Hi all! I recently purchased a 2004 100 Series and I love it. I've been sorting out things like check engine lights and rust, so I decided to take some time for a luxury item as well. My sound system is blown. If there is any bass in a song, it sounds like someone is rattling a box of fishing weights near the subwoofer and passenger side dash. I assume music was just played too loud too long. Since it is only a sound system, I'm not looking to pour an absurd amount of money into speakers, but also I like my music. Any advice on where to get replacement speakers, OE, or aftermarket would be appreciated. Also, I have no idea how to access the speakers, so advice there is definitely needed. I think I'm going to need to get to the front door speakers, definitely the sub in the rear, and if there's anything in the dash itself, that too. Thanks!
