Now that I have the car I plan on keeping for a while, it's time for some BASS. I guess I have the monsoon system with the 8" woofer. My question is how deep is the stock enclosure and about how much air space does it have. I think TS upgraded his to a 10" and I think that's what I'm leaning toward. I've looked up several shallow mount 10in subs and hopefully there's enough room to get it in there and still be able to get the waterfall back on without the speaker surround hitting it. as far as the amp goes, I'll probably keep the stock amp and use a new amp for just the sub. then I can turn the bass down and save the stock set-up. any ideas, been there / done that's?
