so after about 5-10 minutes of listening at high volumes (greater than 50/62) the amp going into protect mode until i turn it down for literally 3-5 seconds and then it comes back on.....

i checked my manual for the amp and it says:
-speaker wire may be short circuited
-speaker output contacts ground
-unit malfunctions and a DC signal is sent ot the speaker output
-internal temperature gets to high
-ground wire of the center unit or amp is not connected

i checked my ground and it is good, but on my headunit wire harness there was 2 grounds, one on the aftermarket harness and one on the radio... i only have the one from the harness grounded, but everything is working.....

my speaker wires are good and brand new

the amp gets a little warm to the touch but seems ok

speaker wires are not contacting ground or vise versa

so im only left to that one ground wire, or a DC signal... whatever that is

 

when that happens to mean it means my sub is blown lol.

 

that means that either you have it bridged down to low..... or ..... well that should be the only reason if everything else is good..... what kinda amp?

 

It could be the radio. Play it too loud and it starts to clip.

Dose everything work fine when its turned down?

 

no when i have it loud the subs do not distort or clip, and they arent blown because the amps power light turns off but this blue light stays on which means it goes into protect mode

the amp is a kenwood kac8104 mono, i have it wired at 2ohms, which it is stable at

 

turn down the gain. is the amp hot to the touch? your hand is warm so when you touch and its warmer than your hand, may be overdriving the amp. how many subs?

 

2 subs, gain is in between 3-4.......

 

They might not distort or clip b/c the amp catches the clipping before it gets to your subs and sends it into protect. I know at lower ohm loads that amp doesn't perform well, even if its within its recommended loads.

 

so what should i do?

turn the gain down?

try grounding that wire.... idk

 

amp is tuned incorrectly

 

so how do i tune it................... aha help me

 

Try turning down the amp a lil bit. That ground wire is off the radio chassy or what?

 

check how many ohms your running you many be running to low ohms for the amp or to many for the amp

 

no im wired at 2 ohms and the amp is stable at 2ohms

 

are you running a fuse or is it direct to the amp maybe your fuse melted it happen to me it mannage to keep playing but any that moved it a lil amp turned off lol

 

idk man, i can go check

my amp has a fuse and i have an inline fuse

 

Sounds like you got a bad ground to me and if you keep putting it into protect mode one day it will burn out. Try grounding it to something else.

 

maybe it melted youll be surprise how many times fuses melts without you knowing lol

 

where would be a good place to ground it?

any bolts or something back there, i have it right now on that black bracket holding down the rear seats

i think im going to try grounding it directly to my battery...... if that doesnt work, i guess im out of luck

 

ground strait to the battery its the best.

 

yea thats probably what is it, the ground cant keep up with the power at high volumes so it goes into protection to stop from overheating and blowing

then after a few seconds it cools and comes back on, then i turn it back up and it does the same thing

 

where is it grounded now and did you take any paint off when you grounded it? If not then that might be the problem.

Let us know

 

the black bracket isnt mounted/welded to the car so even taking off the paint isnt going to do anything. theres probably more resistance in that ground then you can imagine. im sorta surprised it even really works

 

^^ thats true.

You should go to the battery for the ground

 

I had a system years ago that used to do the exact same thing. I'd crank it up, bump for a few mins and it'd go into protect. Does your amp match/exceed your sub ratings? Cuz my problem was too much of an under powered amp for the subs. Put in a new amp with higher power and never had the problem again. it's always better to turn an amp half way up to power the subs than to max it out and only half power your subs
