i have a kenwood head unit, kenwood 350w amp and 2 12 inch mtx subs. but if i get above volume of 25ot of 39. my subs like to cut out on bassy songs. does anyone know why this would happen. i am thinkin it my be my amp, is to small to power my subs. also not sure wut my subs wyttage or amps it has, idk much about my system havent had time to do so. heres a photo of them. please them know cuz i hate when they cut out. it makes my system sound dumb and embarrasing dont wrry im gettign a box made for them, there not actually goign to stay like that.

thank you

 

400 was barely enough for my 10's lol

 

so i should go get like a 850w amp or so.

 

Those subs cant handle the wattage get some alpine type r!

 

I would say you are overloading your amp. Please provide the model number of the subs and amp. Also do you have the subs wired in parallel or series?

I would bet you have the subs wired for less ohms than the amp is stable at. So when you try to crank it up, the amp shuts itself down.

 

i think im just going to get better subs and an amp.

 

That may or may not fix the problem. I'd look into it more before you dump a bunch more money. It would also help so you don't run into the same problem with your new stuff.

 

their is a few things i would check for this problem\

First off ? do the subs just not play as loud when turned up or do they totaly quit playing?

if they totaly quit playing i would check how hot your amp is when they cut out (if the amp is to hot to touch) = BAD if warm and you can keep your hand on it thats a better sing

it could be ur cd player clipping as well so dont be 100% sure its the amp yet...

do u understand series vs parell? if so check out how the subs are wired in and look at the bottom of the amp it should say how low of Ohms the amp is stable to

if your ohms are to low for the amp it could be going into safty mode which would be your subs not playing at all untill the volume has gone down enough to be safely played again


To small of amp isnt a bad thing by any means unless your driving the amp into clipping. Basicly instead of a nice smothe in and out the sub makes a cliped signal (square shaped signal) this to the sub is like hitting a wall!

 

ok cool. thanks for the info, when i get some time over the nice weekend i can check it out. the thing is, when they were in my freidns lumina he said they worked fine.

 

My Firebird had this problem the amp was not powerful enough for my 12's So bought me a 1000watt and gave my wife the 500w and now it does this in her car pushing her 450w 12. Hers cuts out at about 25/32. More powerful amp should work have any friends with stronger amps?

yeah i got my friends 600w mtx audio road thunder RTP251D amplifier. solved the problem of it cutting out. now it can go above 30 with out it doing so. also it doesnt sound to good after 27 or so.

 

You might want to mess with the headunit equalizer and turn the lows down My system has them low so I can turn my radio up with out the speakers getting distorted or just get better speakers.

i got a kenwood head unit, dont know wut kind though. also i have pioneers in the sail panels, and stock in the dash. when i get a new dash pad, i am going to replace them as well.
