[QUOTE="Oldbasshead, post: 8866708, member: 688756"] 2019 Mazda 3 sedan. Stock 130A alternator. Big 3, done with 1/0 OFC. Stock lead acid battery but looking at AGM. 1/0 single run of 15' OFC from battery to amps. Voltage drop is minimal but can fluctuate +/- 1V with heavy bass drops. No light dimming but 1V does seem a little excessive. Possibly bad ground? Gear currently is Memphis 1500.1D running at 1 ohm to two Skar EVL 12's, subs and port facing at backseats. I tried so many variations and this gives me the best bass response to my ears and zero trunk/license plate rattle since majority of bass is in the cabin. Sealed that up best I could and it sounds surprisingly awesome. I also have a Kicker 800.1D that I would like to run to a Kicker downfiring solobaric in a factory box, probably 2 ohm, so >400 RMS? Rest of my stereo is factory Bose premium, so not upgrading it yet, but would like a little more mid-bass. Hence the little Kicker. Only place for it is in the trunk which is fully soundproofed with Kilmat. Ideally not looking to upgrade to HO alt and would prefer to run it all from a single battery. If I decide to go 3K or bigger, then this conversation changes. But this is a daily driver, so I'm looking for some power here and there, but SQ with a potential for a kick in the face is my goal. Am I being reasonable here for a mostly stock electrical? [/QUOTE]
