Amp goes on PROTECTION MODE

[Super318ic]

I installed my 2 12s today in my car. When I turn up the volume too much the AMP goes on to protection MODE.. why does it do this.

Possibly it is not 2ohm stable and when running two drivers you are at 2 ohms?

[Jordan]

Too low a load, not enough current getting to amp, too much voltage drop between amp and battery, could be alot of shit.

Give us details about your system, its all but impossible for you to be ANY LESS SPECIFIC then you have been.

[Super318ic]

I have 2 12inch Infinitys with a Saat Amp(MTX)400watts.

[Jordan]

great, BE MORE SPECIFIC.

what kind of wiring are you running? where are you grounding to? etc...

[KenC]

Are you paralleling the subs and then running them to a bridged amp? My guess is that the amp can't handle the low impedence.

[Super318ic]

4g wire, Grounded to the ground of the trunk.

You have (2) 12" Subs running off one 400 watt amp? Of course something isn't going to work, for one 200 watts per 12" I'm guessing wouldn't really push them let alone make them thump. I had a 250 watt amp trying to power a 12" and it just didn't work. I'd suggest using that amp for your speakers if possible and buying a bigger amp.

Thats not the problem. They power it fine and it has LOTS OF BASS. Only thing is when I turn up the volume to much it goes on protection mode. And 200watts will still make bass for a 12inch. It

200rms is plenty for a 12", you have no idea what you're talking about. Furthermore, the amplifier would not going into protection mode if there simply wasn't enough power for the speakers. In addition, when you ran a 12" sub off of your 250watt (probably Power Acoustik), you must have improperly installed the amplifier for it "just not to work."

[KenC]

What are the technical specs for the amp? How do you have the subs and amplifier wired? You're probably running the speakers at an impedence below what your amplifier can handle.

[Super318ic]

Well I just found out it only does this when the car is On. When the car isnt on, it works great and REALLY LOUD

My 250 watt amp was a pioneer , I'm not assuming anything. Just throwing out some information I've witnessed. It didn't do anything for my 12" sub. I didn't wire it wrong, it just had no punch, barely going. That is all I'm saying. Remember, I'm just trying to help him solve his problem aswell, no need to try to put me in the wrong. I just would think the Infinity's would like to have more then 200 watts rms going to them, and maybe the amp wasn't able to push them. Speculation.

It wouldn't go into protection mode if the amp couldn't power the speakers. It'd just clip until the speakers blew.

I think you should probably take it to someone who knows what they are doing before something gets screwed up. You won't get warrantied a new amp due to negligence on your part for hooking it up improperly.
