Blowthru for a 2005 Acura TL

[biggermrbrutev15]

I have a 2005 acura TL with sundown SA 12v3 right now in a standard L port box tuned at 32.

Was looking to rebuild the system. 4th order blowthru maybe? The backseats DONT fold down but do have a "passthru" in the middle seat thats about 7 inches wide / 10 tall. Anyway, suggestions on subs? Not hating on any company. I just know that some subs do better in sealed / ported. I would be doing (1)! 12. Would be on around 3000 watts or so (2 strapped hifonics BRZ1700.1s)

Wire - all sky high car audio

Batteries- At the moment my 1700.1 (1) is running off my front battery (optima yellow top). Full tilt, doesn't go below 12.5. WIll be getting an XS Power D4700 eventually. \

Thanks

[Enjoy]

Tuned in have the same car lol
