8-inch door speakers Options

[pepsiman]

I was thinking about putting some 8-inch subs in my doors but i just read that it will rattle the doors real bad...what can i do to prevent this? I have never opened up the guts of my door can u put plenty of sound deading in there? Will that stop the rattles? Also does the subs in the door have to be shallow mount to fit? What is a good 8 inch sub? pionneer has no 8's on their site but primeir does but they are alittle pricey for me i dont need anything crazy just wantin to add some bass but it dont have to be crazy

Ive got 8 inch kicker subs in my doors (RMB8's) ... The reason why i put them is is because they're more secure than a sub in the boot and im probably overly paranoid about getting broken into (aparantly bristol is the car crime capital of the UK!)!

Yes they did rattle a hell of a lot before i deadened the doors. Theyre infinatly better now (especially when the doors warm up! as its about -3 degrees here at the mo!)

Either way there are a few pointers that i can give you:

1- buy "free air" subs - these are designed not to be in enclosed spaces (so are for places like doors).

2- one of the main problems with subs is that there are no mid range frequencies... this means you need to get some awesome 6.5" rear speakers as well as some decent tweeters to cover the midrange.

3- amp them. They sound useless without as you need lots of watts to power 8"s generally

4- sound deaden. Ive used fairly cheap ivanhoe stuff but it makes such a difference. Also make sure its thougherly warm and clean before you attach it otherwise it wont stick and will fall off. Make sure you use as much as you can!

Hope this helps
