would completely depend on what kinda computer youre using.
Just was wondering is someone could give me a estimate time on how long I could run my carputer & amps with my car off with my optima yellow top.Just say a have the volume cranking and pulling about 3000 watts (amps are 3300 watts total) plus the inverter for the carputer.
I know I will not have it at full volume but just was wondering if I was at 3000 watts what time am I looking at?
Are we looking at minutes or 1 hour etc..
sorry, wattage claims from amp manufacturers are usually all over the place. I wasn't going to assume that the figures were accurate.
Regarding how long...
I had a Stinger SP1700 battery in my car running a US-2000 amplifier (that's 2000watts RMS, NOT PEAK mind you) and I ran it for 4 hours with the car off, at about 90% volume to burn in the speakers (4 12" Eclipse 8700s).
Should give you an idea. However, this was a new battery as well with proper wiring, etc.
Older batteries will vary as well.
And seeing how he's using a deep cycle battery, it'll depend on when the thing was cycled last.
