenna plug? how did you install the wiring, using an adapter or cutting the wires? 2/4ohm isnt really an issues unless your really cranking it. an aftermarket dack, while not designed to run at 2ohms will run it for a while at normal volumes without any issues. start cranking it though and heat builds up and can cause the radio to either fry or go in to protect mode. usually though it will just fry itself.

there is no ground wire in the 05-08 radio wiring harness. several people have had problems with that when the ground was only going through the antenna wire. pull the dash and find something metal to ground to, make sure its clean(sand down the paint till you have shiny metal).
