i have a kicker kx800.2 i think it is and it keeps cutting out. it will hit for a lil bit but as soon as i turn it up it cuts out. the amp is getting power so i dont know wat the **** it is
I looked it up, it is only a 2 ohm stable amp. Describe the subs/speakers and how they are wired to the amp... Also, how did your buddy ground the amp, in detail?
Um...how is the gain set??? Voltage dropping so low that the amp goes into protect?? How come most problems come up when "a buddy of mine installed it"
its a directed audio sub its grounded the the floorpan and i've checked that the gain is set pretty low i couldnt tell u how low the sub is bridged from the amp and yea it allways is that buddy of urs that messes it up
Buy or borrow a volt meter (handheld) make sure it is in the DC volt mode and <20volt range..Put the black ground lead on the battery negative and red lead on battery positive...With car running, what does it read? (should be 13.6 or higher).....leave black lead on bat. negative and put the red lead on pos. connection on amp...What does it read? it should be the same as what you got at the battery, if not, you got a bad power cable or connection....if the same...check the ground......Leave the black lead on the bat. negative and put the red lead on the amp ground terminal....What does it read? it should read zero....if not check the point where that cable is connected to the car...what does that read? Should be zero...if you have any voltage reading on the ground side, you have a bad ground....If you have the black lead on bat. negative and the point where you are thinking is a good ground, you connect the red lead and get a voltage reading, you have a bad battery to chassis ground...Run a new one or clean the old one, or replace the cable.. If all of this checks out, make sure to check the remote turn on wire. if the amp cuts out, does the voltage drop there?....If all of this is good, then you know your map is getting good power and is properly grounded....if you are running an impedence load lower than the rated, you could very well be shutting the amp down cause of excessive heat...in this case you need to make sure of the impedence of the sub and that it is correct for the amp... Without really knowing these things, all we have is educated guesses without knowing what is properly connected or configured....Your local Autozne could sell you a volt meter fairly cheap or rent you one....if you are not sure how to set it...ask them...Tell them what you are checking with it....I would encourage anyone who did not own a meter, to buy one.....This takes the guess work out of knowing if you have adequate power and grounds...Voltage drops and if you buy a nice one with an iductive amp lead, you can even check current draw very easily Willy
just want to make sure that the amp is grounded to the floorpan, right? - not the subwoofer.. right? like rodney said.. if that amp is rated at 4ohm stable under a bridged load, and you have a 2ohm load on it, you will definitely be cutting out at higher volumes.. plus it's not good for your equipment. does it play fine at low volumes? - yes you get "more power" running at 2 ohms, but at what expense?
