Review on 🔌 BESTEK 150W Power Inverter DC 12V to 110V AC Converter with 4.2A Dual USB Car Adapter in Yellow by Darius Carraway

Plugging directly into a 50w RMS subwoofer (100w dynamic if that means anything) was too lazy and cheap to buy a separate 12v amp and lay cables there. Works great on a 10 amp fused cigarette lighter socket. No noticeable noise interference from the modified sine wave to the speaker, however you may have noise issues with a full range speaker, this is a subwoofer. Before you buy, remember to check your car's wiring diagram to determine how many amps your fuse will deliver to your cigarette lighter. From there you can determine how much current can be drawn from the lighter without blowing the fuse. Then buy an inverter of suitable capacity and you're done.
