Sub placement

[G_MAN75]

What do you guys think about putting some subs (size to be determined)
in the back hatch panel. Anybody try this already.

Of what car?

 

[P-Funk!]

I had good success building a box for two 10"ers and making it a sub floor in the hatch...

I was just thinking a just making a panel out of MDF like the one it has now and placing maybe two 15" cause of the volume available .
Just a thought

 

[sndsgood]

are you building and enclosure or are you trying to run the free-air?

Sounds like he is just going to drill holes out of the hatch panel and stick subs there. When I had a hatch back, I had the enclosure firing back towards the rear, slightly angled up (maybe 15 degrees) and it hit really hard!! This was 2 SoundStream SPL12s in a small sealed enclosure getting 300 watts to each RMS. No dimming of headlights either in that car (Mitsu Eclipse)

I was thinking

Well yeah i was thinking free air but sealing the trunk as best as possible with maybe rubber linnings. If not then maybe two 10" in a box enclosure in sitting in top but flush ofcourse (dunno) which can easily be removed.
ANy opinions
Thanks

Free air subs suck ass! I would go with a small sealed enclosure if you don't have any room. You can have a nice sounding system with a single 10" sub. Don't expect to be heard from miles away, but you will definitely have some umph in your music!

hmmm

See I'm a bass head but also like quality sound aswell, so i need the best of worlds, see i have 4 12"s isoberic in abox right now but takes up way to much room in so I"m just thinking of something that isn't expensivley custom but easily taken in and out too, nothing permanent you know?

how about a fiberglass box? kinda messy, but you can get a decent size box in there without taking up that much room. i had 2 12s in my trunk and still had more than enough room for whatever else. both cost me about 120. so its not too expensive.

Word of advice, angel the subs away from the front of the car, as it has been proven, subs pointing forward, can cause hearing damage. But then again, I like hearing, and everyone is different. Also, I think a nice small fiber glass box would work nicely...possibly two 15's, but like, 3 10's would also work. Also, look at some of the pre-made free air design boxes out there, there are some really good options, for space saving that is.

always go sealed for best SQ ALWAYS but make sure you have a powerful amp, even with a sealed box you can sill have it look good. fiberglass kind sucks for enclosure material so try makeing a simple box for the sub out of 3/4 MDF then fiber glass over that if you want a custom look

 

[sndsgood]

first off free air subs dont' suck they can sound just as good as anything else. the #1 problem with free air subs is nobody understands how to build them, they just assume u can throw them in a rear deck or just sit them in the trunk and they are supposed to work, to get them to work properly you have to seal off the entire area between the subs and the interior of the car. this takes more work then most are willing to do. and isn't very effective in a hatchback. rubber won't do, you need to seal it with 3/4" mdf same as if you were building a normal box.


ported will have great sq and more bass if built properly. problems is most people dont take into account driver displacemtn or port space requirement and they tune it way to high for accuracy.


and with most of the subs and power people run today hearing damage will occur no matter what direction u point the sub, bass waves are omnidirectional.

Sealed is the best for SQ, but you can get the best of both worlds with a ported box if tuned correctly. GotWake designed and built mine and it hits hard and sounds great with just about any music, which is great since I listen to a wide variety (except country). (band2)

Great

(hump) Thanks for all the input guys

As Sndsgood has already described...

You cannot make a free-air setup in a hatchback...it just doesn't work. Air can pass through the seats, around the edges of the MDF panel, and there is no way to seal off the back portion where the hatch comes down. Free air requires a seperate airspace from the cabin which is why you only see them in sedans.
