use for a ground
 
2000 bonneville ssei what to use for a ground? hooking up an amp and subs

i believe a very common, and reliable method is to connect it right to the bolt that holds your back seat to the frame. its sure to work, and keeps the ground cable short because its close to the amp, assuming you're going to put the subs in the trunk...

Would that be the same for a 94 SSEi?

actually, its a surefire way in any vehicle. the ground wire is simply supposed to, in some way, be connected right to the frame, or any part of the car that will go back to the negative terminal on the battery. thats why when you are jump starting a car, hooking the negative clamp to any part the the engine bay that sparks will work! anyway, the seats are bolted directly to the frame, in most cars anyway. so feel free to attach the ground wire to the bolt for your seat.

Cool, I was just thinking it wouldnt work cause I figured thered be paint covering the brackets and all.

i usually connect mine to one of the rear strut bolts.

i tested it as a ground with teh volt meter and got 12.5 volt so its a good ground

to do this you put the possitive rod ont eh pos bat post and then take the neg and place it where ever you want to put your ground for the amp and as long as it read 12.5 or higher you have a good ground.

th lower the number that shows up the less power you amps get and if its too low then your amps will not even turn on.

well, if there is paint covering the brackets, then you'll have to sand that off first. but since no one really sees the brackets its probably not that thick of paint. otherwise, jayGXP had a good idea as well. if you have a volt meter then you can pretty much just test wherever you want and if you get a good reading then go for it, otherwise, if you don't have a volt meter, those are two good ideas that pretty much always work.
