I wouldn't do the cotton ball thing. Because if the cotton touches both tinsel leads, and then gets wet (because it's in your doors and that can easily happen), it may short the tinsel leads. Bad news.
I think you need high pass your front speakers so they aren't playing such low notes. This will limit their excursion. Now save up for a set of mids with tinsel leads woven into the spider...although I don't know if they make many of those...so just get a set of mids with more excursion. What are those?
