You should be fine bro only 90 and if they break it's no big deal. If it's just the plastic cone and it's not a deep one then it should be fine.

Does anyone know if these subs can be mounte Inverted?

Like with the Cone facing the inside of the box, because these subs look BRAND NEW from the backside of them

And can i use them in a sealed enclosure like he did? is it safe?

you can invert any woofer. im pretty sure you can use those in either a sealed or ported enclosure but ported would be nicer. it would have alot more output.

I completely agree with kranny ported be best but you can do either

So it would sound louder with ported?

I only have 1 15" in my trunk right now, so either way is gonna be louder

Ill try ported, what should i tune it at? mid 30s? 34-36?

Thanks. What do you think i should tune the box to?

I would say 33 - 38. You will hit more lows obviously the lower you go. It's all your preferences I like around 35

I think ill Invert the subs, and have them facing up, and then ill have the port towards the rear-end of the trunk ..

I like deep bass, but i also wanna be able to hit the little bit higher bass lines .. Think 35~ would be a good freq?

These are the P3's that i have P315D4

Ill upload some pictures in a few hours after i get them off my iPhone ..

The one sub has a Hole in the cone (FTL!)

But these subs look brand new from the inverted position !

[Chamois]

Bump ..

Can these be reconed? Only one needs it though

Haha well idk how to tune inverted I have never actually did one but 35 is a really good tune imo

The only difference is you don't account for woofer displacement. If you want to get super accurate, you account for the added volume of the speaker cone, but it won't make a noticeable difference unless you have a crap ton of woofers.

If you can do sub/port facing the trunk. That's generally the best option for trunk cars. You'll have some vehicles that will behave differently, but most of the time unless you're sealing the trunk and/or porting through the rear deck, sub back, port back is the best option.
