not getting the bass i should.. should i port the rear deck.?orion hcca and zapco..

[kickerfanatic]

o.k here is the deal..

in my wifes car which is a 1987 oldsmobile delta 88, i have a 10'' orion hcca in a custom ported 3.7 cf box being pushed by a zapco reference 1100.1 amp..

sub is dual 4 ohm wired down to a 2 ohm load.. all my wire is 4 gauge.

i had the sub in a regular small 1.5 cf ported store bought box and it was not loud like to should have been so i made this custom ported box for it expecting it to be louder.

but its like its not even on most times..

if i run a bass track or a hertz test i can hear the sub plain but it still dont even sound loud.

im thinking its the trunk of the car.. its completly sealed.. behind the back seat is a full metal wall. and then the solid metal rear deck.

if i open the trunk in my garage and play the sub at my loudest volume i always put it it will sound crazy loud and incredibly deep.. it rattles everything in my garage..

also when i bench tested it in my house with a kinetik kc1800 it rocked the shit out my house..

but in the trunk of my car its not even loud at all.. sounds like a 10'' lightning audio sub or something..

do i have to port the rear deck.. should i cut a few 4'' round holes in the rear deck or something...?

what do i do..?

is my problem that im not getting no air into the cabin of the car and thats why i cant hear the sub..?

If theres an arm rest in the back seat fold that down and cut a hole in that fabric and sawsall a hole in the metal and that should open it up so u can hear it.

of corse thats why you dont hear any bass. your going to need to cut away a lot of metal to get some output into the cab.

i unno if it works the same but my bro n law had a old monticarlo and i put one of my old ma audio 10's ina 15'' prefab ported box and made a new baffle to work with a 10'' n it wanged like hell in his car n it has a steel back seat and back deck but someone in town has a monticarlo with 2 l7 12's in the truck faceing twards the seat with it ported threw rear deck in a ported box and it wanged like hell too

i say cut a hole in the rear deck and put a mesh type materiel over it so stuff dont fall down in it and what knot and it should work pritty good

ied say maby a 4''x10'' or 6''x10'' could work, i aint really did it befor but ive seen it done and it worked good too

just make sure u face the sub twards the seat when u do port the deck

and ive even seen someone box up the back of the seat and port the box into the cabin threw rear deck and it sound good too but theres to much customization in that type shit

well i dont have an arm rest or i would have just ported it thru there, but i think i will just cut away a nice amount of the metal behind the back seat even tho there is no arm rest and then cut the rear deck and port it..

the reason i would cut away the metal behind the back seat is because i believe it will sound better instead of the air pressure bouncing off all that metal..

so is this what i shoudl do..? what kind of difference should i expect after i do all this..
