You have not set it to the factory spec, and its probably 180 degrees off. Rotate the crank to top dead center (the mark on the crank toothed pulley, align the cam timing marks, refit the belt THEN release the tensioner. Rotate the engine manually to verify that all the timing marks realign themselves.
The spec of your computer should be able to take Win 7 without the hassle of trying to find a "Legacy BIOS" the only way to find one of those is to find an older motherboard of the same spec and use the BIOS chip from there. Or Flash your BIOS with an older image.
You need to look at your wiring of the speakers and the Ohm rating on your speakers.
Below are the specs of the amp. You have the Tri-Way amp and the switch that controls
which way it configures it's output is critical. If you are powering just 2 speakers you set the
the Tri-Way to bridge only. Problem is, I cant find a manual. Legacy's site (
Manual Coming Soon.I say call them and ask for a manual to be emailed to you or mailed.

The o2 sensor will look like a spark plug on your exhaust. it is going to atleast need one.. They are torqued to spec you can find that out from the dealer.. but they have a switch on them you just unplug use an wrench take that one out and then put the new one in.. Make sure it is torqued to spec.
Hi Justin, Send me the specs. on the speaker ( voice coil impedance), amp, power wire size, and box As for engine noise ( alternator whine) 99.9 times out of a hundred it's caused by what's called a ground loop, That will take a little trouble shooting on your part. It's no big deal. It will be a step by step process. All you need is two alligator clips or a old RCA cable.and a couple feet of wire. I'll try to get to it this evening, Oh, and you will have to pull the head unit out of the dash... P
This amp will not give you 1000 watts of real power. From the specs I've found, it can produce 55w RMS x 4. Bridged, that would be 110w RMS x 2. The most you could get into a dual voice coil woofer would be ~220w RMS.
hi there. yes it should work providing you have the correct wiring it for it, if you buy the LV 416 enquire about a wiring kit to fit, most will. theyre normally around 20pounds. most amps will be compatible with most subs. i run both my 12inch 1000w off one 1200amp at half power, they kick lovely and i have no problems.
