Alright I got around to installing my speakers and something isnt right. The rear doors sound pretty good, the front doors sound empty and mostly just hear some instrumental, and the stock dash ones sound by far the best. I'll post a screen shot of my order. I know jack $$$$ about sound systems so please be patient. Thank you in advance.

Can you confirm if you have the Bose system or not? And if you do, did you bypass the amp and wire straight to the HU or not?

All the original speaker mounts had Bose stickers. I just used those adapters and clipped them to the old speaker wires

Likely the impedance or specs of those speakers aren't matched to the Bose amp. I saw with that order you also had a HU. Did you get a proper interface to connect from the HU to the stock wiring harness to work with the amp?

The connectors I bought went straight into the trailblazer wiring harness for the head unit and speakers so I think so. As far as the amp goes no I didn't I just bought speakers that were recommended by a friend.

It's the impedance. With the Bose amp, they're 2ohm and you're now running 4ohm speakers. You'll either have to get another amp and run all new wire or run new wire straight from the HU to the speakers and forgo the dash speakers because the crossover for the fronts is built into the Bose amp.

For someone that has never ran speaker wire how tedious is it to do? I have experience with wiring and electricity so I'm sure I can figure it out just not sure how time consuming it is

If you have a wire snake, or a fish tape, that will make it a lot easier getting behind the dash, and fishing through the rubber boots in the doors. If you do, then the majority of the time will be spent pulling panels off.
