amp problem

[mightytexn]

I have a Jensen 500 watt amp and occasionally it will go into protect mode for a while than come back on after maybe 5 minutes...any idea why it would be doing that?

they usually do that when they over heat or something, try turning the bass down just a little bit and see if it keeps it up.

Turn the Gain knob down a bit.
Sounds like your putting to much stress on the resisters.

did you bridge the amp? because if you bridge the amp, it changes the amount of ohms, and if the speakers are diff ohms, it will shut off after awhile.

lets get fancy with it why don't we

another question!! if you shut the car off, then on does the amp work again?

[Tony]

that amp should be able to take 2 ohms, i had a 300 that was running at 2 ohms just fine. Im sure its just the amp over heating. Make sure its got plenty of space to breathe, and turn the gain down a little bit on it. Should be fine if it lasts for 5 minutes until it kicks off.

The amp is bridged to 2 ohms, but that is what the sub runs at so being bridged isnt the problem....i thought it might have been overheating but wasnt sure...there is a bass knob and a power knob....which one should i turn down...they are both around 3/4 up now.

[Tony]

yea, probably over heating, just turn the power down a little bit. What sub do you have it hooked up to. a 500 watt amp shouldn't be overheating that bad. but just try turning down the power just a little bit. If your head unit will let you, turn it down there, but that is only if you have a sub output on your head unit.

I have a kappa infinity100.3se 10 inch sub hooked up to it....there is no sub out on the headunit though...i just have a crappy pioneer headunit

Get rid of that piece of shit! Gensen amps are the crapiest amps you can buy! WORSE than the Xplode series.

actually, i HATE sony xplode ANYTHING,......BUT my el-cheapo 250 wattX2 channel amp puts out 800 watts per channel when tested, and it has worked flawlessly since the day i got it, its not one of those shitty ones that is shaped like an "X" on top, its really nice looking, i'll get some pics up if anyone wants to see it

[1990civic]

sony is a good boom for your buck!!! there is nothing wrong with sony xplode at all. infact they make really good stuff for the price, now if you compare it to fosgate well then theres a big difference, but theres is also a big difference in price also!!

2ohm mono and 2 ohm stereo are two different stories. Almost all amps will handle a 2 ohm stereo load with no problems, but a lot of amps that aren't competition series wont handle a 2ohm mono load. Lets say your speaker is DVC if you hook it up parallel both voice coils and bridge it on the amp, you have a 2ohm mono load and the amp might shut off. Try hooking the voice coils up in series and run an 8ohm mono load or better yet, run a 4ohm-per-coil stereo setup.

I used to have that same problem wiht my lightning audio amp. It was bridge and i had it all the way up untill it got some distortion and it was just mounted on the trunk floor and alwasy overheated. But then i mounted it to the back seat in the truck now it has enough room to cool off and its out of the way of anything else and it looks professional.
