I recently got my first car: a 2000 volksvagen beetle but have been driving it for years.  I have never been impressed with the car speakers so I want to upgrade them but not substantially because I do not want to invest too much in this car and I do not need 'loud' blasting music.  I just want something crisp and clear.  Although I had not considered getting a reciever at first I did decided to settle on getting one: the http://www.crutchfield.com/p_130P6000UB/Pioneer-DEH-P6000UB.html?tp=5684&tab=features_and_specs (pioneer deh-6000ub), particularly because of its ipod connectivity and cd (also good looks!). 

I have submitted my car as my vehicle on outfit my car and it tells me that I have Rear Seat Side Panels: 6-3/4" but Front Door: 6-1/2" speaker sizes.  Also I have a "factory speaker not" on my front speakers that says that no speakers match my size exactly.  That being said, I have come to like the Alpine sps-600 type-s 6-3/4" 2-way speakers (http://www.crutchfield.com/p_500SPS600/Alpine-SPS-600.html?tp=105&tab=features_and_specs).  Under the product image, it says that these speakers fit in my rear seat side panels.  Although the title of the product states that it is a 6-3/4" speaker, the small description under its title states that it does fit in 6-1/2" openings. 

I have multiple questions regarding my soon-to-be endeavor into car audio:

Can I purchase two pairs of these speakers to outfit my car's four openings, particularly will the pair of speakers fit in my front openings?

If I get this reciever and the four speakers will I need to get an amp for them to work? (like I mentioned, I am not looking to blast music or have my car audio heard 100 yards away, I just want it to sound good).  Also what would the consequences be if i do not get an amp?

Please I am open for suggestions.  If you feel I can use any other products that would make my situation work out for the best please let me know. Thank You

Looks like you also have stock tweeters in the dash.

Here is a better choice to be powered by your headunit. They will play louder with less power because they are only rated 2-ohm resistance/impedance. They fit front and rear. I would just disconnect the stock tweeters. For the best results, use 150 hz bass blockers and foam speaker baffles. You will be happy you did.

Those Alpines don't look like they will fit your front doors. Probably too deep. Also, they would be better powered by an outboard amp. In most cases, however, if you want an amp, look for speakers with an RMS power rating beginning with the number 5 - ...  There is no consequence of not using an amp and higher-end speakers.

Hope this helps. Good luck.

Thanks for your insight.  I had read another post before I posted this one where a person had at first liked alpine speakers similar to mine but was suggested to get these infiinity speakers.  It would make more sense if they are more sensititive and I am not using an amp (Im just guessing).  I also like that the infiinity speakers will fit in both my front door and rear speaker openings.

Thanks for replying, GLH :)

After just checking out the reviews for the baffles I was turned away by how they manage to change the sound making it sound worse.  I dont believe I need any protection for my speakers truthfully so I doubt I will be getting the baffles.  But I will definitely be getting the bass blockers.  Thanks for letting me know about them!

If anyone us has any knowledge I can use or any opinions on the answers to my original questions, feel free to respond.

Instead of bass blockes and baffles get some Dynamat to use on the door panels when you mount your speakers. I believe your Pioneer has onboard xovers to fine tune the bass going to your speakers. The Infinity components are a good choice, but you would not go wrong with the Alpine type S, or Polks db series.

RBL is right about the crossover built into the headunit. Bass blockers are for systems without crossovers built in such as stock headunits.

I never thought much about the baffles myself until I actually installed them on all 4 door speakers and heard it for myself. They help the sound of the speakers much the same way sub boxes help the subs. Also, they lessen vibration, resonance, and distortion,  helping the speakers play louder and clearer.

 No full range speaker will perform to it's potential if it is trying to produce low bass. When the specs say 40 - 20000 hz, regard it as meaning it will reproduce 40 hz or 50 or 60 or 80, it don't mean the speaker will sound good while reproducing it. Subs are for frequencies below 100 hz.

Yeah the lower end of the frequency spec is only if the speaker is mounted in a box so it is basicaly useless.

I've heard mixed reviews on the baffles as well - no harm in installing the speakers without them first and seeing what you think.

Same thing on the 150 Hz crossovers - I don't know that I would do that without a subwoofer in the system - but you can enable and disable them in the Pioneer deck and see what sounds best to you!!!!

Hope This Helps!!!
