If you've never heard of a power cell you've apparently never been anywhere around car audio. Look at ANY competitive system, and if there not running multiple deep cycles they have power cells, which is basically a deep cycle battery that you add on to have stored power, like a cap that actually works basically. Don't dis it unless you know what it is and how it works, cause it works, and thats all i know. My lights dimmed with a cap and now i have plenty of power for everything with no issues. And on top of that i don't run enough to upgrade my alt so why spend 300 on a alt when i can spend 100 on a power cell and be done with no issues.
