JVCKs-dr3005d Drvn Dr3 Series Ks-dr3005d 1,000-watt 5-Channel Class D Power Amp

can a universal bass control knob be installed on this amp?

So my fuses are good and it has power both positive and remote wire, grounds are good but amp won’t turn on I’m guessing mine blew?

Can you run a 2 ohm sub on the 5th channel? Box says 4?

Does this amp come with the bass control knob ?
