Spark rear speaker adapters - 6.5 JBL

thingiverse

Speaker adapters ring up larger speakers in the rear of a Chevy Spark EV or Chevy Spark by mounting them securely. Using JBL GT7-6C component speakers is possible, but they're likely to work with other 6.5 inch speakers too. Don't forget to add foam gaskets above and below this adapter for the best sound quality. They work pretty well overall! You might need to boost the bass in the EQ to power up powerful speakers effectively. These adapters really bring a lot more thump when you push them, though! Be cautious where you mount your tweeters if you're using similar components, or the bright highs can overpower the front speakers and shift the soundstage to the back of the car.
