Contour Enthusiasts Group Archives Forums Modifications Audio I was wrong about a sub in the rear deck (long...)

As some of you may know, I've tried putting an 8" free air sub in the rear deck to unsatisfactory results.

Since then, it's just been hanging there unhooked.

Well, I decided to give it another try. I got some 3/4" thick felt carpet padding and put it in between the metal and rear deck cover (cut a hole in it for the speaker). I also trimmed out the card-board type of material on the rear deck, which previously covered the speaker (didn't cut any of the carpeting).

Next, I bridged the sub to my amp to give it about 250w.

Now, I am very surprised at how good it sounds. It's not super deep like a 10" or bigger, but it more than fills out the low end the car is lacking using just 6x8s.

I cut the sub at around 80hz and did likewise with my front speakers (stockers). The fronts don't sound too bad either when cut at 80hz and 80w running to them. Not component quality, but definately leaps and bounds ahead of the stock system.

If anyone is interested in pics, let me know and I'll post some.

What kind of irks me is that I just bought a pair of 8" Audiobahn subs that I'm planning on using in the car. Now, I'm kind of unsure of what to do, as the Kicker is more than taking care of the low end. Decisions, decisions...

Hey, you can always give the Autobahns to me, you know!

Tempting.....

Did you cut any sheet metal in the deck or were you able to use the existing hole?

I used the existing hole (no cutting at present). I bottom-mounted the sub to a piece of 3/4" plywood that I cut to mount on the bottom of the rear deck. This gives the sub pleanty of room for excursion, so it doesn't thump into anything.

I also dynamated the top of the plywood and the bottom of the rear deck. I'm not sure if it helps out at all, but I had some lying around in the garage and decided to put it to use.

thats sounds good send me the pic. I wanted to put a ten inch speaker in that portion of the rear deck. You think it would fit.

I think it would work but would require enlarging the hole and adding bracing to the rear deck. A 10" will move more air and cause more vibrations than a 8".

Not in the same way. I have about the same setup as cthomp (different equipment) and a 10" will not fit in the same way. You could put one there, but it upside-down or with an oddly shaped extension.

A 10" would really be pushing it. There might not be enough board left for you to mount the speaker to after cutting out the appropriate sized hole.

You'd definately have to do some cutting/bracing with the rear deck like Dave said.

I'm out of town for a couple of weeks w/o my digital camera, so you'll have to wait a little bit for a pic.

But, it's the same type of installation as APT's. He's got a few pics of his.
