Whatare the resistor values? - Rockwood X-Plore AMP-4030 Car Audio Amplifier

Resistors R1, R2, R3, and R4 are arranged in a circuit as shown in the figure above. The direction of positive currents I1, I2, I3, and I4 through the resistors are shown. (i.e., negative current values correspond to currents in the opposite direction to that shown above). The values for the resistors and the batteries in the circuit are: R1 = 100 ?, R2 = 200 ?, R3 = 30 ?, R4 = 400 ?, V1 = 4 V, and V2 = 12 V.

600 ohms

A resistor with a number code instead of a letter code is a SMD:
Surface Mount Device. You might have searched for SMD resistor code and got some hits.
The system for SMD resistors is:
1st value-2nd value-multiplier
6 - 0 - 1 following zero
= 600 or 600 ohms
603 would be 60,000 Ohms or 60k
6 - 0 - 3 following zeros

Are there any colors on the resistor or it is missing. If you know what the voltage and current should be in the circuit you can calculate the resistor value.

Go to the Radio Shack site and you may with the model number find a schematic or you can email/contact them for the value of the resistor.

I predict it is a precision value and type you will have to get from them if available.

PS: you posted in wrong catagory as this is TV section.

The value = 0.21 ohms 5% tolerance
Use this WEB site to work out the value of the resistor.

This WEB site gives you the color code values for resistors.

Sounds like your over half way there lol..
You now need to check the resistors positioned near the convergence ic's. They are your likely problem and go bad often when the ic's fail.

They are normally about 2watt and the values will vary but normally are like .10 ohms to 1 ohm.
I cant find a schematic to give you the exact values and locations but if these resistors measure off value at all you need to replace them with the exact value of the originals.

Heres a link to resistor color code guides just in case the value numbers are not printed on the resistors

Good Luck!!!

it's very difficult to give the exact value of that resistor.,but i can give some tips to find the value of the said resistor .( find how the resistor works, it is a dropping or fusable? if fusable used .47 or 1 ohm resistor if it is a dropping resistor you should make a trial and error .from 100k,10k or 1k.

if its a 4 band resistor, use the following calculator...

if the resistor is a 5 band, use the following link....

hope this helps!

It is recommended to use the same value due to the function of the resistors and their values.
A lower value will let the current flow a bit faster and the higher value will slow it down according to their design.
Try installing the same value of 220 ohms.
Hope this helps.
