Has anyone done a "Big 3" electrical upgrade in their V2? I'm about to put a little audio upgrade together in my 13 v coupe. And I have no intentions of upgrading my alternator. I'm gonna be running a 2000 watt RMS amp for my subwoofer. So I'll most likely upgrade my battery to an XS Power agm along with my little add on lithium titanate battery. But it would probably be a good idea to beef up my electrical wiring, assuming it's possible in these cars. I've never done a Big 3 on a car with the battery in the trunk. So that's why I need some help from anyone that has

You could upgrade the grounds from the battery to the chassis and engine to chassis for sure, not sure you'd gain much though. Larger gauge from alt to fuse block, from front fuse block to battery would be the big pain in the cock though. Not sure how guys work around the field turning on and off in the alternator on newer stuff, been out of the audio game a while now. It may react fast enough to make no notable difference.

Yes. One of my concerns is these newer cars have a voltage regulating collar on the alt to fuse block cable that tells the ecu to cut it back when it's giving too much juice. Which when upgrading for car audio more juice is what we want. But the ecu doesn't know that. So I don't think it'll work out the way the older cars that I'm more familiar with would. I might just keep it as is and hope for the best

There is a way to bypass the current loop... And I believe I did it when I LS3 swapped my tbss, however the method evades my mind right now.
Well if you do have a flashback at some point in the near future, throw it on here or inbox me if you can. I'm gonna see how my electrical system holds up with an AGM and my little LTO battery. I have a Supercaps Bank I might throw in there as well. If it's struggling to keep up then I'll try to figure it out. But that's all a month or two away anyways. I gotta get a custom box built for the X12 to fit in the V Coupe trunk. Those swan neck hinges are a bit of a problem for the usable trunk space

[email protected] = 166A. I think you're going to need an upgrade of pretty much everything in the DC power circuit to get it to hit that level of power.

Note also, if that 2000W rating is for the speaker, the actual amperage is going to be closer to 200A since the Amplifier isn't going to be 100% efficient. Figure 85%...

Yeah. I'm not gonna be able max it out for long periods of time. But I'm getting rid of the lead acid battery and replacing it with an XS Power Titan8 S5 and supplementing that with an LTO 6.0 and a Supercaps Bank. So as long as I use it in moderation I should be ok. I'm not trying to do any SPL Drags or anything
