It is true but ETON amp is measured from a german magazine with an AP device and ALPINE is a serious brand and quite respected in car audio.They can print anything they want for specs. The real proof is in the testing here!
I provided Canada warranty service and mass modifications for Alpine of Canada for years. It was like the lonely Maytag repairman because the product was so solid. The stuff was built very well. The warranty service rate at the time was something like 0.5% and most of what I saw for warranty service was due to being run long and hard or simply being damaged by abuse and not because of poor manufacturing defects.It is true but ETON amp is measured from a german magazine with an AP device and ALPINE is a serious brand and quite respected in car audio.
If you go to that site there are tests of many amps but in general JL AUDIO has more powerful amps with a bit higher distortionJL Audio has been doing Class D for several years. They must be pretty good by now.
Is that still the case with them? I saw some tests of KENWOOD EXCELON amps i found them well built how do you find these?I provided Canada warranty service and mass modifications for Alpine of Canada for years.

I don't know. I've been out of consumer electronics for some years now.Is that still the case with them? I saw some tests of KENWOOD EXCELON amps i found them well built how do you find these?
I'm using this Pioneer amp in my RV, and when playing music fairly loud for a while, the amp became noticeably warm, even hot, to the touch. I was playing music into Dahlquist ALS-3 speakers (4 ohms nominal, but I've never seen them tested). The amp was bridged, so driving four-ohm speakers will mean it is current-limited. The amp is fuse protected, but in my case my testing blew a fuse in the speaker before the amp ran out of steam. Sound is quite good considering the acoustical nightmare that is my 50-year-old GMC motorhome.
I mounted the amp on the inside of a fold-up panel that covers the fuse block for the chassis 12-volt systems. The power for the amp and the head unit comes from the house 12-volt system, and the main power feeding the amp comes from a fuse-protected circuit straight from the main power take-off terminal that the chassis battery is connected to. I'm using the amp-control signal line output from the head unit, which is a Kenwood in-dash car stereo from about 15-20 years ago. That works well--when the Kenwood unit is in "Standby", the amp turns off. Inputs are from the line-level outputs of the Kenwood unit.
Note that I did not shorten the wiring harnesses. The proprietary harnesses might be difficult to source in the future and there's always a chance with my stuff that I'll move it around to other applications.
Amir mentioned that the amp only became warm. I think mine was more like "hot".
I'm using the head unit to drive the front speakers, which are in the ceiling adjacent to the cockpit seats. The Kenwood head unit is rated at 50 wpc, whatever that means. Those speakers are 3" full-range 4-ohm car speakers, and the Dahlquists are like subwoofers in comparison.

Car amps get hot. I mean oil burning, steam inducing, finger hurting heat. What impedance/speakers are you running off the amp?I have this amp that I just installed in a camper an it gets really hot. I used it before in a truck before and did not noticed the amp got this hot. Did you change or do something to keep the amp from getting really hot?
4 ohm..Car amps get hot. I mean oil burning, steam inducing, finger hurting heat. What impedance/speakers are you running off the amp?
Hmmz... 4 Ohms should be a good load for that amp. It does draw 15 Amps according to the fuse and so I would expect some power inefficiencies that create heat. The thermal cutoff is probably 85C. At 85C it will be very hot and cause pain within moments of touching it.4 ohm..
I will redo the power and ground connections this evening and hopefully that will help. I was told that campers sometimes have weak power systems.Hmmz... 4 Ohms should be a good load for that amp.
