For the price, this radio (with Bluetooth capability) produces great sound. I installed it (using stock speakers) into my 1999 Subaru Forester. The wires are clearly labeled, with the only exception being that the speaker (-) negative wires are grouped with the speaker (+) positive wires. The negative speaker wires are distinguished by a black stripe on the length of the wire. Not hard to figure out, Some people may be confused perhaps, so just saying. 🙂 5 star for price and sound. The faceplate and controls on faceplate are cheaply designed and built, but again for the price I can not discount a star for that! Love the Bluetooth function as well as the remote control. The radio pared simply with my Android Galaxy S5.
