When I listen to anything that would be considered 'urban' music, I go for the low, long notes. Yeah, triple 6 is sometimes on the list. Or alot of the time I will play old booty shake stuff like Uncle Al, Dynamixx, or 95 South.
By the big three, you mean alternator/batts and caps?
Right now I have about 12 foot of 4 or 2 ga running to the the cap, same size running about 2' to the PDB, then 8ga running about 2' to one amp, about 6" to the other. Groud is the same 8 ga to a ground PDB then the 4 or 2 ga to large surface of bare body on at one of the cab mount bolts.
Considering how dim my lights go, Im thinkin I probably have enough supply cable. The factory alternator is already 170-190A, and its because of the towing pack. Other than that, nothing really loading the charge system down other than the engines ECU, A/C and fuel pump. It doesnt even have an electric fan.
Think one or two extra batts will help out with the demand for these 2-3 second long notes?
Caps will do nothing for long notes, they do not affect the voltage while charging since they simply prolong the current demand:
So when the bass hits
- capacitor will maintain the voltage for a fraction of a second
- the battery or alternator will supply the extra current until the amp doesnt need it
- once the amp no longer demands the extray current the capacitor will recharge itself to whatever the current voltage is and will rise as the alternator raises the voltage back to 13.x.
since the capacitor never demands a higher voltage than is currently available it does not add a load to the circuit!
