civic amp/wires/sub install

alright that sounds good... I think I will just have to save a bit and get the JBL amp, sounds like what I need. I still need to install the wires anyway so it will give me time to do so.

I have a new question: my car rattles like a biatch, mostly the doors and kickpanels, so I was thinking I would put this fiberglass insulation behind the speakers in the door- could this be beneficial or will it just get in the way, not help the noises and possibly make a mess on my windows and stuff? I hope it helps, that would be great news... tell me what you think I can do.
