i was excited before i opened and saw SKAR everywhere. thats an amazing price on that SAZ3500 though

per Vance Dickason adding stuffing can: 15% - 25% i volume increase efficiency as much as 15% potentially change moving mass of the system decreasing system efficiency damping losses reduce coloration due to reflections in an enclosure He spends 6 pages on the subject. You basically use formulas to calculate Q, then add or remove stuffing and recalculate.

ugh.. this is hard to answer because the question is to broad to answer so i'll attempt.. You have a working range for amps.. (which isnt concrete), and you have a working acceptable range for batteries' DOD cycles(depth of discharge). Typical working range of amps- 9-10v to 16-19v. So, let's say 10v-16v. That doesn't mean 10.4v, for example, is still fine. Under maximum potential output power, it will be pulling the most current. Adding the fact of low low low voltage, the time it will take for amplifier failure will increase greatly. So an amp can still die within it's operable voltage range just stressing over current draw. It's based on time. Time can be a second to whenever.. It's the context of the scenario. Batteries' DOD. The DOD cycles are higher with less discharge. Discharging 20% all the time and recharging will net the battery much longer life, many many years. AGMs have this typical life expectancy under lightest duties- 8-10yrs average til 60% life or 20yrs under complete failure. This is probably best best best case scenario though. Every time you cycle a battery, discharge then recharge, it potentially prevents it from resting at the same voltage it did from the beginning. After several hundred cycles or a couple thousand, it will only rest at 60% of what it used to. Voltage levels are not linear so 60% of 13.0v may be around 12.3v, for example, best potential. For daily usage, try not to allow your battery to have dynamic peaks where the battery drops below 12.0v. If it does, it's not bad, just, harder on the battery. Batteries subdued to drops at or below 11.4v for continuous usage over period of months are going to have a much shortened life due to abuse and high DOD.

Your goal is the same as mine.....You just made me feel really good about my purchase...Thanks man.

Not surprised at amount of Skar as B-Stock or opened. You gotta open the box to make sure they weren't shipped 2 amps to a box with no packaging.

I hate the angled ones.

Paint looks great. Eff a vinyl wrap. Who would do that....

I'm hoping to get on a new icon or the SAX b-stock

I was told you could tighten the angled ones better.
