Decent SQ system?

Hey everyone, I was wondering what would be a decent system to put in my truck.  I have space for 4" up front in the dash, 6"x9" in the mid pannels, and I was gonna make a custom box to hold a sub behind the rear wheel well.  What I'm looking for is a setup that will give me relatively lound volume and low response without distorting at a reasonable price.  I'd like to keep it below 1k becuase I have heard it done for that, and that is approaching the cost of the vehicle .

For a sub I was thinking an Infinity Perfect 10" because of the low response I've heard about.  I'm not sure what size would be good but I think with around 250 watts one will be able to fill the whole cabin.  What else from JL, infinity or any other company would be a good choice here?  And an amp to push it?

For the 4" I was looking at component sets but I don't know whats good.  They will be getting 26 watts from the deck unless I need maybe a 4ch amp or something.  Would 2-way 6x9s fill it out good for the back seat?

Thanks for all the info,

Matt

FYI if you didn't know that kappa runs $109 i think for the 10" on http://www.crutchfield.com.  One of them will do.  And $200 for some good front speakers?  wow.  I was thinking maybe $150 (max) for a pair of good 6.5".  If I was you I would amplify all your components and have a seperate small 200-250ish watt amp to power the sub.  The amplfied signal will clean up the component signal a little and give it more "loudness".  And to go with a bigger speaker up front....one word:  fiberglass.

Just my $.02

Wow, I didn't expect so many responses so soon, thanks everyone.  I already have the head unit comming in the mail (birthday gift)  so I only need the rest of the system at this point.  As far as stock speakers go this beast is not in good shape...the 4" in the dash ARE the only speakers so I figured I'd at least get some decent rear speakers, but if you all think that I could go cheap there and splurge somewhere else then I will deeply consider that. 

I think I'm gonna do some scratch and dent shopping on crutchfield so even the Infinity Kappa Perfect 12 VQ (are they really worth it) would still come in under $150 and I'm sure I could find a decent sub amp for around the same price.  I'm not sure how I should go about upgrading to 6.5" in the front, any ideas for speaker pods in S-10s?

And on the amp topic I was planning on doing a mono sub amp and buying a 4ch for the rest of the system in the near future.  Or would it be better to just get one 4ch for now and bridge 2 for the sub.  It says the Blaupunkt pushes 26 watts rms so is it really that big of a step to an amp?

Thanks for your thoughts and info,

First, I'm glad you're getting a Blaupunkt - they are great quality for the money.  Second, yes, an amp will be a huge step up.  It will be a huge step not just in terms of available power, but the power it does put out will be more free of noise and distortion. 

Either glass the kick panels yourself or these Q-Forms work for your Blazer:  http://www.crutchfield.com/S-vgZ2rWIdPJa/cgi-bin/ProdView.asp?g=182850&I=044K100313

You don't need to spend any money on rear speakers unless your current ones are blown.  You should barely hear rear speakers in a quality setup.  As you said, splurge on the front - you won't be sorry.

I would not run a pair of components on head unit power.  A pair of quality 6.5" components on a good amp + a quality subwoofer will go a long way toward getting you great sound.  Having these things in place is #1.  Quality installation is #2.  Finding some rear-fill w/ 6x9s or whatever should be your last priority imo.  Splurge on the front.

Sorry I havn't replied, I have been working and installing the H/U!  Unfortunately, the guy before me twist/taped the connections after CUTTING OFF the wiring harness so I'm sure you know how much fun it was taking off all the connctions I already soldered and rediong it to the harness in the car...

All I can say is WOW what a difference between an 80's tape player and this new cd/mp3 player (like that was unexpected).  Seriously though it cut almost all the distortion and I can drive the speakers much harder but they are so bad it hurts to listen.  Since I don't have rear speakers I'm thiking that a mid range 6x9 2 way, or maybe even a 6.5 w/ tweeter could actually do the most to help the overall sound quality.  I mean if I'm just gonna fill it out with one of them later why not do it now and take away the horrible imaging of only having front speakers?  Give me some recomendations.

By the way I do have some pics of the install which I will put up as soon as I get the damn cable from my friend.  The kit from crutchfield looks a little goofy and doesn't exactly fit. so I am planning on fixing this when I install my next component.  Also, those butane soldering irons are great except the tip for mine wouldn't heat the wire enough so I just use the flame ,now it works even better.
