Help building a system, ported into the cabin

[Jayr0071]

hello everyone,

I'm new here and would like to some inputs for a new system I'm trying to build. My previous car was an ml320 with a bose premium sound system and the bass was perfect. Currently my 530i does not have any bass and would like to build a similar bass output, I'm not looking to crazy bass. My last build was over 8yrs ago and with 2 12" subs the whole car rattle, now i'm looking for a more OEM bass.

Before i start building and buying parts, I'd like some inputs and some recommendations. I'd like to go with an 8" or 10" sub facing into the cabin, similar to this:

From what i'm reading it might sound better if its ported...similar to this:

What do you guys think? What setup would be better, sealed box or ported? Is it a good idea to make the sub face the cabin? and what size speaker do you recommend?

it sounds like you would be happy with the sound of just a single 8" or 10" sub in a sealed box. a sealed box would get you better sq than a ported box
