the amp is 160 watt amp??? Thanks for any help
Look at what size fuse is installed in the amp, I would say around 15-20 should be suffecient.
If it aint a Chevy don't raise it up!
20 should be good for that size amp.
I know this may sound like a smart a$$, but read the manual. It will tell you what to use. If you go to big, it will drag and if you go to small it will blow out. Trust me been there.

If your manual doesn't say what amperage fuse to install, try this:
Watts divided by volts equals amps. 160W / 12V = 13.3A
Try a 15-amp fuse first. If that blows regularly, step to a 20-amp, but no higher. I'd use no less than 12-gauge primary wire to run your power to the amp, to ensure that the fuse goes pop, and not the wire.
The only thing I'd add is that the voltage in a properly setup car audio system should be 14.4v with the engine running....so modify your fuse calculation accordingly.
With the engine off, it is unlikely that even a NEW battery will show exactly 12v... Just a thought.

No stereo....but I'm already making plans!
I put in a 15amp and havent had any problems so far... Guess I must have gotten a good ground because I have absolutly no engine noise... Appreciate all of you helping out
Greg72, you're right. Had a bit of brainfade there... But I did remember Ohm's Law correctly, so I gotta pat myself on the back for that!!
