Question about Profile - California: 2 Channel 1200W California Series 1200 Car Audio Amplifier

1 Answer

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 sharp on heavy/loud notes. eventually the subs stop hitting completely yet the red power light on the amp stays lit. Got me puzzled. Any ideas or solutions are most welcome!

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.

How do I wire these mtx 6000 10" inch subwoofer to

The wiring configuration is highly dependent on the amplifier being used. The subs can handle 250 Wrms each, so I would not recommend putting them in any configuration that results in power levels higher than 250 Wrms per sub.

Is my amplifier blown?

check to see if your rca inputs move sometimes i have had problems when moving amps on damaging those. but it sounds like you do have a blown amp sometimes when moving it you can hurt it. recheck your connections and try making sure you dont have a short in your wire.

Subwoofers Creating Independent Noise

Sounds like your RCA's are near your power & ground wires. I would run your RCA''s on the other side or as far away from the power wire as possibly. Sounds like your getting the infamous alternator whine. If none of the above work you can get a in line noise filter to filter out that noise. RCA's can pick up noise when their around anything that has alot of current running through it....Hope this helps

Check the 12v wire running from the battery to the amplifier.
