will they sound like crap if i plug them into the factory wires

 

The speakers are only going to sound as good as the signal they are reciving. The stock speaker wires are good up to 40 watts. But I seen systems that used 50 rms watts thru factory wires that sounded great. And you would not even tell the diffrence. But thats were I draw my line and replace to bigger speaker wire. The adapters will be okay.

 

my car is old and they have 15w speakers in them can they still handle 40w

 

Yes the speaker wires can, the 15W speakers can also, just not for very long. 94

 

i have some 180 watt pioneers, and my head unit only puts out 52x4, will they still sound good or do i really need an amp.

 

thats peak power. Whats the rms? and model numbers?

this is what i got

 

You have 35W speakers... http://www.pioneerelectronics.....html

Now, what HU do you have? 94

this is my headunit

 

you will be fine with that headunit.

 

ok thanks for the help

 

Ditto the above^^^

Your HU is 22W per ch into 4 ohms...
Audio
Continuous power output is 22 W per channel minimum
into 4 ohms, both channels driven 50 to 15 000 Hz with
no more than 5% THD.
Maximum power output ....... 50 W × 4
Load impedance ...................... 4 W (4 W to 8 W allowable) W should be ohms
Preout max output level/output impedance
.................................................. ... 2.2 V/1 kW 94

 

to get the most out of these speakers will i need a small amp.
