    Avant front door speaker pods

    Has anyone purchased any front speaker door pods for the front door cards like from jehnert or poket? I've just wired up the Mac-stealth 8inch sub and the front doors are driving me crazy with all the vibration in them. I'm going to take the cards off this weekend and double skin the inside of the doors with dynamat extreme to try and get them under control but the 5.25 rainbow components i've fitted are too much for the door card, they need stiffening up in some way and the plastic speaker adaptors are rubbish. The stealth sub is fantastic - goes really low and really shows up the front sound stage. encourages you to turn up the volume but the fronts need sorting, anyone got any ideas?

    id start by replicating the adaptors from either mdf or birch ply to start with
    then id make sure they are very securely fastened to the doorcard
    be carefull where you add dynamatt on the door card to stop the rattles you need to add mass to the door card to stop it from rattling and to give the speaker some weight to move against but if you add too much the rattles will transfer easier and make the whole card vibrate not just the speaker
    there is a product on the market which is good for this purpose its called
    dynaliner and you simply add this over the top of dynamatt the cheaper alternative is to use box carpet on the inside of the door to stop rattles being transferred to the door itself and then being amplified by the enclosure

    thanks - the trouble is the adaptor is quite tricky as the screw mounts appear to be offset and my carpentry/mdf skills are limited. I was thinking that something added to the front of the card would help stiffen it up, may also allow 6.5 inch components, and as mounting from the front you might be able to add a strap from the inner door (what there is of it) to the speaker pod to stop the card moving and give the speaker something to react against. If i could get an mdf adaptor as you suggested, i would try that first as that would certainly be cheaper and would be worth trying. I was only going to dynamat the inside of the outside door skin and add just small strips to the door card. Do you know anyone who does mdf adaptors? I'm reasonably handy but lack of carpentry skills/tools is the issue. Thanks for the suggestions, the good news is the sub sounds great even though its still running in! cheers

    there are several companies on ebay which produce mdf rings but i do not know of a company which specifically makes an mdf adaptor its something ive allways made there and then if you like
    ive kept a few of the templates ive used for vag cars for making mdf adaptors but the only one i know i have for the a4 is the b6 model not b5
    the one ive done for that is 50mm thick !!!
    only other thing i can suggest is a specialist dealer to do the work for you
    im a little too far away me thinks

    50mm thick - wow - definately wouldn't be much room for a speaker in the B5 but would certainly give it something solid to bolt on to !!! Thanks anyway, where are you in the country? cheers

    Are you amping the fronts? If so as an interim solution just engage the high pass filter and set it at about 120Hz, this will reduce the bass going to the fronts. With the A3 stealth sub you have to set the bass on the HU at -2 to -4 to reduce the frequencies going to the feeble cabin speakers. It really does clean up the sound. I know it leaves a gap between the sub and the mids but it's preferable to distortion.
    Let me know next time you're down & I'll make up some MDF adapters beforehand, just need to whip off the door card in my B5 and make a couple of copies. I've got the same Rainbows fitted and it is a pig to fit as the door card aperture is angled upwards, but the offset mounting posts are at 90 degrees to plumb, so the fitting holes have to be angled to accomodate. Whatever you do will be a compromise unless you go with full on custom door builds.

    that's really generous of you Andy, if you could make some mdf adaptors i would be eternally grateful. I can come over anytime. If you want i can take off one of my doorcards and maybe you could use one of the plastic adaptors as a template if that would help rather than taking off your doorcards? I've fitted another bracket to the sub box towards the bottom front and the sub box is rock solid, no rattling or vibration at all, really pleased! I'm amping the front speakers once the're under control, the wiring is run so can switch over anytime. I'm currently in the boot trying to work out all the red plug wires. No doubled up wires in it, strange? Anyway wait to hear from you - many thanks as always
