hi,
i have a pioneer P7400mp for about a year now,
and its time to get rid of my 2 silly speakers in the front doors of my
car
i prepared some things below here that came up in my mind, even if you can
provide me
an answer to just one thing i would already be greatfull for that.
A weblink to some info i could use is also well appreciated(maybe a forum?)

thank you
===

1 its not because i own a pioneer car radio i have to buy pioneer speakers?
right?
do you have names of other brands ? (prices - quality ?)
what exactly d othose names mean : 2 way/3way/4 way (others...,
difference,price ,....)

2 i own a Toyota, one the site of pioneer i was able to find some info
what kind of speakers would fit however...
the 2 back doors do not have anything provided for speakers, so ... i
wont be able to use a 2nd set of speakers ?

3 in the back of the car, above the luggage, there is a light,
simple(cardboard) covering plate :
putting 2 speakers on it will not very effective due to the
vibrations ?

4 what kind of speakers can i use ?
my carradio : max power out = 50W x 4 , for subwoofer (70Wx1ch/2 Ohm) =
25W x 4
cont. power out = 27W x 4
- speakers for example pioneer TS-G1746 = 2 way tsg series, nominal
input= 35W, max power=160 W,
freq 35-25000Hz,sensitivity 92dB
what is important to know when matching a radio to speakers?
i currently do not have an amplifier

5 switching to another mp3 track (vbr) takes 8 sec. , anyone else with same
type op mp3s having similar behaviour ?

6 whatever you think i have forgotten....
