Subwoofer Project FINISHED!!! (Enclosure Dimensions Included)

[Essam Khafagi]

Philly X5 and X5-limo ... what's the progress? Anything installed yet?

Hmm.

I might be busy this spring.

I have amps and speakers galore sitting around. I haven't done anything audio related in awhile. I've just been collecting parts from all of my past cars.

[Essam Khafagi]

well, everything is back in place ... the rattle disappeared and the door closes like magic

BUT

There is a lot of rattle when the door is in place and it is coming from the door plastic lock!

Final decision ... no door as long as I have no cargo
Door in place when I have cargo and the bass level should be reduced a bit

[sleepless]

what if you install a L shaped bracket towards the top right of the sub box and install a nut and bolt to the hole, like they did in the BSW video ????? this might make the box not rattle against anything .......

That's persistence. Great job and thanks for sharing!

Try to take some thin foam or cardboard and cut a slot in it. Then use it as a gasket in between the lock and the surface. Ya get what I'm saying?

The bolt that attaches the bracket to the box is an ancient VW 10 mm sheet metal screw that is threaded into the MDF. Apply torque carefully! Again, just to illustrate that a bracket is a good solution.

To hold the bottom in, I put door insulation foam peel-off tape on any area that might touch and then some in between that big plastic trunk floor support and the front face of the speaker.

It is all good now on even the deepest sounds, although I do need to put some tension on the access door for those "special audio moments". Heh, heh.[/quote]


.Hey Carlgo....... how did you attach the screw to the MDF ????? don't you think this would come loose since MDF material will loosen up after time.....

[Essam Khafagi]

yes sleeples and jose ... I will do the bracket and the foam thing to the door
it sounds awesome now without the door

.....just got in from a 1-1/2 hour cruise listening to some sounds. I had just finished installing and wiring Essam's box in this -12F (windchill) weather - probably the same where Philly X5 is! Inspite of the frozen fingers and cajonas.....thumbs up to Essam, his box and amp hookup rocks as advertised!!

The installation was as smooth as silk. I have DSP - kudos again to Essam for his help!

There's no way I'm going to put the hatch door back on - No way Jose! The sound is busting out of the amp! I've found some fabric that almost matches the beige interior dead-on, so I'm going either cut a nice large square hole in the hatch door and stretch the fabric over it and the entire door or cut a circular hole and install a grille if I find an appropriate one.

Now, and like Carlgo, I'm going tackle a speaker upgrade to really enjoy the sounds. I'm going to do the F/R midbasses first and then look into the midranges/tweeters (as my $$$ allow).

I found and used the 4-pin connector....it made the installation sweet and simple!

Man, I am jamming

This was a real fun but the system ("Essam Box") is installed now and I love it
I tried several options - with the cover open/close, with the sub mounted on the cover and the best sound is - without the cover. I will be making an opening in this cover and all I need now is some fabric to stretch over the cover or maybe I will make a speaker grill - went to Home Depot and already have some ideas.

X5 limo- where are you getting the fabric Can you share the secret

Also where you got the Alpine connector from?

that shows the 'cousins' that we are - the 'Philly sound' vs the 'MoTown sound'

......don't laugh, but Walmart's fabric department, (of all places!), sells a $3.00, 50" x 70" fleece throw! It's brand name is 'Main Stay'. They are sold in rolled up bundles like mini blanket rolls. If you can't find it, I have enough to cover several hatch grilles.....just let me know. So what design/technique are you coming up with?

I was thinking about just stretching some of this material over a cut out in the hatch door but, thinking ahead, I'm figuring it may be more practical, in my situation, to cover a wire mesh across the cut out as this can help protect the subwoofer from any bumps from future pieces of cargo.

...I think you can order the (4-pin molex) Alpine amp connector from their parts distributor, PacParts, Inc., ask for Melissa Marin, (Customer Service Representative) (800)421-5080 Ext. 154 - (800)782-5747 Fax. It's their 'Speaker Input Cord' - P/N 01E11136S01
