when i install my headunit i'm going to put a inline fuse on the accessory wire when i hook it up to the windshield wiper fuse. i'm also going to put a fuse on the remote wire going from my headunit to the amp.. i'm going to use a 10A fuse for both of these.. is this a good idea to do this?

 

Placing a fuse in-line is not a bad practice on any curcuit, but placing two in line is redundant. You should not use the wiper curcuit at all. If you pull off the panel of the center console on the passangers side and access the fuse block/BCM, you can use an empty fuse slot for your accessory power. I say this because at work today a customer came in with a Airbag light on and I found the fuse blown for the Airbag module. A stereo shop(a well known one at that), used the airbag fuse for the new radio's power and over loaded the curcuit. They also managed to damage the terminal in the fuse block, which is part of the BCM. The BCM needs to be replaced at around $250 for the part + labor and reprogramming. Just be carefull!

 

the other slots for fuses have no power going through them at all.. the only ones with power are the ones being used from what i have been told. could i just run the turn on wire for my amp from the battery and just put a switch on it?

 

I didn't fuse the head unit, but I did hook it to the proper side of the fuse. I did fuse the remote lead that runs back to the amps - but I did that to protect the remote turn on circuit of the amps as opposed to fire from a wire heating up. A 1 amp fuse should be more then enough to turn an amp on. I forget already but my fuse is either .5a or 1a and that's turning 2 amps on.

 

really i didn't know they had fuses that low... are they normal fuses that are used in cars? the right side is the proper side for placing the fuse tap correctt? if i run the wire for the amp off of the right side of the fuse i won't need a inline fuse on that wire will i? does the amp turn on wire draw a lot of power?

 

Yes, the right side is the proper side. And yes they are normal glass BUSS fuses. If you run the wire off the right side technically you don't need a fuse but I put a small one in that might give some protection the amps' turn on circuit. And no, the amps' turn on wire does not draw a lot of current, hence my suggestion of a .5 or 1a fuse.
