Unless other specified in paperwork, all Alpine receivers are 4ohm capable only.
Now yes there are exceptions, but not many.
Now for amp almost all alpine amps can be run in several different resistances.
Basically for sure 4ohm, now depending on model some have abilities to go as low as 1ohm stable. But for most 2 ch alpine non special amps are all 4ohm and most 2ohm capable.
Now better models can do things such as run 2,3,4 ch. And some can even get to .5 ohm loads stable.

What button should I push if I don't have an "auto" button, both on the remote or the head unit? I have a dNx-5140. All help would be appreciated.

There is a disc stuck inside unit, something probably is jammed up with mechanism. Going to need a professional or good tinkerer to take apart n look inside.

Do you have an external amp? Give me more info on stereo going in, and what it does do.

Step 1 Turn the device off, wait a few seconds, and then turn it back on again. This process will clear out any software errors that are causing the touchscreen to malfunction. If the touchscreen still doesn't work, remove the device's battery, if possible, wait ten seconds and then put it back in.
Step 2 Remove both the SIM and memory cards from the device, if the device accepts such cards, and then turn the device off and back on again. Sometimes errors in these cards can cause devices to malfunction.
Step 3 Check your device's documentation to see if there is a way to manually recalibrate the screen. This process will either be done through the "Settings" or "Tools" menus, for those devices that have an alternative method of input, or by holding a combination of buttons while you turn the device on, for those devices that only have the touchscreen for input.
Step 4 Upgrade the device's software to the latest version, if possible. Many devices come with software for your computer that will allow you to connect the device and update the software. Often, this process will resolve existing software errors that may be causing the touchscreen to stop responding.
Step 5 Clean the device's contacts and screen using isopropyl alcohol and a small brush. Turn the device off before you clean it.
Step 6 Perform a hard reset as a last resort. This reset will erase everything you have added to the device and return its software and settings to their factory defaults. Even with an unresponsive touchscreen, most devices will have a way to perform this reset either through PC software or by holding a combination of buttons while turning the device on. Consult your device documentation to determine the exact process for performing a hard reset on your device.
Step 7 Contact the manufacturer for your device if the touchscreen is still unresponsive after your troubleshooting attempts. The manufacturer may have additional steps to take that are specific to your device, and if your device is still under warranty you should be able to get a replacement through their customer service division.
Warnings
  • If you have the right tools and are willing to risk voiding your warranty, you can also open the device and scrub down the control board using the small brush and isopropyl alcohol.
  • Many manufacturers offer free telephone support, but some will charge for the service. Check your product documentation before you contact support to know if you will be charged for the service.

Required Items
