I purchased a kenwood 1200w sub and a kenwood 1000w amp..is that too big of an amp for that sub?? and after around 15 or 20 min. the sub will play some bass notes and cut off and on play notes and skip some..is the problem amp overheation? how can i fix this?? thanks
By chance is the sub a dual voice coil sub if so you can change the inpedance going to the amp.also if you don't have at lest 4gauge wire for power+ground you ground wire is as important or more than your power wire it is a somtimes a common over sight make sure the ground is as short as possible and in good contact with the vehicle frame

Re: Car Audio (amp over heating)
The problem would be if you had it switched around. The 1200W subwoofer only means that it can handle 1200w of power the 1000w amp means that it can deliver 1000w of power. What you may have is an impedance mismatch. My question is what is the resistance rating on the sub woofer and what is the minimum resistance rating of the amplifier. These are actully the important issues at hand.
the rating of the subwoofer resistance in Ohms should never be lower then the minimum resistance rating on the amplifier. in fact the resistance rating on the amp should match the resistance rating on the subwoofer.

well for 1 , musicc is goin in an out that means ur grounds not big enuff or its not getting good ground thats why ur amp is getting hott to becuase u got all that power but no ware for it to go so check the ground for me an if ur music is still doin that then try ur acr wire unplug one of them when musice is low an plug it back in an unplug the other so on , i would love to know if this help an please vote
Sony is not a bad brand if you use it correctly... This is what is happening my friend. You are what is called "clipping" your amplifier. What you need to do is make sure you are running your subs at the correct impedance or also known as resistance. Then make sure you are running them at the correct frequency, there is a turn tab on the amp to match the sub to the amp. Then never never turn the gain all the way up. This over works the amp and will wear it out much faster. This also does not actually give more power to the subs it just gains the power sooner then later. Never turn the gain more then half way up.. Hope this can step you in the correct direction my friend.
1 OHM...ONE... sheesh now thats a low resistance for anything... If they are only 500 watts and they are in parallel, series well NO.. your amp puts out wayyyy too much for those speakers.. 1200w versus 500 watts by 2... srill NOT enough "Head room" for it to be safe... about half is all you could expect before Pop.. sound is heard.
unless you are a technician do not mess with the amplifier.
it takes years of school to learn electronics. unless it is a blown fuse or something simple,you will never fix it.
i did kenwood warranty for 8 years and the amplifiers are difficult to repair.
bigger the better my friend. Look at your Peak RMS output, and how long of wire you need. Then you could make the judgment call on how thick or what gauge you need. (2 involved factors power + distance). id say 10 gauge and you would be fine.
comp VR 15s are rated @ 500W RMS 1000Peak.
The lanzar vibe amplifier is 2 x 600W RMS at 4 OHMS 2 x 1200W MAX at 4 OHMS 1 x 2400W MAX at 4 OHMS Bridged 2 x 1000W at 2 OHMS RMS.
Your subs are single 4 ohm subs.
If your subs are wired stereo, they both are seeing 600W. (more than the rated RMS)
Chances are, you have them wired parallel to a 2 ohm mono load - of which that amplifier is not rated. In theory, it will produce about 2000W @ 2 ohm mono for a short period of time.
Your amplifier is too powerful for your subs. Turn down the gain setting to 3/4 or purchase better subs. Also be sur the subs are inthe proper enclosure. It sounds as if they are excurting past their linear x-max and colliding with the rear bump plate. This will cause damage down the road if left as is.
Maybe, but my question would be will the truck alternator carry the
load without frying. Also you will need one hell-a-chous size of
battery and ground leads in order to feed that much power from the
front of the truck to the amps in the trailer in back. I would
think that some really big boost capacitors placed at the amps would be
in order too. Also, you didn't mention how many amps you were
using and what amperage they would draw. That is criticial
information before you can figure out every thing else. Good luck.
