Silver Member Username: Bakerj72Regina, Saskatchewan Canada Post Number: 121 Registered: Jun-05 | To start I will tell you what i have... 00 Acura Integra SE (B18B) same as GS 9835 Alpine HU 500/1 JL ---> 10W7HO 1.2 farad stigner cap stock batery stock 90 amp alternator Second, I replaced my back up radio fuse from a 7.5A to a 10A (I kept blowing it) Third is my problem... At volume 20/35, my lights dimmm pretty bad. At volume 25/35, with a hard bass hit, my HU turns off(un-tilts) for 2 seconds and turns back on at -- volume. Had my Car at idle playing music at 20 volume for 15 mins and then the HU started turning on and off. I am thinking it might be low amperage comming out of the alternator. I have told this story/problem to many many people in town and I have recieved multiple replies... - new alternator (old one is not putting out 90A) - H.O. alternator - Put a capasitator close to the battery - A 12v wire is beeing grounded - New battery because the old one is finished - New dry cell deep cycle battery I am thinking of giving the local Alternator/Battery guy 15$ to see how many amps my alternator is putting out or get a friend to conect his car battery to my battery and see what happens(would tell me if its my car not producing enough power.) I need help! Where do I start? What would you do? (btw... If I have to get a new alternator, how many amps would I need to run a 300/4 and a 500/1 for future project)? |

Silver Member Username: Bakerj72Regina, Saskatchewan Canada Post Number: 122 Registered: Jun-05 | Im only running 500wrms I shouldnt have to be buying a new alt or battery... Is it possible that wiring could be mangled somewhere...? |

Silver Member Username: Dustin3Tigard, Or U.S. Post Number: 769 Registered: Oct-05 | lol mark. i was just a lil quicker. and justin, a yellow top battery would be great for some extra power to store if you have any room. usually when i did my whole electrical system i got a new battery, alternator, big 3 upgrade, and then i could get a yellow top. |

Silver Member Username: Dustin3Tigard, Or U.S. Post Number: 770 Registered: Oct-05 | i thought you said you have a 300/4 also???? its possible that the wiring or sumthin could be damaged, but the way you explained your problem to us, it def. sounds like a alt prob. and like i said, that cap. isnt helping |

Gold Member Username: RzarectorCoquitlam, Bc Canada Post Number: 1043 Registered: Dec-04 | why not? i was runnign the same amp with my 88 mustang and my lights were dimming prety bad.. and they have more powerful alternators.. like i said some cars will have tight tolerances for electrical supply. u could try to upgrade the wires and see if it helps pass more current i.e. 4 gu from alt. to battery, from batt negative to chassis. from chassis to engine. but i doubt that will fix it, it sounds like your straining the system bigtime.. keep in mind u WILL take out your alternator and battery if u keep straining it.. i was driving one day playin some music,, puff of smoke comes outa the hood ,, i get home car doesnt start later and both the alt and battery are wrecked, so keep that in mind |

Silver Member Username: Dustin3Tigard, Or U.S. Post Number: 772 Registered: Oct-05 | good point. like mark said its all with the car because my friends 80 amp alternator in his jeep with a 800 watts amp doesnt make his lights or anything dim at all, but it def wouldnt hurt your WHOLE CAR to get a new HO |

Silver Member Username: Bakerj72Regina, Saskatchewan Canada Post Number: 123 Registered: Jun-05 | I now think my alternator is putting out 30 amps or something supidly low. Worth getiing it respun? Today I plan on having my alternator tested... and I live in Canada so im guessing I should just stick with a red top. And... the 300/4 and XR's project is meant for a year from now because I have 4200$ debt and im in high school working a 9$/hour job and im involved with sports... no time no money! For now I just wanna "Mabe" get an alternator to power the 500/1 or just stick with the one I have now and let my ego chill out in volume 20. so... get a red top and a new alternator or respun alternator? Oh and when I get my alternator is it worth it to run 4AWG from the alternator to the battery? |

Silver Member Username: Bakerj72Regina, Saskatchewan Canada Post Number: 124 Registered: Jun-05 | Ok, It's good friday and everything is closed... Sweet. And no, I'm not bringing my car to future shop or Bestbuy, they know nothing. Just called My other local shop and he told me it was an HU problem or my Ohm age was wrong... It's a single voice coil for gods sake. Any ways, it turns out my brother bought a new battery and I hooked it up to the one in my car and I hit full volume! So now at lest I kow its my car's power sysytem. |
