Hello guys, I just recently installed an SVC mm2084 8-inch sub in a .35 cu.ft. box in my backseat of my Honda civic where the rear center armrest used to be. The sub fires towards the front passengers and is powered by a hifonix titan txi6406 with ch3 and ch4 bridged feeding 340rms at 4ohms.
From where the sub is located now, the sound seems to bounce of the dash and windshield to make it appear that the bass is coming from the front which is what I wanted in the first place.
The problem is, If I set the subsonic filter on the amp lower than 35hz, there seems to be a noticeable delay in the bass coming from the sub and is not in sync with the sound coming from the front speakers (db 651).
My current settings for the front are hi pass at 40hz. Sub is set to 35hz subsonic and 90hz lowpass.
Can someone help explain why the bass from the sub is delayed if the subsonic filter is lower than 35hz? Thanks in advance.
