back to back, as in magnet to magnet? the magnets together would interfere im pretty sure, idk why you would wanna do this and i wanna see the box your doing it with //content.invisioncic.com/y282845/emoticons/needpics.gif.edd6d28e76618c28c46f343991bcced5.gif

and when you say back to back or are you talking about cone to cone?

I'm very limited on space and theres no pictures cause i have not done it yet its just the only way i can fit 2 12s in my truck

im refering to putting to subs in at an angle like /oo\

o being the magnet and \ being the cones

how much space would you have between the closest point on the magnets?

im pretty sure you dont wanna put them too close have a lil room.

im trying to fit 2 12" L7's in my truck and it would be a huge task just to fit 10"s im talking a full fiberglass console just to hold 2 12"s

hhm after thinking about it i could do Cone to cone with about 5 inches inbetween them but i would prefer to mount magnet to magnet if i could figure out what distance is safe to do it like that?

Could you just go with one 15"?

 

[Bagged96Chevy 10+ year member]

no not without removing my rear seat and i really dont want to remove it ...

i dont mind making a console that crouds whoevers sitting in the middle but i always end up with more than 2 people in my truck

There's no problem with the magnets very close together, the motors are typically set up so that the magnetic path is in saturation (it as "magnetic" as it's going to get), another similar strength motor near by cannot effect it.

you could face them towards each other and wire one out of phase so that one sub fires out as one goes in. dont know how thats gonna affect sound though

Or you could just use one sub........................

Volenti thanks you actually get what im doing here lol are you shure it wont damage my subs or effect the sound quality?

This is a simple push-pull configuration, and you will still have the same space issues, and lose 3dbs.

if you do isobarik loading, you'd only need 1/2 the volume for one woofer then for both. This might actually help u get them both in your truck, or get smoother roll-off if you've got ur box built already. But you'd still lose 3dbs
