since i've had my car i know i haven't had the best connections in the world, but with the weather how it has been lately {hot, rainy, extremely humid} and {my father spilling water on the battery while flushing the coolant didn't help either} so i've been noticing some things.....the day after the "water incident" it was raining, and the car wouldn't even start...so i left it, went back out, tried it a few more times, and it eventually started up, and has been ever since. But now i'm noticing a faint whining noise in my radio when accelerating, my gauges {mainly oil, temp, and boost} move to the bass {and i don't have a system} the vent blows harder with a touch of the gas, the lights brighten, and it seems if i really get on the gas then there'* some hesitation when shifting..almost like the car has to take a quick deep breath before the shift...
could all those issues be tied to the poor battery connection?

of course. Connections can have a layer of carosion(sp) between them, and you cant even see it. It could appear like a good connection. whenever you start having power issues alway clean all your connections, and when you reconnect, use some electrical putty. After you do that, if their are still issues, I recomend the following.
wait is the battery in the front of the car?

this is what I did when I had some issues. People do this that have stereo systems, but its a good way to get better current flow on any car to elimanate road noise. in conjunction with cleaning all termanals..
1. get some 4g power wire and connectors.
2. run power wire from the alternator to the possitive termanal(usualy the wire from alt. to (+) is a small gauge wire and can get carroded ends)
3. then run some wire from the engine block to the body (ground) and if you can from the body to the frame, this bypasses any rubber engine mounts or old corroded connections.
3. then make a run from the (-) battery termanl to the body/frame.
this creats a full flow of electricity. It worked for me, it may work for you.

cleaning may fix it but not always.
Take this example. You have many accesories grounded to your block. motor mounts are rubber so a manufacture runs grounding wires(usualy small gauge). (have you ever seen an old connection that looks green on the end, and when you tried to cut the wire back, it was green up into the wire. thats corrotion, and it can ruin a wire, and that connection). So if you have another ground wire its holding twice as much current.
sometimes on older cars(usualy pre 90'*) body panal like fenders and wheel wells get a layer of rust between them. So putting a ground on a fender doesn't nessasaraly mean that you are getting a good connection to the battery which may be grounded to the frame. If the curcuit doesn't get back to the battery (unimpeaded) you have a bad connection. I.E, road noise, dimming of lights.
