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.

This little amp was a major upgrade for my interior door speakers. Sounds great

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.

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.

Super easy install and very small and compact but packs a big punch super loud I absolutely love it. Highly recommend for mid/high speakers

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.

Too powerful for a small amp. Simple and high quality

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.

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.

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.
