Electrical Question

[conn.am 10+ year member]

My battery has been dying alot lately and i took my car to my mechanic today. I tried to explain to him that I was planning on adding some speakers to my car and i would be running two amplifiers (one for my components one for my subwoofers). I told him one is a 2000 watt amp and the other one would be smaller. I explained to him that in my old car my lights would dim whenever the speaker hit. I tried to explain to him that some people upgrade there alternators to help with this problem. I also said i believe there are some kind of "special" battery that people use to help also ( I cant remember what there called....yellow top or something). He told me someone was probably just trying to sell me a battery and that he dont think i need to upgrade my alternator. He did say that adding a second battery should take care of my problems.

Is he correct? For some reason from reading around in this forum (WHICH IS GREAT HELP BTW) I believe i need to upgrade my alternator. Right now i plan to run a hifonics bxi2006d (2000 watts but over-rated) to push two 10'' type r's. I also have a pair of morel tempo 6 6.5 components that are going to need an amp. I also plan to one day upgrade to a Sundown SAZ-3000 (3000 watts underrated) to push some higher quality speakers(Maybe some fi bls).

My question is what all do i need to upgrade to help with power draw. Ive heard of the big 3 upgrade somewhere. Whats that?

The BXi isnt really over rated.

I plan to run 2000 watts (overrated) on two 10 inch type r's.

How will i know if its needed? When my lights stop dimming or what?

If i plan to run a 3000 watt amp will the big 3 be enough?

How I would do it..........

H.O. Alt, Big 3 and brand new battery

Full tilt your system and see if you are dimming. If you are, add an additional battery.

i say battery before alt because a battery is a bit cheaper.

unless your mechanic does car audio too you really shouldn't ask him. 9 outa 10 will blame a car stereo for any type of electrical problem with a car.

First off, would you take your car to the audio shop to get a new ******? take your car to a professional audio shop and have them give you a quote on getting it done right. Yes it will cost you more but if they are a good shop, it will play louder, sound better, and not burn your car down.

To directly answer your question, you will need to tell us what vehicle you are trying to put this in. There is no one-size-fits-all solution for car audio. Every vehicle is different.
