Ok me and every stereo guy I know is lost on this one
I installed the infinity 7540a amp to my alpine CDA-9853 head unit. When my truck is running the amp cuts out from a split second to a few seconds depending how how loud the stereo is. When my truck is just on but not running it does GREAT. I have checked the ohms at all the speakers and they are correct.
power is 12.3 v with out the alt and 14.4 with the alternator at the amp power connector.
Someone told me to try to upgrade the power system so I took all the stock 8gauge wire out and replaced it with 1/0. Still nothing.
I have called and checked to make sure that the Head unit is not putting out too much current for the amp and they place I purchased it from told me that they should be fine together.
I have 4gauge power and ground wire at 0 ohms on the amp.
whats getting everyone is that its fine when my altenator and motor are not running.....
From what you describe it could be that its not getting enough power when the car is fully running. Its been a long time since I have had to deal with car audio problems. Does it happen when the vehicle is running but in park? If so it could be a short (Not likely though, it would be happening more often). Or it could be a loose connection somewhere that the vibrations of the vehicle are shaking. That would also be a problem if it happens when it moves. If it is still a problem, I would take it to a Checkers Auto. A lot of them offer free electrical testing.

Peripheral stereo mini plug cable (3 foot cable, male to male miniplug). around $20 Monster portable music player cable (stereo mini-to-RCA adaptor) around $20 Arista stereo mini-to-RCA adaptor (6 foot cable with mini and dual RCA plugs) around $5 Hope that helps.
1. Go to menu
2. Using touchbar go to 2nd function
3. Using touchbar choose a preset colour or tap P1 at the end on the touchbar and use the volume round thingy to choose your own colour by turning the volume knob.
I have an Alpine CDA-9813 and to access bass, treble, fade, and balance, you need to press the volume button. This button is usually rotated to adjust the volume but on mine, if you press it in, first time accesses bass, second press accesses treble, 3rd press accesses balance(left to right), and 4th press accesses fading (forward to rear. Press it a 5th time and it either brings you back to volume or back to the main screen. I think it is volume tho. I would assume that the 9853 would work very similar, if not the same.
Its probably your wiring harness that came with the stereo. Which can cause many more problems. alpine changed their wiring harness around that time. But they used the same plug, just wired different. So now there are crossed wires, but the plug fits, causing the amp chip to fry. maybe even further than the amp chip. an amp chip replacement runs about 80$ at a repair shop. if its just that.
I could not find an owners manual for the CDA-9853, but I did find one close to it and it should be able to guide you to where the bass and treble levels are It is the CDA-9820. here is where you can download it from for free: http://www.alpine-usa.com/images/products/product_downloads_pdf/cda-9820xm_ptg.pdf
