Taramps TS 400x4 400 watts RMS 4 Channels Full Range Car Audio Amplifier, 2 Bridged Channels, RCA Input Class D, Output Power, Multichannel Amplifier System, Small - TS400X4

Very happy with this amplifier for my setup. I'm using this to power two additional 4-ohm 89db speakers using low-level RCA output from my head unit. I had initially installed a Pyle amp with similar specs but the output was terrible and had to compensate with 100% gain--even then the output was low and had a noticeable hiss. Swapped for the Taramps and it was a WOLD of a difference. Set it to 25% input sensitivity (head unit puts out 2.5V) and it provides clear, powerful amplification matching the output of my head unit's speakers. Simply no comparison. *The only thing I'll mention is this unit does not have high-level inputs. They make an identical model WITH H/L for just a couple dollars more. I don't require H/L but it's something I overlooked when purchasing this unit.

Very Powerful , small and compact. easy connections no complaints. i use it to power my rear door speakers.

This little amp is exactly what 90% of people need for their door speakers and might even work for two mids and one sub if you have a two door vehicle. I ran it with two mids and one sub in my Cherokee until i had the money to buy a separate one for the sub and it held its own very well. Once I got the mono amp for my sub I dedicated this amp to my four door speakers and now my system sounds like a dream. It is loud and clear. The compact size of the amp allowed me to mount it under the passenger seat for a very clean install. I will be using taramps 400x4 for all my cars from now on. It is a superb value at under $100 in 2024.

Very good amp good power. mines was missing one terminal screw but I had extra one so it’s not big of a deal. Very good product

Two channels have static the other two are clear even if I switched the RCA‘s it’s still static on those two channels and then I hooked them up to a DSP. I hooked them up to an equalizer and nothing I do and nothing can be done about the static on those two channels different speakers different everything and those two channels have static no matter what. I don’t even use it anymore.

Good amp, packs a lot of power, very small profile. Had an issue when bridged and alternator noise, but got fixed by using an RCA splitter. Noise ground is very high. Runs cool, easy to install.

Muy buena recomendada

Wow, pretty impressive little amp.Im running 6.5" mids and 2" tweets-bridged 2 channel.Very little gain and it's loud as .... Runnings 125rms mids/tweets,no problem sound's really good for what it is.Gonna get some 6x9 for the rear if not loud enough 4 channel, I will buy another amp.I have no engine/alternator noise I have a ground filter but not needed.Im surprised my cb has terrible alternator noise thats what ground filter is for now.Im sure it could run low watt subs ok.Perfect match for my needs.My camping truck nice loud party stereo! Front speakers in boxs/tweets Velcro strips- can move around to sound better outside! Cant wait to piss off big foot lol In a few months I will leave another updated review. Update: Had to add a stinger loop filter before amp noticed altenator whine now its completely gone.Going to try more Brasil made audio in the future.

Buen producto, conecté un set de medios y dos medios ,con unas bocinas de minicomponente y jala súper.

I seen the great reviews on this amp so I just had to try it. I'm thinking to myself there's no way this is going to be a decent 4-channel amp for that price. Then when I receive the amp the thing is so tiny I almost returned it without even trying it. There's just no way in hell such a small amp could put out any kind of power unless it's full of distortion. This thing is ridiculous! It puts out such clean power with such a small size I want to buy shares in this company! I just can't believe it. It is crazy clear and crazy loud!

Es compacto, tengo conectadas dos bocinas deaf bounce de 130 rms a 4 ohms en modo bridge y con todo el volumen abajo las levanta sin exigirle al amplificador.

Great amp for the price, I've got one bridged running my front seperates and another one bridged running my rear seperates. The only complaint I have is the fixed crossover point, but I just have the crossover set to full and I use the high pass filter on my Kenwood head unit instead. But it's a great addition to your system, especially if you've only got an amp running your subs. This little amp helps boost your mids and highs so you get better clarity with your system. And the amp kit I used was the Recoil 8 gauge kit.
