Hi Guys. So i nearly had all my stuff together for a build that i was planning on my Fiat Punto until i crashed it the other day :bigcry:

So now im splitting some of the stuff to re-purpose, for instance i going to do a small build on my Peugeot partner van, as i basically live the whole day in the thing. The Previous owner had a "Professional install" done so i decided im going to do it a bit better than these "professionals"

Heres what we are working with.

Peugeot Partner MK2 Commercial Van

JBL P660C Component set (90RMS @2ohm)
JBL GTO804 8" Subwoofer (200RMS @4ohm)
2x Boston Acoustics GTA602's (200RMS@4ohm Bridged) (100RMS@2ohm x2)

Ok now for the many questions.

Door Sealing

The Big holes....... Are there any disadvantages to just covering them with sound deadening? or should i rather get me some thin aluminium plate and knock it into shape, then cover it with sound deadening? ive taken a photo for reference.



Door speaker spacing

Ok so with the "Professional install" Chipboard speaker ring still in there i noticed the window when rolling it down pushed against the JBL speaker if i held in in there so obviously i need to space it even further out so that the window doesnt make contact. but that has me wondering that if i have two spacers stacked and sealed on each other, will i lose sound quality because i am lengthening the tunnel in which the speaker sits? (for those wondering, yes ill make proper MDF ones)

then came another question as i was checking if there will be enough clearance to the doorpanel from the front of speaker, and after some measurements and looking in the gap with the door panel semi fitted i realized ah hell no! the door panel speaker grille is miles away from the speaker! which made me wonder if sound quality gets lost in the door panel if the speaker does not seal up against the grille?, i mean what else is the foam surrounding the grill for? ive attached a picture of the inside of the door panel with the foam surround. is it a good idea to put some SD strips on the plastic panel also?

so in short..

-Is sound quality lost through thicker mdf spacers?
-Should the front of the speaker seal up against the door panel grille?
-Should i use SD on the inner of the plastic door panel also?



Subwoofer Install

Cancellation?- Im worried about the sub placement in the van because of a thread i read about cancellation in a VW caddy van. ive got a nice spot i want to place the woofer but not sure if it will sound nice there or if i will have cancellation there and crappy bass as the end result of that.obviously with the 8 inch im not planning on pavement pounding stuff but just looking for clean tight enjoyable bass in the van. will it maybe help if i stuff the enclosure with Polyfill?

Placement and box build For the placement i found a nice spot right behind the driver seat that wont obstruct anything and conveniently for me is deep enough for my woofer. so if i measure the liters correctly i can make something nice maybe with some fibreglass and effort here. I also plan to adding some SD where ever i can without going ***** to the wall inside the tinny cargo area. any input and tips are appreciated obviously

also attached some pics of the subwoofer and also the place where i want to mount it.

Planning to go sealed here.





The Tweeters

So should i mount stock or make a mod? unfortunately i dont have vast experience in what tweeter placement sounds good but thats why i have you guys right?! the stock tweeter locations seem to be firing upwards into the glass. i suppose the idea is then that the glass reflects the soundwaves to the person behind it OR peugeot could not give a **** where it is, as long as it has a place to go? regardless i dont know how they will sound because there are no tweeters under the covers anyways haha.

If you guys think i should mount the tweeter in the a-pillar, then could you please give me a nice link with some fabrication tips for such a thing? also took a pic of the pillar for those interested.







Thanks for taking the time to read through my thread and i will appreciate any input and advice from you guys. super excited to start this build so ill definately keep you up to date and share pics as i go along. but before i start i would like some advice from the REAL professionals on here ofcourse so. keep em coming!
