Installed this last night... had some trouble locating all the grounding points but I got there in the end. Tested it out this morning and can definitely see differences - the voltage meter doesn't drop anymore no matter how many buttons I press at the same time!
Also noticed a little bit more ummpff down in the bottom gears - could be misconception. Have a shitty tape deck right now so no idea whether radio booms more; and as for lights - no lights during day time
Question:
The LED on the unit is always on, even when the car is off... this will have absolutely no chance of draining the battery yeah? I know this is a dumb question but just to be safe.
Finally, talked to my mate this morning and he explained how it works... the unit is just packed with capacitators which hold voltage from the battery. Whenever there is a dip in the power curve (electrical), the unit will release charge and keep the curve pretty much flat. This explains how everything related to the electrics keeps running high if not "higher" since there is no drop in voltage.
Sorry if I've repeated any information before.
Will post photos of my install on my site later on.
Thanks again Greg
