Ok so not sure if this ever got answered but I have had a few of the 1300.1 Sedona amps, 2 of the 15" black ice and a few of the 12" BI subs.They all have been great. The amps put out A LOT of power. I had the 15's hooked up @ 1 ohm and it just about took the mirrors off of my 14' Jeep Grand Cherokee Overland. I used the hi/lo converter that it comes with to tie into my factory sub line and it was very clean, sharp and power full, every time. I also installed another 1300.1 in my friends truck, with the 12" and it hit just as hard as my CVX on a 1000.1 zx kicker amp that cost me tons more. I am no pro, but I do love music and installs. I have installed many many systems, for free for friends and I even tune it with an Oscope, so I do love music. Im sure if you get down to it spec for spec, it wont hold up to lets say a Memphis, but for the price it is amazing. Makes it fun again to play around with your system. I got the 15's for like 150$ shipped and the amp was $140 shipped. So with a $100 box, it was an awesome system for under $500.......
I will be getting the 7000.1 here soon to put into my 16 year old daughter 2010 Toyota Tundra and will be paired with 2 CVX 12's or a new 15" sub. So she will be a good test on how it holds up....lol
