In my first setup i had a 1000watt Rockford Fosgate AMp powering 2 10" sony subwoofers rated at 1100watt max & 300rms. They sounded good, but there just wasnt enough power. So i upgraded my amp to a 1500watt. Now when i turn the volume up to a certain point, the subs cut out and then there is no sound from them. The subs also cut out when i turn the car sharply. I have messed wiuth the gain and crossover frequencies, but i cant get it to stop. Am i just putting too much power to the subs, or should i have upgraded my wiring kit when i got the new amp? Im haveing all sorts of car problems right now, and i suspect that the alternator is broke and cant provide the needed voltage. I dont know. does anyone have any Advice? THank you.

When you turn sharply?

Sounds like a bad ground or some other connection problem. Judging from the condition of your system by your description it could be a bunch of things, lol.

I think next weekend i will check alll the amp wiring, i ran all the wires through this maze of car interior, so maybe they got pinched or something.

wow, your way over powering your subs. Your match the RMS wattage of your subs to the output of your amp. You only need a clean 600 watts.

A friend told me that the subs could handle up to their max rating, but I think i believe you not him...

Does the max rating mean thats how much that they can output during high amounts of bass?

hehe that's pretty bad. I'm not sure if the PLC processes that or not, I'd guess so, so it would likely be an internal error or a wire crossed.

Maybe you blew up a relay. In that sense maybe it doesnt know where to send the electrical signal to.

hahaha. Alright well this is probobly the best guess on this post yet. When you turn sharply you are using power, when u stop/break/signal/ Anything with your vehicle, You are using power. Think about it, most amps and even vehicles have a shutoff system that when you vehicle gets to a certian voltage(low voltage). I will sacrifice music or even your break lights to keep the engine running. I no it does on my safari 98. Maybe your vehicle is losing to much power when you do certian things that it sacrifices ur music(turns it off) to still run the vehicle???

All in all, you alternater may be the main problem :P. Because turning your vehicle has no effect on your music signals UNLESS you have a bad ground and when you turn its touchin somthing or not enough of something :-)
