Beat Sonic Genuine Audio Good Sound Kit DSP amplifier TOON X is for sale. It is compatible with the late model Corolla Touring with 10.5-inch 6-speaker system. The part number is DSP-T318. Originally, it's plug-and-play with no troublesome wiring, but the previous owner used direct wiring, so the wires have been cut. I got it cheap in this condition, but I don't know how to wire it, so I'm selling it. It originally costs over 50,000 yen, so it's a bargain for someone who can do the wiring. How about it for those who can handle wiring themselves? I have checked that it powers on. Shipping included.
