Another Car Stereo Question!

[coleslaw]

i just installed a new head unit in my car (JVC ElKameleon). the 12V Battery lead (the permanent connection for memory) has blown 2 fuses thus far. i am using the same ground wire from the car's wiring harness as the old installation. i am not talking about blowing fuses during playback... i'm talking about blowing fuses at power-up. this new head-unit is 45x4 while my old one was 25x4. would this have something to do with it? or should i consider grounding it somewhere on the frame? any suggestions would be appreciated.

1st, that is a quit powerful head unit, so you may consider a heavier fuse. 2nd, You should always ground stereos. Don't run it to your battery terminal.

i have been able to power-up the head unit now... but it doesn't appear to be getting enough power. the control panel does not flip down like it is supposed to and the color display is very very weak. do you think a heavier fuse would solve this problem? i was thinking about putting in a 15 amp fuse for the one currently at 10 amps. the only concern i have is the safety warning that using the wrong fuses my cause problems, such as fire. have you ever used a stronger fuse before? is it safe?

It is actually a 40 W x 4 max power output. Not that it makes that big of a difference...

didn't you get a spec's manual with it, or an installation manual?? first of all you should never ground to the battery directly(if thats what you where doing), get a cheap voltmeter from radio shack and test the output of the power wires. I think its the deck thats messed up.
