Okay. Im okay with that. Medyo limited kasi ang budget. Pero wala naman bad feedback sa david street sound?

Final set is:

Alpine HU
Domination Seps
Domination Subs
Domination Amp
Audiomax wiring, gauge 4
Sealed enclosure
E46 HU panel
Installation and Tuning

Would that be okay as a minor upgrade to ny sound system na? Thanks!

And how can i do "active" tuning? Thx!
