After realizing the foam had diminished from my rear deck speakers, I was looking at a $500 investment in replacing them, until..... I found a YouTube video from simply speakers and watched it to see if it were really possible to perform a little d.i.y. intervention and save myself some cash. I ordered 2 sets followed the directions and in less than 4 hours, I replaced all the foam(easily)and had them back in the bmw e38.The dsp system sounds amazing again. Thank simply speakers!
