	quote: Originally posted by AdiSRI its a load of bollocks. I was alking to some ice people at a local shop and they say that the actual power output from the unit is like 4 x 23w RMS, the 4 x 60 is peak. Thus the current draw from the unit is well below the amount necessary for a direct battery connection. i dont thnik mine has one and its perfect, never really looked tho. my alpine was previously fitted in my primera, the power cable was less than 1mm squared. i'm sorry but there's noway i would connect that to power a head unit with a built in amp. it's a fire risk to start with if the wrong sized fuse was fitted by mistake, never mind powering the head unit. what size cable is the feed for the head unit in a corsa btw?

	The new alpine 's (9812) needs to be connected directly to the car battery because the internal wiring loom is not powerful enough!

	yes i have an alpine in the wifes golf and had to run a fused supply from the battery,they specify a certain gauge i think and the standard radio loom power cable is a bit light for the amp's needed to power the head unit amp. [Edited on 06-01-2004 by corsafreak]

	yeah, with the alpine units they need to be hardwired to the battery. get a fitter to do it :P

	they need direct battery connection, my dad has one it does work with normal loom but, when you crank it up it turns off.

	:) should just wire up as normal

	what i mean is does it take the power from the original wireing loom or doesit need some seperate power as well
gsi-gaz	posted on 5th Jan 04 at 11:19
	obviously they need power every head unit does some of them do require a seperate earth
