[QUOTE="grandam888, post: 7143329, member: 628519"] Alright, my amp is a rockford t15002 2 channel amp. 1500 watts rms @ 2ohm bridged, and 1 ohm stable stereo per channel and 750 watts rms. When i turn my car on, amp makes a high pitched whining noise(coming from inside amp, not from speaker.) and volts on volt meter drop from 14 volt to 10 volts. and i am not even playing music through it, head unit is set at 0 volume when this happens. i almost think i have a short somewhere inside the amp, before this started, amp worked fine except when turned up it would draw every bit of power out of may car down to 10 volts, so i stopped turning it on @ all to avoid damaging the amp. rms is 1500 watts so its pulling in the ballpark of 100-120 amps when turned up, and thats just rms. Also i have a 117 amp alternator, so we know i am underpowered. i am almost leaning towards amp always having an issue with some kind of short as i have asked others about how fast it pulls down my voltage, and they find it odd that it does not play for more then 5-10 seconds. also i havent upgraded my big three, and i am running 0 awg straight from battery. just want some opinions before i crack this amp open and start trying to find the short. all help is appreciated. thanks [/QUOTE]
