Don't ask why but after a big head ache

(cause my car was broken into) I had to rewire

my HU from the fuse box.

1. do you guys see a problem with this.//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

2. where do I conect the mem so that the

settings and the radio stations don't reset

everytime I turn off my car?//content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif

I have a cheap JVC HU (spare i had lying around since mine was stolen)

and My car is a 88' Mazda RX-7.

Your main power should be linked to the ignition. the memory that you talk about should be on a constant 12V. THe ignition power will oonly have current when the key is tunred. That way, your system will shut off, whilst the constant 12V will allow memory to stay on.

 
I know about all that I all ready conected it to the

same audio fuse and it works fine but what 12v constant

do i conect the meme to?

Direct to the battery?

Thanx for the help

yes, the 12V constant COULD be directly from the batt, but it would be a safer option to hook it up to the fusebox audio fuse out. If it's too ahrd to find it, then I guess you've no option but to connect direct to the batt. I think the same rule should apply as amp power lines. Fuse it within 18 inches of the batt terminal. My hu's constant 12V had a 15A fuse, if I'm not mistaken.

 
Thats exactly what I needed to know thanx man.

I have HU already wired to the audio fuse but i guess

i'll just use another fuse for the HU and the audio one for the memory.//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
