I have a 93" SSE and I ran 4 guage wires it looks professional.... I had 2 problems the seats wouldn't come down. ...... I had my ground on the left side of my trunk on a bar that they grounded out my deck at (I think it'* my deck) well... It was extremely loud. I have 2 12" L7'* in a box tuned to perfection and a Hifonics AMP. My amp keeps getting hot and Im wondering where i should ground it out.... I have 4 Guage wire sooooo any help would be greatly appreciated...

Can you take a picture of where the ground is??

Not to insult you, as I don't know how much you know about audio and electronics, but is the ohm load correct for the amp?

When you say the amp gets hot, does it JUST get hot, or does it get hot enough to shut down?

Also, where are the gain and crossover settings set at?

How many watts is the amp?

Is the amp stable down to 1/2, 1, or 2 ohm?

As far as grounding out the amp, you want to try to find the most solid piece of metal available in the area, then clean any paint or oil off of the surface before you attach it.

With the seats, you said that they wouldn't come down.... if your amp ground is in the trunk, this should not affect the seats, might be a different problem.

One more thing, you said that your amp and deck are grounded out on the same bar... the deck or head unit should be grounded under the dash and the amp in the trunk.

We need a little more info to be able to properly diagnose the problem

I can't take a picture right now my buddy has my camera.
i dont know if the ohm load is corrent for the amp and no offesne taken
it gets hot but it doesn't shut off. it gets hot enough to where i can't tough the top for more than a second
i dont know what tehy are set at my amp is in my garage
1200 watts
its a
Crunch Powerzone PZI 325.2
1200W 1 / 2-Channel A/B Class Amplifier
300W x 2-Ch @ 4-Ohms or
600W x 2-Ch @ 2-Ohms or
1200W x 1-Ch @ 4-Ohms Dynamic Music Watts

im not much of an amp guy.... i do installs ill take pictures of my stuff as soon as i get a camera back. thank you for heliping me and not making me feel like an idiot =) I think ill enjoy this website

I would recommend not grounding to the seat bolt. They usually get pretty rust.

Anywhere into the floorpan should be fine. Just check for clearances under the car.

where is you amp mounted and in what orientation?

I ground to the wheel well metal where it is bent inwards in the trunk. So both sides of where the screw are is visiable and you know you wont puncture anything.

It doesn't matter where you ground your amplifier as long as its metal thats attached to the rest of the body and the ground wire is secure (no movement).
Also the ground should be within 4 feet of the amplifer and the ground wire should be the same size as the power wire or bigger.
The ground point needs be rust and paint free.
You can achive this with a grind stone in a drill or dremel and a wire wheel to finish the job or use some sand paper.
If you have a bad ground that would make your amplifer cook. It could also be the way you have your subs wired to the amp.
How do you have the L7'* wired ? They are DVC (dual voice coil) correct ?
In Parallel or in Series ?

Good luck,

There are spots on the bonneville unibody that are better than others due to the way some panels are laminated/glued together vs welding.

Thats true I usually check my ground point with a multimetre set on Ohms or Continuity. I put one lead on a good ground and the other on my planned ground point just to double check. A good ground should have 2 Ohms or less of resistance.
As a general rule of thumb the floor or the strut towers are usually grounded well and are suitable for grounds for amplifers. Typically I try to stay higher up on a brace or something that doesn't get wet, to prevent rusting.

For me and grounding, it all depends what vehicle I'm in and where I'm mounting everything at. For my Bonneville, I will probably ground both amps at the floor or to the strut towers.

In other vehicles I have done, I mainly do it to the floorpan. Sometimes I will do it to the rear deck supporting braces, if the floor just doesn't seem to want to work for me.

Wherever you do, be sure to check your clearances!
