Technical Q for the geniuses
ok, i'll give the whole rundown, cause if i just ask my question, you'll wonder what the heck for.
I have a 92 Park Avenue. Has the Delco system and is advertised as "Concert Sound II". I have installed my complete system- which the components are listed in my sig. All of the aftermarket stuff is in addition to the factory. I did not remove any factory stuff- built a console that holds the source stuff, kick panels...
My "rear" speakers for my system are the Alpine 6.5'* in small boxes in the trunk for tailgating, etc. They are normally off- only on when the trunk is open. i have wires that go from the amp to a switch box- Here i have split the wires so that i can run only the front stage speakers, or turn them off, and turn on the rears, or turn them all on. Its a small box with a switch in the Positive for each speaker. If you're following me, this means, that when i have one pair on, the amp is at 4ohm, if all four speakers, then 2ohm per channel.
OOOOK. I decided to try to run the rear factory 6x9s with the rear speaker leads from the amp. I figured if the Delco system is off, and i put power to those speakers, they would play with the aftermarket system. They did, but very strangly- apparantly there is a common negative or something- when one was hooked up, the other only needed one wire to work, but it wasn't playing stereo... it was goofy, so i decided to forget about it, and unhooked what i had done- i only T-Tapped into the lines- never cut. I went to turn on the Delco system again and no sound comes out at all- none of the speakers. the radio is on- display says it should be playing, but its not. no fuses blown in the main panel, no fuses at all behind the factory deck...??? What is malfunctioning?? Anybody know what i did to the factory system? did i overload the circuit board inside the deck??
Thanks for any help, sorry for the novel...
