I needed an amp for my jeep wrangler. I wasn't gonna spend a lot due to weather and possible theft. This little amp was perfect. I have it running 2 sets of 5.25's and they sound great.

### ⭐⭐⭐⭐ 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
