Need help on adding a 3rd Sub

MP2121 · Oct 30, 2022

Hello everyone, I'm new here, and I'm fairly new to wiring/installing systems, although I've had em in my cars over the years quite a bit. Currently, I have (2) JL Audio 12W0v3-4's in a ported box, with a JL Audio JD 500/1 then a JBL Stadium 4, 1500 watt(100x4 rms), to power my factory head unit/DSP, my components up front, 6x9's in rear shelf... I'm wanting to add a 3rd sub(same as other 2), and I'd upgrade my amp to the JL Audio JD 1000/1. If I wired them using jumper wires like my 2 ate presently wired tup, would all 3 subs get 600 watts RMS?? Also my alternator is 130 amps, so would I need a high output alternator as well?? Thanks in advance y'all!

Won't really work. You can wire the subs to 1.33ohms, 12 ohms or 6 ohms. You need a 1 ohm stable amp. Or get some 4 ohm DVC subs which could be wired to 2.66ohms.
