I bought this amplifier on a whim. Never heard of this brand before. So I took a chance. And boy was I surprised. I have two 12 planet audio subwoofers. 1800 watts each.Wired to two ohm's coming out to one channel. My gain is set at around 30% and it hits extremely hard and the clarity is unbelievable. we took it up to a local competition shop and put it on a decimal meter fine-tuned everything in and I'm heading approximately 140 decibel with no problems. This amplifier it's just as well if not better then my Orion packing 5000 RMS on for type r's and I'm heading in the same decibel range. The Orion amplifier 5000 RMS true power and it cost me about $1,300 and no 700 for the subs and box. The shut up I have in my other vehicle is the two planet audio 12 inch subwoofers at 1800 watts a piece and this little 2000 watt amplifier prayer total cost of under $180 please just as well as my type R's do.And I don't even have it turned up it said about 30% and I was very surprised by the performance of this off the wall amplifier. Now one thing I know is stereo equipment I've been rocking subs since the late 80s. I know people get a laugh out of it when they pull up to a stop light and hear me and I roll the windows down because they're tinted and they see a 60 year old man sitting there just pounding the hell out of them subwoofers. I get a lot of thumbs up for that one. I took this keeper set up for the planet audio and the amplifier to a competition 45 people and I placed second on this system I placed first with my other vehicle which has the Orion in the type r's subwoofers in it both were hitting in the 140 to 160 decibel range which if you know stereo equipment that's enough to blow your eardrums out permanently. That's why I have everything on a remote. Hahaha. Take a chance the shut up subs were eighty bucks for the pair amplifier was around $70 dollars if I remember right and I have the bucks and it's sealed box not a ported box. And I can't say much about how surprised I was its performance of this under $200 sound system. even the people at the competition couldn't believe what I was running and placed second. Now I'm not all that enthused about having it heard two blocks away but it can be I'm mainly in it for the clarity. And it is extremely clear and loud and I would recommend this setup to anybody just wanting to start out or even upgrade to it. It's an unbelievable little system for the priceThank youWilliam Hart Jr.
