Hey I’m currently doing a car audio install in a 2018 Kia cerato YD and I need some recommendations on that to do I’ve done some installations before but none with a dual battery set up I’m planning on using a 200-250a alternator and a slimline 170AH AGM in the back I’ve heard some people say just use a isolator whilst someone from a car audio shop says to use a regulator or Dc-dc charger I’ve looked everywhere for a reg or dc-dc that is 200-250a to keep up with the power draw from the 2-3kw monoblock I’m planning on getting i already own the battery and the sub but no idea what to do after the advice that if I don’t use a dc-dc or reg my battery might get too much charge and go short circuit and act like a welder so no idea now what to do idk if I’m allowed to post links I’m new here link to the alternator: https://www.powerbastards.com/proddetail.asp?prod=14962-250-HD1-1 theres also a stinger alternator that’s a 220a but I don’t have a link it would be custom made Cheers Rick

Hey... I'm bored at work, so I might post something up kinda useful. I was aiming for a mediocre audio setup, and didn't want to spend big coin on audio wiring. I ended up settling for Stinger 6 Channel RCAs ($55 from eBay US, delivered) and some 5 core trailer light wire ($12 delivered off eBay AU). No point spending massive coin on cabling for just Vifa speakers & Jaycar Precision speakers. So here goes... If you ask why I used duct tape? it is because it's not easy to cable tie down flat cable. Also the headunit wiring done by the previous owner was "ok-ish" so I left it as is, just chopped the speaker lines up and connected it to the trailer wire. 5 cores, 4 for speakers, 1 for remote. Works a treat! I know, it's a crappy 1x preout deck, will be changed soon after my trip

Wanted to buy moulded sub box as per the attached image. Prefer box suitable for 12" sub, but not that fussed if another size. It's a series 1 if that makes any difference. Located Adelaide SA, willing to pay postage if a reasonable rate from interstate.
