Bronze Member Username: SomedonniedudePost Number: 59 Registered: May-07 | It could be a voltage problem. Im my old car my rockford amp got hot and i fried it and smoke came out. even my kenwood got hot in that car but it never fried, just protect mode, but in my new car never had a problem with either. My old car has a 65 amp alt with some cheap 5 ga. wiring, new car has 11o amp alt and bought some descent 4 ga. What kind of car do you have and what all you got for electrical? |

Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 551 Registered: Oct-05 | so none of u think its the actully amp then because it gets extremley hot and makes teh subs sound ugly. And i have a 90A alternator and im using 2 Gauge wire for everything |

Check voltage at the amp and bat. Check bat voltage at idle and off. It may be the amp. But you need to see if its in spec as far as power/ohm/ground goes. If they are all good then its probly the amp. 90 amps is realy pushing it for a 1500 |

Bronze Member Username: TejcurrentPost Number: 72 Registered: Apr-07 | I'd check to see if one of your subs is out of phase. I'd make sure the +s and -s on the subs are wired up right. That would be the first thing I'd check if it's not that loud, because even a severe voltage dip wouldn't make it sound that bad right off. Then check to make sure you've cleaned up the ground connection really well, and that nothing is cutting into your power wire shorting it out. If that doesn't help, then try swapping out another amp to see if it works, and if not then you know it's wiring related. Like I said, if you're too lazy to remove the subs from the enclosure, use a dmm to check the ohm load. on each individual one. |

Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 552 Registered: Oct-05 | i removed the subs yesterday and today and they are Dual 2 ohm and i have them wired at 2ohm load. I guess i can try to find another ground spot to see if that helps but who knows |

Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 554 Registered: Oct-05 | i dont think so im about to test my friends zx1000.1 on my subs to see how that sounds so if that pushes my subs good then i know its the amp but if it does the same thing as my zx1500.1 then its prob the ground or sumthing |

Silver Member Username: Cplaya280Quakertown, PA USA Post Number: 555 Registered: Oct-05 | I found out it was the amp the whole time i knew i shouldn't have trusted refurbished i know it was the amp cuz i used my friends zx1000.1 and it powered the subs pretty nicley |
