Review: awesome - sounds great !!
Review: Worked good til it didn’t - Amp worked great for the whole 2 months til it caught on fire. Professionally installed wiring and amplifier. Wiring still great and amplifier stays in protect mode after it filled the cab with smoke. Bought in November and first of February took a dump.

## Questions & Answers

**Q: the sia 2500 and the sfb 5000 are about the same price. which is the better buy**
A: 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

**Q: How many channels ?**
A: It’s a monoblock so 1 channel

**Q: Are the power and ground inputs 0 gauge?**
A: Yes, they are
