Review: Car Option - Car Option! I was looking for a replace amp for my Truck for stero speakers. Took a chance on this and it works perfectly for my 10s. Easy to install and works. Good investment.
Review: Good Amplifier - I never planned on using this amplifier for marine use, for the price, and being 4-channel, I wanted to use to power my car's main speakers. For this use, it's awesome, I can get my speakers beyond the stereo head unit's RPM rating of 35watt per speaker, close to the speaker's RMS rating of 50watt. This in turn makes it so I don't have to buy a newer stereo head unit to get better or louder sound. This will also make the bass come out better. The only complicated part is you have to have your stereo unit go to this amplifier's input, and then the outputs going to your speakers. I used quick disconnects for this purpose so if I needed to take out the amplifier I could still get my radio hooked up quickly. This all is time consuming, so expect this not to be a plug and play experience for the average person. Concerning the waterproof part, for my purpose this part doesn't affect me, but the product's description says "waterproof" because of it's marine usage. I want to take note about what the instruction manual says about this; it mentions if the unit gets wet or damp, to IMMEDIATELY wipe and dry it off... that doesn't sound waterproof to me, more so, the speaker connectors are like any other speaker connections where you screw on the wire, and are exposed to any weather conditions if the unit is not properly mounted in a waterproof location, if somehow you could a decent amount of water spilled on this area, it will most likely bridge and short out, but that's just my 2 cents.

### ⭐⭐⭐⭐ Greatsound and INEXPENSIVE
*by R***R on September 29, 2014*

Pretty impressed with this inexpensive little amp. I AM a bit of an audiophile, I like CLEAN music and sometimes like it LOUD without distortion. I have a competition quality $4000 stereo consisting of all Phoenix Gold amps three in fact, two Kicker Solobaric 12's, Kicker surround speakers for the rest of my system and it all puts together a CLEAN very LOUD awesome stereo that sets off car alarms and can be heard for blocks and blocks if I want it to be, but unfortunately none of that is waterproof for my Jeep. I figured I'd give this little guy a try, it is running two 6.5 Sony marine speakers in the doors and the Infinity Reference 6912m 6 x 9-Inch 300-Watt High-Performance 2-Way Marine Loudspeaker (Pair) in the back ( purchased here on Amazon as well ) and sounds pretty darn good, To tell you the truth for less than a Grant, this IS a really impressive little amplifier. I'm going to get the two channel amp as well and a couple of inexpensive Pyle 10's to add some MORE bass to the Jeep ( really can't believe how cheap this stuff is, I always considered pyle as just that a PILE of China *%*#& but I admit I was wrong,I have had nothing but GOOD experiences with this low cost audio ). It is great to have a good sounding stereo in my Jeep, that I don't really have to worry about it getting wet or worrying to much about being a target for thieves, most folks consider Pyle products the way I USED to. PLUS, MY ENTIRE SYSTEM COST LEES THAN ONE SPEAKER IN MY PREVIOUS SETUP - THAT ALONE IS AWESOME
