lol sorry I have no idea. If you find out it's 2 ohm, I'll be interested.

Thanks for the tip. I checked everywhere, and it doesn't specify 8x or 8xi. It only says SWS-8.

This is the installation manual that is included with the subs:

For some reason, it says that the SWS-8 is 3.5ohm.

what OEM system do you need to install these do you have to have Logic7 I assume, or do you need an aftermarket amp?

No, this is a replacement for all OEM systems that have subwoofers under the front seats. You don't need an aftermarket amp, but having one will make the overall system sound better.

I believe the silver face means it is 2 ohm...I had 4ohm ones and the face was black. However my box looked nothing like that.

No brackets needed - these fit in the factory locations under the front seats. And you can install without an amp for a small boost in performance. However, it won't be night/day difference unless you install them with an amp. Let me know!

I have 2009 323i which has base sound system. Our OEM HU powers the speakers therefore the power is far too low. IMO if you don't have amp you will reduce the existing bass in your system. These magnets are very heavy therefore to create same induction it would require more power. Moral of the story you will definitely need amplifier if you are adding powerful subs.

If my amp can do 4ohm at 100 RMS I would've bought this. My JL M6450 needs 2 ohm subs. GLWS.

i have an amp that can power these (if its the 4ohm model) with 200w each
it's a kicker ZX400.1 class D monoblock
it can put out 400w into 2ohm or 200w into 4ohm
asking $100 shipped

Stick with JL Audio such as a6450, g6600, m6450 or XD600/6 reasons:
accepts speaker level input
no remote needed
balanced differential inputs
can be over powered
quality

I recommended 6 channel JL amp since you will need to upgrade your front speakers sooner or later. I got mine on ebay for like $250 USD shipped. XD600/6 is new 2010 model, very small hence will fit in your trunk compartment where bluetooth module is stored. You can however invest more on high end amps such as Zapco.

RevC · 05-04-2010, 07:41 PM

run a jl amp to these subs and they will rock! these will run like crap with the stock HU, no other amps come close, sorry.

dgrott328 · 05-05-2010, 12:35 AM

Still available??

AKbmw · 05-05-2010, 12:37 AM

so with a JL amp and these SWS with stock speakers i wonder if its worth dropping like 500$?

since my problem is that the stock speakers dont get LOUD its not the bass or the quality it just dosnt get loud enough . when windows are open i cant even hear my music. i am comming from a logic 7 to a non logic 7 so it hurts.

rockd · 05-05-2010, 12:49 AM

still available...

AKbmw · 05-08-2010, 04:59 AM

just wondering how much did you pay for these brand new?
