My factory bose system in my 05 CTS-V carries a 2 ohm load at the doors...I am trying to replace my speakers while retaining the factory amps. Should I try to find a good replacement 2 ohm 6.5 and 5.25 coax or will running a 4 ohm speaker suffice? Any suggestions on speakers? I was looking at the Diamond 661i's but they only seem to be in 4 ohm along with all the high end coax/component sets. Please help, I would like to make this purchase within the next week.
