Gents,

I have a pair of Earthquake SWS subs with adaptor rings in great condition I purchased them from a member who had them in his car for a week and decided on a different set up. I also decided to go with a trunk sub instead and never installed. Looking for what I paid. $190 plus shipping. Pm me if your interested.

Thx

I was planning on installing them on an F82 M4 but they fit under the E90, E92, F30, F32, F80, F82 seats. Basically hey will fit under and are a popular upgrade for the under seat stock subs in the 335, 435 and M3/M4. You will need to push these with an aftermarket amp and harnesses depending on your stereo options are available from Technicpnp.com.

I bought from Romanonj see his thread below this thread he was selling the entire set plus BavSound speakers and am for $1100 as it shows pics of the subs. As mentioned I am going with a trunk sub from MusicarNW for my M4.

Do you have pictures? Do you think it matters that I have a 328i f30?

They will fit but will depend on what type of sound you have in the F30, Do you have HK sound or the HIFI or Stereo? There is a thread on getting the stock subs out of the stereo boxes that requires a hairdryer or heat gun etc. check out the electronics section of the forum.

I have the hifi sound system. Will these work with the hifi or are they for the HK? What's the part # of these subs? If you don't mind. I just want to look up the specs first.

Model # is SWS-8xi so they are a 2ohm version that can be wired as 2ohn or in parallel as 4ohm based on your aftermarket amp. A link to a good DIY below and yes they will work with your car.

You will need a harness from technicpnp and a subwoofer amp to power them.

I can't just run these with my stock amp? I thought that since I have the hifi system I'm already running at 2 ohms?

If it's 2ohms you can run with a stock amp. Honestly I have an M4 with HK so I don't have all the particulars on your car. But I'm sure the forum has more info if you look around.
