I have a Arc Audio 5 channel amp that is very strong with lots of power to push any system. I was running 1 10” DD Audio Dual voice coil sub in custom box. Along with 4 Focal component sets for my mods and highs. I pushed all that with this amp. It’s used with lots of power to give. If you know your car audio then you should know this amp is not cheap when bought new. I paid over $700 for it, but I’m selling it for $550 or best offer.
