you dont need to get one with 3 outputs you can get a nice one with 1 output and buy a splitter, which is cheap, and you can go from one to 3. a radio with one or 2 outputs will be easier to find with one with 3 outputs. my radio that i have is a boss 7 inch flip out screen that i got off ebay for around $225 if im not mistaken that is about 138 pounds. it only has one output but i bought a splitter for it for a round 3 pounds. its a great radio for the money.
