Quick Help Needed - Stereo / Amp Power

[Shaun16v]

Just after some quick advice, my girlf's 206cc has gone into garage today as it keeps blowing a fuse which covers all instrument dials, stereo, aircon, interior dash lights and hazard light switch.

The garage say its blowing because of the stereo, and everything else is fine. I expected this would be the easy way out they would take rather than actually looking into anything.

So, i need to find out some figures on the actual amount of power the head unit would draw, and how this compares to the standard unit.

Its a Clarion Cd/flip out TV head unit, and runs 2 amps. Now although the amps get their power direct from the battery, how much power is taken via the remote to turn the amps on? I believe this is minimal but was really after an actual figure??

Im sure that the headunit she has and the remote to the 2 amps, can't really use any more power than say the standard head unit with a changer attached, as the changer would also take its power through the head unit.

Also, its all been fitted for about 6 months with no probs, its just started blowing fuses in the last week!

Any info/advice would be greatly appreciated as have to pick the car up in a couple of hours, thanks

at a guess the remote turn on built into the amps is pulling about 40 mA down the remote

i'd guess that the new head unit would pull more power if it was using the internal amp but without it i'd say it would be about par (10A max)

Right, just found the headunit on the Clarion website, maximum power consumption is given as 4A.

Sorry to be thick, but how does the 40 mA convert into terms of Amps? Is it 100 or 1000 mA to 1 Amp??

Either way, i dont see that
1) TV Headunit with NO internal amp,
2) remote to 2 amps

would use more power than

1) standard cd player with internal amp and
2) cd changer powered through h/unit

Just need to clarify as much as possible before i go down there

just re wire the stereo direct to battery and see if that makes a difference using its own inline fuse, then see if this blows , i carnt see it though more likely to be crossed wire/nipped wire

Well if they still say they're not going to look at it anymore, i'll take it away and just disconnect the amp and h/unit for a week and see what happens. I really just want to blind them with some facts and figures cos i knew pretty well that they'd just fob it off onto the stereo.

40mA = 0.04A
400mA = 0.4A
4000mA = 4A
1000mA = 1A
