    • Tiny cool lil hog THE FIRST TIME
I really like how small it its. Crossover options are very limited, but for the size its nice that there is a LPF and HPF on all channels, even if they are both fixed at 90hz. Powers my Rockford Fosgate 6.5" component set, and both of my Earthquake SWS 6.5 woofs in the doors. Clear, minimal distortion. The best part is the size though, it's smaller then a thick sandwich on wonder bread. 3"W x 5"L x 2"H. I'll be buying another one to replace a larger, less powerful amp very soon. EDIT: Bought another amp 4/1/24. I decided to run each of my 100w subs on each channel of this new amp, bridged for absolute minimal distortion and obviously maximum output. And....rear channel is dead. No working. Ok, so checked all my connections, swapped the wire, not a peep. I went to maybe switch them around again and I noticed that when you hold the RCAs against the amp it would complete the connection and sound would cut in. Let go, cuts out. Its like when you had a bad headphone jack and had to hold it into the plug. Well I cant do that, when the amps under the backseat in my truck. Returning, hopefully the next one that comes is perfect like the first. Now I gotta dig up the box and packaging, at least the recycling didnt come this week. I had mega faith that the second amp would be fine but no dice. Fingers crossed. Will update. UPDATE #2: Replacement amp works well, all channels. Just like the first. Had to have it because the size is just perfect to fit in the space off the back wall under the back seat in my extended cab 2500. Both amps, equalizer, and all wiring fits nicely. Would buy again. Test as soon as you receive it. ... show more

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. ... show more

    • Great foot print, even better door mat. Trash
I just purchased this same amp (500.4) for the second time. The first one stopped working after a year and the second (new) one lasted a little over a month. Just past the manufacturer warranty. You guessed it? They won’t refund me my money nor will they send me a replacement. Short story long… don’t waste your money. The seller didn’t even try to accommodate me, he just pushed me off the manufacturer who hasn’t even tried to reach out to me. Awesome… not! ... show more

    • Good budget option
This thing has power, it drives a 10" sub no problem, the build quality seems solid and the size is shockingly small! I would say this is a fantastic budget option at less than 1/3 of brand name units. the distortion isn't too noticeable at low volume but when cranked it becomes mor apparent, its plenty good for most people though, i have it mounted in my glovebox with room to spare! ... show more

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. ... show more
