I have pioneer a1686r 350w & a6996r 650w speakers, joying front unit, also want to buy a subwoofer and amp. should i get one of these caps?

You should always back up you amps with a cap it stabilizes and protects all of you cars electronics and improves quality of audio

There's an audible alert for something since this cap has a buzzer in it's circuitry. anybody know why? says "notification safety sound alert" in desc

Yes, it’s for when the voltage contained in the cap goes under 10 if I am not mistaken.

how hot does this thing get?

Am running 1000 watts in my Subaru I don’t feel it hot at all!

can 2 be connected in parallel to get greater output?

Just buy a 5 farad of the same brand for $46. But to answer your question,yes you can connect these in parallel. Your can never have tooany farads protecting your system. You can only have like a 200 watt amp but have it connected to a 20 farad cap if you wanted to or four 5 farad caps.
