THATS BECAUSE YOU HAVE 1 BADASS SUB!! What version is your MAX??? AND HOW MUCH JUICE YOU RUNNING RMS???James330I said:I don't have a ski pass, but the metal plate can't be punched out (its already perforated) and you can take the stock 6 x9 subs out to let more in.
I have had no bass problems so far with my 12" IDMAX in the trunk.
Where on the driver side? Is it aimed to the end of the trunk or forward to the cabin? Have you tried placing it snugged to your ski pass hole?fuschnicken said:Honestly, I haven't noticed any difference in sound quantity/quality with the ski pass removed. I have my sub mounted on the driver side of the trunk.
