trunk rattles like a mothafu**er


Recommended Posts

Ok so I just put my 2 obsidian 12s in my trunk with my bt-120 & zx1500 wired to 2 ohms,

My gain is only half way cause I didnt properly set my gains yet,

From outside the car you hear it from 50ft away, at 25ft you hear nothing but rattle from my trunk, wing & rear bumper.

I was wondering if I face them towards the front near the opening I have through my rear seats how much quieter this will get and if the rattles will stop being so bad.

Equally as loud then?, less rattle?

even if you flip them around your still going to rattle get some Second skin to help with that and even turning your gains half way can still clip your signal and is that a pre fab box?

It might not be as loud if you do that it was loudest for me subs facing back of trunk or you can just seal it off

you obviously arent loud enough yet :peepwall: jk. do what works man, you have a rare case

OP still need to sound deaden trunk. but face in and 9/10 youll be louder. there are cases where it wont be louder even to seal off such as tdsa. but just try turning around and see if you like it.
