Help W/ Electrical Please

[alexd4488]

Hi,
I have been having some problems with my electrical system and I am open to any suggestions. A couple months ago I put in a Pioneer head unit, and my car worked fine. About a month ago i put two 10" subs in w/ a 500W Max amplifier and the lights started to dim along with the beat. I then installed a Tsunami 1.2 farad cap, and the problem is still a problem. I have a feeling i need a hi-amp alternator, but that is the reason I bought the cap, to avoid a new alternator. I am open to any suggestions to try and fix this problem.
Thanks!

I'm no expert on stereo systems but I would install a second battery with an isolator immeadiatly before the positive post.

A high amp alternator will help some with a single battery but the ideal is a second battery with a big alternator.

I am a proffesional car audio installer, and believe me.....a second battery will only worsen your problem. A second batter requires more charging power and therfore will definetly need a bigger alternator. A capacitor will improve you instantaneous current draw, nut not if there is an existing problem with you charging system. At this point, if the cap didn't help, you're looking at a new alternator or primary battery. NOT a second one. Most likely an alternator. And since you're getting a new alternator, why not upgrade to a higher output one.

Makes sense to me......Now that I think more about it.

Second battery might help for a while till it is drained a bit. Then more problems.

I did say "A high amp alternator will help some with a single battery but the ideal is a second battery with a big alternator."

What is your experience with the second battery instalation??

Thanks for the clarification to the thinking of my tired brain.

What about double checking your grounds? YOu might try running a seperate wire to have a good definate ground. Also, might look into the Optima batterys to handle your system demands and the vehicle demands.

Thanks a lot,
I checked my ground and it turns out that I didn't ground it very well. I regrounded it on a different bolt and that worked out for me.
