[QUOTE="ladysmanfelpz, post: 8429697, member: 642267"] I think I'm gonna try that abs plastic route. I know people say you need to "seal" your door to get that midbass kick, but you really only need to separate the back wave from the front wave. Plus I only have stock speakers currently so not like I'm gonna be blowing my doors off. Not wanting to drill sheet metal into my doors, I simply just put a layer of dynamat over my access holes on the inner door skin to do the trick. The thing is is I can hear it moving, cracking, and creaking on turns and bumps. Pretty annoying and fairly noticeable. It did decrease my roadnoise, but being flimsy I can't help but think it does a poor job of blocking out those 60-200 hz frequencies. I now know it is necessary to give the CLD something to adhere to. I think the abs plastic will be a safe alternative to sheetmetal and give my door the rigidity and ability to add multiple layers of dynamat to serve its true purpose. [/QUOTE]
