Let me start out by saying hello to everyone, as I am new to this site. I've done a lot of searching and just can't nail down an answer to what I am trying to do. I own a 2008 Nissan Altima Hybrid. I currently have the following installed in it -
Pioneer AVH-P4400BH Head Unit
All stock speakers have been changed to Infinity Kappas (dash, doors, and deck)
2 Alpine Type R (SWR-12D2) 12 inch Subwoofers
2 Memphis PR1.1000 Amplifiers (1000w RMS)
Power Acoustik 300w RMS Amplifier on my door and deck speakers, dash speakers powered by HU
Swapped standard 12v battery to a HC2000 Kinetik battery.
My hybrid car does not have a alternator, instead it powers accessories and charges the 12v battery by getting it's power from a DC-DC Converter. The Converter takes power from the Hybrid battery, converts it and sends it to the 12v system. I cannot find any exact amp rating that the DC Converter is putting out, but did locate a 120A fuse under my hood.
I originally installed all of the above using the stock battery and my voltage was going from 14.4v to 12.5v on big bass hits. After upgrading to the HC2000 Kinetik battery, voltage goes from 14.4v to 13.5v. Is this good, bad, acceptable, alarming? What is your opinion on it? I can say my headlights dimmed with the stock battery, with the HC2000, no longer happens.
I would like to actually at least feel I have the options of adding more subs/amps in the future and thus, this is where my dilemma starts. Since I do not have a traditional alternator, can't get a bigger one. I can't find any information online regarding upgrading the DC-DC Converter for higher output, don't even know if that is possible. Is performing the big 3 even possible on the Hybrid? Really hope someone who knows much more than me can shed some light on this situation. Thanks for any help anyone can provide.
