IR400.1 2 Ohms 1 Channel IR 400 Watts RMS Amp Class D Mono Full Range Amplifier

Awesome compact amplifier. You must have the proper voltage for quality performance.

Perfeito

Works amazing with the 10” kicker comp in my father in laws truck.

So far this is one of the best amplifiers I've used in recent years. I was a professional installer back in Circuit City days, and have installed many different amplifiers over the years. I have gotten back into it in recent years and have had the chance to play with some of the more well know brands (Kicker, JL, JBL, Pioneer, Skar...) and this little amp will hang with them all day if paired with a good speaker. I have it setup in my wife's Jeep running a single Skar VD-8 D4 in a custom enclosure. It took a couple of weeks to break in the sub but now that that is done, the combo is amazing! At Jeep meetups, I've had people ask me what I'm running only to be confused that it's a single 8 inch sub. I have the amp mounted discretely under the front seat and the gain set at ~ 50%. The source is a Stinger HEIGH10 head unit with 5V pre-outs. For the cost of this amp, I will be buying more of these for future projects! Highly recommended!

Box was received damaged and the seal wad broken as if someone tampered with it. But the amp was in perfect shape!. Now for the real review. I originally had a kenwood excelon 2 channel which put out some good sound and sound quality was on point. But it was not loud enough to be on the harley. So i took this on a chance. I was going for 2 channels. But they had a 1 channel to create a 2 ohm output. The size is nice. Comes with high level input. Did a power up test and works!! Decided to test the amp out on the harley. At first i thought the amp was DOA, but nope i cranked the gain up got sound then started messing with the LPF and HPF. YOU have to adjust all 3 to get the sound you want. By god this thing is plenty loud!! But im sure i can push my Hertz SPL more with more power. Will write a 2nd review once it is completely installed and riden to rate it. The 4 stars is for the AMP, the minus 1 star is for handling of the package. Ease of installation will be fairly easy. I need to build a custom amp rack to hold the factory amp and this little guy Value for money for this price, you cant beat it if you are on a budget. PERFORMANCE: Cant talk about performance yet once I ride the thing to full potential.
