ill speak from experience on this. I used to eat sleep breathe car audio. tweaking things every weekend etc. Then I needed a part time job to help fund it so why not do car audio? STarted installing at a circuit city and while I learned a ton, I do not have the drive to do it like I used to. Ive been working on my truck now for a year and a half and dont have it anywhere near completion. it takes me like a week to build a box and I have every tool needed to do so. if you love it leave it as a hobby.
