Hello, I am new here. I bought my 17 Malibu in April of 17. It just went out of warranty and I changed out the original speakers on my 7" base radio with Bose speakers. I ordered them from Rock Auto. They sound better to me. I did have to trim each speaker where the input harness plugs into the speaker. There is a tab on both original and Bose speakers. I snipped the tabs with a small pair of shears. Just wanted to do it. Lots of work to do it and since I am 62 years old, it is more of a chore for me than it would have been 30 years ago.

Mine is a 2019 so I still have over a year on warranty. But I'm thinking about doing the same, especially the back speakers. The factory speakers are just 6.5" paper cones with a whizzer cone on it for a tweeter. You would think a $20k car could afford better than a 98 cent speaker eh? I'll probably replace with the popular 6.5" Kickers. Synthetic cone with UV resistant foam roll and a real tweeter. Should give better bass even if I keep the front pair. I did the same on a 2008 Pontiac and it was a big improvement. I'm just trying to decide whether to wait another year.

I wouldn't worry about a speaker upgrade with the warranty.
Better speakers in a $20k car LOL, my '11 Tahoe LTZ w/Bose has the same door speakers as my old '09 'bu LS . Had a LR rattling in the Tahoe.
The 'bu FR door speaker went dead, I upgraded all 4 and the base LS stereo had enough bass to vibrate the inside rearview mirror. At least the '09 had 6x9 in the rear deck.
Both vehicles used 4 ohm speakers BTW, at least that was marked on the originals.
My OEM speakers didn't have any + or - markings so I had to consult a wiring diagram to get polarity correct for the replacements.

Something funny along the lines of speaker upgrades. I bought a 2018 Premier that had a sticker of $35,468 that has the Bose system. I thought the sound was decent at first. After a while as I listed to more music I noticed the bass was muddy on some songs. I decided to check out the rear deck speakers for a possible upgrade. Under there I saw a Bose part number sticker with another sticker sticking out under it. I pealed off the Bose sticker and it was a white acdelco sticker with a part number. They just put a bose part sticker over a delco sticker? You can buy the "Bose" speaker for $63 on gmpartsdirect but if you put in the delco part number it is only $15.78. I started searching the part numbers and found out Bose likes to just license the brand name to OE speakers that "meet rigorous Bose quality specifications" rather than mfg the speaker.

Yes, I suspect that ac delco makes all the speakers. I do get a better range of sound but I knew going into this that the Bose soeakers are only a marginal upgrade. The factory gn systems have always been a odd ohm value. In the 70's the factory speakers were 5 ohms. Replacement speakers were 8 ohms.
