the sia 2500 and the sfb 5000 are about the same price. which is the better buy

I just purchased the sfb 8000d and i didn't realize it when i bought it but it has dual power and ground inputs to make it operate. I also heard on the 8000D that you need a upgraded alternator and at least 3 batteries total because it is very power hungry. I am going to sell my 8000D and purchase the SIA 2500. If you want to run dual power and ground inputs on the sfb-5000D then go for it. You may need an extra battery and alternator upgrade also

It’s a monoblock so 1 channel
