porting through rear deck

[inferno1985 10+ year member]

well i decided to just keep my charger and pay it off instead of buying a suv.

so now i really gotta think about a enclosure design since its going to be in the trunk rather than a cargo area of an suv.

my seats dont fold down. and only real good option of getting any real good sound is porting through the rear deck. i have a factory 8 inch sub cutout i the rear deck. so i was thinking about using that to port though.

also should i just go standard subs facing rear of trunk and port through the hole? or should i turn the subs around and point them towards the backseats and port through the hole and seal it off?

or does that not make any difference because my seats dont fold down.

Have you considered IB through the back deck?

If you're porting through the rear deck, do a 4th or 6th order bandpass and seal the cabin off from the trunk.

Why?

Why?

A trunk is an extremely lossy part of the car. If you can eliminate that, then why wouldn't you? Your other option is what, layers of deadening applications and foam and weatherstripping, and you're still going to have loss.

If you port into the cabin with a 4th or 6th order bandpass and then seal it off, all acoustic energy is going straight into your cabin.

infinite baffle Google it. For sound quality build, not that loud. Recone those XFLs.

yea i need to either recone them or get some new ones . these xrs sound nice, quality wise. but they dont pound like them xfls do.

i may even try out some ethos.

i should have just got a suv:verymad:. why must i always make everything difficult lol

also the thing is im limited on the amount ofstuff i can do without fabrication of rear deck. i have 2 kids 1 is still in car seat so ill need the rear deck seat anchors there still.
