Your diagram will be: Subwoofer - Amplifier - Source - Power.

Pwede ba "until sawa" ang playing time? This will depend on your power source.
- With the engine on, your amplifier gets its power from the alternator given that your alternator can handle the amperage/power consumption of your sub. How long can you play will depend on how much gas is in your gas tank.
- With the engine off, your amplifier gets its power from your battery and how long can you play will depend on the amount of power stored in your battery.

Hehehe, personally, I can only play my system at a concert-level-loud-inside for around 3 hours lang. Reason for this is that my subwoofer's amplifier will go into thermal protection afterwards because it's too hot and I'm hitting 90 Celsius inside it (and around 65Cs on the processor nearby).

There's only so much you can cool down when you have 2kW of Class A/B power on-tap for your subwoofer so far this only happened 2-3 times a year lang naman (usually if heavy traffic/deadlock). Most people don't really worry about their heat generation though since most subwoofer amps nowadays are efficient using Class D topology designs.
