Sundown Sia 3500 vs. the Taramps Smart 3K comparison

This article is meant to educate you on the differences between the Sia 3500 D vs. the Taramps smart 3k. Before we start, I want to let everybody know that I am not siding on one or the other, just a general overview comparison. The Fullbridge market, in my opinion, is nothing more than a Cost-Effective Way to save money on power, and there isn’t anything wrong with that at all.

What we know about the 2 amplifiers:

  • Each one is full-bridge technology, aka Brazilian.
  • One is made in china (sundown), one is made in Brazil (taramps)
  • Sundown SFB Amplifiers will phase out, and SIA Amplifiers will be the successor.
  • one comes with a bass knob (sundown) one comes with indicator gages (taramps)
  • Both have smart/intelligent technology designed into the amplifier.

Conclusion on specs with the Taramps smart 3k, 3000 watts at 12.6v at 1 and 2 ohms is really low, like scary low.  The signal-to-noise ratio is lower than sundown’s 108dB rating. On the bright side with the 12.6v ratings, This also means that they will probably do more power with better voltage. It is speculated that they are .5 ohm stable, but after talking with repair techs for taramps they really are not.

Reliability & Warranty

Sundown has shown its reliability over the years is amazing, and they stand fully behind their product.

Sundown Audio gives you a 2-year warranty, and if you are honest they will warranty your amplifier no questions really asked, do not run amp below 1 ohm.

Taramps warranties for 1 year, it’s not too clear on the terms,  reliability isn’t great just speaking from what I saw at my buddy’s house who repaired amps for them for many years… but the amplifiers are getting better with time!

Conclusion:

If you have the money, get sundown SIA 3500, if you are on a budget get the smart 3k!
