New Amp and sub magnets getting super hot

[95lincdog]

Whatever your tuned to multiply by .75 and set it to that

Tuned as in voltage reading when u set the gain? Or what ur box is tuned to? Sorry I'm a noob. Also my HU has a frequency setting. It's set to 80hz right now if that matters

SS should prob be in the lower 20's,30's... If set at 80hz then you got some big ole mids back there...

Man, the dude at the stereo place set it at 80 and made a point to tell me always 80. Dammit. What should it be at? The lowest option is 65hz

U need to go buy a DMM an do it right.. Start at the amp first then go from there.. Must not be your SS filter cause it will be much lower than 65hz.. SS should be in 20'2 30's depending on the tuning of the box. Your LP filter should be set based on your box but 60's a round number.. Gain needs to be done using instruments not pics. So cant help u there.. BB needs to be off also 0db on amp...

Thats not the subsonic filter, thats the low pass filter. Sub sonic is even lower

Just so we are on the same page man.

From right to left the knobs are :

Gain adjustment, Subsonic Filter, bass boost(leave off at all times), Low pass filter, Phase switch

Turning left is minimum right is maximum, Gauge where it might be 25-30 on the subsonic filter and just leave it there. Low pass filter leave it pretty open to 150 or something since your head unit is already taking care of the low pass filter. phase switch leave at 0.

Go to your head unit, TURN OFF ALL BASS BOOST, LOUDNESS, BASS EQ options. Only thing you should use is the subwoofer level (max that out) and the volume knob to get bass out of your subwoofer. Then play your heaviest bass song, go back and readjust the gain, if it stops getting louder, or sounds distorted, then turn the knob back a little bit.

Head unit high pass filter and low pass filter should be kept at 80hz, its fine there.

And this folks is why a "shop" never touches my ride, EVER, for anything.

The only thing I can't rebuild is a rear end or a *****.

That amplifier is a current model, and Phoenix Gold is sold through brick and mortar dealers only. You may have bought it second hand, but if you bought it new you need to let the shop handle this.

Is it possible my amp and magnets could be getting hot because the amp is too powerful for the subs? Amp is 1200 rms and the 2 subs are 400rms each??

I set gains with a meter, I tested voltage at the amp while volume up almost halfway and it never went under 12v (there's no number after the decimal).

No, only the sub will struggle if the amp is too powerful for the subs and you well definitely tell when the subs starts to struggle because they will bottom out and sound nasty. Amp should stay cool.

You need to test it at full blast. Also what brand of wiring are you using? is it copper clad aluminum or OFC? How good are your grounds? Amp getting hot is either a clipping issue due to bad signal or clipped via lack of current.

My power wire is kicker ofc. And my ground is JL audio ofc. The ring opening on my ground wire is bigger than the bolt that goes thru it. I put a washer on it. I'll try to find a different spot with a bigger bolt

is the ground sanded down and directly on body chassis or strut tower?

I didn't sand the ring. The spot on chassis was sanded

Re-sanded the ground wire ring and chassis, put a bigger bolt that fit the ring more snug and amp is doing fine. Thanks everyone. Magnets still getting a little hot, but I'm guessing its because they r 400rms each (2 subs) hooked up to a 1200w amp
