So far it’s been an awesome amp! Works great and very nice quality. Easy to setup. Running it with 4 of the RKL80 speakers and they sound better than the Bose speakers at 1/4 the price

Wow. Just added the amp to existing stock stereo. Pretty much plug and play . No extra sub and wow did it wake up the stock JL m55 head unit. Full range of sound and loud. No need for a sub.

Let me start with I don't write reviews unless I'm wowed and saved me money. I had an issue with my amp, and the customer service team was incredible! They not only provided a full replacement but also took the time to explain how to prevent similar issues in the future. Their proactive approach and willingness to go the extra mile made me feel valued as a customer. Highly recommend Rockville for their outstanding service and commitment to quality!I 1. Full Replacement - This shows Rockville stand behind their product and are willing to make things right without hesitation. 2. Educational Support - Offering tips to prevent future issues reflects a genuine concern for your long-term satisfaction and product care. 3. The Proactive Approach - Rockville didn’t just fix the problem they helped you avoid it in the future, which builds trust and loyalty.

I installed this on my Pontoon Boat with 8 - 4 ohm speakers. Wow, does it sound good? I learned a lot in the process. My head unit distorts at about 75% volume. So, I replaced my very cheap head unit with an Alpine receiver, which has no distortion at 100% volume. Then I tuned the amp with a DD1, and oh my gosh, what a difference that made. People can hear me on the other side of the lake. The 3500-watt label is a little misleading. On mine, the amp is pushing about 73 RMS watts per channel at 4 ohms or 584 watts total with my 8-speaker setup. I highly recommend this amp, especially at the price.

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.
