I was just wondering if theyre are any downsides of subs facing up towards the rear deck...I have heard that you can get some sag over time is this true? I dont think it should make much of a difference in sound...

 

Face the sub towards the truck so when it hits it bounces off and back towards the car.

 

Thats what I would like to do but space is an issue..

 

What size sub is it? single or dual I had a single type-r pushed it to one side and it was fine

 

2 JL 13.5" W3's

 

Yeah your not going to have a trunk no more. That's why I went with 1 sub.

 

I was thinking just using one of them but I already have 2 I figured I would try and work something out...I got them used at a decent price...

 

I havent seen anyone do this... But what about a suspended box? t triangular shape hung from the deck lid would put the sub aimed in a good position... Just a thought it would give you the most room possible.

 

My buddy did a custom thing in his trunk where the sub is were the spare goes and is level with the mat. saves room and is sick. just gotta cut a piece of wood the size of the trunk

 

I have seen that. It looks ok and sound fine. you could do a plexy glass cover and save all your trunk. Hope you dont get a flat )

 

low frequencies are omnidirectional. remember that...

 

true but cancellation is very imminent. ultimately it depends on if u want to sacrifice sound for space or whatever (the physical space is the same) facing back will be the loudest. up second and forward last. keep that in mind and if you do face them up dont blow them

 

well i went with a custom memphis shallow 12inch dual 4 ohmn speaker and amp and i faced it towards the trunk in other words against the back of the seats and its loud as hell for a lil 12inch didn't think it would sound so loud and have the bass only half way and bass low on the radio settings and it thumps and i still have bunch of room in the trunk will take pictures.
