Re: 72 Coupe Speaker Question

I think most of the die hards will suggest against using the 4 ohm speakers. Many advise that it is hard on the transistor / amp. It can cause it to overheat.

I am no expert and am sure one will chime in with better advise.

Ed,

There are brand new 10 ohm speakers available through GM, so I wouldn't see a need to use 4 ohm speakers. In theory, you "could" use them but you're much better off with new ones or to have your originals "reconed."

Re: 72 Coupe Speaker Question

Agree! The design center was for 10 ohm speakers. Substituting an 8 ohm speaker (very common) gets you so close to the design center, there's little, if any, affect. But, dropping down to 4 ohms is wandering a bit too far off design center in my opinion...

Re: 72 Coupe Speaker Question

Bare in mind that if you're considering the use of aftermarket versus original or GM service replacement speakers, it's going to be hard to find off-the-shelf 10-ohm units... Most of what's sold in substantial quantity today come in 4, 8, or 16 ohm nominal formats...
