I have a problem with my car?

[Puppet Master 10+ year member]

I was driving around last night, I live in ND, and it was rather cold out. I had just started my car after coming home from a basketball game and I was gonna drive around. When I did I noticed something a little odd. I have just put in two 12'' 600 watt subs and an 800 watt amp. Everytime I accelerate the lights and the air conditioning/heating "revs up", the lights get brighter and the air blows harder. Everytime I brake air blows less and the lights dim, all the lights I mean. Do I need a new alternator? Could it be my battery? HELP?

your electrical is going to die if you do not upgrade soon. start with a good battery and big three

Sounds like you're drawing too much power, and possibly killed your battery.

New Battery + Big 3 will help.

Is it hard to do that Big 3 thing? How much will the wires and stuff cost?

cost me like 25 bucks to do my big 3, i still have to do the alt to pos but still for the most part it solved my problmo, but when i do that wire it should be fullysolved.I also bought a yellow top with the big 3.

could I just get a new alternator? Would a capacitor do anything(assuming I got a new battery)

anyone?

Your alternator probably isnt bad. You can get a free electrical test at Autozone or Checker.

A capacitor is not a good solution to a weak electrical system. Have the alt checked. Get a new batt, and complete the Big 3 upgrade.

So instead of the Big 3 thing, I could get an alternator, and a battery and call it good?

An alternator and a battery is 2 of three. all you'd need to complete the big three would be to lay some fat cables //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
