with the sfb 8K I'm going to be running it with 3 12s rated for 1,000 watts each at 2.67 nominal. Realistic power production might be around $4,500 to 5000 Watts. Still kind of worried that might be a bit much for my three 1000 watt subs is it true that turning the games down will lower the power to them? The 5k looks to make around 3k at that impedance.Beware of Droppin Hz. You will never get a reply from him after you buy if anything goes wrong.
10AH bank for 600$ is straight outrageous and even if it's a 100C discharge and 30C charge rated cell in there you absolutely would not want to be in that position. It'll probably outlast the warranty and it's certainly a convenient package but that thing is a perfect example of selling pixie dust and magic beans. Even the Toshiba SCIB cells aren't claiming that.
Best case scenario all of that marketing is 100% honest, then what? You have your 8,000W amp trying to draw 1000A, this battery (best case scenario) can provide that for half a minute and then your alternator (if you're lucky) is trying to dump 300A of current into it.... better hope that 30C charge rating is legit, now you'll need several minutes at max charge rate to get ready for another 30 seconds of reserve.
IF your application requires just a few seconds of reserve energy you would do better to invest in a super-cap bank. I believe you would do better by planning a battery bank with a bit of reserve in it as opposed to high C rating.
I did see in the SSA store they had a 40 amp hours already made in a custom case for about $5oo n 80 amp hours for about a thousand, ready to go w a warranty. That might be my best option
Always had great luck with SSA Aaron is awesome
