Correct.

Correct.

Will wiring them at 1 ohm put more stress on my electrical system? (Stock alt and batt )

you should be fine with the stock electrical on the brz1200 on stock electrical.

what size alt do you have by the way? also to help out id just grab a extra battery to go in back by the amp to help out some if you drop voltage to much

I think there is a slight miss communication. I meant 2 Obsidian 12" v3. ( Obsidian Car Audio ) With that being said will the light dim or anything like that? And will a 4 cb ft ported box get the job done?

that would be my bad i thought i read 2 "zv3" 12s lol. my bad

I honestly don't know. 1 last question. If I were to get 2 15 Obsidians what kind of amp would I need and would that one cause any electrical probs? Thanks!

the whole line of obsidian's are rated 600 rms so you could get the same amp and be good

You are pushing it on room for 2 15's man. I would do two 12's in the proper enclosure and call it a day. If you have never had a system this setup will blow you away. You might shoehorn the 15' in there but the box will be so large you will be choking off your output.

Go with the 12s they will perform better than the 15s bc they will be in the right size box ..15s would have to have a box built in the trunk more than likely.as far as amp or electrical..id get a amp that does 1500-1800 rns ..the ppi bk1800 as suggested is a good amp for 199 bucks ...u will need to look at doing the big 3 and replacing the battery under the hood with a agm ...then monitor voltage drop and decide if you need a secondary battery..also make sure u get a custom box designed or built to make them shine ..a prefab box will not do those oa.s any justice

what If I only did the big 3. Would that give me the power I need?

Ur gona run into issues

Anything over 1k and I'd suggest a Big 3 minimum

1500+ would need an AGM + Big 3

and pushing 2k, depending on alt size, you might need an additional battery in trunk
