MOSFET - 25 Jan 2006 01:10 GMT Hey guys! I really need some help.
I'm trying to install some larger rear-fill drivers in my '99 Subaru Forester. I want to put some JL VR-600 (6.5" mid-bass drivers) where I had previously used stock speakers. I knew they were larger (the stock speakers were 4" or 5 1/4") and I was hoping to just shoe-horn them in with spacers and dynamat. No dice.
I will have to make a larger hole. I really don't want to go out and buy an expensive cordless jigsaw or something as I would probably only use it this one time. Is there some type of saw or cutting tool (non-powered) that can do the trick?
I'm bummed because today I just installed my rear-fill amp, but it has nothing to do!
Thank you in advance!

RG - 25 Jan 2006 01:36 GMT Tin snips ? Crude but they do work as long as you use a proper gasket. Personally, I hate crude stuff like that but they do work.
On another note ... nice choice in components. The VR series is very, very nice. Especially the tweeter, made by Eton I believe. To a large extent they get their smoothness from an underlapped xover setup along with the soft dome. And I do mean underlapped, LOL. But they have been well thought out and work great.

There are electric nibblers as well, but they tend to be somewhat more expensive tools, and the OP was looking for something to be used probably only this one time.

Or depending on the household, there's one in the garage.

Brandonb - 25 Jan 2006 21:00 GMT Also can try an auto parts store like O'Reilly Autoparts or another place that rents tools for one-off jobs such as this.

Kind of a-la-Futurama!

I bought a set of tin snips for the exact purpose of cutting on door panels to fit my 8" midbasses in there. They worked great. Sears sells them separately but they also have a 3-piece set; one for straight ahead cutting, one for right-hand and one for left-hand cuts.

That's VERY encouraging (knowing you've used them makes me feel much more comfortable about this)! I, too, also want to use them to enlarge my front openings as well to accommodate the 8" woofers I bought.

Tony F - 25 Jan 2006 06:57 GMT One thing I forgot to mention, MOSFET, is that the tin snips work great only if you have enough room to manuever them around. They have a tendency to frustrate you more than anything if you're in tight quarters and can't get them or your hands to move around enough to get the best cutting angle. Just something to keep in mind.

One idea when that's the case is instead of making a round cut, make several radial cuts around the existing hole, then bend the metal "tabs" down to open up the hole. Just be VERY careful of the sharp metal edges.

One other suggestion: the deck where you're mounting will probably be pretty uneven, especially with the cutting; pick up some stick-on foam weatherstrip (it's like that sticky foam tape, but thicker) to run around the back of the speaker flange, to ensure it seals properly to the deck.

Holy smokes, that's a REALLY OLD email address... I don't think ship.net (or at least THAT ship.net) has even existed for about 10 years.

[quoted text clipped - 8 lines] > avast! - copyright (c) 1988-2005 ALWIL Software. > http://www.avast.com MOSFET - 26 Jan 2006 23:30 GMT I just bought and used a new set of tin snips (with kind of a curved blade and leveraged handle) and it WORKED PERFECTLY!! It was like cutting construction paper. No problem. I used some Dynamat around the edges before mounting and then I used some more over the speaker edge once seated to be sure I had a good, air-tight seal. I also used Dynamat to seal all the holes in the sheet metal in the door (to try and create as much as possible an airtight enclosure). I don't know if this helps much but as I want my rear-fill to really pump out the midbass and bass tends to be more susceptible to cancellation, I figure it can't hurt.
Thank you all for the tips!!! My system has NEVER sounded better!! I have NO DOUBT this saved me time and money!
