- Reviewed in the United States on September 30, 2023Style: KAC-M1814Verified PurchasePurchased this to amplify the standard door and tweeters in my 2022 Tacoma. The compact size allowed me to install it right underneath the stock head unit. The wire harnesses that come with the amp are nice and long.

- Reviewed in the United States on January 8, 2024Style: KAC-M1814Verified PurchaseUpon tuning the gain on the amp. The amp was suppose to get a clean sound at 13.4 volts, but instead it was even getting a clean sound at 14.2 volts. I was impressed and happy with the way my highs and mid sounded. I highly recommend this product for anyone looking for a compact amp with a true 45 watts RMS with clean power.
- Reviewed in the United States on June 2, 2024Style: KAC-M1814Verified PurchaseI've had 200+ watt Pioneers installed for about a year with a Kenwood head unit, sometimes when playing content from my phone I really had to crank the volume up to hear it well enough. Now with this amp connected, I barely need to go above 25% and it has fantastic audio quality. I've added the Kenwood compact sub to my setup so the Pioneers handle the mids and highs (and some low Hz), the compact sub handles the lows - all setup using the crossover in the head unit.
You really have to tune your setup if you expect this to sound good - go through your head unit settings, set the speaker size, distance, etc... Don't leave everything to default. I set the line sensitivity at about .3 (which is about 65-75% turning of the dial). HPF off so I can change settings on the fly at the head unit.
Oh and the size - this thing is so compact, I was able to tuck it under the dash behind the 'ol glovebox.
Everything you need is included, RCA cables, wiring harness, even some zip ties.
Like I said, when you tune it against the settings in your head unit, the audio quality is fantastic.

5.0 out of 5 stars Small but mighty
Style: KAC-M1814Verified PurchaseI've ordered several of these for a stereo kit that I build for an obscure vehicle, and I have been impressed time after time with these units. The 4 channel setup is perfect for powering any speaker set you want to hook it to, full range of gains on volume control and bass, and the price is just right.

5.0 out of 5 stars Buena potencia y sonido.
Style: KAC-M1814Verified PurchaseMuy 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.
