Even if it is not a dual terminal supply despite what DYohn's linked pic shows, we are back to my first reply.
I can't see amp manufacturer's using a redundant dual supply topology - that requires extra circuitry in the amp (so that an input short on one does not fail the other). That adds a relatively significant cost at the expense of other risks.
And mere dual terminals for the sake of supplying dual feeds simply is not justified in typical systems. How often does the supply fail? And if it does, so what? It is not critical and can easily be fixed. A failure is usually a blown fuse or a battery failure.
To overcome that, a dual battery and distribution system is required, and is that justified (even if the amp itself does have dual redundant inputs)?
I have never heard of redundant supplies for car audio.
Lighting and other critical circuits may have - eg, my high-beam passing/flasher circuit has an independent fuse path and relay in case of main fuse etc failure. But that's useless if the failure was caused by a high-beam short (unless I have each filament on its own unique bypass supply and relay and individual normal-use relays).

Agreed. Even "dual mono" stereo amps gain nothing from redundant power supplies in the car audio world. In the home with noisy AC supplies, maybe. But in the DC world: just give them sufficient current.

i only notice dual terminals in high power amps that are really two lower model amps strapped together inside the same case. one example that comes to mind is an older autotek mean machine 4000.1D which is only two 2000.1D's built on the same PCB. i know a few older Orion amps that were like that too, the amps wont turn on unless both sets of terminals were being fed voltage.

I am going to assume that the poster was just looking at the speaker outputs which show two negatives and two positives.

No I never saw an amp with two positive inputs as in power 12v so I posted and asked how this amps works

The Power Acoustik BAMF 550/1d does have 2 4Ga inputs for power and ground.    Some older Rockford products have 2 as well.  I have repaired many of both with melted power or ground terminals.  In every case, the end user fed only one of the inputs. 

I have seen many amps with single power and ground that had the same problem.  In most of these cases, the power or ground wire was not of adequate gauge. 

Key rule of thumb, fill up the power and ground terminals.  If it will accept 0Ga.  use that.  If it will accept 4Ga., use that.    If it has 2 power and 2 grounds, fill them both up.

Yes, it only has one power supply but it allows using two smaller gauge cables because it needs the current capacity. Two cables of the same gauge create the equivalent of a single cable three numbers larger, so dual 4AWG is the same as a single 1AWG.
