I forgot to take more step by step pics but here is a couple of the box I finished last week. Sounds really good. Jl E6450 amp with a 12w3v2 sub. Next need to put an eq in, alittle tweaking of the system is needed.[IMG][/IMG]

Looks freekin awesome Welcome to the club.

Looks nicely executed... how much volume did you get?

good job dizzy1, curious about the volume of that enclosure as well...looks pretty compact. Also, I have that amp as well...how do you have the sub wired to it?

dizzy1

I filled the box with water to measure the volume, I came up with .9 cubic feet so I had to stuff the box with 16oz of poly fill to make the box seem bigger to the sub. The recommend spec for the sub is 1.25 cu. ft. With the poly, its probably about 1.1 cu. ft. A little small but wanted to squeeze it into the corner with the amp so I could fit the kids strollers and my RC junk when I hit the track. Sounded alittle off with out the poly, once I packed in the poly, the sub came to life and sounds great.

I have channels 5+6 bridged powering the sub. Its a dual 2 ohm version so the amp sees a 4 ohm load bridged on those channels. It should be putting about around 200 watts rms wired this way. I was disappointed in the output but my accord had 2 15" JL w6's with a PPI A1200.2 pushing them. Quite a drop in power and speaker cone area. Still sounds good though.

very nice, I love making things out of fiberglass now.....

looks great... how much should i expect a shop to charge me for building a box similar to this... also i am guessing you made this yourself, do you have any DIY for building this type of setup... i have the sub, i am just tryin to figure out how to set it up to not get in the way of anything in the trunk...

Poly can give you 10% more effective volume tops, as I recall. 20% is pushing it.

But nothing twice as much power and an EQ can't take care of...

setup looks good, here's a question for ya (probably a dumb one):

How did you mount your amp to the trunk wall like that?

Thanks.

Looks great.

The amp is mounted by 3 brackets. For the top, there is a factory metal bracket for the trunk lid, a plastic clip goes thru the carpet into it to hold the carpet up. I bent a bracket to contour behind the carpet and replaced the plastic clip with a bolt to hold the new bracket and then attached the top of the amp to it. The bottom 2 mounts are metal triangle brackets screwed directly into the floor and holds the bottom of the amp, you don't even see any of the brackets.

ELD- I always read were a few magazines tested different amounts of poly and its effects. In general they found that about 16oz of poly per cubic foot gave approx 20% gains in volume. I think it was around 20oz per cubic foot that the volume actually started to drop since the poly was so tightly packed. Maybe I am off, just how I remember it from back in the day. I need to get an eq, just debating what to get.

on the poly note, would it make sense to stuff a ported/vented box?

I'm going off of my memory of the Loudspeaker Design Cookbook and my own testing. The LDC might be describing open air performance and the diff might be in-car, but my results didn't support that.

Get a PG 4-band parametric See my sale post.

I just picked up a Clarion eqs746. Cheap and I always like clarion stuff. I'll post once I get around to installing it if I get any noise or pops since it seems to depend on the equipment installed if you get the noise. If it does, I'll have to spend alittle more and get the Audio Control Four.1 since it has balanced inputs and see how that goes. Hopefully the Clarion will pan out.

very very nice. would a W6 fit? doubtful right?

dizzy1

A w6 or w6v2? The magnets on the w3v2 seem very similar to the old w6's. I had about .5" of clearance on the corner of the magnet to the rounded corner of the box. Don't think a w6v2 would fit, those look pretty deep.
