Hey, i've got a 2019 Jetta S - great car, but base model and the sound is completely wretched. Figured this is a good opportunity to take on a little project.
I've got a pretty solid grounding in EE stuff, but basically no practical automotive audio experience beyond watching others nearby, so I have some questions about this project that you folks might know the answers to.
I acquired one of these: Soundstream Reserve RSM4.1200D
I want to initially use the 4 existing speakers, as i've heard they aren't particularly bad, though eventually i'd like to put something much nicer inside.
I've read that it's the amplifier in the infotainment that really sucks in this car. I'm not looking for masses of power - if I can get even a good sounding 50W/channel for now, that would make me a v happy camper.
So, my questions thus far:
- There are 2 fuseboxes - engine bay and interior. The interior fusebox has some spare holes. With amp installations, people seem to run a new wire to the battery with an inline fuse. Is there a reason for this beyond installation convenience? Could I for example, add a 25A circuit to the interior fusebox?
- All the speaker wires run to the quadlock at the back of the infotainment. Is it a reasonable approach to leave them in situ, and route new wires from those ends behind the radio, down to wherever i'm putting the amp (perhaps under a front seat)? Or is there a good reason I should pull the wires out and reroute them? (thinking about my options if I want to sell the car down the line, here).
Much appreciate any responses you have for me!
