Hi guys. Back in 2014 I pulled my factory HU and replaced it with a pioneer avh-5700bhs double din. I kept the factory BOSE system and just used a cheap 10 dollar wiring harness from amazon. I don’t have any Chimes which is what I wanted in the first place. Here’s where my confusion comes in. I bought new alpine 610 6.5 inch component speakers this week and went to install them today. Had to do pretty good trimming on the mounts that hold the Bose front door speakers but they fit well. Now after browsing the internet I keep seeing that since I didnt buy the expensive gmos-04 harness I’ve completely bypassed my factory Bose amp and it sounds like I’m running my factory speakers directly from my Head units built in amp. Does this make any sense? Or am I reading all this info the wrong way. Also, I’m seeing that maybe I can’t run these components up front because they are 2 ohm stable rather than 4 that the Bose system uses? Kind of confused.
