[bad @SS chevy 10+ year member]

i have subs up port firing into the cabin.... But for my HD3 build i had the port and subs firing into the cabin, trunk sealed off and it was MUCH louder then when i had the subs and port firing towards the liscense plate.... But subs up and port firing into the cabin is mucho loud as well...

subs up/port into cabin.

Remember to push box all the way to the trunk lid. Everyone has a tendency to believe that by pushing box forward acts like its sealing it to the cabin. Not True.

Each box I've built has lost DB's by being pushed forward. Build the box as big as poss to fill out as much of the trunk as you can. Then seal it!//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

Interesting thread. I as well want to become one of the loudest trunk cars around. I am planning to compete but um... thorshammer1 I was under the impression that pushing the box foward as much as possible seals the sound in the trunk. that is a great tid bid of info.

^^Thanks. I'm dedicated to this GP for the next 4 yrs. I love to show the world that you can get a trunk vehicle loud. It's just Friggin Hard! LOL

I just noticed in your Avatar that you live in NY! I'm haveing a St. Judes Charity car show this Sun in Auburn, NY! You should make the trip out and support the children. Plus I could show ya what I've done so far to my trunk.

Sorry bout the thread jack. lOl

for those who did subs/ports forwards, did you still have a backseat, and if so what did it sound like when the seat was up?

I keep my backseats folded down, but when I do have them up it sounds fine...just not as loud

how do you properly seal the trunk?

how do you properly seal the trunk?

x2

I'm thinking about cutting the material that blocks my center armrest out and facing the subs/ports toward the inside of the car... I'll have to try some experimenting

how do you properly seal the trunk?

expanding foam, duct tape, fiberglass, cardboard, raamat, some old socks, thats a good start.

 

[muskyhunter567 10+ year member]

to seal off the trunk i was thinking build a mdf baffle maybe even double thick, that the subs are in and then just build the rest of my box off the back of that in the trunk and fiberglass resin the inside before i put the backside on and maybe fiberglass around by the edges by the subs to seal off the trunk from the cabin, yes no maybe? and p.s. ive never db tested anything ive got in my car, how would two hifonics 1606D amps on two 15" kickers do sealed from the trunk ported in a 4.5 ft box for each tuned to 33hz on a good eletrical do? like 140s?
