Title: Awesome amp
Review: I installed two under seat subs and eight and a 10 in the driver and passenger side and later over 120 ft of wire in my car with this amp connected to the front two and rear two speakers.I want to say it's like day and night with this amp for the way the speaker sound, they sounded okay but now they sound great and with the addition of the subs I haven't had a car that had such full range and clarity before great product a lot of work very affordable.

Title: IT’S NOT THE AMP’S FAULT!
Review: ***UPDATE 8/4/18***I went mudding a week ago and accidentally sank my jeep in a pond 🙃 Completely flooded the floor of my interior and soaked the amp, luckily it was off. A couple days later I ripped the entire interior out and washed it out really good, like literally washed the inside of my jeep with a hose. I figured the amp had already been soaked what more harm could I do. Got everything back together after drying out, fired up the jeep, turned the stereo on and BAM! Perfect sound quality. If it can get soaked twice and still work I think that says something.*end of update*Did you know, that running your power lead in close proximity to your audio cables can cause loss of sound clarity, distortion, and you guessed it, alternator whine?! I’ve had to fix plenty of botched installs due to this. I did a little test and ran my audio cables directly next to my 4g power lead going to both my amps. Heavy whine and almost no signal clarity. Re routed my cables to run on the opposite side of my power lead and wow! Signal was clear, bassy, and no alternator whine.This amp is phenomenal and woke up the old Bose speakers I pulled out of a 2001 Pontiac GTP (2ohms at 50 watts RMS, give or take). I drive a Jeep Wrangler TJ and space is precious, so I can’t have big amps and fancy subs. This fit under my driver seat perfectly and cranks some serious audio to my speakers, even with the top down. Great price for a quality low budget system and I get lots of compliments from friends. GREAT AMP!!!

Title: Junk
Review: Piece of junk. Dont believe me then go ahead and get it. Waste your money. Amazon should not be affiliated with this junk. Edit: So if anyone comes accross this and wonders, then I'll go more into detail about why it is junk. 1. The amp amplifies any electrical noise inside your vehicle on top of the never ending beeping sound it already makes. (Read the other reviews about this. It's way too common to ignore.) 2. The amp does not put out clean sound at all. (I used this for my door speakers.) I know this is not clean sound even when comparing this amp my also budget 2 channel "Do" amp it sucks. It can make your speakers sound blown. The amp throws random frequencies to your speakers whenever it wants because it has a built in non-adjustable crossover. It's not always giving you example: 10hz-20khz the full time if you want it..Based off what I know. If the amp you are wanting to get has an adjustable hpf and lpf then it will most likely give you the sound you need. Make sure to read reviews to see if people are having grounding issues with the amplifier causing it to make harsh noises. Still on the budget side of things you get what you pay for. Just don't agree with boss ripping people off with this amplifier.Do your research. I hope this review helped you learn from my own mistake. FACE PALM.

Title: Good 4 channel amp for factory speakers.
Review: While the amplifier claims to deliver 4x50 watts, in my testing, I found it pushed around 41 watts per channel at 14.8 volts. It’s effective for factory setups, providing clear and punchy sound that makes your music more enjoyable. However, it struggles with non-factory speakers, which limits its versatility.

Title: This amp is kinda okay
Review: The first one I received I didn’t even hook up, when an opened the box the amp smelled like it had already been burnt up. Sent it back got another, this one works but has the most annoying buzz very loud. I got this amp because it’s small and fits inside a box I’m making. Will replace this one when I find another small amp.UPDATE: bought a good ground loop idolater and it solved the buzz issue.

Title: I set the gain and can’t complain
Review: I added this amp 400 watt 4 channel to my harmony audio door speakers 300w peak 100 rms. I went from my output of my existing subwoofer amp to one channel and the other channel came from the head unit. I have a ground loop isolator installed on the subwoofer. I never had noise or problems from the boss audio amp. Set the gain and can’t complain
