Nice amp but it clips when you turn it up.

    • Loud and Clean for the money
I have this amp in my car with 4-6.5's in my doors,2-6×9's in rear deck, and 2- 3.8" super bullet tweeters. ITS LOUD, I had to dial back a bit. I'd recommend this amp for kids and highs

    • Low budget amp, minmal clarity, save your money.
Garbage. 48 hours after install, this thing shorted internally, killing 2 channels, and shorting out two speakers. Sound clarity is about what you would expect from a $200 amplifier... But this $200 amplifier cost me $300 in speakers...

I need to first say my initial concern was travel space in my trunk, if you have a convertible or a small sports car travel space comes at a premium. That being said, I went with this amplifier because of features, size, layout of the connections, and customer service support after the sale. The Bluetooth connection works great, it may need some type of secure feature moving forward, anyone within range can connect to it. The gain is not that good, I was expecting more, it is noticeable, but it is not what you would expect, just turn it all the way up if you must. The bass boast is noticeable, again if you adjust it, make the necessary changes to your DSP or EQ, crossover etc… The amp feels solid and heavy, it does not have a “cheap feel” to it. I installed it myself because the install shops I called quoted me outrageous for prices just to install the amplifier. If you have a convertible 370z and you want to take this project on yourself, you can reach out to me via this message. I will do what I can to text you some suggestion and work arounds. I did not post my install on YouTube. To wrap this up, when Rockville makes an updated amplifier that has more power and gain, I will be swapping this one out for sure. If you are concerned about space and you need the Bluetooth feature go for it, you will not be disappointed. The Real Critic. ... show more

    • 8 Channel Amp
RCD/DVD Surround in my Excursion… 4 Channels (4 Way 6x9) in each door, two channels for 8” Mid-Subs in the third row, and 2 Channels Bridged for the Sub (12” Dual Voice Coil) in my Excursion. Sound is Phenomenal… Clear and Crisp from the Highs, Mids, Bass, and Subs.

    • Make sure you mark your wires before connecting to avoid any mistakes with your sound system
And affordable and compact amplifier that you connect with your phone without the need of a stereo in your vehicle, you connect your speaker wires straight to the amplifier
