The higher end NVX subs look great, but I'm worried about the power draw. Not only does it put me over budget but I don't wanna murder my alternator. lol
Power draw is an efficiency metric, RMS is the thermal limit. The wire harness is around$40, the power kit you'll need to go with is at least a 1/0 around $100. You need a breaker for the under the hood and a dual fused distro (Future 4 channel), another $60 for the two. That leaves around $600 for a good box and a couple of 12's. For an LOC, get a good one, like this

The guy will sell them for $50 (offered to me previously) and it will facilitate the addition of a 4 channel amp down the line. Not going to get into DSP, whole notha ball game and serious amount of time and added cost - now @ $550 to work with.
Fi are very nice, just a bit over budget. Let’s shoot for a 2 ohm load to keep things cool and stable, not overworked. These are dual 2 ohm, wired in series at the woofer then parallel to the amp, two ohm load. He's asking $145 each but the guy wheels and deals, offer $125 each, he'll probably come back with 130 each so lets figure on $260 for the two.
Electrical Resistance of Voice Coil (Re). Electrical Q Value (Qes). Total Speaker Q Value (Qts). 42.90 liters. Equivalent Compliance (Vas). Free-Air Resonance (Fs). Shallow Mount Installation. Top-Mount Depth (Mounting Depth).
Down to $290 and cutting it closes. Those subs will handle 1200 watts RMS, so they need a decent box

Keep in mind, that I have included the LOC, the wiring and fuse/distribution blocks so technically8, still right on target.
Amplifier. While Korean higher end builds are known for their headroom and build quality (used to be staunch advocate), new full bridge offerings more than make up for this with the output. I think a decent 2000 watt 1 ohm stable amp is what we should be looking at. The smart versions are great, have regulated power supplies and have gobs of spare power.
This guy wants $250 plus shipping, offer him $250.00 shipped.

2000 watt option - Taramps Make a reasonable 2000 watt amp, but it's not a Smart unit and that is a significant difference so I don't go that route with their line. These are nice and they come in three colors!

You could shave another $40 dollars off that and go with one of the new stinger amps which are a stinger design and have gotten pretty decent reviews. This one at $160 is rated at 1500 x 1, at 2, about 1000 watts (nothing to sneeze at).

That $60 XS power battery upgrade for the back is something I would also consider in lieu of an electrical upgrade. You going to get people here that will insist you need a big electrical upgrade, but really, I design builds with an eye towards overly strong output capability so that when you never use half of it, it last a long time. Here is an example of what I’m referring regarding actual output versus assumptions on what you will u se.
This is a fine staring setup to get you where you need to be going into phase two and as expected, got some ideas for that too – including a good amount of sound deadening you’ll want to put down. At the very least, everywhere you mount the speakers.
At $400 for the 4 channel amp, leaves tons of options available and probably less - BUT if you want to go crazy… I’m currently selling one of these on here for $375, you can have it for $350 shipped if it’s still available.

A used 7 out of 10 condition Focal FDP-600.4, $350 shipped- the new one is listed on the link but I have another one, used.
That SFB is a crazy amount of power and you'll likely need a 2nd battery at around $400, something to consider. I've got some good suggestions on the speaker option too, when you decide on an amp, and the ones I have are 150 x 4 and 350 x 4 and not inexpensive, they are however very nice amplifiers. There really is a lot of options there when you get ready to do that. My initial suggestions for the sub amp and subwoofers is predicated on the scenario for finishing your build in a manner that won't disappoint. If you're really ready to do it right, in three stages, you can end up with a sub-stantial setup, no pun intended.
