WHAT IS THE PHASE SETTING ON AN AMPLIFIER?

The Phase Setting on an amplifier is important for balanced air pressure in your vehicle. You see builds all the time with both inverted and standard mount subs in the same space. Depending on how your subs are mounted, you want to manage the air pressure that comes from your subwoofers and prevent it from building in your space.
In this video, JP gives us an explanation on why the phase setting on an amplifier is important.

JP thanks this was very straight foward information.

[DavidHopkins-jynn]

So if I have 2 12” subs in a 4 th order bandpass what should my phase be set to

[PrydeWater]

Thanks for the info, however, more may be needed. This explains the phase setting of it is a switch. If the phase setting is on a knob which variable from 0-180 degrees…

[midwestbass]

I've always just bypassed this setting

[walkingfreak]

I don't know why i never thought of utilizing the phase control on an amplifier with mixed subwoofer mounting. I gave myself the brain ache of wiring them different so the phasing would be correct on all 4.

[________GHOST________]

I only use that when I am using 2 or more subs. But I never use it on a single sub.

[philipeli]

If you have door woofers running on a head unit this control will allow you to phase it to the subs, it will produce a more solid sound than 180 out. So I respectfully disagree that it doesn't matter which way its set, you can simply hear it.

[rodneyrod]

Phase is to match your main speakers to your sub, distance player a big part. Also ported vs sealed player part.

[Chromedome-ssmg]

Couldn't you just wire the two subs upside down, backwards. (Reverse polarity)? That's what I always did

[bigmike]

Hey I have that amp but I want to kno am I able to get the outside I guess restored I bought it from a friend but it’s outer shell is dull and has some scratches on it

[perfectlyimperfected]

So if U have 2 r inverted an a 2 r standard mount with out using the phase controller.. your subs r more or less canceling each other out ..

[GhostDust]

i’m still a bit lost lol. i have 2 subs both facing the same way and in same box so the shop should of just left it zero basically ?

[justforlaughs]

Not only that if you have two amplifiers that are the same what say you have 1 amp on one set of woofers and another amp on the other set of offers and they're both faced the same way some amplifiers will still not be in the same phase you would see this by hooking them up to a oscilloscope that has more than one channel and you will see they will be out of phase and you adjust the phase on 1:00 amp until they match each other Sam on YouTube barevids shows this in a demonstration

I got a question so I got 2 12s 2500 watts & 1200 rms what rms should I look for in a amp & what size wiring kit should I get ?

[NapilihauKreationz]

Strapping any version jp23 amps, will they be good to push a 12 nsv5. Also would it be louder to run 2 zvx 12 or 1 nsv5. Thanks

[reaper]

How do I get that awesome customer service you always talk about from d4s because that hasn't been my experience ?
