Review: Amazing Amps for the price - Insanely good little mini amps, Very clean sounding - some speakers may have audible hiss if gain is up too high if they are very sensitive but if you are feeding strong voltage over RCAs turning gain down easily tames it. These can get a bit warm if you push them too hard but testing at high volumes for hours on my setup only left them slightly warm to the touch so I don't think they are as bad as other mini Class D amps and if you have heat issues you are probably doing something wrong.
Review: Buy it you will not regret it it’s amazing - Came in quick really good build quality the top is a metal cover or cast type but still very nice got some weight to it super compact like 4x3 inches can’t wait to install behind the dash Finally installed it and I’m at a loss for words this amp is amazing sounds so good packs a punch I will now on always install amps to my door speakers specially this one and I’ve never been a door speaker amp guy but this amp changed that

### ⭐⭐⭐⭐⭐ Big performance small package
*by T***E on August 21, 2024*

It's small. I can't begin to express that. It's the whole reason I bought it. I needed a small amp for my old CJ 7 Jeep. At the price point I was very skeptical but not being made in China was a good thing. Install was straight forward max wire size is 10awg for anyone looking to purchase a wiring kit at the same time. I installed mine on the plastic air box under the dash (only available spot out of the weather). Performance is above expectations even more so considering the size and power rating on this unit. I'm not running a subwoofer only 2 6x9" speakers in the rear and 4 6-1/4" speakers in the front. If I was going to have a sub I would recommend stepping up to the 1000 watt unit (only slightly bigger based on dimensions given) I will update this after several weeks worth of driving. I'm getting ready for a road trip to the beach so it will be a great test of highway noise vs sound system. Update as of 9-15-24 This thing is amazing. Wonderful sound quality and even with off road tires and no top or doors I can clearly hear my music blasting out of my speakers. My 4+ hour trip was fantastic with the sounds blasting from my speakers. Previously I would have the volume maxed out and still barely hear the music over the wind and tire noise. Not anymore now with this little unit I don't even hit 50% volume on the quietest of songs and typically only have it at 20-25% with most. I highly recommend this for anyone looking for a compact amp that will greatly increase the quality of their sound system.
