please help asap i am trying to get this installed tonite.
thanks

is there a diagram for the metra 70-1857? just so i can see where everything goes. there are 3 grounds on the metra harness. do they just tap together with the hu ground? or should they go to a screw or something
thats normal
because of the relay box behind the rear seat, when you change stations or sources, the amps turn off and then back on... stupid yes but you have no other option, less you rewire and replace everything....
ok i got it installed but that popping noise is really annoying when i change tracks, stations anything. there has to be a fix for this b/c i know there are alot of people using the factory amps.
sadly no
only thing i can THINK of is attempting to run your own constant wire to each of the mini amps, like a remote wire is on aftermarket amps, put a switch inline, and make sure to shut it off when you shut your car down
Did you finish your install? I am going through the exact same thing right now!!!!! 93 seville delco gold series I did solve the radio plays but no cd sound though... Are you using the rca jacks that came with the harness? If so you should then have your power wires hooked to the Hu harness.. i.e. ant. blue, yellow permanent power and red 12v. anyway.. I hooked mine in the trunk first before removing seats. And I found that when you switch to cd the antenna goes back down. On my sony HU this causes the rca outputs to cut out even though I can see on the faceplate that the cd is playing. The solution is to change the antenna wire to the Amp wire on you HU this sends perm. power to the antenna while the unit is on and the cd sound comes through.AND COMES THROUGH NICE! I have the same popping problem Have you solved it yet? Thanks Joe
The second one actually has the step-by-step details that I used to make mine work, although I did NOT have the Bose amps - just the Head Unit, so I decided to run my own speaker wire. If your system is Bose all around, then the Metra harness will work out of the box. Follow the advice to get ground loop isolators, and install as part of the upgrade. Almost a certainty that you'd be back opening up the console to install these later.
It's really not that difficult to do this. I found that there was plenty of room on the passenger side of the car to run this harness, and there was enough length on the wires.
