The consensus

What reviewers found

Synthesized across the trust-weighted source mix below.

Across the reviewers we read, the Taramps TS 400x4 is the polarizing budget pick of this category. At under $60 it is a Class D four-channel rated for 400W RMS, and YouTube dyno references in the signals back the basic power claim. Verified-purchase volume is large (1,536 reviews at 4.4 average) and one r/CarAV commenter is blunt: 'For the price I paid, I have no complaints, nor do I think you can beat it.' The disagreement is real and worth surfacing.

What reviewers liked

  • Very low price point with verified-purchase base of 1,536 reviews at 4.4 average
  • r/CarAV commenters confirm it generally meets or slightly exceeds its 400W RMS rating on dyno
  • Tiny footprint makes it a popular choice for motorcycles, ATVs, and tight installs
  • Class D efficiency keeps heat and current draw modest

Where it falls short

  • r/CarAV thread bluntly calls it 'one of the worst 4-channel amps' for sound quality compared to Alpine
  • Documented owner reports of audible hiss even with the gain set low
  • Specialist community consensus is that Taramps build quality is 'very cheaply made' even if power is honest
  • Sound-quality ceiling is low enough that reviewers steer serious front-stage builds elsewhere

Across the reviewers we read, the Taramps TS 400x4 is the polarizing budget pick of this category. At under $60 it is a Class D four-channel rated for 400W RMS, and YouTube dyno references in the signals back the basic power claim. Verified-purchase volume is large (1,536 reviews at 4.4 average) and one r/CarAV commenter is blunt: 'For the price I paid, I have no complaints, nor do I think you can beat it.'

The disagreement is real and worth surfacing. Another r/CarAV thread comparing it to the Alpine S-A32F is equally blunt in the opposite direction: 'the TS is one of the worst 4-channel amps I have ever used, the sound is garbage and it's noisy.' A separate thread on the TS400x4 specifically describes audible hiss even with the gain fully down. Specialist consensus on Taramps as a brand is that they are 'very cheaply made' but 'put out substantially more than rated,' which is a different value proposition than buying an Alpine or Pioneer.

For a motorcycle, ATV, side-by-side, or a second amp in a budget build where size matters more than ultimate sound quality, the trust-weighted consensus is that this is acceptable. For a primary front-stage amp in a car you actually care about, multiple high-trust community voices push you toward stepping up.

The JP84 400x4 amp, for $160 and then the taramps TS 400x4 for $80. I've heard many people say that the JP84 is a really solid amp and sounds great.

Taramps are good, just make sure to use a thicker ground wire, and quality ground connectors. I had a Bass 800 melt the ground bridge, simply ...
