Stereo wiring

Could any of you pro's give me some advice of how to connect the power wire to the battery? also where is the best grounding point for no interferance. I also need to wire an invertor in?

Any help greatly appreciated.

Thanks

You can, but if your amps are located on the drivers side of the car you wouldn't want to run the ground wire to the other side of the car. You can ground you amps to any grounded metal surface in the car. Just make sure that you sand away the paint so that you get metal to metal.

Depending on how many amps you are planning on installing (now and in the future) depends on how to connect to the battery.

If you are only going to install one amp (in some cases 2 just split the wire in two not recomended) in the car, you can get a a ring and crimp it to a fused 4 gauge wire. and connect it directly to the possitive battery post.

If you plan on installing 2 or more amps I would attach a 1 ga. wire to the battery and run it to a fused distribution block, and run a 4 ga. power wire to each amp from there.

If you are talking about a high to low level converter, the instructions are pretty easy. Left speaker (+ to +) & (- to -) right speaker (+ to +) & (- to -).

Good luck

Gound wires have to be short, but how short is short? (Yes I know as short as possible), but how short is that? Accross the trunk is bad? So maybe each amp should have its own ground? what about a ground dist block?

I assume you're putting the amp in trunk, and if that's the case, there is at least one factory ground block on each side of the car on the fender walls, so regardless, it's not necessary to run the ground to the battery. Also, you want to ground the amp with the other components, so you don't have a ground loop.

Yes, the ground wire should be as short as possible, but that doesn't mean 6", but it also preferable to not run a 3-4' one to the other side of the car.

Regarding connecting to the battery (+), and wiring in general, I find the amp install kits (e.g., Monster), helpful in providing all hardware necessary for a technically sound and clean-looking install.
