hdrox88 Posted July 29, 2009 Report Share Posted July 29, 2009 It will help, but cant say just how much. SAZ-1500D on the way? Better get second battery and upgrade the one under the hood. Quote Link to comment Share on other sites More sharing options...

Dr. Johnson Posted July 30, 2009 Report Share Posted July 30, 2009 I would guess you will see a significant difference with a properly installed big three. All three of my vehicles had almost 2 volt differences when they were completed. But I am not sure that this is a normal occurrence. Quote Link to comment Share on other sites More sharing options...

I just did mine today and saw NO difference in voltage, I was very sad.

jl10w3s Posted July 30, 2009 Report Share Posted July 30, 2009 I did my big 3 in 1/0 gauge about a month ago and haven't noticed a huge difference.. I think its cause i have a cheap-o batt. and that my HO alternator isn't putting out its potential cause the computer is regulating it... Time for a MLA Voltage Module.. and I want to upgrade to a Kinetik 2400.. that outta do the trick.. and i also think my alternator belt might be slippin on occasion. only runnin two kenwood amps to two 10's and 4 fullranges. about 1300 watts rms and have 1 run of 1/0 gauge ran as well as the big 3 and the 200 amp alternator(high output at idle) and a 300 amp Soundstream Capcell.. When im at a stop light at idle and bumpin its usually down to 12.5 volts.. Not too happy about that. But i think im in need of that stuff i mentioned before and it should be all good. Im confused why my lights still dim and shit when i have all my shit done right for that kind of wattage if not overkill.. if anyone has any ideas why its not holding a good charge lets hear it..

DGold Posted July 30, 2009 Report Share Posted July 30, 2009 (edited) Not trying to thread jack but didn't want to make a new thread for a related question. My wire from alternator to battery positive is 8 gauge stock. Would that be good enough for around 2k rms set up or should i just 1/0 it and never have to worry about it again? Right now I don't have the budget to buy things that are not completely necessary but I refuse to half ass anything since I love my SUV and system, and would like them to love me back.
