Hey. I just picked up 3 12'' subs. Theyre all HFI12D4's. 300RMS/ 600MAX Each. Dual 4OHM.

I plan on using these with my 2000 watt amp. Its PLA2378 Maximum Power Output 2 x 1000W ***Bridgeable RMS Power @ 4 Ohms: 1x2000W ***2 Channel Bridgeable MOSFET Amplifier

im not too familiar with bridging and stuff. What would be my best option in wiring these to get the best sound quality and most bass?

Also this is going into an 83 Cutlass. I have a H/O Alternator. New battery. What gauge wire should I go with and what all would I need? Thanks

Your only safe option is 6ohm. You would be better off using just 2.

but here is how to wire all three. https://www.the12volt.com/caraudio/woofer_configurations.asp?Q=3&I=42#results option 2

Doing just 2 you could do a 4ohm load. Getting full power from the amp.

That amp will last you longer running 6 ohm. If you insist on running it at 4 ohms, you will need 4 dual 2 ohm drivers

With 4 subs he could wire each sub in series (8 ohm for each sub individually), then pair them up in parallel to get 4 ohms. Run each channel on the amp to 2 subs.
