73' Charger Battery Issue...

Nacho....

So cap, new subs & amp.

Sounds great when running ,turn lights on & bass amp cuts on & off. Just a little move on the ALT meter.
I get almost 15 volts to battery when running and to the amp cap.

I have the Amp fuse by the alternator since I am running the amps from ALT to AMPs. Should I put the fuse closer to amps in trunk?

Maybe try hooking amp to battery since I have a cap now?

It is 119 in Phoenix if the heat could make a difference?

The bass amp is not even 200 RMS... :shruggy:

I have to be honest, I never have worked on auto sound to guide you better on this.

Thank you....that site is amazing. I am very into home & car audio.

With that being said and doing all my research it is found that aftermarket amps should be connected to the battery +, not alternator. Connecting to ALT can damage the amps and they will not get the correct current. I forget , AC is from ALT and DC from battery? The amps need the current from the battery.

I re-connected the bass and mid/high range amps back to the battery +. Sounds amazing. Now  the ALT gauge does go towards C at big bass hits. Although the headlights, interior lights, etc do not dim when radio is cranked and the bass hits.

My amp capacitor was defective, do not have one now. I will be purchasing one to see if that helps with ALT gauge movement with bass hits.

Nacho, thank you. As it does turn out AMPs to battery +.

The battery is at 15 volts with all accessories running & amps going.
Battery is at a solid 13.5 not running and is keeping a charge even in my 120 degree Arizona garage.

I think I finally have all my electrical correct and sounds system working properly !  :cheers: :2thumbs: :2thumbs:

Well sounds logical the cap should be conected to the batt side, being is just like a small battery buffer.
