Upgrade factory speakers

elerner61 · 02-11-2012, 06:45 AM

Took one of the subs out yesterday and did some measurements. Stock opening is about 5-3/4", depth of the stock sub is about 3-1/2 inches. However, the stock sub has a surface flange that extends out the front to meet with some plastic lattice work on the back of the stock grille.

I just ordered a JL 6w3v34 and I'm going to see if I can "make" it fit. I'll have to mount it on a ring to get the back clearance in the enclosure and then trim some of that plastic from the stock grille.

Let me know when you're going to start doing this. I'm going to either rip things apart and STOP the bass-rattles, or replace my drivers. I tend to run Dynaudio and Vifa components in my cars which improves the sound/imaging IMMENSELY.

For a THX-certified system with Carver drivers... you'd THINK that it'd sound better than this. Those are/were big names in the industry.

Anyhow... keep me in the loop on this. Maybe someone can comment if they've undertaken any audio upgrades/tweaks?

Well, Dynaudio and Vifa have ALWAYS been better than Carver. Two of the premier brands in DIY speaker building for at least 20 years.

Page 3 has most of the results. My friend and I met to do some coding in my car, and compared stereos, both 2007 M models with Nav, only difference is roadster versus coupe, he was blown away by how my system sounded versus his. I really think that "Working with Carver Subs" thread is onto something.

Great info! I've been reading for a while now about how bad the bass is and have been really wondering if my ears are that bad! I have a 2006 M roadster. All DSP is off and I only have a tiny bit of boost at 80 Hz and mine sounds really good with good source material.

I was really confused with these comments as I use top line Shure earphones with lossless music in my iPhone when on the road. At home I listen through Klipsch laScalas with high end electronics. At this, the bass in the M ain't perfect but it ain't bad either.
