I have the Alpine Spx 177A 6.5 components I was wondering what would be the best thing to enclose them in.
1) factory location in door with back open.
2)Sealed fiberglass enclosures.
I thought to get any kind of midbass I would need to put them in sealed enclosures but I came across some people that said components are not ment to be in sealed enclosures.
You will be just find be putting them in the factory location or in some kickpanels, If you put them in the factory location you can put a dampening material on the door before you put your panel back on this will seal the components good enough and keep road noise from comming through the door

Almost all components were not meant to be in sealed enclosures. Sealing them in a small kick panel WILL hurt their midbass performance. If you have a dedicated midbass driver, go for it.
Door location is fine, midbass will be better than in the kick, but you'll be more off-axis and midrange won't be quite as good.
It is a game of trade-offs.
I'd shoot for the kick. Put some Koda 6 midbass drivers in the door. Cross the Alpine over at 300hz high pass and seal a kick panel up. You'll be rocking.

I already have two layers of b-quite extreme on my front doors but after looking at the stock location the back of the speakers would be open to the whole door which is not really sealed since there is that slot the window goes up through. So I built fiberglass speaker pods for them but the midbass sounds a little too tight alomst like the enclosure is too small. I wanted to redo them to try to get them close to the internal volume suggested in the manuale plus I want to make them fit in the car a little nicer and not stick out so much. This was my first time using fiberglass I think if I redo them they will come out a lot better.

kfr01 I noticed you have a Xtant 4004T, I justed picked up a 6001T and I have been looking for either 2 2002T's or one 4004T to match my 6001T for my interiors any suggestions. I am using a older xtant 404m right now.
I came across this article in car audio magazine this guy used the same components that i have and sealed them in a .33 cuft enclosure so i was thinking of going by that internal volume.

pjoseph, lurk ebay for a few weeks. They'll show up, it was a popular line a couple years ago - lots hitting ebay now.
I've been very pleased with both the 4004T and the 2002T. Great quality and honestly rated power for the price.
If you really want to know the answer put the T/S parameters into an enclosure modeling program like WinISD pro.
