I think my subs are out of phase

[Zayne]

So I got a crossfire c7 d2 15” and a skar evl d2 15” and there hitting opposite of each other is there a way I can fix that?

It's a mistake with the subs wiring, typically one of the subs has inverted polarity with respect to the other one, just check a wiring diagram to find out what you did wrong.

I got them wired in series

Even if they are wired correctly the differences in the 2 subs

can sometimes cause timing and acoustic misalignment due to the response differences.

Realize this is a reply to an old post, but for the sake of those reading this after the fact who may have the same question, if you supply 9v (little square battery) to the speaker leads (disconnected from amp) both subs should push out and stay out or pull in and stay in while the battery is connected to the leads.

This way you can visually confirm their polarity is the same or out of phase with each other.

Hope that helps!
