Stereo & Electronics - Considering replacing monsoon..

I currently have a 2001 Camaro SS, with the stock monsoon system. The door speakers are both blown, and i'm considering replacing the speakers, and adding a sub. I'm looking at possible options.

I am thinking about getting a 10" stealth enclosure from subthump, but i'd like to know what sub to get with it

I also need to know what kind of speakers to get, as well as an amp.

Also, is it possible to use the stock monsoon HU as a radio/cd player (and also because it already works with the steering wheel controls).. but pass the signal off to the amp and run the speakers off of that, for a nice stock look, with improved sound? Or is the stock HU really bad quality wise?

I am very into sound quality, and not so much pure power. As long as I can hear the music clearly with the t-tops off, I'm good.

I'm also wondering about rear fill.. I think I would like some speakers in the rear, even though it's recommended against.. if I wanted them, what should I get, and should I put them in the hatch or in the sails?

I'm also wondering how much this would run me. I'm looking for affordable quality. Thanks.

Yes you may keep the stock HU if you wish....but as you thought, it is the worst component as far as quality in the stock system, as it puts out a lot of distortion.

As far as sub/amp selections, etc.....how much are you willing to spend?

I don't really have a budget, and I don't know the usual prices for car audio. Looking for someone to put together a system that should fit my needs. I can save however much I need, but I am really looking to see what I can get, and what it'll cost. I know the rest of my monsoon probably won't last much longer, so I'm looking for alternatives to just replacing bad speakers.

If the HU is really that bad, recommend a replacement. I'm into a clean-look, preferrably with a volume knob rather than buttons, blue lighting, and easy to make work with the steering wheel controls

I listen to electronic music.. such as Drum'n'bass, trance, breakbeat.. I occasionally listen to rock, metal, very rarely rap, etc.

Alpine has some nice HU's. That is the way I'll go in the next month or so.
