Subs and amp

[Niall]

best place to wire your amp up if you dont want to go from the engine bay is to go from ignition then run it as you would if you had come through the fire wall

i will do a guide for it soon as it is a safer way to do it and take about 15min to do no drill no splicing

Sorry are you saying take the main power supply for your amp from the ignition wiring? If so, this is not a good idea! That wiring is that size for a reason. Because it already supplies a lot of stuff!
