I have the cda-9815 alpine head unit and installed it myself with the help of a friend. I have been using it for several months now. I just found out that the internal amp requires a direct connection to the battery. (when i installed it, i just got the appropriate wiring harness for my car and crimped the harness to the wires from the 9815 and plugged it in).
1) have I been unknowingly damaging either my speakers (alpine spr-136A components in front, spr-174A coaxials in back) or my head unit by playing it without having the proper battery connection?
2) I intend to immediately fix the discrepancy, and I would like to know what kind of amp wiring kit you guys would reccomend, or if i should just buy the 10 gauge wire and connectors and fuse myself.
3) is there a way to leave the 9815 in place to make this one change or will i have to take out the whole thing and then reinstall it?
