2000 Buick LeSabre Aftermarket Radio (HELP!)

Asked by LordNebula Mar 30, 2020 at 05:53 PM about the 2000 Buick LeSabre Custom Sedan FWD

Question type: Maintenance & Repair

So, I recently purchased a Buick LeSabre 2000. The first thing
I did (Naturally, as I do with all older cars) is rip out the stock
radio and place in and aftermarket Pioneer or Kenwood.
Whatever works my fancy I suppose. I've asked around local
shops and spent hours searching the internet and using my
own knowledge and for the life of me I can't get this to work
properly. I bought a wiring harness and correctly spliced the
wires (it was the harness without the adapter part that
allowed door chimes and what not but I don't think that's the
cause of my problem) only to discover that I needed to hook
a inwire fuse under the rear seat and wire it to the back of the
dash into the radio itself aswell. (Fuse #12 with 10amp fuzes
in both slots of the inwire and a 10amp fuze in the housing of
the radio) after all was said and done and I got power to the
radio I could finally hear music in my new car!
Following that sigh of relief of annoyance I decided to put my
aftermarket speakers in aswell. In the front door panels, and
2 additional ones in speaker boxes on top of the rear window
deck. After playing from there it sounded as if one of the
speakers in the boxes were blown, but just one of them, so I
removed them both. Following that both rear speakers, stock,
sounded blown too. Then about a 2 block drive later, all
speakers were sounding like absolute trash, fading quieter
here and there until completely going silent.
I checked all fuses, with the fuzes in the inwire fuse in slot
#12 popped I replaced those and the audio fuse in (I believe
#21?)
After that, no audio still, other than for a brief second and
then absolutely nothing again. I still can very rarely hear clear
as day, with no cracking, my radio interface beeping while I'm
messing with the settings to try and fixed it, but only when I
swap inputs. When I try playing through Bluetooth I can hear
it clearly for probably half a second when I turn it off.

It's become really frustrating and a major turn off for this
otherwise enjoyable car. I'd really appreciate any insight or
suggestions.

If it helps any, and I plan on fixing this, my engine will stutter.
Both in idle and drive, I think it's the alternator but I swapped
that out from a donor car which unlikely, but totally could
have had a bad alternator too..

TLDR: Car speakers won't work anymore, I don't know what to
do!

If requested I can post photos aswell.
