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.

so this amp is the size of my palm and i have small girl like mechanic hands. looks very compact but feels so light and cheap quality but i bet you inside must be robust because this little amp powers up my TW67 pyramid on 4 channel bridged making my tweeter scream in my truck. i would recommend this amplifier if you need to power up door speakers, tweeters. i’m very pleased will buy other taramps amps.

Too powerful for a small amp. Simple and high quality

I don't normally leave reviews on products I purchase, but this little thing deserves one. For the price point, I am floored. I bought it to power the door speakers in my car because the head unit was underwhelming on its own. I didn't have super high expectations because it is just an affordable amp from Amazon. But I was very wrong. My stereo is incredible now and the sound quality is fantastic. Highly recommend.

This small amp is a beast. Very powerful and it does the job right. With power and clarity. No clipping.

Received amp very quickly. Cudos to delivery driver. Connected amp up in house first. Kinda makeshift lab of sorts. 12V 30a regulated supply. Connecting power and remote easy peasy. Same with speakers. Although Taramps has unique methodology. 4 speakers, 2 of which are wired in series (new one on me?). Clearly amp isn’t happy with low impedance. With RCA cables connected, but no incoming signal. Slowly increased gain. The amp power supply was connected to voltmeter/ammeter. Before any gain adjustment, 12.2 volts and 0 amp(s). Increasing gain acted like an output stage bias adjustment. No signal, but current draw increasing substantially. Included a video. The RCA cables were disconnected and gain set approximately 20-25%. Starts at 0 amps, and all by itself increases to nearly 4 amps, then back down to 0 (protection circuit?). In the space of maybe 30ish seconds heat sink went from 73F to 103F. All speaker cables properly connected. No dead or partial shorts. Sending back to Amazon for refund. To test my lab rig connected ~15 year old 100wpc class AB plate amp. Worked great; no power, noise, or over current issues.

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.

Used this in my step sons 2002 mustang when his mach system died. Bought 4 new jbl 5x7s. I have always set amp gains to 50% and go from there. DO NOT DO THAT!!!. AT 50% Gain soon as my bluetooth connected I got about 1 second of audio then pop. Blew the tweeters right out of the door and it shut down. Turned car off and back on. Amp came back on but tweeters were trashed. I set gain to 0. All the way down. These knobs are almost impossible to turn and very sensitive to react. So before you mount anything or put anything back together. Set it all to minimum with low source volume and gradually raise .... carefully

5 star only because I couldn't give it a 10. Installed on a harley davidson with some 5.25 ds-18 speakers and its insane. I was cruising around with volume at 20 and now I run volume at 8 and its almost 2 loud. Its tiny and fits in anywhere you'd like. Would 100% recommend this amp. Small but mighty.

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!

Llegó bien, suena fuerte

I'm not sure how they do, but for an amp to be 4" X 5" that you could just about put in your pocket ! This amp packs a serious punch. Running it as a two channel bridged configuration and it drives JBL 5 1/4" speakers with ease. Seriously loud. Very impressive little amp, I wouldn't highly suggest you try one. Oh and something not made in China ! Built in Brazil.
