Hi Dammit - I've read a few of your posts and think you live somewhere along the Front Range. I bought a '17 HRV EX and have loved it so far. Thinking it would be nice to do a modest stereo upgrade (my hearing sucks). Wonder if you have any experience or recommendations for local services which could improve sound quality over stock for around $500.... I don't really have skills to much mess with electronics, and skeptical of places like Car Toys, etc. Thoughts? Thanks! - David
