If my car's engine is off and i'm using my car stereo, listening to radio or my CDs, wouldn't it drain my battery? I know it would if i use it for a week ...but how about around an hour? I don't have an amp; just the HU, changer and the 4 stock speakers.
Follow-up question is, when would i need a separate battery to power up my car's sound system?
Depende gaano ka-luma na baterya mo... 1 hour hindi siguro... Tsaka wala ka namang amp... last time it happened to me, may amp na low power lang, kaso luma na battery, and we were listening for like 4 hours, kahit low volume, ayaw nang mag-start. Buti na lang may tumulong magtulak.
