and the speakers are 2 ohm

2 ohm speakers will make your headunit shut off at high volume, and sound distorted at low volume. Don't do it.

Audio
Maximum power output ....... 50 W × 4
50 W × 2/4 ohm + 70 W × 1/2
ohm (for subwoofer)

Continuous power output ... 22 W × 4 (50 Hz to 15 000
Hz, 5% THD, 4 ohm load, both
channels driven)

Load impedance ...................... 4 ohm to 8 ohm × 4
4 ohm to 8 ohm × 2 + 2 ohm × 1

thats the info it gives me

you can get away with 3 ohm. but 2. no unless you have a 2 ohm stable amp..

those are the numbers for the head unit and the speaker will be wired right to it

the cooling in most head units isn't capable of dealing with the extra heat created by running at 2 ohms. Just get 4 ohm speakers.
