I want to improve the sound of the speakers in my car and I'm trying to figure out the best way to do it. I know a few people say to get a new head unit but I like my stock unit and it has sat nav etc so I would like to keep it.
Does anyone know if the RNS 510 can be amplified? Does it have a preamp out or do you need to amplify it another way?
Any other information would be great as well.
