I have a 9152d supposedly it puts out 1000rms at 1ohm and 900rms at 2ohms it is even CEA certified but i put (1) kicker L5 dual 2ohm and wired it so it presents a 4ohm load and this weakass amp clips out...when i set the gain i have the headunit turned up to 3/4 volume and the amp is no more than 1/4 of the way up and in like 2min the amp shuts off and then like 20sec later it turns on...my friend has a 8152d and it does the same thing...i think it the amp but is it????and yes i have it on 4guage and an upgraded alternator and a lightning audio 1 farad cap. what could the problem be?

Your ground? Have you metered your ground?

If the amp is clipping, then you have your gain set too high, even if it is only at 1/4. If it's not clipping, only cutting out, check your subs/wiring with a meter. Move the cones both ways and make sure nothing is showing a short.

My ground is good and when i swap amps to my JBL bp 600.1 everything is excellent not one problem...I think kenwood amps are bullsh!t now... i seriously doubt my gain was set too high when it is 1/4 of the way up on the kenwood amp...my subs are brand spanking new and i used high end home audio esoteric speaker wiring 12gauge so wiring and subs could not be the problem...my friend has the 8152d and has the same problem.

9152D is a good inexpensive solid amp. If you want better power, you need to get off your wallet and spend a tiny little bit more.... X-811D. Solid. Best bang for the buck sub amp I have seen in awhile.

buddy of mine had me hook up a 9152 and an L5 for him...and we didn't have a problem in the world...sounds like a problem with your sub...and he was sittin on a stock gm alt with your everyday...average...non-home audio esoteric speaker wiring...just the normal rockford crap ------------- 1987 Huffy...spinners...two 15's custom mounted to the back

i would take a meter and double check your wireing on your sub, make sure that it is reading 4 ohms along with the resistance of your ground, i would also take an amp meter and see how much current you've got going to your amp when it starts to clip, you might have 12-14 volts getting to your amp but if you don't have the amperage then your amp wont perform like it should either, and it's easily over looked.

both good points...but again i would concentrate more on testing the sub first since you said your friend has a 9152 and it did the same thing on his...this shows me that it is most likely not the voltage...it would be extremely odd if you both had voltage issues

I swapped amps with an INFINITY pushing 657w RMS at 2ohms and not a problem in the world and i didnt change a thing only the amp. what does that mean...it means kenwood amps are SH!T...the kenwood was pushing 550w RMS at 2 ohms...

"you might have 12-14 volts getting to your amp but if you don't have the amperage then your amp wont perform like it should either, and it's easily over looked." so if the amp clips and the amp reads 11.8v what could be the problem? ------------- Bass-oholik

This may seem a stange thing to check, but the Kenwood is a mono block and the + and - speaker outputs are not side by side, maybe you got the two + wire to speaker. We run 3 12" of the amps with no problem.

You say you get 11.8 volt at the amp. This seems low, and on a bass hit it may drop below voltage shutdown. Does the amp run hot? You say the amp is clipping, but if the amp shuts down and comes back on after a few seconds, its not clipping, but protecting itself. Check that the ground is short, and good solid contact to body/frame. Also, check the fuse, we've had more than a few (AGU) that look good, but don't pass much voltage/current. Get your voltage up over 12.5 at the amp.
