how important is a capicator.?
want everyone's suggestions.. im gonna be running my same system in my 95 that i had im ny 88 sse.. but i never used a cap.. i will be running 2 15'' kicker dual 2 ohm L7 subs with 2 kicker sx1250.1 amp's with a 80 amp isolator and 2 batery's ( 850 cranking amps and 1000 cold cranking amp's) each battery... i never had a problem with anything shutting off or my amps going into low voltage but i want to know if i should use some caps for the install on the 95 se.? oh and its a 140 amp alternator..
use caps or not.? will it give me more power and volume.? thanks guys... |
ur extra battery will help with capacitance. but from my experiance, the biggest difference will be in the alternator. and even tho that is a 140 amp alt, it WILL NOT have that much putput. that is max rated output. it will actually put out 70% of that. so it will be about 100 amps effective. i would suggest a rebuild to boost the ampherage output. that will provide the most difference in your draw on other electronics.

You should at least get a smaller alternator pulley to see if you can charge up everything a lot sooner. It should help the car keep running just fine with a bit heavier power draws.

Our alternator, just lilke our old S1's, don't like to spin too fast as they are.
Best bet is to find an Iceberg kit and do some upgrading to that alternator ;) |

are those kicker amps 1250 watts rms or max?
|
Kickers are rated at RMS. What you see as the designation on those amps, are the RMS watts ;)

**edit**, but actually, i once used a clamp on amp meter, and my system was drawing a peak of 90 amps. and i have 2000 watts of rms. |

keep in mind you have to figure in efficiency when you want to know how much current you amp wants to reach "rated" power. since it's a class d amp, efficiency is going to be about 80%, depending on design . 1250/.80=1562.5 (its going to take 1564 watts for this amp to make 1250) 1562.5/14.4=108.5 so what this tells us is that for your amp to produce its 1250 watts, you will need at least 108.5 amps of current and you have to have it running on 14.4 volts, which is supplied while the car is running. dont go with a capacitor, get your current supply up man! ;) |
