[QUOTE="Doxquzme, post: 8864058, member: 689267"] The HO alternator is going to provide extra current, not storage. Using a large AGM under the hood and Li-on in the rear would be the place to start. Something like this: [MEDIA=amazon]B08LQ27L6Y[/MEDIA] Has all the distribution connections you;ll need, awesome addition to any high powered system. You might not even need an upgrade to the Alt, with a good Li-oN setup in the rear. As for speakers, bail the rear deck as having powerful subs in the trunk means you have to isolate the rear deck speakers and there's no real benefit if you are using the rear doors for fill anyway. I would consider an 6 channel DSP amp like the Helix, Sony or AudioControl units for amplification. Something like this: [URL unfurl="true"]https://www.ebay.com/itm/355191446605?mkcid=1&mkrid=711-53200-19255-0&siteid=0&customid=link&campid=5335951755&toolid=20001&mkevt=1[/URL] 125x6, drive front 6.5's and tweeters with 4 channels, a pair of coaxials on passive in the rear doors then the sub out to your HCCA bass amplifiers. If you want volume and SQ, check out the Stevens line of midbass and coaxials to foot the bill, For the money the SB acoustics are really, really good.
