Hi, I recently aquired a 69 which has a 900w Powerzone Crunch amp mounted in the trunk. It looks like an electical nightmare and a possible fire hazard and I am considering having it removed. Also does not sound as good as the BBC roaring:D. Does anyone know what kind of power these things pull and would it be wise to get rid of it??(I was told it is on whenever stereo is on) Thanks for you opinions on this!!

Amplifier ratings can go from low to high and some can be actual ratings or rated when lightning strikes them. Some 900 watt rated amplifiers may draw 20 amps while others could draw 200 amps. It's an advertising thing sometimes.

I would look at the amplifier and see if there are any fuses in the chassis of the amplifier. Most newer amplifiers run the ATC plastic style fuses in them. You might have a single 20A, a 30A, twin, triple, or more multiples of particular sized fuses.

Most amplifiers will draw more power when the volume is turned up and they put out more signal to the speakers. Think of it just like a car. At idle, you are not sucking hardly any gas from the gas tank but at WOT, you need more fuel.

If you are worried about the system being safe I would see if there are fuses on the amplifier. If there is a 30A fuse on it, they should have run a 10 gauge or larger wire from the battery AND placed either a 30A or 40A fuse close to the battery inline on this power wire. A fuse on the amplifier only protects the amplifier and what's past it while the battery fuse protects the wire going back towards the amplifier. If there is not the proper sized fuse close to the battery then the wire is unprotected and if it would get pinched could cause an electrical fire.

If you cannot find fuses on the amplifier, see if there is one close to the battery, and if none are found I would disconnect the amplifiers feed wire, contact the manufacturer of the amplifier and see what they recommend.

Thanks for the reply, Jim. I checked it out and it does have the large fuse at the battery and at the amp. It appears to be professionally done, I guess I will leave it in place to listen to when I am waxing the car!!
