Started making a partition/sub box yesterday and got the rough product finished. Now to let the glue and RTV dry before throwing the sub (Infinity Kappa Perfect 10d VQ) into it and see what it sounds like. If it's good, then I'll carpet it. I have around $50 in supplies not counting the carpet.

 

 

Nice

 

Not yet completed, have to do something with the ports and order a grill. My first time gluing carpet on.

 

Looks nice. Cant wait to see it in the car. What amp will you be using?

 

Head Unit: Clarion DXZ785USB /w 160G external hard drive
Front: Speakers: Infinity Kappa 60.9CS
Rear: Speakers: Infinity Kappa 52.9i
Sub: Infinity Kappa Perfect 10DVQ
Amplifier (s): Infinity Reference 475A 4 Channel (Front/Rear)
Infinity Reference 1600A (Sub)
Box: ZEnclosures, Flush Mount(Soon to be custom box.)

 

Some of it in the car.

 

That came out great! I like the added finishing touch with the emblems.. Nice work!
How does it sound??

 

looks awesome

 

This is not a cookie cutter box. I took Thiele small parameters and the mfg cubic ft and tuning recommendations to make the box.

Sound wise, it does have a little (OK, a lot) more thump to it compared to the sealed box. Now that there is a partition, I can actually hear the full range of the speakers cruising down a concrete highway with about 60% of the road noise gone. Just a guesstamate, didn't pull the db meter out.

Before you knew there was a sub back there pushing out the bass. Thump, thump, thump oh there is a bass guitar note. Now with the compartment being smaller or due to the box, I can actually hear the full range of bass being produced.

Noted problems. My car is very well sound proofed/sealed. With the partition/box installed, I have to use a little more oomph to close the trunk and doors, there is to much inside pressure. With the windows up, its basically a vented box within sealed box. You can notice this at higher volumes when pushing the bass. As soon as the windows are cracked about an inch, you can definitely notice a volume gain inside the car.

The 2 Infinity amps look almost the same except for the end caps and I imagine the internals also. I ASSUMED the power block would be the same also (they looked the same) so I hooked up one amp and looked at 12v/power on/GND and hooked it up. I did the exact same thing to the other amp, blew the amp fuses and the amp. Infinity swapped the power/GND around. First time in around 30 years I've blown an amp. Glad I had the Eclipse amp sitting around.

As my brother put it. A $200 amp to protect a 50 cent fuse.

 

looks real good

 

Thats awsome an clean!!

 

Looks better than store bought!

 

Very nice job! You've inspired me to build my own versus buying one.

 

Nice looking box! Ill be taking mine out soon to replace the sub and recarpet it.

I didnt do mine as wide as yours. What kind of Cubic ft did you get out of it? I might have to change my design to get some room in my trunk.

 

where do you put your golf clubs...

 

That's awesome. I wish there was something like that for a vert, but I can see how that might be... problematic...

 

Great looking Box. Could this be done for a c6 vert?

 

It is a Vert, isn't it...

All I can say is WOW, that came out beautiful.

I love the Kappa Perfect series. You don't have to throw a ton of power at them, as they have a very high efficiency rating, and they are truly a SQ sub. Hard to find a better sub for the dollar.

I may have missed this, but what was the displaced volume, looks like a little more than 2.0?

Two thumbs up on a great build, and a wise choice in woofers, that thing must sing!

Oh, question... You said that you can hear more of the range of the woofer than just "thump", were you using a different woofer prior, or is it just the larger ported box that made the difference?

 

Infinity recommended 1.75 cu. ft. for a ported box. For a sealed box, .3 to .75 depending on the insert used in the sub.

Golf clubs? I pass a lot of golf courses while I'm driving the Corvette instead of golf *****.

I would have to look at a C6 vert with thoughts of installing a sub box.

It's a FRC, Z06. 1.75 cu. ft. Same sub but in a sealed box. When the car wasn't running, it sounded nice but with the road noise.....
