I had a plate amp Die on my HSU VTF Subwoofer.. Anyone who knows hometheatre HSU is no joke in the Hoem Sub Dept. The plate was 300 watt BASH i beleive... was quited near 300 to Fix so I tried this A3001 out and was super impressed..But kept reading online how the FOSI is better, So I ended up changing out to the FOSI which now living with it for about 6 months... The A3001 was Far better and had the Sub Freq adjust.. I adjust my Sub out with My Receiver X over which is 80hz, but I think you can go lower with the Mini Amp

Providing smooth and dynamic bass, into a 2 ohm load no less. I'm impressed! The price and size could easily be taken as a lightweight contender, but don't be fooled- it can pump out the lows!

I freely design and donate hearing loops to local non-profits so that the communities they serve which have members with hearing impairment and hearing aids (like me) can clearly hear during their events and service to citizens. This amplifier, with its 2 ohm output, is a perfect amplifier for small to medium size hearing loops. My stereo doesn't have a sub-woofer, so I haven't used that feature, but the full-frequency output sure sounds great through the T-Coils on my hearing aids! I'll be buying more of them!!

Amp plate quit on triad sub used in my office. With this was able to have a working sub again. And not have to try and we'll or get rid of the sub due to a bad amp. If the need came up again, would buy again.

He comprado 3 amplificadores modelo aiyima a3001 para usarlos como monocanal en un avr que dispone de preout y así usarlo solo como preamplificador y procesador. Cada amplificacor es para una columna jamo c97II izquierda, otra etapa para el central jamo de la serie y la otra para la columna derecha. Además he usado otra etapa aiyima estéreo para los surround bipolares jamo c7. He mejorado muchísimo el sistema y he ganado en detalle, calidad y potencia. Mi onkyo avr es tope de gama y dispone de 180w rms en estéreo y estás etapas mueven más y mejor. También las he probado para varios subwoofer jbl de 12 pulgadas y un sellado jamo de 10 pulgadas y los mueve sin problema. Así que compraré una cuarta etapa para ese subwoofer. Las recomiendo pero cuando están de oferta.

This small amp provides packs a lot of puch. The sound quality is clean of distortion and bass is so clear compared to major brand. I was so impressed when turning on/off like there was never a thump or power surge that's will destroy you subwoofer. I used it powered my 8 inch subwoofer with custom build speaker box.

J'ai commandé cet ampli pour me faire un petit caisson de basse maison.Il rempli largement son travail.Je l'utilise pour une pièce d'une quarantaine de mètres carrés.Il est connecté à un sub de 250W RMS en 4 Ohms.Pour résumer, idéal si vous avez un sub passif et pas spécialement l'envie de le changer par un actif.

I have an old KEF subwoofer as part of my setup, and sadly the inbuilt plate amp recently failed (a well-known issue with these units).The driver and enclosure are still fine, so I was looking for an external amp to resurrect the sub. I already have an Aiyima T9 Pro driving the system (which is excellent), so picked the A3001 to do the job.Setup was straightforward, wiring the sub's speaker directly in to the 2 speaker cable poles in the rear (I believe the single RCA jack is for a different use as I couldn't get a signal this way).Setting the amp to sub mode just works, adjusting the built-in crossover to tune the sound.My only gripe is that the crossover and volume controls are stepped, but actually I haven't knocked a star off for this as realistically this is only a psychological thing.
