Is 2500 watts too much for a x12? (critique my setup idea)

[QUOTE="hispls, post: 8741550, member: 614752"] Yes. I was looking at some charts from my guy in China this morning. This is for a common """car audio""" cell 1C 30,000 cycles 3C 15,000 cycles 5C 8000 cycles This is for 50C max rated cells, already we see at 1/10th of their max rating you are shortening their lifespan! They do not go higher with published test data and who knows what this translates to real-world, but the conclusion is obvious, the harder you push these the sooner they will fail. I did not check for discharge graphs but if they're like any other battery I've seen performance also suffers as you push them beyond 1-5C Over-charging is a very real risk, your alternator will try to give everything it has when loaded down and I would advise to delete the front/AGM battery entirely if you're going to start getting into Lithium as they will only hurt performance. 4th order bandpass porting up through the rear deck (like Pop's video) is your best option to get sound up front in a car like that but it is not a simple project and would be easy to **** up or make something that looked super ghetto. Shitcanning the back seats and doing a B-pillar wall would be an easier project IMO. I also don't think 8 cube is quite enough to do 4 12s right and I suspect you won't have as much volume as you think you do, so might want to revisit that topic as well. [/QUOTE]
