Alpine CDA-9815 requires 10awg power?

please tell me this thread is an april fools joke or something.... i find it hard to believe this many people are falling for crutchfield's marketing. if alpine wanted you to run a 10ga power line directly from the battery, do you think they'd have a 16-18ga power line out of the head unit? no.

go to radio (s)hack and buy yourself some primary wire that's at least the same gauge as the yellow line coming out of the head unit and you'll be more than fine.

as for running TWO 10ga lines directly to the battery.... go nuts if you like spending lots of cash and making more work for yourself. if you look on the aforementioned yellow wire, you'll see a noise choke block that has a 15 or 20a fuse in it. that's certainly nothing that needs a direct run to a battery (when they tell you to go directly to the battery, it's a figure of speech meaning not to tap off of another distributed line). the main reason they tell you to run your own line is that they can't predict what manufacturers are going to have for a stock stereo power line and don't want to assume responsibility for melting your car. run the wire to the positive block on your interior fuse panel and you'll be more than fine.

oh, to qualify my statements, i've had a 9815 for over a year and it's had no problems whatsoever.

of course you CAN use any size cable you like -point is, you're not doing yourself any favors or making your stereo run any better.

all i'm saying is that it's overkill to go any larger than what alpine gives you with their yellow wire. if it required a 10ga power line, why would they give you a 14-16ga one that goes into the back of the head unit? if the stereo did in fact pull enough amperage to need a cable that large, the one they give you would heat up (and probably melt) under normal use. obviously they aren't going to do that -what company sells their product with wires that aren't good enough to run it?

i guess i don't know how to explain it any more... spend as much as you like, just realize places like crutchfield are taking advantage of you.

hi all im going to buy a 9815 in 4 days and dammit after reading all of this damn sh*t do i need a wire straight from the battery to the HU or not,

oh i have a toyota corolla 1997 if someone had a bad luck with this car and HU tell me before i scrap up lots of money!!!

thanks to all!
