HI Skimmie

Beleive it or not, you probably need a bigger amp for the levels you are trying to acheive. If you regularly crank it and the amp gets driven to clipping, the square wave produced when the amp runs out of steam will burn the voice coils in your speakers. Best solution is to be sure you are delivering CLEAN power, not distorted or overdriven. It can be a bit hard to tell at high levels. Putting an oscillascope on your speaker outputs and check for clipping at the highest level you run is a good way of checking. Then set your max levels for that so that you cannot overdrive the amp. Clean undistorted power wont burn your speakers.

If you have variable LPF or a crossover, check the frequencies you are using also., Cross them over too high, and you will cook the voice coils also

What amp would be better to use with what speakers/sub? I have a KAC-7202 kenwood 920W maximum power (150wX2 RMS, 4ohms) (230wX2 RMS 2ohms) and then the other amp I have is a Alpine MRP-M500 mono power...


I'm using that Alpine right now for 2-12" subs and I have compared it to 6 or 7 other amps this month and most were 4 channel 150Watt/Channel Bridged to 300Watts x 2 and found the Alpine to be superior in both sound quality and loudness. The Alpine has also not turned off even with full volume for hours at a time, Very solid amp I was very surprised due to it's size!

I have a 300 watt alpine 4 channel amp powering 4 x 6.5" kenwood speakers. My speakers can take up to 170 watts each. I have to turn my gain up all the way on my amp in order to get a quality bass...


Your amp is overheating as your speakers all combined are 680 watts, double your max output on your amp. Ideally you need a 1000 watt amp to do the job and for perfect sound as you should never have your amp up to max as it is more likely to blow quicker. The 2000 watt amp your are speaking of will do the job perfect, but you need to keep the gain down around 50% as you could blow your speakers. But yeah all together you are right, the 2000 watt amp will stay cool as doesnt have to work nowhere near as hard as the one you have currently.

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Time to get an old school Opti Drive. .A thumbs up would be greatly appreciated if this answer is helpful to you. lanzar-4000-watt-amplifier-hooked-up-2-shonxoarcym4awy4zl1imx4o-2-0.jpg Lanzar

Amp turns off.


your drawing/pulling too many amps. Is it a mono(one speaker), two way(two speakers/can be briged to one), or a four way(four speakers/can be brigrd to two). don't put too many speaker to that one amp if it's only a mono, or a two way.

Car Ampli Problem


forget hooking this on a subwoofer. this amp produces only 50 watts per channel at 4ohms or 70 watts per channel at 2 ohms RMS...
If you try bridging the sub, it will only give out maybe 100watts bridged.
So..... if your sub is, lets say 1000watts RMS, youre just going to bust your amplifier to smoke...
Find a more decent and powerful amp. This amp is only intended for separates and lowend subs with an RMS of 80 to 150 watts

Speaker amplifier calculation


for $85 i can sell you an Almani 900 watt 2 channel amp i would stay way away from those 3 brands they are all really poor quality and i can get you any major name brand cheaper.
I can get you a hifonics 4008 amp (800 watts peak 100 watts per channel rms) for $100 shipped with full factory warranty. you find an amp you like and i will get you a price. I am a factory wholesale distributor for most brands.

Low output from amp


From a former DJ, make sure that the speaker circuit is matching the load that is required by what ever amp that you are using. If the amp is rated at 1000watts/ channel into 8 ohm's then your equivalent speaker circuit has to match. I repeat has to match! If it does not the amp will either short out or be overloaded. If you are using all 8 ohm speakers on a amp that rate its output at 1000 watt/8ohms then you you have to match the watts and the ohms. Depending on how much power your speakers take you may have to use more than one speaker to handle the power. If you have to use more than one speaker you will have to use a series/parallel circuit to keep the ohms at 8ohm. You have to use ohms law for adding resistor in series and paralell. If more is needed please reply.

Application


I'm happy I can help a newbie. I remember when I was one and I'm happy to help you. First off, I nodiced that the fuse is only a 30 amp fuse. A quick way to see what is probably the max output of your amp is take the fuse value, in your case 30 and multiply it by the voltage you will be supplying it. Lets say you are just sitting with the car off the voltage would be 12ish volts. So your total assumed wattage is 360 watts. Which is an large amount less than the 1000watts listed. So watch out for that. Also, with subs you would want a mono-block class-d amplifier. If you need any more help at all, let me know. Good luck

High distortion


The head unit may be rated at 200 watts but it cannot produce more than ~20 watts of real power per channel. There's no way that it can drive the high end speakers to a level that will be needed to compete with the subs on a 1000 watt amplifier.
