Battery for pyramid 105 amp

Not to disappoint you too much, but the 1000 watts advertised is just marketing hype. If your amp is the PB781X, it should have only a single 15A fuse on it. Your battery provides 12.5 volts when the engine is off, so at most, your amp draws 187.5 watts of power. Draws, not outputs. No amp is 100% efficient due to heat. When your engine is running, assuming your alternator outputs 14.4 volts, your amp's maximum power draw is about 216 watts. Again, this is what your amp draws, not what it puts out. What you should focus on is the RMS (continuous) output, not Max or PMPO. Those numbers are useless, unfortunately.
Your amp is rated to output 50 watts per channel at 4 Ohms, and 75 watts per channel at 2 ohms. This is when wiring your channels separately, not bridged. I did not see true power specs for your amp while bridged, but it's possible you'll just get the full 150 watts to the single bridged output. Do not attempt to apply a 1 ohm load to your amplifier, as you will run the risk of damaging it. It's not designed to handle a 1 ohm load. If you're lucky, you'll blow a fuse before the amp is damaged, but either way, there is nothing to be gained by attempting it.

It could be you have a fault in the Diode pack in the alternator you need to get this checked at an alternator repair center.

not exact, to charge apropiate needs 10% more than nominal voltage. if not, will not charge the batteries.
And the charger its very important because you can over charge the battery.An example,if you have a 12 Amps Batteries each one if you put it in series will be 24 Volts.at parallel conection will be 12 volts but the double of Amps.
At serial connection will be 12 Volts the amps will be the same but the volts will be 24.

The charger at 12 Volts must be 13.8-14.5 DC Volts and divide the Amps in Hours.
The charger at 24 Volts must be 26-28 Volts. to charge well.

The charger for 12 amps batt example must charge 2 amps per hour at 6 hours = 12 Amps.(2 Amps Charger by 6 Hours Charging= 12 Amps.(Fully Charged.
3 Amperes Charger needs 4 Hours to charge 12 amps Batt.
5 Amperes Charger needs 2 Hours charging an a quarter
All of this is at DC Current.

Luck.

Could be electrical.Bikes that have generator systems need battery induced.Unlike an alternator system,like a car you can jump start and the alternator will run with good spark to fire fuel.Generator type need battery induced,so battery must have correct amperage.Can test battery with a volt or/amp test.See what you have with bike not running,then running need about 20% more volts then the 6 or 12 volt battery states (about 14 volts running on a 12 volt battery.Know your battery life span & know that a new battery that year.Plus generator must keep battery charged.I like to have a good spare and also go for a glass mat battery especially if bike is ridden season related. Good Luck!

Check your batteries voltage you need at least 12 volts.If you don't have 12 volts then put the battery on a 2-4 amp charge for 6-8 hours.Then if the battery does'nt have 12 volts get a new battery.If your battery has 12 volts afterwards and still cuts off then your alternator is faulty.With the engine running your alternators power wire should show 13-15 volts coming out.

Hello, my name is Ben. Your battery is 12 volts. Here are the complete battery specs : 12-volt, 19 amp-hour, 270 cca.

If you are able to give some information about the battery, i can tel you where to get it. They are generally available. :)
