Sub Woofer Installation, Tried to get better Audio without carving up the car Options

[ctc911ctc]

All,

Been silent, very cold - garage is a 100 year old Yankee version, no heat.....will not hold any. So, my 17yr old son and I decided to upgrade the speakers (the old ones were absent any cone material).

Found a set of KFC-4675C (kenwood) that fit the spec, integrated mid range and tweeter. Now for the low range. We decided that carving up the car and running a large alternator and battery was not for this car, we are trying to restore it to 80-90 points. So we are using a passive crossover, the original tuner with a power amp that was installed in the 80s, still works (both units are Blauplunkt). We have about 40 watts - more than enough for the size of the car.

When we rebuilt the car we installed sound deadening material in the engine bay, passenger compartment and will put it in the trunk. Amazing how quiet the car seems in the passenger compartment now.

My son had the idea to install the Subwoofer in the engine compartment, cut through the back seat - had to explain the concept of FireWall to him, we looked at a dozen other places and settled on what I think is a very elegant solution.


Our car is a '74 2.0, Silver. So it has a center console. We are installing it there!



First, where should the speaker go????



Wow - no particle board - furniture grade ply!



Peel back the Vinyl, careful!



Counter sync for flush hidden finish



Score the vinyl, perhaps we can STRETCH it!



Heat gun and PULL, gently



Look at that circle, no wood showing, barely a wrinkle!



Add a screen



Bolt that Micro SubWoofer in place



What the Passenger will see



Perfect Fit



Passive Crossover


Will post a note as to how this sounds in a few weeks (months?)

the best place is to put a sub woofer is where the foam floor board block exists on the passenger side. Totally hidden, takes up no space, sounds GREAT and does not chop up the car. Here is a picture if anyone wants to make one: http://www.autoatlanta.com/Porsche-914-Spe...N-BAA31934.html

It is very easy to make, basically the pattern of the block with a leg to support it. We have made hundreds over the years and the sound is great, and TOTALLY hidden

This isn't an ideal solution. A subwoofer will perform far better in a sealed and ported enclosure. But it might be better than nothing.…

check this thread out.

my sub box that is now sold by 914rubbers is in post 15 and 16/

it's a good tight bass with good volume.

^ THIS is the way to go, or at least the way I'd like to go. The first one shows how the box should be done, while the second and third are more appealing to those of us who want a truly stealth setup. How to the ones where you can't see the subwoofer sound?

And you say they're available from 914Rubber? (IMG:style_emoticons/default/idea.gif)

what do you do to protect the sealed box speaker (lower left) from feet?
