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

Muy buena recomendada

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.

Just like what others said: came FAST (same day ordered actually!) - it's tiny - fit in my hand basically - puts out crazy power for being so small - someone else mentioned the GAIN knobs are very sensitive - just a little turn and it seems to crank straight UP pretty high - wouldn't mind it being a more gradual crank. Also, the screw connectors are a smaller form factor than the typical size. Power and Ground should at least be able to accommodate bigger connectors especially since those tend to be higher gauge wires (I'm using 10ga - should probably be 8ga but good luck jamming that into the space!) I basically screwed in the big connectors and let the force of driving in the screws reshape the connector. All the speaker and remote wires I just used smaller connectors that I had. This was my mistake and not the product's fault: I also messed up ordering this because I didn't pay attention to the speaker INPUTs. I was previously viewing the BLACK version of this, which had a dongle for connected "high" side wires, like for after market radios. Then I saw the WHITE one could be delivered same day so I jumped on it! LOL... Haste is Waste folks! So I had to make some wire-to-RCA cables. Make sure you note that if your radio doesn't have RCA but just straight wires for the speakers that you'll probably want the BLACK version of this. Otherwise - 2 days in and they sound great. I still have some tweaking. I have to started the car yet as I've been doing all this off a battery charger on the car. I'm curious if I'll get the alternator "whine" as someone else mentioned. I will update this if I do. Check the date on this post and if about a week or 2 has gone by, then it's good.

Very good amp for it's small size. I have it running on Channel 1/2 a single Pioneer 6x9 in a sealed box The Taramps is feeding it 200W RMS @ 4 OHM bridged & it's screams. & On Channel 3/4 I have it running the walmart special 10" Kicker sub powered in a wedge truck box (The original built in Kicker Amp died so i discnnected it from the sub) So the Sub is actually is 1 OHM & even though the Taramps isn't rated for 1 OHM I have it wired at 2OHM stereo on the Taramps & it still rocks hard (Only cuts out on close to max volume sometimes, so the protection circuit works good)
