Possible Battery problem??

[RobertFielding 10+ year member]

ok well, i am new to all this stuff, i recently just intsalled 2 sony 5 1/4 xplods in the fronts and some sony 6x9 in the back... i had a sony deck paid 120 from Best buy for it... and put it in... well once the volume got to like 20/30 the deck lights would dim and then the deck would shut off and trun back on. so i cahnged the deck to a kenwood from bestbuy.. and the same thing still happens, the lights dim and it shuts off and turns on... now the night i installed the sonys... i had my dome lights on like all night... could this have drained my battery out?? and now i need to recharge it or do i need a new one??/ the deck lights are the only thing that dims though, my Headlamps are fine and so are my interior lights. please help.

When you rev your engine up does the lights come back to regular or stay dim?

For the deck it sounds like a bad ground....My cd player dims when I press a button and I re-done the ground and its fine now.....

Check your deck ground....grind paint off of metal you connect it too...
