SOURCE: my subwoofers cut out
You are most likey running too much power from the amp to the speakers.. you might want to try just notching the bass down a notch or 2.. just enough that the bass will hit

SOURCE: AMp keeps blowing fuses
When any amp blows fuses, this indicates that something is drawing too much current. The most common cause are components in the output stage and driver stages that have become defective.
On the amp that is blowing the fuse with the volume being turned up, this means that the output stage is partially working. The short or over-draw of current must be in the output stage, or what is loading it. It is possible in this case that a crossover in a speaker unit is defective, and is drawing too much current. I have seen this with especially sub-woofer crossovers, and the driver itself. Subs pull a lot of current because of the amount of drive power required to have very strong bass sounds. Other than that, this still does not rule out the possibility of the problem being defective components in the amplifier.

SOURCE: car amp blows 12 volt wire fuse
the wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse

IT MAY MEAN THAT IT TAKES (2) 25 AMP FUSES
IF YOU HAVE THEM OUT SEE IF IT SAYS WHAT THEY ARE OR OPEN IT UP IT MAY SAY IT ON THE BOARD OR THE FUSE HOLDER OR LOOK @ THE SPECS ON THE AMP SEE WHAT THE TOTAL CURRENT IS YOU CAN ALWAYS START WITH A SMALLER AMPAGE LIKE 10 -20 AMP FUSE ALWAYS GO SMALLER

Since you changed the amperage of the fuses and the cable, you allowed the internal problems of the
amplifier to get worse than they were before the original fuses started blowing.
A fuse is a safety instrument that blows instead of your amplifier.
The problem is NOT the fuses frequently blowing, as such events warn you of internal problems with
the amplifier which you should have had serviced at the time to prevent them getting worse.
It is very much like the persons who replace the fuses in their household wiring with pennies, to prevent
frequent fuse replacement only to have their house burn down from overloaded circuitry.
Service your amplifier immediately.
Revert to the original amperage on all fuses in your vehicle to prevent a car fire.
