A cap may help how your system sounds slightly, but if your existing alternator is lacking a cap is no substitue for a higher output replacement and could actually make things a bit worse. If you have a domestic vehicle this is fairly inexpensive place to start looking: http://www.motorcityreman.com/ -Fishy |

Silver Member Username: TheelfkeeperStockbridge, GA USA Post Number: 236 Registered: Feb-05 | wattage/12.6 = amps plus you have to take into consideration the car electrical pull 1400/12.6 = 111.2 800/12.6 = 63.5 |

Silver Member Username: TheelfkeeperStockbridge, GA USA Post Number: 240 Registered: Feb-05 | yes, that requires power too and it gets it from the same place the stereo does, battery/alternator. |

Silver Member Username: Suleman36Post Number: 564 Registered: Feb-05 | Ok question? should i run my jl 500/1 or my zapco referance 500m class a/b mono amp??? the zapco does 500rms at 4ohms and is underated and can do 538rms and at 2 ohms it can do 700rms. The fuse rating is 40A for the zapco though. Which one of these amps whould be more efficiant if i run it to a avalanche 15 800 watt subwoofer.????? my stock alternator is 80 amps and im also running my ppia300.2 for componants.. and i will use my batcap 800 stereo battery in the back..thanks |
