Aftermarket stereo installed and no sound! silly me.
I picked up an Alpine 9887 off a forum member, got it installed and powered. But I didn't get any sound. I found the audio wires were capped off and not connected to anything. 
I'm hoping to retain the Bose subs. I've been doing some searching and found that the SVHGM4 and SVEN2 from Peripheral will help me do that. Is this correct? I'm a total noob when it comes to wiring. Any advice would be appreciated.
Thanks.
EDIT: forgot to add that the radio is going into an '03 Z.

When I hooked up the unit to test it, the speakers wires were not connected. They were cut and capped off from the original owner. I hadn't known that at the time, but figured it out later when I took the time to figure out which wires were what to diagnose.
The two smaller white connectors that were unplugged from the original radio were not hooked up to anything on the Alpine or harness. The GM harness came with the Alpine from the forum member but some wires were cut and capped (especially the speakers wires, I checked these twice). It also looked like they had spliced most of the wires and I guessed the original owner had used an amp with the Alpine.
But, I figure the GM harness is junk since the subs won't work with it. And, I'd need the parts I listed above to get the subs going, too. I was just wondering if that's a good direction?
Thanks.

IMO stick with what you have and get all the speaker wires conencted between alpine and gm harness ie match the colors, also make sure to to hook up the amp turn on wire from the alpine to the powerantenna wire in the gm harness
NOTE: the blue wire in gm harness called power antenna/amp turn on MUST be connected to the proper wire from ur radio. if your radio has both an ampturn on (remote) and power antenna wire u must use the amp turn on one.
this will get all ur speakers working then all that is left is getting a sven2 for the door subs, the gm4 harness or whatever is garbage and they dont work right half the time u can splice a few wires on the one bose plug and get the door subs working very easily while saving 50 dollars on the harness
you can try wiring without a sven2 for some ppl it work great for others they get noise, see my post towards the end of the c5 faq which shows how to do this with 5 dollars of parts from radioshack, very easy to do

OK, UPS delivered the SVEN2 adapter. I won't get around to installing it until Sunday, but this site has an App guide that I was going to use: http://www.discountcarstereo.com/detail.aspx?ID=1080.
I also found this when searching the forum for troubleshoots: http://forums.corvetteforum.com/audi...8-woofers.html. It all looks better easy. Is there anything I should look out for? Thanks.

OK. I'm trying to hook up the SVEN2. I connected the harness and radio speakers wires to the inputs and outputs of the SVEN2. Now, I have no sound from the fronts and subs are not doing anything either. Should I have connected the speakers wires directly into the SVEN2? Do the bose subs have their own wires?
Thanks.
Thanks.

sorry thought i posted everything already
read this should explain
We now need to wire up the Peripheral SVEN2 for the bose subs. We will not use the set of wires with the rca’s. Set the input switch to wired, and the output switch to RCA. Leave the gain ***** at the max position, they can later be dialed down during testing if the factory bose subs are too powerful. On the input harness match the wires to the same wires from the radio and gm harness, white and grey (discard the black wire). Now the output side will be wired into the bose subs harness. Of the two remaining harness we have from the OEM headunit we will use the larger one. From the SVEN2 output harness take the grey/black and white/black wire and splice them into the light blue wire. Take the grey wire and connect it to tan/black, connect the white wire to light green/black.
dont forget to tie blue wire from gm harness to amp turn on wire from ur radio

Thanks. I just got done wiring it all up. It turned out perfect and I'm pretty happy now.
