Great Product. Easy to install. Works Great.
I have an aftermarket, Android radio that did not provide enough power for my speakers. It has right and left low level outputs that I could have used for an external amplifier, however, I would not be able to adjust the speaker output for front to back in the Jeep which I need. I needed just a little more amplification, so this worked well for my application. It plugged directly between my Android radio and the connector, so no real wiring needed. It has low level outputs, but I did not need those (my radio has these). The low-level output seems to have a gain adjustment which is nice. I used a different brand before this one and had issues, so I spent a little more on this one and it works. I also have a subwoofer with amplifier in the Jeep which I needed to turn up the gain on to compensate for the added boost from this (not surprising). Right now, I have a little too much overall boost from this (and my subwoofer) and I wish that this amp had a way to turn down the gain. Otherwise, I am very happy with it. Also, I expected some level of noise on the system (boosting an amplified signal usually results in audio artifacts) however, it's really not noticeable (it's a Jeep and pretty noisy anyway). If you are an audiophile, you probably would want to go a different way.. but then again, if you are an audiophile, you would not have an Android radio in your vehicle.

Ok mini amp
It's actually holding up more than a year later. Pumps my Jbl door speakers great. 1 minor problem is it gets hot pretty quick due to size.
F**S
GREAT equality
AMAIZING sound quality in a teeny tiny package
J**R
decent sound for small footprint
NOT TOO BAD, tiny but decent sound, would recomend

Died after about 1 minute while setting gains!
The one I received died as soon as I started to adjust the gains. Sent it back.
I**O
I like
Running my 2 skar audio 6.5 and 2 3 way 6x9 for 3 months now, love it. good audio quality. Honestly when I first got it I didn’t notice the little things to adjust the audio so it used to cut out when I turned it up too much but it’s too much for my speakers I have it like half way up and it’s loud would recommend

Decent for the Price and Size
TL;DR: The internals are limiting the capability of this amp from becoming a 5/5 product.Pros: Affordable, Small Build, Simple Set-up, Good Power, Good looks.Can't find a cheaper amp than this one that is also in this small of a package. Drives my 6x9 pair and 6.5 components really well. Can't say the same for tweeters.Cons: Hiss on Tweeters (or any high sensitivity drivers), A shared "ground" between two channels.I was so impressed by them driving those woofers that I bought 3 more before I tested this on my tweeters and midrange coaxials. Thank the heavens for cancellations because I dreaded to hear that hissing sound coming from my tweeters.I have a DSP that can output more than the 4v output my Head Unit delivers on the RCAs so it's not a noise floor issue. I unplugged the RCAs and the hiss was still present. From what I have learned, this amp does not have a good filter to come along with it meaning it will produce high frequency noise regardless of how much voltage you pump through your RCA.Granted, the noise was low enough that you could probably drown it out if you haven't done any acoustic treatment to your vehicle and are always traveling through highways. If you are younger than me (31), it would probably be more apparent to you but for me, the noise is evident enough for me skip this amp and give it a 3/5. If you are older, you probably wouldn't even notice the noise and if that is the case, enjoy this powerhouse!
