Hi CA, I would like some experienced opinions and/or suggestions on how to tune or equalize properly my interior speakers. In a 2002 nissan maxima I have 6.5'' cadence component speakers on front and 5.25'' beyma mid high speakers on the rear, powered by a 500rms 4 channels amp.
I recently installed an eql from audiocontrol to eliminate some bass and get clear sound from the interior speakers, but I've tried some much to get it tuned right, but I can't get it to sound right, and after that the sound output is also lower, and now if I put the volume loud on the hu the interior speakers start to sound like with some cracking sound. Also, if this helps, I recently bought an nano oscilloscope but haven't used it yet.
1-What can I do to fix this issue? If possible, with specifications.
2-Is it better to buy and put bass blocker filter to each speaker to eliminate the use of the eq? If yes, which is the best frequency to buy the blocker?
