[TPH1995]

Car: 2006 SV6 VE Commodore

Whats about to be installed:

Cabin:
- New Fascia
- New Headunit
- 1200w 4ch Amp - (100wRMS x 4)
- 4 x 320w Max Speakers - (70W RMS)

Boot:
- 1600w Monoblock Amp
- 2 x 1500w Subwoofers (500w RMS)
______________________________________

Other things that could (maybe?) Effect my batterys life/output that I have already or plan to get this month

- LED Aftermarket Tailights
- LED Aftermarket Headlights
- Footwell Lighting
- Constantly Running OBD2 Sensor (Displays on headunit)
- Adding GPS/Bluetooth/Wifi Receivers for the new headunit (the car had none of these stock)
- Full interior & boot LED light conversion kit (changing any light i can get to to LEDs)

And I think that's about it im sure ill probably need to change my battery just not sure how big id need to go or if going to big is dangerous, hoping someone here can reccomend a battery or maybe a tool that checks how much power in total my car draws in so I can buy a battery to match? Idk if that's a thing lol thanks for your time, any help is appreciated

Not the battery, but maybe the alternator, as the alternator is what actually runs the car, rather than the battery. Unfortunately I'm not auto eleccie, so I can't say whether the stock alternator will keep up with those modifications....

Ask a sparks for advice.
He can fit if need be.

If you are a bass head, get a mega cap!

Lots of room in the boot for a deep cycle battery

You want to look at the peak draw not the sound output of the unit/amp (usually the fuse gives that away). Then do the maths. I think the stock alternator is 100 amp for a peak 85 amp draw so there's not much room to play with. LED are low draw but the always on might have implications for your battery. Agreed, have a chat to a decent sparky
