Hello all...

This is my second Terrain Denali, replaced a 2015. Loveeeeeee it so far but I notice recently that the rear speakers are horrendous. Very very low level and distorted/crackly. Seems pretty consistent regardless of source or type or program. When I fade all the way back it sounds like a cheap transistor radio. Is this "normal"? My dealer is a good distance so I'm trying to avoid wasting a day or three troubleshooting for nothing.

TIA
Paul

Hello Paul, I have a '19 Terrain SLE. IMHO, the standard radio stinks. I'm a 70 y/o senior. Yes, the rear speakers are virtually useless. After nearly two years and only 11K miles the seats are still too hard and the bolsters are uncomfortable for me. I'm 6' and 185 lbs. I have looked at other GM vehicles and hard seats seem to be a norm. Sigh...

The rear door speakers are of lower power and volume level on most GM vehicles. The design criteria seems to have lower audio output in the rear passenger area so as to not drown passengers out and permit some level of conversation with front seat passengers.
There rear door speakers are more of a "fill" type function. IT was the same in our 2015 EQuinox LTZ with the premium Pioneer system and in my 2017 Colorado truck.

You could add a separate amp and new speakers for the rear if more power and sound output is desired.

A cheap set of aftermarket speakers are light years ahead of the stock ones.
My '11 Tahoe LTZ w/Bose has the same door speakers as my old '09 Malibu LS with the base no nothing radio.
I'll wager they are the same ones used in yours. Both of those vehicles got a cheap set upgrade where needed. Malibu's are known for door speakers failing. Upgrading all 4 in the Malibu made the basic radio come alive for cheap.
A $50 set of coaxials in the rear doors of my Tahoe really made a difference with it's surround sound. Rattling one forced their replacement.
