I don't know why but my car has 6 speakers.and no deck.
so I am gona put the deck and hook up the speakers.

But I know usually deck has 4 channel but can I hook up all 6speakers
without Amp? How?

I just got the car 3weeks ago without a deck.
It is 93 touring so it has rear bose accustic thing but someone took amp out and bypass it so it has 2-2ohm speakers.

and 4 actually 5 more speakers.

2 -door speakers- infinity but i don't think they have Amp didn't check for OHM

2-rear(above stroge bin) speakers --same as door speakers.

1 center speakers--didn't check if it'functioning.

I have alpine deck it has 4 chanel out and 2 channel pre-out
I want use all (at least 6) speakers .

and I found someone did lots of modification on the wirring he put the
new speaker wires and also some coils and condensor? thing also he was
running big-sub can i just take them out?

I don't spent lots of mony on the radio stuff.
but i want hear music from my all speakers because it's taking space
and weight for nothing...

sorry for the messy post but please some one help me.
my local shop wants 150 bucks for the installation.

You need to get an amp for your sub. Center dash speaker( tweeter) you can connect it parallel with one of your door speaker. It won't sound as good as you have an amp thought.

You need amps to run it right. Under powering speakers is just as bad as over powering them.
