SnowDrifter Posted April 13, 2013 Report Posted April 13, 2013 To an extent, "losing your rpm" is normal. Especially in a smaller engine. The amp is drawing power, which the alternator tries to supply, and the alt gets its power from the engine. Do the big 3 and get an AGM battery up front. The bigger the better ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
Noel989 Posted April 13, 2013 Report Posted April 13, 2013 What impedance is your sub? D2, d4, etc? Build Log - http://www.stevemead...-cruiser-el-pt/
Enzo Posted April 13, 2013 Author Report Posted April 13, 2013 Sub is a dual 4ohm. The car is a 2000 Monte Carlo SS with the 3.8l v6 so its not a very small engine. Ive been reading and seeing that capacitors can fix a dimming problem. Also the amp wont take 0 or 1 gauge wiring. My 4 fits in it perfectly
Crandis16 Posted April 13, 2013 Report Posted April 13, 2013 You could also put a battery in the trunk I saw a big improvement after I did this on essentially stock electrical (big 3 done) My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL
Guest Posted April 13, 2013 Report Posted April 13, 2013 capacitor will do jack shit. rpms are lowering because the alt is under load which makes it harder on the engine to spin. and lower rpms will make the alt output less power since its spinning slower. 800rms shouldn't drop your voltage THAT bad unless you're clipping the shit out of your amp, or your wire is too small, or your ground is shit.
SnowDrifter Posted April 13, 2013 Report Posted April 13, 2013 I will also say this: a bit of light dimming is normal. My voltage is pretty solid (drop .2-.3v full tilt) and my fog lights and dash lights would still dim a bit. HIDs don't dim though ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
Enzo Posted April 13, 2013 Author Report Posted April 13, 2013 Hmm a lot to think about. I dont really have the money or do i want to do the big 3, so thats why i was looking at a capacitor to help a bit. I can get a 2 farad cap for 50 bucks. If it comes down to that i have to do the big 3 then ill have to just sell the setup
SnowDrifter Posted April 13, 2013 Report Posted April 13, 2013 Doing your big 3 costs ~20-30 bucks. And I'm sorry but not doing it isn't an option. It's a requirement. Stock wiring is designed to handle stock electrical loads. Not the extra 120 amps an aftermarket amplifier will draw. ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
mnrookie Posted April 13, 2013 Report Posted April 13, 2013 You would rather sell your stuff rather than do the big 3?!?
russtezecustoms Posted April 13, 2013 Report Posted April 13, 2013 Holey lazy hard heads batman!! Like said above the big 3 us just 3 cables under the hood. Like 30 !bucks. And not that hard to do. Look it up on here if your intimidated just ask questions and follow the advice your given. Good luck to you, and remember that this hobbie only gives back what you put into it.(that includes money and effort.) I just wish i had a funny sig.
