Review: Good upgrade from factory sound - This 400w amp is a good upgrade from factory sound. However, the 1200w amp on my sub can easily overpower it with bass. Had to turn it way down. My speakers (infinity reference 5.25 in front, jbl reference 6x9 in the back) can handle more, but this works great. I have no issues with overheating over two hour drives (and it is suffocating in my glovebox...). Overall I am satisfied with the quality for the price I paid during a holiday sale. It must have been $30 or so on sale. This was my first amp installation, and I have no regrets. However my next amp will definitely be more powerful. This amp WILL distort at high volume, so adjust the gain with the dials until max volume is clear. If you want something simple that will give you better sound for a good price, buy this amp. I have no complaints about this amp for the price and power range advertised.
Review: Amplifier for the driver that's upgrading a factory stereo unit! - Perfect amplifier for me and my set-up! Has the right dynamics for a bump up to the next level of quality sound on your factory unit! It's not a blaster for competition. It provides only 50 watts at 4 ohms to four speakers (which is significant). I'm pleased with the performance and does not get hot beneath the driver's seat! If you see reviews about the unit getting hot or doesn't pump up the wattage, that's because they're not too familiar with how the system works. As long as you know the speakers wattage and max capability, any amplifier will work. Lastly, you'll know what type of speakers you'll have once you know that actual (nominal/RMS) operating wattage of the speakers. Any speaker that's significant in cost may be that it can handle a lot of wattage with a high RMS/Nominal range of 90 watts and higher. Less expensive speakers won't be used for competition sounds. So...use the right amplifier for the speakers you have or plan to get. This amplifier works perfect and serves my needs. Very happy with it and you will too!

## Questions & Answers

**Q: can u still connect this amp if u only have one set of rca in the back of head unit ?**
A: Yes you can, it only requires 1 set to operate, I don’t recommend this item though, I ended up sending mine back because it didn’t work properly

**Q: Can the 400 ev 4 channel push 4 6.5**
A: Yes

**Q: just need around 45 more watts to ONLY my highs mainly, but to Mids as well- anyone with this amp think it will do what i want???**
A: I have had this amp for 3 years now. One tripped channels 1/2 into protection mode and never came out. I got my money back and put another one in. Not a problem at all. These are great for the four 6 x 9s I run for mids & hi's. I use a ground loop suppressor though. They will wine without one. Not the best on the market, but at 40 bucks, it's tough to pass that up when the quality of sound is so awesome.

**Q: Say i wanted to hook this to four 5x7, would it sound any better than the jvc kd-s79bt radio unit i have? It's only 5 more rms per speaker**
A: I don't know about your jvc radio but I use it to push some tweeters in my 2010 Accord. Along with a box in the trunk, they add the sound I needed with the mixing of the extra bass in the trunk.The box in the trunk is on a different amp.

### ⭐ Don't buy! Died after less than a year!
*by T***Z on December 29, 2021*

Update: I purchased a Taramps 400 watt amp to replace this. I was able to remove both the noise filters so problem was definitely with the amp. Also the Taramps is much louder . This one wasn’t much better than the sound from my head but the Taramps is a big improvement. For anyone looking to replace this amp with something better I would recommend the Taramps 400 watt rms amplifier sold here on Amazon. My speakers are 50 w rms and 65 watt rms and work great with it! End update. Lost a channel in the rear speakers. Switched RCA cables and speaker wires. Still no working. Decided to use as a 2 channel amp and discovered no matter whether I used 1 and 2, or 3 and 4, there was always a channel not working. Since it wasn't the RCA cables or the speaker wiring, I decided to remove the unit and threw it away. The head unit I have supplies 22W RMS and sounds fine. This amp was way more trouble than it was worth. I will mention also that I had to use ground loop filters on both sets of RCA cables with this amp. Funny thing is I have another amp powering my sub and that one does not need the filter. I also added a 12v power filter for good measure. The sound was a whine that increased with rpms. Tried grounding the whole system same spot and still had whine so i added the filters.
