Review: Muy bien sonido y una potencia aceptable. El amplificador tiene un tamaño pequeño adaptable a cualquier sitio. Lo único que destacaría en su contra es que los cables de conexión se quedan cortos. En mi caso me los tuvieron que sustituir por otros más largos, pero en general estoy satisfecho. Buen sonido Kenwood y calidad.
Review: Funziona da dio. Secondo me un buon acquisto

## Questions & Answers

**Q: Will this pair well with model KMMBT31BU?**
A: I am not a professional, but I have worked with home, car, and venue audio for over 25 years.  I say they will make a great pair.  If that head end has the features you want, then this little amp will give 100w max watts per channel over the 50w onboard.  It can pump out a very reasonable volume level with plenty left over so that the sound doesn't get distorted.  In fact, I wouldn't recommend getting anything more powerful unless you replace the speakers too.

**Q: Does it come with the harness pigtails?**
A: Yes and the RCA cables. Pretty complete. You will need a y connector on the RCA input side if you want to bridge the amp.

**Q: How many rms per channel**
A: 45 watts x 4

**Q: Ohm stability?Rms ratings @ ohm loads ?**
A: 4ohm

Surprisingly good for the price. I put this in my boat and what a difference! Much Louder, higher quality sound and adds a decent amount of thump for a 6" round x 4 channel set up. Exactly what I was looking for. Ideal for your mid-high range speakers imo.
