The best thing to do is bring it to your local car audio shop. It should be relatively inexpensive and you won't have to stress. ALSO, look online for the shops... Do some research if you'd like to make sure they are honest and have great customer relationships...

make sure remote wire is good and tight, also make sure the ground has a solid connection.

If this helps please leave me a rating, thanks.

yeah thats fine

but to be honest it would be better to look in the back of the radio for rca jacks

but you can tap into the rear speakers wires

also connect the negative of the amp to a metal point on the car, not the negative of the battery

and the positive of the amp to the positive of the

also you need to find a remote wire (this is usually behind the radio)
so im guessing you will have to take out the radio
unless you add a switch from the postive of the battery to the remote jack of the amp
and manually turn on and off the amp while driving the car

but this runs the risk of leaving the amp on and draining the battery

so i suggest taking out the radio and using the wires behind it

sounds like either a bad earth or a bad remote signal.

check the earth cable for continuity - make sure that it has a good earth to the chassis of the car.

also check the remote signal cable that runs from the back of the head unit to the amp ~(use multi meter to check continuity).

I have never heard of a display for an amp error on a car stereo, and I worked for Pioneer. Barring that, you can try to reset it(shown maybe in your owner's manual). If you are interested in a repair, please contact me on my website at audioserviceclinic.com. Thank you.

Do you mean the System cable? https://www.manualslib.com/manual/712344/Pioneer-Xc-Is21md.html?page=6#manual

Unfortunately, Pioneer does not seem to have this cable available any more. http://parts.pioneerelectronics.com/model.asp?modelNum=XCIS21T . The only replacement part that I can find is a lens for the CD player.

I wish that I had better news for you. If you got the XC-IS21T used, check with the seller.

You require a laser assembly. As they have not been produced for 20 years, depending on the model number, there will only be copies on fleabay as NOS lasers are not reliable.
