Hello,

I'm selling my pair of 8" shallow subwoofers specifically for newish BMWs with the 8" underseat location (top hifi/logic7).

I'm using a 10" enclosed sub in the trunk for my bass now and would rather recoup my money on these.

These are a fantastic upgrade especially if you don't want to get into any extra custom audio work. Plug and play.

Match 8b-BMW.1

Tthese retail for about $500-600 and are often $300-400 on ebay etc.

They're in great condition, nothing to report on.

Asking $240 paypal/venmo/zelle

Local pick up in socal 91360 - I can ship as well

Hey Tyler, how do these play with the matchup7? It puts out 160w at 2ohms but I see these are rated 4ohms.
Hi Mike so if 4ohm is presented, you'd halve the power draw (80w). I think these are rated 100w rms, so 80 is pretty close. I believe they did make these in 2ohm, but any of these european 8" shallow woofers are hard to find and expensive :(

Any idea how these compare to BavSound subwoofers? I don’t see a factory style connector, how do you install them ?
Very comparable to bavauto. These are like typical aftermarket speakers, so you'd strip the ends of the wire. I saved my plug ends and can splice (butt crimp) them back.

These would be a great upgrade for cars with Individual Audio which has great clarity but lacks bass. GLWS!

Hello are these available, located in socal as well.
Do you have the logic7? I think that's what I have. I fair as well as any other DIY'er with electrical work but would love to hear more about the install. Lack of bass is my biggest concern with my audio. I have the "2011.5" M3 sedan. I'm located in Seattle but my father in law is in Encino and he will visit us soon so I can work out both a shipping and pick up deal.
Yes, these are available. I'm in 91360. I don't have logic 7. You'd want to match impedence. These might work. Some are 2 ohm, some 4 or 8. These are 4 which is very common in car audio.
Hey I pmed you about the subs
