Ideas of factory looking subwoofer for E46 M3 Convertible

[Tbonem3]

How low do they play?

Takes a little effort, but enlarging the factory holes, mounting some baffles, and dropping a couple freeair/IB 8" subs provides great bottom end with no loss in trunk space (compared to the factory HK sub)

Silly wabbit…

Just need a glitter canon to complete the vibe.

+ you can keep it musical as opposed to boomy… jazz club not strip club, sort of thing… or check that, jazz club AND strip club… acoustically, that is.

Even a little 8" I had in IB in the ski pass moved quite a lot of air (hpf'd @ 40hz).

IB mounting is superior to an enclosed/ported box imo for our cars where we do care about weight as well. And you can get away with an 8" or 10", you don't *need* a 12".

this is what i did in mine and it sounds good…

No, that sounds great. That’s what the BavSound setup was like, and it’s tremendous. What amps are you running? Did you change the head unit to get a subwoofer control? Is that an open air woofer?

I recommend Dynavin (and Jeff Bechtel) without reservation. Opinions on this are all over the map, depending upon your CarPlay preferences. I just needed it to sound great, not look or feel obnoxious, and not waste my time chasing service over BS issues that quality control should have caught before product release. YMMV.

Had no idea Dynavin upgraded their unit to include carplay functionality now. Thanks for the tip!

No worries, glad to help. BTDT. Too bad BavSound no longer makes that ski pass sub, but I'm glad I downloaded and preserved the stuff. The woofer wasn't all that great, but it's workable. There are better slim mount 10" subs out there today, obviously, and better ways to build boxes. CAD processes, materials, amps, all cheaper, better and easier these days. I went the same way as you with OEM look. I recommend Dynavin (and Jeff Bechtel) without reservation. Opinions on this are all over the map, depending upon your CarPlay preferences.

Appreciate everything you have told me, this was extremely helpful. I'll definitely check them out just slowly getting my interior seeming a bit more modern, thanks again!

^^^This is a coupe, correct?

OP, unless you're taking your convertible skiing or something (mine came with heated seats, so maybe?), you'll never have to remove the BavSound SkiPass solution. You simply give up that functionality. But your golf clubs will still fit across the back just fine, two sets even.

Yes, its a coupe. I have a friend that cut out a piece of MDF and mounted a 10-inch sub to where the OE sub normally sits in his vert.

I used a gen 1 Basslink and mounted it to the battery tray. All the connections are quick disconnect and takes 30 seconds to remove the whole subwoofer.

Oh sweet appreciate everything, just something very new to me with audio, also planning on doing a upgrade for my head unit as well, maybe Avin Avant headunit to keep a OEM look but modern features. Would you suggest a different brand? Thank You!

See post #74 and attachments for ideas. I would probably consider replicating the BavSound setup if I had to do it today, except with a 5 way amp to power both the cabin and the sub. The links in the attachments still work to guide you through.
