Electrics On Gem playing up!

[Xplosv Senator]

hi everyone love the site

I need help baddddd my gemini is playing up, it all started with this stupid little amp. The previous owner of the car had wired up an amp like this - The Power and Remote cable connected together to the radio fuse in the fusebox (near the drivers feet) with a piece of wire. The ground was connected to the piece of metal near the fuse box.

The problem was when i went over bumps the head Units volume would mute, i'd have to press the volume button to get it goin again. I got realy annoyed with this so i decided to rewire the whole thing.

So i went to JB HiFi and bought some power cable and speaker wire. I ran the power cable straight to the + terminal of the battery from the amp, then connected the remote cable to the ACC wire of the deck and lastly the ground to a piece of metal. I also replaced all the speaker wire, I am positve i did not remove any other wires apart from the speaker wire and the bodgy wiring from the fuse box.

I AM TERRIABLE SORRY ABOUT THIS LONG POST BUT I REALY NEED SOMEHELP FAST, ALL MY OTHER SOURCES HAVE FAILED AND THIS IS MY LAST RESORT. IF I CANT FIX IT ILL HAVE TO TURN TO AN ELECTRICAN.ONCE AGAIN IM VERY SORRY PPL.

Now this is where the problems begin. My brake warning light cums on reguarly (i checked the brake fluids etc there fine), when i brake the temp gauge goes to high and sumtimes it stays on high by itself (i had a brand new radiator fitted 6months ago and there is water and coolent in it), when my indicators are on the temp gauge goes up and down, at night when i slowly release the clutch or press the brake my head lights dim infact all the lights in the dash and car dim.

So then i removed everything that i had done and removed the Head Unit as well but the problems still persist. These problems were never there when i first got the car (3 weeks ago).

If anyone can help id appreciate it (in fact i beg u) alot once again i am sorry for the long post and i hope i make sense.

THANK YOU IN ADVANCE

My temp guage was hitting the top when i turned the lights on and when i had bass cranking in my car.
Anyways i asked for help and mooch told me to tkae some 3mm or more wire, Put it in to the -ve terminal of the battery and take one bolt of radiator...bare the paint and put the wire into a ring terminal thing around the bolt of the radiator. It gives it a better earth.
I dunno if i said it right but it worked for me.
