    Great 4 channel DSP

    Great sound if you want to add more power to your stock head unit. It may be a little complicated to install but its worth it!

    Unbelievably Good

    Checking this amp our for the first time, I was skeptical. It’s so light. It’s class D. It doesn’t require you to run 0 gauge welding cables from your battery. Frankly, it looked like something I would get from K-Mart. How wrong I was. This thing is musical. It’s powerful. It blows the doors off my truck while staying cool as a cucumber. Granted, you MUST run the DSP setup. Without it, it’s a nice amp. After running the DSP, which is trivial, this little gem will make you swoon. Buy it. Now.

    Super Easy Installation and Perfect Size

    I've never installed stereo equipment in a vehicle. This seemed to be what I needed to boost my aftermarket speakers in my 2020 Nissan Frontier. A 20-minute YouTube video and ordering the wiring harness off and had it installed and calibrated in less than an hour. Fit right behind the stereo in the dash so you don't even see it. I thought the aftermarket speakers were nice before, but now it sounds phenomenal. I had thought about getting a sub, but this got all the bass I needed from the 6x9 and 6.5s. Highly recommend if you'd in the market.
