CAR AMP B CLASS 190W.jpg

Hello, Im a beginner and im want try to build this car amp, i have few question about the component value and types base on the attached picture, do you able to know what type of resistor and value is that? Too bad i don't have the schematics.

Question 1 : What kind of resistor is this? is 33ohm? High Watt?

Question 2 : What kind of resistor is this? 470ohm? what is the value? High Watt?

Question 3 : What kind of resistor is this? .5? what is the value? High watt??

Question 4 : What kind of resistor is this? is 50ohm? High Watt?

Question 5 : What kind of resistor is this? is 10ohm? High Watt?

Question 6 : How many turn for this coil?

Question 7 : What kind of resistor is this? is 50ohm? High Watt?

Hope to hear from you soon, thank you.
