My buddy has a 97 trans am with the 8 speaker system. I remember hearing that some of the newer trans am's had 2 ohm speakers. The rear 6 1/2 is blown, so can i replace with a 4 ohm aftermarket speaker?

 

You won't be able to. I'm sure somebody can explaing better than I could.

 

if he has the Bose system, then yeah, they are 2ohms. You can replace it w/ a 4ohm speaker but it just won't be as loud

 

Do you know of any aftermarket companys that make a 2 ohm speaker, or is he stuck using a 4 ohm and getting crappy sound quality. Do you have any idea of how much a 2 ohm speaker would cost from a dealer?

 

It's going to sound like crap. Trust me! I replaced my middle set of speakers after they were blown with some set of Pioneers and they sounded like crap.

It's best to go back to stock or change your whole system completely.

 

 

if you have a 4 ohm tweeter and a 4 ohm 6,5" you can connect them paralell and the circuit will have (1/ 4 + 1 / 4 = 1/0,5 1/0,5=2) 2 ohms

 

Doesn't work that way when a cross-over is added into the mix if the cross-overs are designed correctly, passive that is. The amp will still see a 4 ohm load in the situation you describe above.
