Pyle PLMRA400 Marine Waterproof 4-Channel Amplifier
Pyle Amp connected to front and rear speakers. The rear sound great but the front cut out after about ten minutes. When the volume if turned up the front the sound goes out. If I turn down the volume it comes back

I'm wondering if this amp will sound any better than the stock 20 watt amp on my 86 Kawasaki Voyager. Also, will heat build up if mounted in a saddle bag>
Unfortunately we cannot say whether it will sound better than the original amplifier or not. Amplifiers like this require some ventilation but they usually do not get hot to the touch. This is something you will have to test.

What is the true RMS rating @ 4ohms and at what % THM?
The specifications aren't all that clear about RMS wattage or THD, however, they are clear about a couple of other things...The supply voltage should be between 10 and 16 volts, the amperage the unit draws does not exceed 10 amps. 10 amps times 16 volts is 160 watts. The maximum power this amplifier could actually do is 40 watts per channel.If they specified that at 8Ohms, then a 4Ohms speaker will allow the amplifier to run at 80 watts per channel.THD% usually increases with load on the amplifier, so a 4Ohm speaker will run this amp with twice as much THD as an 8Ohm when the same level of gain is applied.RMS means Root Mean Square and its a statistical calculation applied to the raw output of an amplifier to try and ascertain a power output level that reflects the true strength of an amp, without published numbers the best we can do is a guess, without knowing how they came to their MAX wattage numbers that guess becomes even more hazy.Unless your speakers are rated at less than 20 watts each, this amp should drive them without killing them.If your speakers can handle more than 100W then the limit will be the noise (THD%), turn it up, (the small gain knob on the amplifier,) until its too hard to listen to, that's all.
