DDX470 Restarts When Bass Cranked Up?

[Guest]

I have a 2006 Mazda3 and a Kenwood DDX470 headunit. I also have Infinity 6829CF door speakers in my front doors, with stock speakers in the rear. Lastly, I have a Hifonics Brutus 1600.1D amplifier powering two Kicker CVX 10's at 1,200RMS @ 2Ohms.

My problem is when I crank up my music, car on or off (but more so when the car is off), the radio will sometimes turn off and restart. My radio goes up to 35 on the volume wheel, with 32 being my self set distortion limit. I'm not sure it's really the song that matters, but I can crank up a song with a lot of bass to 32, and after beating away for 10 seconds or sometimes even less, the radio will just restart and then work normally until it restarts again.

To me it seems random. Sometimes it plays the songs fine and one time it would do it every 5 seconds from a heavy bass song, at levels as low as 28.

From the little research I did online I am starting to think it's just being "power starved". Someone said 2 ohm speakers are harder to power, but I'm not sure. My only thought of what to do would be just upgrade the wiring to bigger wire.

If anybody has any thoughts of helpful input, please share it as this greatly annoys me.

It especially sucks when I go to show somebody my system, and the the radio just restarts in front of everybody.

check voltage at headunit when playing.

How would I go about doing that? I don't usually do anything more than crimping and stripping when it comes to electrical stuff.

take out headunit, and take a DMM and read what the voltage is on the 12v from the radio.

check voltage at the headunit as said above..... also check for any loose connections that might be getting rattled free by the bass ect

whoops, double post

Alright, so I get the general idea. You want to break down for me which wires I would be looking for?

I know the DMM has a positive and negative, which prong would go where on the radio/harness?

black on ground wire or ground out

red probe on yellow wire from headunit.

also worth checking all your crimp connections

So just leaving everything connected and check the wires, or unplug the yellow one and test it with the radio on?
