Car audio in 68 Camaro

[Z24]

Hey,

Trying to figure out what to do with my friend's car. As the title says, it's a '68 Camaro. The problem is getting bass into the cabin.

Right now, with 2 12's in the trunk, he gets very little bass in the passenger compartment. I'm assuming it's because the car is so heavily built, and the back seat has a lot of metal and heavy padding in it. (does not fold down)

One thing I've been thinking about is a bandpass design that ports up through the rear deck. Thing is, I don't have a lot of experience with bandbass box designs.

Has anybody done this, or know anything about it? I'm sure I can figure out the bandpass aspect of it with enough research, but porting through the deck--is that a viable option?

And why would you want to *ghetto* out a car such as a 68 Camaro????Leave it stock with the original 8 track

Have you tried the subs in a different car?
Could be improper box sizes, or not enough power pushing them.

 

[Z24]

Not my car, not my decision.

The bass doesn't need to kill small animals as you drive by... it just has to sound good.

Probably gonna put a nice 6.5" component set up front (100W a side or so), *maybe* something off the deck for rear fill, and then there's the issue of the low-end. This is what I'm asking about.

Don't worry--no neon

You should get Oz Subs and an Oz component set...they are the best of the best...and make sure the box is whats recomended for the subs...

viperoni-- fancy meeting you here

The car is in storage right now (for the winter here in Canada). It's quite possible that the current setup wasn't done right, but you *really* don't get much bass outta the thing.

I mean, even cheap 12" subs put out some bass. There are 2 12's (Predator--but I'm not sure) running off an Alpine MRV-T500 (I think that's the model; 300W @ 4ohms @ 14.4V).

Predators are decent, but a bit old



<< I mean, even cheap 12&quot; subs put out some bass >>



No, no they dont.
My friend just built an Isobaric vented box, and although it has decent hit, it has no lower end bass.
So songs like Nelly's country grammer have no shake, just hit.
Pure crap, and a waste of $100.

note: existing stuff is on its way out. Just telling you what it was so that you had an idea.

Anyone know about porting through the rear deck?

 

[Z24]

vortex,

funny you mention that... but Oz is an option. (Friend knows a dealer of Oz stuff)


still need info on how to get bass into cabin. the sound doesn't pass through the rear seat as easy as it does on newer cars. (remember, the car is 30+ years old, and if you even suggested &quot;snapping&quot; something together, they'd laugh at you)

 

[Viperoni]

Using a bandpass box and porting through the rear deck is a pretty viable option, but you have to get your chamber size and port length/size EXACTLY on with bandpass boxes.

A 6 inch port tuned to ~45 hz in a 1.5cf box would need to be at least 15inches.....

Get some old Jensen 6X9 triaxials.

my friend had a 68 Camaro SS for several years, he had a nice system in there, 2 10&quot;s in the trunk, but I'll agree it didn't get near as much bass into the car as my Firebird.. course I have a hatchback not a trunk, and that makes it way better for car audio.

viperoni,

I like the idea of porting the bandpass through the rear deck because in a bandpass all the bass goes through the port.

Keep in mind, since the port will actually have to extrude from the box a bit (up to the rear deck), a long port is not necessarily a bad thing. And you could always use smaller ports, no? (for shorter lengths if required)

EDIT: Any special considerations if you use the flex ports that are available? This would make attaching the box to the rear deck much easier.

My brother's got a older car too, bass doesn't come through very well at all (1 12&quot. He orignally had no parcel shelf in the back, and the bass was really good, but once he got that replaced and 6x9's in there, you can't even HEAR the subwoofer, which really sucks

He's just gonna replace the back seat with a flip down thingy in the middle

 

[Viperoni]

Flex ports - Keep the diameter as big as you can (to make up for the ripples in the actual tube.
Tailor the port size and length to your needs, but remember, since all the bass comes from 1 source, the port, make sure it's as big as it can possibly be.
