Inverted subs

[Destram]

you can mix them, just need to swap some wires around

No, I'm saying I wouldn't do it personally. I would rather them all be inverted or all normal.

Can you invert subs with a head unit that does not have the setting to do so?

yep, like I said, just gotta switch some wires on the subs around. the H/U he has just switches the phase of the signal before the amp, meaning you don't have to rewire your subs

Does inverting them raise or lower the tuning of the box?

[raytard]

technichally it lowers it, but its not going to be a whole lot. maybe with 4 15's you'll drop tuning 3-5hz.

there is no sq difference (unless you have a woofer with a lot of mechanical noise) and output stays basically the same (maybe a tenth or so, in theory there shouldnt be any difference since the radiating area stays the same, but whatever)

Thanks for the info. I'm going to give this a try in the next few days and see if I like it.

Just to clear things up:

I have (2) 12s and all I need to do, since I don't have the setting on my HU, is reverse the negative and positive?

not sure if its been answered.. but on some amps they have a phase switch.. it should say 0 degrees or 180 degrees.

Hmmm...I don't think my amp has that option. It's pretty crappy.

i assume its a 1 channel ?? in that case just switch the wiring from + to - and - to +... although you could just play it as is..... but.... wouldnt

It's a 2-channel amp but I have them bridged like this:

Sounds like all I really need to do is switch the + and - right at the amp.
