Great write-up! I just have a question about your remote wire connection. Does your amplifier only turn on with your engine running?

No, well, kinda.. It turns on with a second push of the start button, so acc power on. If there was a regular turn key it would be the second click....
To put it another way.. when I turn the car off and want to have the amp on without the engine I have to try to start the car without the clutch depressed.

This is the enclosure and woofer of the Premium sound...
It is an approximately 7 ohm woofer: To make sure that I'm measuring this correctly, this is a Pioneer 8" 4 ohms shallow sub for comparison: Thus, a SWS-8 can be installed in a Premium Sound-equipped M3 underseat enclosure exactly the same as in this DIY. In theory, a pair of 4 ohms SWS-8 could be powered by the Premium Sound OEM amp with an inmediate 75% power increase just because of the reduction of the impedance, however the OEM amp not necessarily will be stable at that load. |

Kudos from a Legend
I just installed the Earthquakes with these spacers at Rick Reus' Orange, CA shop. Everything went really well. Rick said I can quote him:
"Tell those guys they did an amazing job making the fabricated spacers and instructions" Means a lot coming from a legend! Take a bow, jtsherri and azwillNJ (BTW Earthquake themselves refer installers to azwillNJ's instructions if they call the company with questions) I have a Reus Systems stereo in my 335 and proudly show it off at SoCal events to help Reus sales efforts. For those of you who don't know him -- the best hidden secret in car audio -- Rick Reus engineers arguably the sweetest sounding high-end systems in the world for BMWs and other high-end cars. He has an amazing reputation stretetching back to the 1970s. PM me for more info. Check out Reus at http://www.reusaudio.com/aboutus.html

I did the install in stages, I installed the subs first then the amp a few days later. With just the subs and no amp there was a significant improvement over stock. And I didn't have any problems. But I only ran like that for like 3 days, so I'm not sure what the long term effects would be.
