Timpano 4 Channel Amplifier Car Audio 4 x 125 Watts 2 Ohm, TPT-500.4 Small 4 Channel Amp12 Volts Full Range Class D Mini Bridgeable Car 4 Channel

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.

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.

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.

Very compact and easy tk place somewhere if you have a small car (01 mazda miata), helped power my 4 jbl speakers (two 6x8s and two 6.5s), only thing someone might have issue with is how to set up the speaker wire due to only being three holes for each side

Sound super loud!! Let see how long they last!!

Bought a custom speaker set up with this app installed for my Harley softail. Within a few days, one of the channels started to distort big time. I’m not a tech person, but it sounded like there was a seriously loose connection on one speaker while the other speaker worked fine. I thought it was speaker so I bought new speakers and tried to replace it, but it did the same thing. Reason being is because the speakers are easier to change in the amp due to the location of the set up on the bike. Once I realized it was the amp I bought another amp same model and swapped it out. I thought maybe I got a bad one. After about a week of using it, the same thing happened to one of the channels. And then on the ride home, the other channel also went. Learn my lesson. I don’t think these are rated for vibration resistance on a Harley..

Exelente

Loved this amp man was it powerful but it only lasted till the end of July heard this noise and no sound wanted to get it fixed but it was beyond repair
