trunk sub considerations

I was wondering what I should take into consideration for a sub in the trunk of a 94 accord.  I'm putting a 10" brahma in a ported box back there, but I've only dealt with trucks and suv's.  It's my first "little car", with a trunk.  Just curious about how the trunk will affect the sound.  The box is .86 ft3 @ ~29.5 Hz.  I wanted it to pound but sound decent.  Thanks for any info.

Be prepared for major sound deadening! I still haven't got enough in mine. Depending on where you mount the amp, you may find that "venting" the rear seat will produce better results. I'd go in with a hole saw and pull back the carpet and remove some steel.

Put that box right up against the back seat, fasten it down with brackets and aim it towards the rear. Be careful when mounting it as the fuel tank and linkage are right below the strut towers.

By venting the rear do you mean cutting holes in the seat?

Yes. the fold down seat has a metal plate on the back of it that decreases volume. I wouldn't cut it out completely but some holes in it will make a difference.

You'll have to expose the rear parcel deck for damping purposes, too.  Look at it and you'll most likely find speaker cutouts that you can use for opening the trunk into the cabin.  If there is a middle one you are good to go.  If there are only the left and right, and you're using those for rear speakers, enclose them in hats so they won't distort too bad with all that pressure coming from the trunk.  In the middle between them is a good place to cut a hole.  Build a "tunnel" from the trunk to the inside of the car, and finish it off with a grill.

Here's how I did my Taurus

I used a piece of flexible air duct and two hats (bottoms cut out and one inverted over the other) to form the tunnel.  That keeps the air pressure from affecting the speakers in the rear deck (not seen; hidden under the carpet...OEM look).  A grill painted to match the interior.  So it looks like it could pass for the OEM subwoofer grille because that cutout is where the OEM sub would have been.  Under 200 watts of subwoofer gets very LOUD in the cabin.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

thas nice stevdart, in my wifes taurus i used the stock 5X7 holes and grills. but the dang grill pops off sometimes when she turns it up.    it dont look near as good looking as yours. its just a temp system since shes looking to buy something else.

This grill came with a rubber ring that is around the edge, covering up the screws.  I popped through the pasteboard and used small machine screws with washers and nuts on the other end.  Stays put.

Thanks for the info and pics.  Nice setup stevdart.  So I should cut out some of the rear seat and use either the holes from the rears or a new one? Or is it one or the other?  Thanks again.
