I removed these items from my previous car, intending to install them in my next one. Includes speakers, a subwoofer, and an amplifier (^ ^) I tried to install them, but the sheer number of wires overwhelmed me, and I gave up. I believe everything is there, but depending on the car model, you might need additional wiring, which you would need to provide yourself. These items cost a considerable amount to purchase, so why not take advantage of this opportunity? (^ ^) Sound quality was excellent. Price is not negotiable. No claims, no returns.
