how long can i....

[Justin]

hey, just wondered how long i can sit with my engine off, but my stereo on, with my sub running? i am using a 450w amp and 1000w sub, plus 6*9s and front components (if that makes any difference!?)

Thanks in advance!

What rating is your battery in Amp Hours?

 

[Pete]

HU Power Rating?

 

[Justin]

HU is 4*52 Watts, is that what u mean?

ill just check the battery

No you need the current rating like ....mAH

 

[Justin]

it says 43Ah, is that the one??

4*52=208 mpo (about 104 watts)
104/12= 8.66amps
450w mpo = 18.75 amps
450w rms = 37.5 amps

 

[Justin]

yeah think the amp is 450w max, and the HU is 4*52W.

its not that i sit with the stereo on a lot but just incase....

 

[Dink]

probably pull about 35 amps at full tilt
but just listening normally probably last about 3.5 hours

is that right?? a lot longer than i expected, didnt think it would last more than an hour!!
