no. do your big three and get good wire and youll be fine. just dont expect to play on full tilt for a long time.With 1200 watts do I need a separate battery
depends on car, but as someoen else posted toyota stock electrical is very finiky when it comes to amps. i just kinda thought about it, my girls camry 105 amp alt prob same as urs, didnt like 1000 -1200rms untill i put the battery in the rear.hmm I can play all day long with my 1700rms amp at .5 no problems stock electrical
the link he posted is $105 for them ^^dodge 5.2 ltr no clue what size my alt is. $100 for a battery is sort of cheap budget
