Some of you may know, that Ive been away from playing for years, and am trying to get back. I have an old Peavey 400 2x15 amp that sounded like crap, so I took the head to the shop. Shop man charged me 50 bucks to clean it up, and it sound fine thur his Ampeg speakers. I get home and its still distorted, so Im taking it back to the shop Saturday. Help me out here if I need new speakers, Im confused about ohms: The back of my cab says 4 ohms, but my head says 200 watts @ 2 ohms. Ive seen replacement brackets for the 4 ohm speakers, and 8 ohm replacement speakers, but no 2 ohms. So here are my questions: 1. The higher the ohms, the less wattage, so why would anyone use 8 ohms, and what would be different if I put them in my cab (other than watts)? 2. How do you get to 2 ohms with this setup? 3. The 4 ohm baskets are $110 each, so would it be better to use different speakers. I know I need a better amp, and will probably get one later, when I prove to myself that Im back.
