Hello everybody. im having a lil' problem with my audio electric system. i have a 3000 watts power acoustik mono block amp with 2 12 kickers L5 with a 10 farad tsunami capacitator and the lights still dim. at first i thought it was the battery that wasnt powerful enuogh so i upgraded to optima dry cell yellow top, but the lights still dim. Anyone has any suggestions?
Thanx everybody.

What alternator are you running? Chances are the stock one cannot power all that it is only 80 amps.

yeah, i still have the stock alternator.
I guess that could be the problem.

^ I bet with a little research you could find a cheap and easy solution for a much better direct replacement alternator but to be a nice guy here is the link

depending how you want to do this..
alternator is a good way.. that is a lot of watts

also

you can try ground your battery better. put 1 or 2 i guess 0-4 gauge wires.. and ground that. try to keep them short. maybe a foot or less.
that helped my civic..
(civics only have a skimpy ground wire..)
solara's ground wire is decent

Just remember if you replace the stock gnds run new wires to the stock ground points or bad things can happen.

solara1989 - I edited your title to provide a description and so it didn't just say "HELP!!!"

by **Eye8Pussies** » Mon Feb 16, 2009 9:23 pm

as mentioned- a good ground, but more importantly, a higher output alternator

OR run a couple more batteries

Here is a cheaper alternative.
I actually running this one as my second battery.
I'm in the process on getting a second one or the bigger one.

consider getting a battery isolator too only one battery dies and you're not stuck.

my vote is for the alternator ! have you upgraded the cables portion from the alt to the battery + ground?

doesnt the sienna have a stronger alternator? You could try a swap

I think the Highlander or rav4 alternator puts out about 150 and its a direct fit. DONT quote me on this one. I've read it somewhere before but dont know where

I think this is the correct one and the solara alternator can be used as the core. I believe it nets you about 50 amps over stock.
