To make life easier, get a vehicle specific wiring harness. Watch the prices, they are usually around five bucks ... some local shops may try and sell you one at their 105% mark-up. It plugs into your factory harness, and then wires straight up to your head unit's harness. Plug and play, and a lot easier than cutting your factory harness off.

You will also need a trim ring, or 'installation kit'. Again, fairly cheap ... usually less than ten bucks, so watch the price. This fits around the head unit and fills in the gap.

Hope it helped.

If you run into any problems or have any further questions, don't hesitate to ask.

That's a great head unit you purchased - you should be very pleased with it.

ok i had mine just installed at circuit city... in the crutch field magazine it said i needed a 10 amp gauge wire to run to the battery but the guy at circuit city installed it with whatever it came with???

btw.... optima red or yellow top battery

at circuit city they use harnesses that go from your car specific harness to universal and then another harness that goes from universal to your brand specific (but since its a 9815 theres a special harness for that since its more powerful, but im not sure if it has the 10 guage wire or whatever).

and trentsteel get a yellow top theyre made for sound systems... red tops are made for more cranking power.

I know many people who don't use the 10 gauge wire and are fine ... including me - mind you, I don't use the internal amp. It's no biggie in my opinion, but if you have 5 minutes sometime and want to run 10 gauge, go ahead.

Whats the purpose of the battery and where will it be placed ?

Definitely run the 10 guage wire direct to the battery if you are going to use the internal amp. If not, just use the factory wiring harness.

I had my 9813 (same internal amp) installed by my Alpine dealer. They hooked it up to the "direct battery" wire on the factory harness. It made my SPX components sound like crap. Once I realized what they'd done I asked them to run a wire direct to the battery per instructions. I finally called Alpine and talked to one of their engineers who validated the need for the 10 guage wire.

My installer was blown away by the difference it made. 100% improvement.

If you're running your components off of your head unit still (sorry if I understood you wrong, but thats what I got), try a little amp on them ... then you'll notice a major improvement //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif .

That was an interim solution. I'm in process of installing an MRV-F540. Now I'll run the rears off the deck amp.

Awesome, I'm sure you'll enjoy it.

Don't mean to hijack this thread, but how did your components sound off of the "beefier" internal amp of the 9813 ? Would you call it reasonable to do so until one could purchase an external amp ?

Absolutely. It was a good standby until I got an external amp. Even with these relatively hungry components. At reasonable volumes they sounded great. They did start to distort when it got loud...and the bass definitely needed a little more power. But most friends who listened to them were really impressed even without an amp.

Thanks, the answer I was looking for. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
