1- Will change over to yellow top battery.
2- will put in a power cap
3-will put in a wiring kit like this one:
Car Audio Direct - The UK's leading car audio and stereo resource.
However, gains from using this have been reported at only +5% of altenator capacity, giving me +5amps if im lucky. |
Euhh...getting more current from different cable? Don't know where that current might come from. Current is - according to Ohm's law - specified by voltage and load:
Voltage = Load x Current, or U = R.I
In perspective of this: When your cable and connections are only 0,05 ohms all together, when drawing 80 amps, you loose 80 x 0,05 = 4 volts. So your amps will get 8 volts instead of 12... The other 4 volts are used to warm up the cables. Cruel, isn't it?

4- Altenator - honda have said it would invalidate the warranty to put in any 3rd party altenator, and i dont even know if one with higher capacity exists. If anyone does, please do let me know? Altenator at full load, without an aftermarket audio system runs at 75Amps (Honda said) leaving only 20 amps spare capacity.
5-external power - is it possible to run the car audio system on external power WHILE DRIVING? If so is there a smallish, rechargeable solution available?

Yes, that is called an accumulator (accu) or BATTERY.
Seriously, you can allways add an extra, pre-loaded battery. But since you will not use the full power of the car stereo 90% of the time (for your ears sake) You can also choose to add an intelligent charger circuit and install the extra battery permanently. These intelligent chargers quite common in solar power applications.
