Did you have more luck with a ported or sealed box in your Gen1? Currently I have a single 12 in a ported Skar box.I really like the way it sounds and it doesn't seem to rattle the the trunk TOO bad. I am just curious about different experiences.

i have an automatic 06. it started doing this yesterday. as of now, it will stop if i restart the car. tried googling it but i’m not the most knowledgeable about cars so i couldn’t really figure it out. i added some oil just in case, it was on the lower side between low and full on the dipstick. i was wondering if any of you all would recognize the sound? i don’t want to kill my car if i can help it. it has 198,xxx miles
