Amplifier goes into protection mode [HELP]

[KeboPR 0]

My amplifier keeps getting EXTREMELY HOT and going into protection mode after 30-45 minutes of listening to music. I bought a 4.4 Farad capacitor to help fix the problem but it keeps happening.. Any suggestions?

I have a Acura RSX 2003 with 4 Pioneer TS-A1604C 6.5 Speakers, Boss PH4.600 Phantom 2400 Watt Mosfet 4-Channel Bridgeable Amplifier, and a 4.4 Farad Capacitor. I am very sure I installed everything correctly because it sounds very good but after 30-45 minutes It goes into protection mode.

Also, I forgot to mention I have a radio JVC KDX50BT which has a integrated parametric. That is why I didn't have to buy a separate one. I don't know if this is of any importance but I am trying to put as many information I can.

The amp gets extremely hot? Sounds like a thermal overload. Too much for your amp to handle. 

4 speakers and 1 sub too much for a 2400w amp?

also list the setting on the head unit.

With settings on the head unit you mean the settings on the parametric for bass mid etc?

If the nominal load is too low.. Yes

That is what we are all waiting on is the DC Resistance reading of the sub.

 

Impedance kept being used in this thread and do NOT try and measure impedance as you could kill a DMM.

 

But i also think he said he doesn't have one.

 

Rule #1- don't get into the automotive hobby without a DMM.

I do have a DMM but I don't know what exactly is what you want me to measure.. Sorry for being a noob but could you please explain?

Also, I have tried with 2 different subs and it still happening.

Take Dmm, set to ohms.  If not auto-ranging meter, then set to 20 ohms.

 

Make sure the stereo is off(i am assuming if stereo is off, amp is off too).

 

Unhook EACH pair of speaker wires(+ and -) and measure the reading on the DMM.

 

Before doing that, touch the probes together for a few seconds to get a consistent reading of.. whatever.

 

If it's anything other than 0.0000ohms, then take this number and SUBTRACT it from your actual reading when measuring resistance on these wires.

 

So, do this with left channel 1, right channel 2, and then the sub wires.

 

You MUST disconnect them from the amp or you will be reading the internal resistance of the output section of the amp which will give us erroneous results.

So what you are saying is to measure OHMS on; + and -  CH 1, + and - CH 2, then + and - in sub (with cables DISCONNECTED FROM AMP) ?

just measure each of your speakers separately except for ch1 and 2 as they are wired together.

oh im sorry the ohmic resistance of the  conductor

 

 i dont think it matters.  he would not have known the diffrance. but thanks

[shizzzon 461]

oh that was you?  No biggy...

 

I can tell he is new to all this so i didn't want him researching these terms to find out this means AC and that means DC and get even more confused...

 

While he should eventually know this stuff, well, i quit, lol.

 

I'm going to sleep.
