Trunk porting

[Bigmike 0]

i have 1K on two Fi BL 12 rear firing in the trunk.

would putting a hole in the rear deck improve SPL?that in the cabin

will it cause problem for my 6x9 on the rear deck???

what the best way to do it??

Thanks Inadvance!!!!!

putting a hole there will most likely help with loudness, yes. What kind of problems with the 6x9s do you think might occur? the hole should actually help them because it will release a little more pressure out of the trunk, which puts pressure on the back of the rear speakers. One time a lead fell off of one of my back speakers so the motor wasn't controlling the cone anymore, and the pressure from the sub spidercracked the cone all to heck.

just take the 6x9s out

that would get u 2 nice size holes and u could tell if its goin to help u get more spl. if it does put the 6x9s back in if u want and cut the rear deck to hell

i decide to just take out my 6x9s, because my sub keep breakin them, and i decide to use 4 4in ports to bring in the sound, kind of turnin my car into a series tuned band pass,

then i tried for a new way to port it cuz i wanted some rear speakers, so i sealed in 4 6 1/2in woofers and ported throught my back seat.

are the subs walled off in the trunk then? or just in a box firing forward?

My sub are firing to the rear.I Have 3.5 '' drivers in the dash

with bass blockers on them.without the 6x9,my lower midrange

sound like chit,so i guest i will have't put a hole in the center of the rear deck.

and leave the 6x9 in.

was the for me or the OP,

for mine, the kickers, the boxes where shove all the way back blockin off the back seat whole, so i ported through the rear deck, but the second one, with the audiopulse the box is shoved all the way back again with the sub facin the other way, but it was a temporary box, its a little different now

I could and did, but it was a big hassle, i had to put the seat up everytime i left the car, people around here like to steal stereos Happened once before, when i just took my 6x9s out, and you could see into the cars trunk. Also no passengers in the back if i gotta drop the whole seat down

ya i see your point. im moving my amps up under the rear deck to hid them better.

more power would help in a spl type deal like your asking about.
