I have a buddy running a 240 amp alt in a small Nissan and he's running 125 amp hours of lithium clamping 7k. I ran a 5k set up in my Maxima with 300ah of AGM and a 270 amp alt @.5 and my voltage would tightrope 12.0-12.2. @7k you're pulling 700+amps. Do the math. You need more reserve.

Equivalent to (4) 100ah AGM batteries" is what they claim You're not running 8500 Watts off of 400ah of AGM batteries. That's just 3 xp3000's and a starter battery... Exactly what I just put in my Lincoln Navigator with a singer 320. I'll be good for about 6k total watching my voltage. I wouldn't dare try to run 8K off of 3 rear batteries and a front battery. Man they'll tell you anything to sell you some s***. Link to comment Share on other sites More sharing options...

I guess what Im most concerned with is the grounds. The lithium battery has 8 spots for (+) and (-). On the positive side that will be 2 spots for charging, 2 for mids + highs, and 4 for the bass amp. I'm unsure of what needs its own ground and what should be grounded to the battery Link to comment Share on other sites More sharing options...

I've still got a lot to learn and I did consider just buying a bunch of agms. Its just the weight that will kill my ride man. I didnt come into this expecting to get 8500w daily. What I'm looking to do is get my two 15's moving, some mids and highs that can keep up, and not have to worry so much about my voltage, on somewhat of a budget. ?

My point is unless you're running some 4-5k Subs... 5k RMS is plenty. Grab that battery combo and be good for about 6k. Link to comment Share on other sites More sharing options...
Twonnie Posted October 30, 2018 Author Report Share Posted October 30, 2018 Soo I still need some advice about my grounds. There's plenty of meat to bite into in my trunk area and I have plenty of wire / lugs on the way. I know in the car audio world there are a lot of things that can go by a simple rule of thumb. From what I've read around it seems for every power wire there should be a ground wire of equal size running to a nice chunk of metal. Please correct me if I'm wrong though Link to comment Share on other sites More sharing options...
Ron36 Posted October 31, 2018 Report Share Posted October 31, 2018 No such thing as to many grounds , I Ran separate grounds to every battery and every amp they are tied together through the body. 2022 Ford Maverick on 22’s Skar SK1500.1 on 4 Skar VD-8’s Mids Sundown Super tweeters, Skar TX 6.5 components on Skar SKM400.4 LC2 for audio control , XS Power D680 XS Series Extra Battery Link to comment Share on other sites More sharing options...

Nice, How many amps, batteries and individual runs do you have attached to the body? Link to comment Share on other sites More sharing options...
Ron36 Posted October 31, 2018 Report Share Posted October 31, 2018 Probably over 10,got 6 batteries , 4 amps plus big 3, some are on body some on frame. 2022 Ford Maverick on 22’s Skar SK1500.1 on 4 Skar VD-8’s Mids Sundown Super tweeters, Skar TX 6.5 components on Skar SKM400.4 LC2 for audio control , XS Power D680 XS Series Extra Battery Link to comment Share on other sites More sharing options...
Dragonsyph Posted November 16, 2018 Report Share Posted November 16, 2018 Make sure you run a big ground wire from alternator casing to battery neg. From what iv been reading it should be the BIG 4 and that should be included. ♦ Sundown NSV4 18" + Sundown SALT-4 Baby ♦ MechMan Elite 370a + XS3100 - XP3000 ♦ SHCA 1/0 OFC(blue) + SMD Fuse Holders(blue) ♦ Pioneer AVH-2440NEX + SHCA Pro RCA Link to comment Share on other sites More sharing options...
