This is definitely one nice four channel class D car audio amplifier at this price point! It was simple for me to connect since I have installed many other similar products in the past. The unit functioned well right away with no issues at all and was simple and intuitive to adjust. The power output and sound quality are both excellent, and the size of the amp is pretty compact overall. Only time will tell how long it will last, but for now it looks great and sounds great with plenty of power for my needs, so it receives the top ranking and recommendation from me!

4 channel amp (100.4.D) [see 1000.D next/below] Nice little unit. However, the first one was a dud. Exchanged it for another one and it worked with no problems. I don't have a dyno to test true output... but I believe their numbers are actually correct. The total fuse rating indicates that as well as volume in my system per my ear. My speakers can't actually handle what this thing will put out and distorts pretty badly at high volume when the gain is all the way up. This is the speakers though and not the amplifier. Comes with nice screw terminals and all the options you expect out of an amp (other than specific frequency boost). I call this a win, but couldn't give it a 5 star due to the first one being a dud. Leaves a bad taste in my mouth with their manufacturing consistency. 1 channel / monoblock 1000D: Great little amp! Very small foot print! Works like a charm and is true to its output specs. Awesome little bass knob with clipp and protect lights. Has all the standard adjustments that you should expect on an amp. Great little amp for the price tag! Highly recommend! Made a video review for this item - took a long time making it and Amazon forced me to review both amps on one review and only allows one video per review ... hmmmph.

Not powerful

This amplifier worked great when I installed it but didn't last long. I purchased it right before Christmas and it just quit working this week. I checked the fuses which are on the inside of the amplifier and both were okay. The power light was working and the clipping light was out like it is supposed to be but no amplification to the speakers. I took it off line and put another amplifier I had back in its place and everything works again so that tells me that the signal and power wire and remote wire are working and all voltages are correct. So just because I had this same exact amplifier in my truck I decided to swap it out with the one that quit working and got the same results, didn't work in my truck either. I went back and checked this amplifier on Amazon where I purchased it and it is showing currently unavailable. I just hope I can contact plinius and see if they will honor the one year warranty but who knows. I guess that's what I get for being cheap. The one in my f150 still works great though so far.

This amp is well constructed, delivers plenty of power to your speakers. The smaller size of this amp is beneficial when mounting the amp in an inconspicuous location.
