PCPartPicker style website for car audio
Since my first build, I can't stop thinking about this idea:
I don't know how many of you know PCPartpicker, but it's basically website for building PC's where you can compare prices, share builds and check for compatibility of parts.
I'm thinking about building something similar but for car audio. Main idea is price tracking, sharing builds and more advanced modular builder where users can connect components and check if it will work together (impedance, wire thickness, etc). I also want to add vehicle compatibility similar to what Crutchfield does later.
What features would you want from something like this? I know advanced builders probably wouldn't need it as much, since you already know what goes together and you can usually get good deals from local stores, but I feel like there's place for a tool like this to help beginners plan builds and get better deals.
