Firstly set the SPL at the middle of the car close all the doors and shut the windows too, play a spot frequency say 20Hz 30Hz and 40Hz etc though to 80Hz and then re-positioning the sub bass and repeat the test all over again. Good luck http://www.hifi-writer.com/he/applianceretailer/receiver-setup.htm https://www.ecoustics.com/electronics/forum/home-audio/146507.html |
