Question about Profile 600MSX Car Audio Amplifier

1 Answer

Blowing Fuses I have had my Profile California 600MSX hooked up in my car for years. I have it pushing 2 12-inch JBL's in a ported box. A couple months ago the 45amp main fuse in the B+ line blew. I replaced it with a 100amp fuse and the 3 20amp fuses on the amplifier blew. Everything is still connected the way it always has been. I have tried everything to get my amplifier working again. Please help.

Re: Blowing Fuses

If you disconnect the speaker wires from the amp and the fuse blows only after the remote voltage is applied (when the head unit is switched on), the output transistors are likely shorted.

Why does my inline fuses keep blowing on a jbl gto 14001 amp

You need to calculate the amount of amps being driven through that fuse + the amount you need to feed the amplifier.
In my Volvo S40 and V70 I had no problems driving an amplifier of the rear power connector, but on my Honda S2000 however I had to create a different connection all the way to the battery line for a smaller amp (connection as in cables, condensers/filters and fuses).

I have a 1000 w mono california amp is it 1oms safe or 2oms safe

It is always safer to use higher Ohms as it loads the Amplifier less.But you will get the rated power only when you connect the recommended impedance speakers. Eg: If the specs says 1000watts @ 2Ohms on connecting a 4Ohms speaker the Amplifier will only deliver 500watts.But will run cooler and is of course safer.

I have a California Profile 1200w amplifier. I'm operating two 10 inch Sony SP5 4ohm subwoofers unbridge. The amplifier hits hard for about 30-45 minutes then it partially shuts down. Bass also drops off...

Overload. Looks like your amp is 4 ohm stable. You are wiring each speaker separately from the
amp (Left + and - to one and Right + and - to the other) and if so you are correct. You may need
to increase the available amperage to your amp with a larger guage wire. I am assuming you are using 4 gauge. If not, bump up to 4 gauge. If so maybe add a second, sealed cell, battery as a stiffener. The capacitor idea wont help enough for the $$ invested. The battery should give you reserve amperage and keep the system happy. Be sure to run a fail-safe (250 amp) fuse at the battery just in case a wire shorts to a ground, your car wont burn to the ground. Just wire the battery to a system connection and the both go to the amp. It will also give your vehicle electrical system a much need boost that will save your alternator.

My Jbl mono amp cuts out

It's likely that the amp has blown output transistors. To eliminate other possible problems, read through the following page:

California 3600 mosfet discrete 3 ch amplifier 600 watts does not work

It sounds like it's going into protect. To be sure it's not the wiring, disconnect all speaker wires from it. If the light still goes out, check the DC voltage on the B+ and remote terminals. Place the black meter lead on the ground terminal of the amplifier. If the voltage remains above 11 volts as the amp tries to power up, the output transistors are almost certainly shorted causing the amp to go into protect.
