Trunk open or closed????

Subject: Trunk open or closed???? Fri Jul 13, 2007 3:50 am

First topic message reminder :

Kenny and myself just fineshed a new set-up for his trunk car. We noticed it sounds quite a bit louder with the trunk open. We dont have a TL so we are not sure. (You know how it is when you think ya got louder and ya didnt). I have never seen anyone run with their trunk open. I guess my ??? is.....is it possible to be louder with trunk open? Question

Wha car was he in ? I was acctually there, but didn't run. Sad

Would have been a chitty score anyways from the new box. Time for some work again.

I had Trailblazer with 2 15 firing forward. It hit 2 DB higher with the rear hatch open. Still trying to figure that one out.

you guys beat me to this test matt sibley sat in my car and someone open my trunk and he told me it got alot louder. sooo i was going to try opening my trunk at my next comp. i bet ill gain 1 or 2 db

Subject: Re: Trunk open or closed???? Sun Jul 22, 2007 11:31 pm

I actually did it with the throw together setup at thunder. went from a 42 and change to 44and change. Wink

Subject: Re: Trunk open or closed???? Mon Jul 23, 2007 12:20 am

tested a 99 neon and did 1.6 db louder with trunk unlatched not open all the way just opened the trunk and closed the lid down but not latched...

Subject: Re: Trunk open or closed???? Mon Jul 23, 2007 11:58 am

i might hit 149 if i could gain 2 dbs... i know i can hit 147

Subject: Re: Trunk open or closed???? Sat Jul 28, 2007 5:10 pm

when i have either my 89 or 91 mercury cougar or 86 toronado we put my friends cliff 12's in their with my old rf 500.2 amp and needless to say it shut off every 5 seconds but with the trunk open it was way way louder... this was before we discovered bigger boxes are not always better and louder...

Subject: Re: Trunk open or closed???? Wed Aug 01, 2007 6:06 pm

Hmmmmmmmm

Subject: Re: Trunk open or closed???? Sat Aug 18, 2007 7:55 pm

i gained but i also added a new amp i went from 146.3 too 148.4 and i think i have some in it

Subject: Re: Trunk open or closed???? Sat Aug 18, 2007 10:50 pm

i hit a few db's louder with the hatch open in my mustang.

Subject: Re: Trunk open or closed???? Sun Aug 19, 2007 1:13 am

i say open

Subject: Re: Trunk open or closed???? Sun Aug 19, 2007 3:26 pm

i think the open trunk does help with my setup but like a said i add a new and mean amp. so i think i could of burp a 149 which would put me 3 db higher. cut that in half for each 1.5 the amp and 1.5 the open trunk. still have to play with my setup to find my best score. i will one of these days

Subject: Re: Trunk open or closed???? Tue Aug 21, 2007 2:29 am

well test again with trunk open, then close. That way u can tell if it's the amp or trunk.

Subject: Re: Trunk open or closed???? Tue Aug 21, 2007 9:30 am

that i will diffenently do bro. im curious myself if the amp dod all the work if it did then dam good. i just think it went both ways tech114 why dont you try it yourself

Guest

opening the trunk will change all the variable...res freq, imp rise. air transfer. I would say that if you open the trunk and get louder that just means you have more work to do with your box, ultimatly you should be louder with your trunk closed.

Subject: Re: Trunk open or closed???? Tue Aug 21, 2007 2:08 pm

it depends on design of the box......we have tried it firing forward sealed from trunk and it gains 2 db with trunk open nothing else changes imp rise frequency or anything

Guest

Just means the air transfer isnt sufficient. is all

Subject: Re: Trunk open or closed???? Tue Aug 21, 2007 4:21 pm

you might be right i would have to test sealed up to really see the difference.dont have a meter so i have go blind to the comps. im very happy with 148 in my car

I am working on a mod vehicle; the the vehicle is at rest for the moment. When i get a chance i will do some testing?

Subject: Re: Trunk open or closed???? Wed Aug 22, 2007 10:12 am

it would be nice to see your results. im working on getting a meter so if i get it ill be able o test alot more and give real results myself

Subject: Re: Trunk open or closed???? Thu Aug 23, 2007 1:40 am

we tried it awhile back in an alero and it was 2 db louder with trunk open and woofers forward, i think thatd be the only way it'd make a diff i know other ways that were louder tho than firing forward.........

Subject: Re: Trunk open or closed???? Fri Aug 24, 2007 3:09 pm

well i wont rebuild my box right now im going to get my money out of it...i may get a crx next year then i will rebuild:D

Subject: Re: Trunk open or closed???? Sat Aug 25, 2007 11:22 am
