For the price this is the best deal I've seen. 66 bucks shipped for the amp and wires. I installed it in about 2 hours, hardest part was pulling up the panels and getting the wires through. The rest of the wiring was painless, they give u everything you need. I would highly recommend the add a circuit for tapping in to the fuse block. No wire splicing, super easy to take out later and worked well for me. About the amps performance: I hooked it up to a single 10 inch kicker cvr (Silver, older model) recommended for 400 max rms. I'm running this amp at 4 ohms, not 2. What I've found is that I have the setup that is recommended for longevity and health of the sub system. The amp is over powered for the sub, so I have to turn the amp down some, reducing the work load of the amp, and it's in 4 ohm so that dramatically reduces the workload from the start. The subwoofer would become distorted at high levels so I turned down the output and now I've found the sweet spot where it hits really hard but also clean tones. I haven't installed the remote control yet, don't think I'd really use it. It does work but I think I'd just rather have the bass up all the time, maybe later I'll get tired of it and want the quick adjustment feature. I've played really loud music for almost an hour with a lot of bass and gone to the trunk to check how hot it's getting and it's barely warm. Very impressed with the setup. I think getting a quality subwoofer, something that can handle all the watts you're throwing at it well is more important than the amp being super accurate and high quality. Time will tell how this amp holds up but so far it's been a great fit for 1 10 inch at 4 ohms. And 2 ohms I'd be willing to bet it would push 2 subwoofers well. The size of the amp made it easy to screw to the back of the 10 inch subwoofer box. It's made for a pretty clean install. Then I made an L bracket and screwed in to the floor of the trunk and the box, it doesn't move at all when driving. Keeping the trunk space usable was very important to me, so a little 10 is very noticeable, shakes mirrors, u hear it outside the car some, and is a great addition to my 2012 civic which has a loud factory setup, yet it doesn't take up too much room in the trunk so it's the best of both worlds in my eyes. Oh one note, the amp barely bumps at all with the bass boost option turned off. But once I turn it on it claims an 18db boost and it really comes alive. I tapped in to the rear speakers high outputs for my speaker input. Made it easy to run less wires(no rcas) and I didn't have to pull the dash apart to get to the back of the head unit. The amp gets a crystal clear signal and handles the high output levels very well.

This is a awesome amp for the price, i am using it for a budget sub setup for my car. The setup is straight forward, and it comes with the connector for your door speakers if you want to power them from the amp

I purchased this amp with a gift card to power 2 Kicker CompR 10" 2 Ohm dual voice coil woofers in a sealed box running at a total of 2 Ohms. I listen to alot of R&B, techno, and deep heavy bass music in a 2017 Mazda 3. I initially purchased this amp as a very cheap (basically free from a christmas giftcard) beginner amp with the intention to purchase a new amp once this one failed..... WELL, 2 years later and it is still going strong as ever!! It works and provides what it is supposed to do, MORE BASS! ****Nit picks about the amp**** -It is no where near 1100 watts! Alot of reviews show this amp really caps at 200 watts. So, at most 100 Watts per 10" CompR woofer in my set up. It has been great and plenty loud enough for just some extra bass support. -I found I kept driving the gain a little higher trying to get more output but this amp just could not dish it out with out distorting. I only say that to be mindful that that this amp will not be rattling the neighbors windows or really even bothering the other cars next to you. I will be audible outside the vehicle but nothing really aggressively obnoxious. -It is a class A/B amplifier so it does draw more power when turned full set volume , but only enough to make my headlights dip a small amount very quickly. So, If you are wanting just some extra low end support with out spending to much! I would 100% recommend this! I only rate it 4 stars because of the false claim of 1100 watts from BOSS, not really any issue with the seller or product.

Was relatively simple to wire up. I piggybacked it off the factory Sony amp, using the violet/red +12V in wire for battery power and connecting the remote-on trigger wire to the brown/green wire going into the nearby trunk light. Ground went to the driver side rear seatbelt anchor point under the cushion, which just pulls straight up and out of the way for easy access. It’s a Torx T-50 bolt. Wired the High Input harness to the rear speaker out wires coming from the factory Sony amp module. Works like a charm. I originally installed this amp using the factory subwoofer (just one of the 2-ohm voice coils, not using the other), and it was leaps and bounds from how it sounded with the stock amp. It was so badly underpowered from the factory. However, the tiny stock sub still fails to cleanly reproduce anything under 40Hz without being overpowered by the amp. I solved this by installing an NVX custom 10” sub (found on Amazon as well) and now the system sounds amazing, just how I would have hoped a premium Sony system would right off the bat. Very deep and clean bass, punchy and very tunable with the adjustment knobs. I didn’t use the remote amp level knob, but I have the amp tuned just where I like it with the head unit “Bass” level at 50%, so I have some adjustment through the factory stereo. Great amp.
