This says that the sub has a fuse built in to protect it... anyone ever hear of this?

I've never seen that before. I think it's a good idea, but will most probably not prevent you from killing the driver.

Maybe its for the Rookie Noobs that dont do there wiring corectly, or its a faulty design and they did that to save there reputation? who knows.

never seen a sub with a fuse built in but I've seen plenty of speaker leads fused to protect the amplifier and the speakers, and some amplifier harnesses even have fused speaker wiring as an option (Orion)

I didn't notice that on the G5's. In the pic I normally see, it just looks like a sticker or something on the side. They didn't mention it in the info either.

i dont know, when you look @ the back view, there are def. 2 fuses there

What amperage are those fuses? They look like 10a. Looks like no burping at comps lol.

10A @ what, 115VAC or 12VDC?

remember the speakers are high voltage AC circuits.. not high current DC, like the power lines.

The Kenwood has a 25 amp fuse which means with the voice coils(3 ohm) in parallel you need to start worrying about the fuse blowing with about 1000 watts.

P = I^2*R = ((25)^2)*(1.5) = 937.5 watts

That fuse would do very little if the vc's were in series. You'd need to provide over 3750 watts for it to blow with that setup(R=6ohms).

I know. More geeky math.
