Sassmaster is correct these are not usefull in Car audio since they do not measure DC current

If he already has a good digital multimeter, try the Fluke i410 AC/DC Current Clamp

If you are more comfortable buying in a store, there are many in the Toronto area
Go to www.fluke.com and go to Canada, where to buy.. enter province and city.

Tenaquip, Future/Active electronics etc many many places sell Fluke.
