Watts=amps*volts

I look at AH over watts, just for a rough estimate.

Actually neither for car audio. Reserve capacity is the magic number to look at. Ah is calculated at a 5 amp draw over hours until fully dead ~10.5 volts and they take that hour amount multiply by current draw and get Ah. So unless you want to power some fog lights for hours don't look at Ah.

i think they mean like what's a good number for reserve lol

c'mon now, if i was shooting an 8 year old, it wouldnt be MY 8 year old.

i recently got a Pyle PL1590BL and i was building an enclosure for it tuned to 25 hz. i didn't have any tools to cut a circle so i hit it with a big hammer.

An optima yellow top group 34 battery is 120 and a XS power D3100 is 240, obviously we know which is the better battery of the two, but those are the numbers to look at for car audio application.
