tvcincy Posted April 15, 2012 Report Share Posted April 15, 2012 I just wanted to comment and share my results on upgraded the big 3. I just did my big 3 upgrade today. i have an 08' chevy impala. i did not use speaker wire for it is way to expensive for 1/0. so i went to home depot and got some 1/0 600 volt stranded copper and used it. before i upgraded i was getting 12.2 volts to my amp. After I upgraded i am at 15.2 volts. This seems crazy. Are these typical results? I am using stock battery and alternator as well. what kind of results have others gotten? thanks Quote Link to comment Share on other sites More sharing options...

new guy Posted April 15, 2012 Report Share Posted April 15, 2012 i bet your first test was with the car off and the 2nd was with the car on. 15.2 volts does seem a little high though Quote *current* 1991 honda crx si 2 skar audio 12s pioneer 6.5s dual 400 watt amp audio technix db 1/0 wiring kit. dual head unit Link to comment Share on other sites More sharing options...
Bump4life Posted April 15, 2012 Report Share Posted April 15, 2012 considering you have all stock electrical i would say 15.2 volts seems unusual. in addition depending on what type of amp you have it may not like that high of a voltage.

VIPmeetSPL Posted April 15, 2012 Report Share Posted April 15, 2012 would the voltage dropping from when the amp is really in use kinda defeat the purpose that its a 15.2 would it recieve what it is getting when system is in full tilt?

bass_stalker Posted April 15, 2012 Report Share Posted April 15, 2012 i dont know if that car has the ecu controlled charging or not, i think if it does there is a specific way you have to do the big three, i'm not 100% sure about it though Quote JEEP BUILD PROJECT ANTIBLING.2000 jeep Cherokee.HEADUNITAlpine Cda-9886SUBSTAGE1 acendent 18" audio mayhem motor with a TI basket and tantric parts1 prototype DAT hellfire 1000.1HIGHSStockELECTRICALdb link 0 gaugeKnuconceptz Kolossus 4 gauge1 xs power d3400 under hoodBig 3 upgradeold fourwheeler build The only way to delete your SMD account is for you crawl to steve meades door step on your knees and pleade for his forgiveness and acceptance to be released...He will either grant your wishes.....or choke you with a large piece of 0 gauge and electrocute you by hooking up a solid gold DC 12k at 0.000001 ohm and 10000 volts to your eye sockets and blow your head apart You guys act like you have never clogged a toilet and ran around the bathroom frantically hoping it don't overflow.

tvcincy Posted April 15, 2012 Author Report Share Posted April 15, 2012 thanks for the responses. I took both before and after readings with the engine on. this is not the voltage when it's hitting hard bass. it's just at an idle volume. it seemed really high which is why I ask. I have taken readings multiple times. I have an old PPI PC21400 and an old Sony XM-754HX. Both of them read 15.2. I didn't see any voltage specs in the PPI owners manual. I was looking at getting a Crescendo BD2000d because I have been given multiple referrals to get this amp. I know that it does good at 13volts +.
