amp keep cutting out/overheating?

[nathanVY]

I'm running a kicker IX-404 and up until a few weeks ago it would seemingly overheat when it got hot, or on long drives. now it cuts out when you go past a certain volume.

any ideas?

[Luke0011]

seemingly overheat? How do you think it overheats by touching it or by the sound cutting out. Ok so now it cuts out when you turn it up, what speakers are they running. More information please.

[nathanVY]

previously when it "cut out" It was very hot, and there is no airflow in the boot. usually had to turn it off for a while and bring it out into the cabin with the aircon (not secured yet)


i'm running 2 sony 6x9s and a 15"" sub off it. stock speakers in the front but theyre powered by the head unit.

is the yellow light flashing when used? (low voltage) bigger cable needed
Thermal cut out is for when you drive it hard and under-voltage
might not be tuned properly is my guess
sub should be on Low-pass (LP)
6x9s should be on Full (AP)

i think the earth and 12v cables are 4 or 6 gauge. pretty thick stuff. the light is green, goes yellow when it cuts out. sub is on low pass in paralell mode and I have one set of RCAs running into the left channel which is the 6x9s and the right is the sub.

THIS AMPLIFIER IS A 4 CHANNEL AMP.
WHY DO YOU HAVE THE SUB-WOOFER IN PARALLEL MODE?
WHY DON’T YOU USE THE BRIDGE MODE FOR THE SUB-WOOFER
AND USE THE 2 CHANNELS THAT ARE LEFT OVER FOR THE 6x9S
THE AMP SAYS IT IS A 2-OHM STABLE AMP BUT WHEN YOU PUT IT IN THIS MODE
IT WILL DRAW MORE POWER AND GET HOTTER

wow caps, parallel mode seemed to work?

how should I have it wired/configured? can you explain bridging?

[PRAVX II S]

If you look at the part were you hook up your speaker wire there should be positive and negative for the speakers
ok now it should say also which positive wire and negative wire should be bridged if you want the bridge mode
and there might be a bridge switch on the amplifier flick it on if you got that set up on the speaker wire section.

Like this.

[PRAVX II S]

like this.

yep thats right just like this diagram.

[PRAVX II S]

FOR SUB-WOOFERS YOU NEED COMBINE THE LEFT AND RIGHT SIGNALS FROM THE RCAs.
THIS WILL SOUND SO MUCH BETTER.
THAT’S WHY THEY MADE MONO BLOCKS

[nathanVY]

sweet thanks so much. I get it now, ill try changing the wiring around and see how it goes.
thanks again.

no worries bra

[nathanVY]

i can't quite read some of the text on that diagram, do you have a higher res one?

Ok read the forum rules, no caps.
I dont understand why your asking him why he has connected the system in a particular way. Thats why he started the thread because he is obviously not sure why the amp gets hot and cuts out. You are explaining how to connect the amplifier in a confusing, broken english manner.

ok now it should say also which positive wire and negative wire should be bridged if you want the bridge mode
and there might be a bridge switch on the amplifier flick it on if you got that set up on the speaker wire section.

You also dont know how this amplifier works. What is a bridge switch? Ive never heard of one.

Sub woofers dont need left and right signals to be combined. The speaker outputs can run dual woofers and or dual voice coils off an unbridged output.
Um sorry why did they make mono blocks????

[Luke0011]

This ix-404 amplifier is renowned for running hot. But i need to know what the specs are for the subwoofer and that you have 4 rca plugs plugged into the inputs. Is one set the rear speaker output and the other the subwoofer output from the head unit.

This is the manual for the amplifier you have.
Hope it helps

[nathanVY]

right now i'm confused. so what goes where? 2x 6x9s and a sub (which has dual output/bridge things on it)

running 2 rcas from the head unit (only 2 sends on the back) and the amp has a line out rca and i have spare rcas to send that to the unused channel. not sure about the sub.

[Luke0011]

ok what is the model of your headunit and the model of your subwoofer, then once i know that i will tell you exactly how to run and set the amp correctly and also explain why your amp is cutting out.

6x9's should not be set to full range. They cannot accurately reproduce frequencies below 80Hz so why would you want sound inaccurately reproduced in your car? Because you are not educated
enough about the physics of audio and a loudspeakers limitations.

why do the mono blocks have left and right signal buddy
and one channel out?

I got a pioneer amp at home and it has a bridge switch for some reason.
it says when bridged flick the switch so i dont bro ask pioneer why they have it i was just trying to help master
and i dint no about caps bro so sorry
again

[Luke0011]

Because most subwoofer or rca outputs have a stereo output. A subwoofer is a mono device. Its output is non directional meaning it does not seperate into two different waveforms like a stereo output provides. The human hear cannot tell the location or origin from which low frequencies are produced from thus meaning mono.
To make it easier for you to understand because you obviously have no idea is that if you split a left output into both the inputs at the mono block the sound would be exactly the same as splitting the right output into both the inputs.

and please dont tell me what i know and dont know i have done plenty of installs here in sydney and am a auto-elec
you are a installer. not a tradesman. you can try to explain things a bit nicer.
were all trying to help bro

Im not a master, just trying to give people informed information. You are giving generalised uninformed information but hey points for trying. I dont know everything and I do not like having to correct people. Ok well thats for home audio the bridge switch and all i could assume that it is there to utilise the bridging of 2 channels. Unlike car audio amplifiers which i do know about automatically bridge and also some amps internally bridge to output the same power regardless of loading to the amplifier
