Pyle PLMRA400 Marine Waterproof 4-Channel Amplifier
Pyle PLMRA400 Marine Waterproof 4-Channel Amplifier is rated 3.5 out of 5 by 4.
Rated 4 out of 5 by from Good straight forward low cost Marine AmpI have installed several of these amps in my personal applications as well as applications for customers. They have done the job. To get the best out of this amp I will offer a few tips:As noted, use full range speakers with this ampAs with any amp, Install with a heavy gauge, wire recommended for your max current draw and fuse all marine applications at both ends.Solder and liquid tape seal all connectionsEven though these amps are noted to be waterproof, mount them in a dry locationUse a high quality noise suppression device to avoid problemsEnjoy!

Rated 3 out of 5 by from Good deal for the MoneyGood price, easy to hook up, waterproof, but 400 watts, not with a current draw of 120 watts ...duh do the math. Yrs ago I had a 25 watt x 4 ch and it was identical in all ways made by R.S. With an 8" sub it works nicely (2 600 watt pioneer 6x9s and 2 6.5" JVC 200 watt powered by amp , 4 ohms is best) it has a great responce , but dont expect 400 watt , physics wont allow that. But for $60.00, postage and all, its a good buy as usual with Parts Express!

Rated 4 out of 5 by from A good deal for full-range speakers.No built-in crossover, so make sure the speakers you are running off of this amp can reproduce as much of the Hz range as possible.Just a basic no-frills amp for not a whole lot of money, overall a pretty good deal when you factor in that it's water resistant.

Rated 3 out of 5 by from OK for the money.The amplifier produces good sound with a nice freq. response. It's just a "basic" 4-channel amplifier. It does'nt have any special features, and it is not "bridgable". Will ROCK a set of full range speakers!

I would like to run three of these off of one power supply.  will this power supply work for this purpose?

Asked by: zz11
Yes that power supply will work fine with two of those amplifiers.

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>

Asked by: Rich from Adrian
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?

Asked by: Stevedrivr
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.
