I have a 2011 Moomba with a Kenwood stereo system with on board speakers. I want to install tower speakers with a new amp and a new radio with Blue-Tooth capability.
1. Is there a special kind of radio that i need to buy to be able to plug into what is there?
2. Any recommendations on what size of amp I should get to power the system with the tower speakers
3. What should i use to install a 2 channel system so i can control the onboard speakers separate from the tower speakers
4. Are there any videos out there that show installation instructions

Thanks
