Review: Lots of power - Great product works even better than expected... thank you
Review: It Works!!! - Okay I purchased this product knowing full well I was getting what i was paying for, a cheap amp. But if it was even half of what it said it was it would do just fine for me. I have 2 subs, one is a 10" and one is a 12", and they are both DVC 1100watt (400 RMS). At first I wired the subs in parallel and gave both subs their own channel (2 channel amp), as I thought this would get the best result. It did get them going but it wasn't "rattle the car" strong which i know these subs could do. Then I did a little more research and wired the subs in Series, then bridged Both subs together (both sub Neg- to 1st channel Neg-, and both sub pos+. to 2nd channel pos+) and OMG. This Amp is definitely worth the money. All the people that say this thing barely moves their sub.... Didnt hook it up right, simple as that. Do your research, find out the best way to wire your speakers to the kind of amp you have to get the most watts from it, Get the right Gauge Amp kit for your amp, and with this 5K watt amp, a capacitor is needed. if you did it right you will know. The most i have ran the amp in one session was an Hour and it was barley hot, next trip i take i will see how long it takes to over heat. This Amp isn't Fancy and doesn't have a bunch of lights and cool modern looks, But I would trade all that fancyness for a few more watts and a solid amp, which is exactly what this is. Thank you desertcart, TY Pyramid.

### ⭐⭐⭐⭐ works okay
*by S***Y on April 12, 2014*

I was kinda disapointed the right side negative terminal does not work I think the wiring in the back of the terminal was fault so I just bridged the 2nd sub with the 3rd and 4th the 1st sub on the left side terminals worked just fine it pushes so much power I have 2 kicker comp cvr 12s rated at 1000watts and 2 15in pyle blue waves at 1500watts each and slams way to hard even after adjusting it. Quick tip though that i did to make more power out of this amp pull the 30amp fuses and replace them with 50amp you allow the amp to draw more power but be warned you will need an extra battery and at least a 2.5 to 3 farad capacitor.
