How to access and replace the rear speakers in a Pontiac G6. Mine is a 2008 G6 but i believe this will apply to most years. This video focuses mainly on process of accessing the speakers for replacement. Plan on this process (and it IS a process) taking the better part of 2 hours, and leave room to remove the seat out of one of the rear doors before you start. It was a pain in the butt, however it was well worth it as the new speakers, even with a factory (non-Monsoon) radio, sounds so much better when it’s done.

Are the stock speakers 3 ohm like these JBLs? The fronts I believe are 4 ohm. Strange.
This probably applies to the same year Malibu also.
WTF??? I watched the other guys video twice, went outside and had all 4 speakers out in a half hour…your front speaker vid is good…but this is way too involved…LOLOL
Yow, all that to replace speakers?
Hey SH72, I helped my friend replace his rear speakers and we twisted the positive of the tweeter and speaker, connected to positive of new speaker and negatives of each to the negative of the new speaker.. Any volume it has tons of distortion. Any tips on what to do?
Why the fuck do they make it so you have to take half the damn interior out to change speakers. I remember in some older cars you would just pop off a grille, unbolt the speaker, unplug the old, plug in the new, bolt it in, and pop the grille back on.
thinking its micheal cera behind the camera and teaching me how to install some speakers
Thanks for the video, I was trying to take the deck out without removing the seats. However, wish I'd read the comments before I started this project because I too have the monsoon system. Havent even seen how speakers are wired but since I have my car apart already might as well see if I can figure out a way around the wiring issue. If I do, I will post.
It works for 07
thanks man for the tutorial I did it to my car but the black plastic on the sides of the seat belts u didn't have to take that out at all but thanks tho
the plug has four wires total how did u wire the back speakers up?
i have a coupe and i don't know what's wrong with the factory stereo everything thing work but the sound doesn't come out. is there any factory amp in g6 gt?
Great video, I just completed this same job with the help of this video. It was a lot of work, but i enjoy doing stuff like this by hand. Only thing that would have been nice is to overlay text or something to list tools needed to complete the job. Thanks again!
great video, it helped me out alot and saved me money, it was actually easier than it looked, thanks great job
Great video Good Old GM Over engineered rear shelf but paper crap speakers go figure ….I'm sure it sounds Way better I'm glad my 1997 Pontiac Bonneville rear deck was a lot easier
Thank you for uploading this video. Did you know this job can be done without removing the lower seat portion? All you have to do is lower the seats, take the pillars out, take out the four bolts on the deck on the upper seat backs, and pull the deck out. The tutorials on the G6 Forums all recommended the above steps over taking the whole thing out. Now on the coupe it is necessary to take the entire seat out.
So the aftermarket speaker has different connectors ? Thanks for the video
thanks for the vid bro really helped out. was not expecting all of the work for this just to put in speakers
I was going to do this myself, but after watching this video i just took it to a shop, screw that lol. Very informative of the process though! Thanks!
this helped so much thank you for making this
I have a 2008 G6 too.Such a great good looking car!What a pitty GM make it a lot of maintenance complicated.Thanks for your video.
Dear god, why were these cars so horribly over-engineered…
awesome video, but I have a coupe, just gonna have to pay the local audio shop for the installation lol
So, the part when you unscrew the bolts, i accedentaly detahced the wires, and pushed my seat up, and now i cant put my seats back down. Any help please.
Im gonna try to just pop off the grills. Even if I have to glue them back in
How did it end up working out? I'm about to install a set of MTX Terminators in the front and back, with a factory head unit and I'm just worried about it being underpowered, etc. I just kinda wanna get it back to AT LEAST factory sound, and this is cheaper than buying the factory speakers ($75 per speaker, not pair, at my local dealership, more for the 9" in the back.)
I'll be doing my girlfriends g6 tomorrow…. Thanx for Sharin' this info! But man, no wonder Pontiac went out of business. You should see what I had to go through to replace the radio! Smdh I'll post my progress as I go along
I have a Coupe… this is going to be interesting 🙁
Sick guide, I'll probably be trying this when i get enough free time and a nice enough day, is splicing required if i replace with OEM speakers? i replaced my door speakers without having to splice/soder
