So I'm been on the web looking at different types of 5k amps that are linkable amps, so I can upgrade my current amp set up...I'm looking for a amp out of these new or used- dd m4a, sundown audio 4500, crescendo bc5500, dc audio 5k, ampere audio 5000.1. It has to be able to do around 3800-4000 wire down to 1.3ohms. Running 3-18s DSS ethos box is in the works.... Electrical is dual alts stock will run the truck, mid, and highs the singer 270amp will run only for the battery bank. 4 juice box blackcherry battery back, two runs of 1/0 wielding wire. ( would like more batts if space would allow) ( playing music daily and burbs on comps) I'm not looking for a father and son conversation here just wanting to know which amp would be better suited for my set up that's all thanks for reading.
