Sounds like voltage issues? Assuming it is, sounds like you have plenty of reserve capacity (batteries) so you should look into another alternator. That’s a lot of current draw. Capacitors are merely useless especially with your setup by the way so please don’t waste your money on one. The way I thought about it and learned was let’s say you have 1 battery total, that battery will be taking 100% of the current pull your amp wants. Then you have 2 batteries, well, now each battery will basically only drain half of what one would giving you slightly higher voltage. Then on and on. I’d recommend another alternator for your case. I’m assuming you have some way to monitor your live voltage so to kinda troubleshoot, see what your voltage drops to at idle when bumping then go for a drive and see what it’s at because your alternator will then be at max output. If it’s noticeably better on the drive then bingo, need another alt. But if you’re looking to have the car turned off at these shows, I guess just buy all the xs power batteries you can find man!😂

So, I’m looking to upgrade to 2 XFL 12s here shortly. Losing my mind trying to find/come up with a proper box design. I have some room to play with as I’m in a 2002 ford explorer. Only big preferences are that the box is 16 inches tall to stay flush with the back seats, 32hz tuning, aerport(s) box, and subs facing up with the port(s) facing the back/hatch. Currently thinking 5 cubic feet would be best as AB states 2-2.5. Would love some insight on aeroports as well. Placement? How far from the back of the box? How far from the subs? What kind of area would I be looking for? 4”, 6”, 8”, multiple aeroports? Do I need internal pieces to direct the airflow to the ports? Can’t find much online on the displacement of these woofers either. Appreciate anyone willing to help out!

I’m new here so hello👋 Gonna give you guys some background and details to work with. Just have a few questions and looking for some insight. -Current setup- Kenwood DDX73BH HU Cheap pioneer 6x8 mids from Walmart running off the HU *cringe* DB Drive WDX 12G2.4 2.6 cu ft box (net) tuned 33hz Taramps HD3000 @2 ohms currently Stock 130A alt 95ah AGM second back battery 1/0 OFC power & ground (grounded to the frame) Voltage is hanging in there sorta, already planning on and most definitely going to be needing a HO alt which is in the works. Second battery is helping me stay alive in the mid 12s voltage for now. Thinking of getting 2 American Bass XFL1244s and a Taramps Smart 5 as well as building a custom box. 4 channel amp and some proper components are coming in the midst of all of this but that’s easy stuff. -My questions- Amp has dual + and - inputs, going to run another line of 1/0 + to the back battery then to the amp. Will be pulling roughly 550A of current with the Smart 5. Do the double power runs split the load or will it just more efficiently deliver the power? And do I run 300A fuses on each power wire or will I need to run 600A fuses on each? Are the American Bass XFLs a good buy and/or are there better out there for the same price or similar? Is the Smart 5 a good buy and/or is there better out there for the same price that is recommended? Ik I will be technically overpowering the XFLs, but that’s my goal, will have gain set with the DD-1 so I’ll be at a very good power level without wanting to or even getting close to clipping. Will the second battery and a 320A alt be sufficient? Where should I run my second ground to? Seat bolt? Stay on the frame? And if I stay on the frame, how far apart do they need to be? Second battery is also grounded to the frame. DISCLAIMER: setup is NOT pretty, I’m in the works of trial and error, as well as getting my system where I want it so it’s a lot easier to take stuff out. But, here are some vids/pics of what I’m running as of now if anyone was curious as well as the WAL dyno sheet for the amp I’m looking into. IMG_1247.mov
