Possibly, idk what power wattage a factory amp is, but most aftermarket amps use a fairly hefty fuse. I would double check all the fuses, engine bay and in the cab. I have see where simple fuses like one for the cig lighter blown caused other things not to work that weren't on the diagram. maybe the circuit that powers the relay for the amp is tied into something else in the cab. GM did some odd stuff over the years!

Alright, pulled fuses starting with the box in the engine bay. Second one, a 30 amp, was blown. Checked stereo, no rear speakers. Checked all other fuses in the engine bay and they were fine.

Started pulling fuses in the box on the side of the dash and fuse #13, a 20 amp, was blown. Check the stereo and I have the rear speakers working. Hooray! I will note that the speaker in the second door on the driver’s side is crackly so it’s blown. There are several, if not all of the speakers that need to be replaced, but I can deal with that over time.

Glad you found it! curiosity has me wondering what that blown fuse was labeled as.

take the old one out and verify if it's a normal speaker or some oddball that GM uses. you can use an ohm meter to check if it's a 2, 4, 8 ohm. if it's a sub, 4 and 8 ohm are available new, its the 2ohm that are a product of GM. they all should be 6.5 inch speaker so the size is normal and easily swapped for something aftermarket.

I installed 3 way kickers in all 4 doors of my truck, but rockford fosgate is the best money can buy. swap them subs out for something that can make the sheet metal vibrate LOL

The AC Delco one I took out was 4 ohm.

In addition to the used AC Delco replacements, I just ordered some JBL GTO 629 speakers, which were very highly rated. I’ve always been a JBL fan.

Got a link for those Fosgate speakers ?
 
So I have the speaker removed from the second DS door. Playing with volume and bass and the speaker on the PS second door crackles badly on bass. So that one is gone. I suspect I will end up replacing all the speakers in the end. Then I will add giant subwoofers and a huge amp and lower the truck, so I can cruise around with window pounding sound for everyone to hear. JK.

That scene reminds me of when my brother was living on a mountain by Grass Valley California.
He would build his speaker cabinets for various purposes.
One style was to put the sound out there.
Me and the sons was over visiting. On the Sunday before we were leaving He got the equipment set up and called the band together for a grand party, even kegs of beer, amongst other items.
The band was a rockin along, people dancing and having a good time.
Pretty soon see someone approaching, from a long ways away.
Sometime later He and his little brother get there and tells us, My dad asks if You could turn it down some.
Okay, sure, where’d You come from, He points, way over across the valley, must have been five miles. I asked if it was that loud, the kid says oh yeah, it is louder over there than it is here. 😹😹😹😹

Grass Valley has got some bears!
 
OK I verified the rear roof speakers are not work and the control for them on the Pioneer Head Unit is greyed out. Did some YouTube research and it’s due to the parking brake line. I simply grounded mine to get the head unit to work, but it still creates issues with the rear roof speakers. On the Pioneer models the parking brake wire needs an on-off-on signal and simply grounding it won’t allow certain functions, including the rear roof speakers. This is explained in the following video. Then at 4:49 mark he explains option 3 which is a DVD bypass relay. I will pursue that option.

 
This might also be whats going on with mine in the 93. video is disabled on it due to the parking brake wire, but grounding it didn't do anything.

not that I want to be watching any video's while driving LOL
