BTW this is going in a 98 Grand Cherokee and to the ear there was more pressure/intensity of the 40-50s range with sub up, port drivers side possibly better numbers hard to tell by ear. Lows seemed about equal between sub up , port back and sub up, port drivers side, maybe a little bit better/more solid sounding lows with port back thats why Im leaning towards that since I dont care about numbers really and probably will never get it on a meter around here, I just like nice daily that can play the lows decently.
Just saw this earlier during research phases:
He has a 97 Grand Cherokee and was hitting loudest (didnt say numbers but sounds like he was metering it) with seats down box back away from hatch and aiming at a diagonal towards the passenger rear/hatch corner.
He also said sub up, port drivers side was pretty good thats what made me try moving the box around a bit.
I am going to try them all again with a few different tracks each:
-sub up, port back
-sub up, port drivers side
-sub back, port drivers side
-sub drivers side, port back
-sub drivers side, port up
-sub up, port diagonal to corner/hatch
See what I come up with sounding good to my ear.
Dont want to have to build a bunch of different boxes to get this right since I probably going with birch this time and double layer whole box too so thats more wood wasted if I end up rebuilding (dont want to do that).
