Just wanted to throw some images in - today I hit 300 miles and I wanted to make some changes to the audio system.
Tried putting my old G2's in there... rendered trunk useless.
After doing some research and testing, I understand that my BeSpoke powers the front dash speakers/tweeters, and the rear speakers. There is a small amp in the back that powers the door mid-bass.
I am going to replace the factory amp with my Pioneer GM-D9500F 4 channel amp. The first channel will power a pair of SoundStream RBC.6 components (door speakers & the tweeters)
I will leave the 4x4" speakers to be powered by the receiver for now,

We'll see if the dynamat is effective. I'm hoping the components will add the depth and clarity I'm looking for.
