I was watching youtube video on it and it seems like the rockford does rated piwer but just runs very hot and I read reviews it shuts off.
The other amps wont work well with the W7 except the digital design. The W7 has to be wired at 3ohms and the digital designs amp does 840 @ 3ohms. The W6 has dual 4 voice coil so that I can wire to 2 ohms. The W6 is what I'm gonna go for. Great SQ sub and also it doesn't require a very big box
I have 2 of the rf t-1000.5 amplifiers in two different vehicles. They don’t shut off. Yeah they do run hot. Typical for a rf amp plus it is small. I never have had any issues with either one of them but I made sure they have plenty of circulation and I was concerned with the heat so I do run a amp fan on both of them. With the amp fan they stay at a more reasonable temp. One of them I run in my work truck. I run a regional truck and spend two nights a week away from home. That amp is on from the time I leave until I get back home. I fall asleep with it on. I’ve had it at least two years. Probably getting closer to 3 years now. If you go that route I’d just mount it so that it has circulation underneath and on top.
