a great high powered mid priced amp giving up to 600W total output I doubt there are any standard cars that this will not have enough power for.
I connected this up to 4x Auna CS LED69 • 3 Way Coaxial Speakers using Transparent Loudspeaker Cable 2 x 2.5 mm² as the speaker cable supplied I considered to be to small and one Auna C8 Double 10" Subwoofer 2000 Watt using the same 2.5mm speaker cable.
On first connecting them all up I could not find out what size fuse for the incoming pos line (I used 8 gauge for both pos and ground taking them both back to the battery connectors no trying to get a decent ground conection via the car body)
but a quick email to Auna Service Department where they quickly informed me that it should be 40W fuse.
The next problem I came across was that I could not get enough output from the sub and on contacting the the service department again they replied that they do not have that information and if it was faulty I could return it for a refund but on searching the internet I came across a usa site that had a great guide which is here (if Auna will print it):- https://www.crutchfield.com/S-JBl63QQ3PeM/learn/car/subwoofers/tuning.html
it is an easy guide to work to.
In the end I am very pleased with the whole setup well worth the money.

Eine sehr ansehliche Endstufe mit tollem Design und guter Leistung und zu einem spitzen Preis einfach klasse. Respekt!
