I'm putting together a system with:
Mosconi One 70.6 driving a pair of Hertz Mille Legend 3" mids and 1.5" tweeters (leaving 2 channels unused for now)
Mosconi One 250.2 driving Legend 7" Mids (will be underutilized at reasonably low gain)
Mosconi One 1000.1D driving a single 4ohm JL Audio TW5v2
Nav TV Zen-V preamp
Helix DSP.3 with Director
The only other accessory I've added is a radar detector (Escort Max 360).
Car is a stock 2018 Audi S3 with a 140amp alternator.
I really don't think I need a secondary battery but I'm a little worried about the alternator.
The 1000.1D will do maybe 500W to the 4 ohm sub at the most.
The 70.6 will be pushing maybe 55-60W to each of the 4 mids and highs.
The 250.2 will be pushing maybe 150-175W to each of the 2 7" midbass?
Anyone think I have anything to worry about in terms of the electrical system? I listen to a lot of house and electro music as well as hard rock and other things like jazz etc. Should I reconsider an additional battery? Am I likely to damage the alternator? The stock system already had what the called a 700W amp running too many speakers.
Thanks for any input.
