Powering an amplifier, main battery or leisure?

[Pedro20001]

Hi all, just adding 2 small amplifiers to power the sub and front components, just wondering what people do; power from the vans or from a leisure battery? I have a 100ah lithium battery under my drivers seat. Thanks in advance for any advice

Mine's on the main starter battery and I don't run the amp unless the engine is running as it flattens it in no time.

you can take the feed from either, provided its fused and cabled correctly.


assuming the lithium has a dc-dc charger etc etc. . .


if it was me id take the power feed from the closest source.


so id mount the amps and sub under seat, take the power from the lithium, use chassis as ground, then run the sterea feeds along the cable tunel up to the radio.

Thanks everyone for the advice. I'm going to put it off the leisure battery .

Personally we take it from the leisure , not because it’s easier but less chance to picking any noise up . also will not flatten your starter battery if you decide to run it for a while when sat up

Holy thread revival Batman!
Excuse my ignorance, as I don't fully understand electrickery.

I have just purchased replacement Speakers and Amp from Vibe.
Aiming to install and sound deaden the bejesus out of the doors, as and when there is a break in the weather.

I too am thinking of going off my leisure battery, the current set up in the van consists of a Durite automatic battery charger 12v 10amp, along side the Durite VSR (voltage sensitive relay) 12v 140 amp.
Silly question No1 - Will this kit allow me to run the amp off of the leisure battery?
Even sillier question No 2 - Does the isolator switch need to moved to on/out, or can I leave it in the off position and the amp will still draw power from the LB?

Told you I know sod all about electrics.

You can run anything 12V off your leisure battery surely, so powering the amp will not be a problem The Durite stuff is just a means of charging the LB.
If you wire the amp direct to the battery with a fused connection, or you wire it upstream of the isolator switch then it will still work. It depends where your isolator switch is in the circuit.
