[QUOTE="sinosic, post: 3155821, member: 572675"] with a volt meter on the amp pos and neg it droped to 8.9 volts on a hz sweep. i know my amp it rated at 1000 watts @ 14.4vdc at 2 or 4 ohms. so when the bass drops low with the volume at full tilt my sub is not getting 1000 watts. i have read that this is very bad for your car and audio elctrical system. i have a 120 amp alt, big three, reg heavy duty car battery (not yellow top). my amp may be another problem being that its a class a/b 1000 watt rms amp (old soundstream rubicon 1002). im not sure but i think its ******* up aleast 100 amperes to beable to do its rated watts. long story short when i first got into car audio a few years ago i bought a power wire for my amp at home depot (cheap bastard). 4 gauge wire that was a b1tch to install because the threaded wire was about 10 total thick copper strands. other 4 gauge power wires i have seen are thicker and the strands of copper are fine and theres alot more. i know fine stranded is better because it more flexable. heres my question can my 4 gauge home depot wire be part of my voltage drop issue? sorry for rambling [/QUOTE]
