troubleshooting cda-5755g

I put a alpine tda7563 with cd addon cda5755g, amp subs and 4 speakers. before i installed the cd addon, tape and radio works fine, but when i pluged in cd addon, the radio/tape output volume does not work, but when i put cd in a cd addon, volume works fine. what did i do wrong?

hmmm, a technical guestion, well are you sure that the tda7563 is in fact the correct part? Is it the exact one that came out? If not, get the one that came out, these arent interchangeable (for the most part), and make sure that there are no solder joints where there shouldnt be. I dont know what else to tell you. Good luck. If all else fails, unsolder it, take it out, clean up the open spots with desolder wick, and solder it right back in.

the cda-5755g is a cd addon, i already installed like whatever is on the manual, but somehow sound of the radio and tape from tda-7563 does not come out right. i use ai-net connection just like what they told me, but somehow came out wrong. cd and tape came out 1 volume, and none of them come from the amp.

Now I'm having problems with my tape player, after i unplug connector from the cd addon, the control volume stop working, it can rotate volume level but sound that come out does change. Could this be my volume control from my tape player? why when i play cd in a cd addon volume control start to work?

there are so many possablilities, its too hard to say without it being right here for me to see, sorry, I'd just go out and buy a new cd deck.
