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.

get a DMM and check the impedance of each channel  you have hooked up...

 

 right off it sounds like you may be running it below its ohm load threshold

When you say "check the impedance of each channel  you have hooked up" what do you mean? I am sorry for being a noob. English not being my first language doesn't help either lol.

Do you have 1 speaker hooked up per channel?

[jonbearsmt 919]

 get a digital multi meter and select ohm mode, and check each channel and see what it says.. 

 

 do you know what each channel should be running at?

[ricksi30 923]

Well I should rephrase, one tweeter and mid per channel?

Right now I don't, but the amp's manual should say right?

I have 2 fronts speakers + 2 rear speakers (with tweeters) bridged into 2 channels.  Then the sub woofer bridged too.  

[jonbearsmt 919]

 there is your issue.. it sounds like you have the 2 channels ran at 1 ohm mono...

 

 how is your sub wired?

 

 im not familier with the boss amps but i doubt it a 4 channel 1 ohm stable

[ricksi30 923]

So you have two component sets hooked up to two channels bridged <<<(probably the issue)? Then one sub hooked up to two channels bridged? What subwoofer?

2 ohm per channel and I would say that is the issue too.

[jonbearsmt 919]

it would be 2 ohms stereo .. but he has it brided 4 4 ohms speakers in mono  is 1 ohm

[ricksi30 923]

it would be 2 ohms stereo .. but he has it brided 4 4 ohms speakers in mono  is 1 ohm

My bad I meant the amp is stable at 2 per channel.

CH 1 & 2 bridged for speakers  and CH 3&4 bridged for subwoofer

[jonbearsmt 919]

 first things first you need to unbridge the channels running your front and back speakers.. you can run them 2 ohm stereo...( two speakers on each channel)

 

 and the amp shows to only be  bridgable at 4 ohms.  so we need to work out that sub issues too.. waiting for the modle and impedance of the sub to work that out..

 

 

 here are the specs on the amp

 

Max Power Ratings

• Total Power: 2400 Watts
• Max Bridged Power @ 4 Ohms: 1200 Watts x 2
• Max Power @ 2 Ohms: 600 Watts x 4

 your  picture shows other wise

[ricksi30 923]

Yeah what do those wires go directly to? Where are your speakers wired together? I'm referring to ch 1 & 2.

I think I explained my self wrong in the beginning. I am sorry for that let me try to give you all the info in this post. What I've done is CH 1 is for both Left speakers (front and back) and CH 2 for right speakers (front and back). Then, bridged CH 3 & 4 for the sub.

Those speaker wires go to the front where the original speaker wires were when the car had original Audio System. What I did is, I bought a connector to avoid cutting the original wiring, so those wires you are talking about they go to the front and then I matched them to the original (factory) speaker wires.

ok 1  and 2 are 2 ohm stereo...

 

 whats up with the info on the sub???

What info do you need from the sub? I will try and get it for you right now. 

[jonbearsmt 919]

mainly  if its dual or single voicecoil and what impedance it is.. dual 4  dual 2 single 4 or single 2

[KeboPR 0]

Its single coil and the impedance I will try and get the info right now. Also, I will take a picture to the gains and frequency so you can tell me if they are right or not. 

[jonbearsmt 919]

also list the setting on the head unit.

also list the setting on the head unit.

 

I don't know if you can see it but if you turn brightness up you will see it.

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