Toyota GR86 options
The GR86 is fitted with a CarPlay and Android Auto capable head unit and 6 speakers consisting of 2x tweeters on the dash, 2x 6.5" woofers in the doors and 2x 3" speakers in the rear. From our testing we found the stock system to be very underpowered, with distortion present at higher volumes. The doors gave a mixture of rattles and vibrations due to a total lack of sound deadening, and a very poorly installed factory water membrane. Rear speakers have very little output and the signal from the factory head unit is rolled off under 500Hz meaning its not really worth upgrading these unless you are also upgrading the amp.
