I have a noveX sub 800watt and amp 1000watt max, although the problem is I got it off a friend and it didn't come with a manual and I don't know what I'm doing I have a friend helping me that knows a little but would be great if I can have any tips please with wiring etc an where they go, along with will it go into my standard stereo

Get some pics up of what you want help with?

Live wire from battery will go through the car to + on the amp make sure the inline fuse isn't in place until everything's wired up.

RCA leads from stereo to amp

Switchable live from the stereo (will be antenna normally blue wire) will go to amp

Negative wire from the amp needs to be as short as poss and mount to a clean paint free chassis point (bolt in the boot somewhere)
