The same OCC single-crystal copper core, triple-layer shielding, and high-current design — now available in three conductor cross-sections so you can match the cable to your amplifier's appetite. Whether you're powering a compact integrated amp or a big Class-AB monoblock, there's a gauge that fits.\u003c\/p\u003e\n\u003ch3\u003ePick your gauge\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e13 mm OD \/ 2.5 mm²\u003c\/strong\u003e — the entry point.
