Tell us about your sub amp and a web link to your sub(s). Not enough information given in your post, to answer your question.

Amp brand and model # is ?
Sub brand and model # is ?
Is this sub a 2+2 ohm version, 4+4 ohm version or other?

Not sure what you mean by "Phase speaker".... please explain.

Well, if it is 2+2 ohm version U have 2 options: 1 ohm load ( // ) or 4 ohm load ( series ).

// wiring into a 1 ohm load would be working that amp pretty hard and if the amp performs as rated would be too much for your sub I'd assume. <-> Don't // wire that thing!

So I'd have to advise U to run the 4ohm load in Series, theoretically get 600 watts out of it, prbbly less. Even so -
you should be able to have that sub working hard off that amp
at 4 ohms, while leaving the Amp Level relatively low to keep it running cool.

Positive from Amp (bridged mode) runs to (+) on voice coil A.
Then connect (-) terminal of coil A to the (+) terminal of coil B. Now, from the (-) terminal of voice coil B connect to the amps ground.

Series Sums the ohm-load of each coil, and it looks like this:
(2+2) = 4ohms = standard ohm-load.

Amp(+)·······[A+A-]·······[B+B-]·······Amp(-)

Of course, hopefully it wont be a straight line when U actually wire it up...

Enjoi!

Yep, I agree, wiring this sub in series for a 4 ohms load is probably the safest routeto go on that Boss amp.

If that amp is a MONO (1 channel) sub amp, then it may do 2 ohms OK... but few low priced amps can handle 1 ohm loads w/o breaking down.

If a two channel amp, "perfect for a 4 ohm load". Just bridge the amp which adds both channels together and use the 4 ohm load. If you need a diagram on how to wire a sub in series, www.jlaudio.com has a very good set of diagrams regarding sub wiring options. It's in the tuitorial part of the site.
