So I have a 93 SHO w/ Premium sound and I think it sounds like crap so I pulled the JBL sound out of my parts car (92 SHO) and went to install it. First I put in the four main speakers, then installed the sub, then I took out the premium amp and put in the two JBLs and the little black box w/ the red sticker on it. After all that I started hooking up all of the connections starting with the one going to the black amp, then the one going from the black amp to the silver amp, then hooked up the wires from the black box. The only problem I had is the yellow and black wire coming off of the black box had a different connection then what the connection that went to the corner of the trunk so I spliced some wires so I "think" that should work. After everything was hooked up the radio lights up but no sound... So it makes me wonder if the black amp isn't shot, or my wire job on the one connection didn't work. Either way, I'm loosing gas milage cause I have no music so I'm always making my motor make up for the sound! Well if anyone knows what is going on I would be a happy man! Thanks
