Suggestions Toyota

Hello, I have a Toyota Camry 92 4-Door Sedan. I recently installed a ECD12 head unit which was described as...     *10 watts RMS x 4 channels Power Output into 4ohms     *Signal to noise ratio: 70dBA below reference into 4            ohms     *Dynamic Power: 20 watts @ 4 ohms x4 channels     *Frequency Response: 20 Hz x 20 kHz (-3dB)     *Reference Supply Voltage 14.4VDC     *Single CD player     *Green backlit display     *Audio mute     *Pre-amp output I have factory speakers and as far as I know no amp. I'm hoping you guys can give me suggestions on hardware that would make my car sound better with a minimal budget.My friend suggested that a 50/100 W amp would make my car sound better by itself. Do you think a 50/100W amp would be a noticable difference? As far as speakers, I am just hoping for some input on what would work in my car and any suggestions. I am fairly new to car audio and electronics so please don't flame me if I say something stupid. Thank You.

the ecd12 is an very entry level audiovox radio that im going to guess at you got it on EBAY i guessed that because i googled ECD12 clicked on the EBAY link and the discription was written just like this

*10 watts RMS x 4 channels Power Output into 4ohms

    *Signal to noise ratio: 70dBA below reference into 4            ohms     *Dynamic Power: 20 watts @ 4 ohms x4 channels     *Frequency Response: 20 Hz x 20 kHz (-3dB)     *Reference Supply Voltage 14.4VDC     *Single CD player     *Green backlit display     *Audio mute     *Pre-amp output

minimal budget? plz  let me know what you are willing to spend

what kink of condition the speakers in the car are in now ( do thay all play , do thay sound blown)

because the best thing might just be a better head if all speakere are in good working order if not how much $$$$ u got to spen will help pick out the best speakeres for you money

bring back the rotary phone so i dont have to press 1 to proceed in english

well, actually i'm thinking that i may just buy parts one at a time. I believe it's better to buy good quality items even if it takes more money in the long run. i don't need a full system but i think i'm willing to spend around 200-300 dollars to try to get a medium quality sound system. I won the ECD12 on ebay like you guessed. I noticed it sounds better than my factory head but has primitive features. I think it may be better to upgrade my head system and the speakers, but I need an professionals input Thanks.

sorry for this double post but the speakers are all working well.
