You've got a serious amp stack or a high-draw power system and the thin gauge cable you've been running is bottlenecking everything. Voltage sag under load, warm cables, underpowered output — it all traces back to undersized wiring. This is 0 gauge OFC (oxygen-free copper) in red PVC insulation, sold as a 25-metre roll. Run it from your battery to your distribution block, then step down to 2GA, 4GA or 8GA for the final runs to your amplifiers or power equipment. Twenty-five metres gives you plenty of slack for under-dash routing, engine-bay feeds, or a full van build without hunting for a second roll
