this will be mounted in a custom corner box.
2. Replace under seat subs with SWS 8xi’s
. ( I understand that these are not the best for midbass, and I am okay with that) I will be running these off a JL Audio JX250/1
. I will wire them in parallel.
3. Technic Harness (Already purchased) The “Add a sub” wiring is pretty straight forward, no confusion there. I’m a bit lost as to how to amp the under seat subs from the harness so if you have some insight I would appreciate it (if not im sure I can figure it out once I have everything.)
So if you guys could give me some feedback/suggestions on this. I’d appreciate it. Thanks
The included pig tail (4 12AWG wires) connector is wired to your aftermarket amp outputs -in your particular case, to the JX250-1 amp outputs.
Then you plug that pigtail into the harness -there is only one matching 4-wire connector in the harness. No way to plug it any other way.
