I have little love for those Odyssey batteries. They are a lot heavier than an equivalent-power lead-acid lawn mower battery, and about the same size. And they drain really fast, hook up a laptop and a wideband to the system and leave the engine/alternator off for 5 minutes, the car won't crank. Add in the $$$ pricetag and ---- those things. Even $50-something for the exact same thing in generic brand is a premium.


MISTER PHILL.... what is the amp rating of those 5lb units, and might I obtain one? :)

Further, my stereo installer probably turned down the gain on my amp because he knows I'm a fat fingered hooligan, so I'm probably getting 75% of what I think I am.
