Review: EASIEST AMP INSTALL. SOUNDS GREAT. LOOKS SLEEK. ON THE FENCE? JUST BUY IT, ITS WORTH IT. - this thing bangs, and I can't believe I got it for the price I did. My sub amp slaps too, but it's fromba competition (coughBOSScough) and I thought it was pretty decent, considering im not trying to win competitions or anything, but I think this amp processes the sound wayyyyy better. it's just rad, and it was super easy to setup. literally it's 4 screws, 2 connectors that you wire to +/- for each channel, a remote terminal, and power. that's it. you can't f this up, as long as you can read and have the wire gauge minimums covered. I'm very happy, would definitely recommend. Don't have any pictures of the finished product yet, but here's what's in the box. super simple and super clean.
Review: good cheap fun - Put this in my 2003 jeep TJ. I have a cheap media reciever installed running this with 4 rca inputs. It is powering 4, 5.25inch pioneer speakers. I can really crank this up. It will not win any awards but it is loud enough. I cranked my stereo all the way up and adjusted the gain almost completely to max with no distortion. My biggest issue was getting a good enough ground to eliminate the alternator whine.Bare metal is the key to that. So for $100 I have a pretty kick as stereo in my jeep TJ. Speakers $40. Head unit $20. This amp $37. I already had 2 sets of RCA cables and the speaker wire. I did spend $3 on a 30 amp water proof fuse holder that I ran to the battery for this amp. I am adding a subwoofer as we speak just because I got the bug. Looking to spend under $40 total on that as well.

### ⭐⭐⭐⭐ 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
