You also stated that 3) the individual burping with a couple of thousand watts is getting square waves AKA clipping. While that may not be a big deal during his short burps, supplying such a signal to a system used on a daily basis is not healthy for either the sub or the amp. Also, yes, it is possible not to drop below 12.6v on music... with an incredibly stout (expensive) electrical system. Also, while he will not see 2600 watts continuously, there will be spikes in the draw depending on the frequencies being played. I agree with what you say as far as burping is concerned. However, for a daily system above 1krms, a stout battery is needed in my opinion. I propose that we agree to disagree lol.
1) Um. That protection circuit must be below 11V? When you're vehicle is off the battery value can be ~11.8V. What is it down line? Again...I'd like to redirect you to the idea that if your engine is running then our 120amp alternator is sufficient.

2) A draw that serious? You were talking about "quickly discharging"...now "a draw that serious"? If the battery kicks in at 12.6V...and you're dropping below 11V...now you're exceeding the alternator and battery together? In what world/environment does that occur? I'd like to point out again....your amplifier will never approach 'rated' RMS, let alone "a draw that serious"

3) In a mathematical sense, a square wave(burp) and "clipped" signal are essentially the same.


You haven't addressed the issue at hand. I'm stating that the op's setup is well within the threshold of our 120amp alternators. In addition, if the engine is on...the battery will never supplement the vehicle's electrical system.

Ever seen a vehicle running without the battery?
