Running 3 of these with a 320 amp alternator for a 7000 watt RMS system consisting of 5 amps. After 2 years of driving them pretty hard I am just now having to replace one of the batteries. Not too bad in my opinion considering everything else that they are also running. 12K winch, multiple lights, and onboard air compressor.
Used this amp for the sub stage in my Can Am SXS, I needed the compact size to fit in a specific location and it works great and sounds great. I really like that an amp this small in size still comes with a bass knob and set screw style terminals.
Jacket is a little stiff on this wire, it’s not the softer silicone jacket like on a lot of car audio speaker wire. Nonetheless it’s a good quality wire and solders well
