Hello and sorry . had a proplem. soo so I have a mondeo mk1 flowheck. and would like to use there 3 30cm speakers. 2-ciare with 300 watts and 1-rcf with 300rms and 600 max. also 2 ring radiators(hightoner) of ciare and to close two 8″ three away speakers of JBL . hope that it is enough to hear something.(lol) I have to encapsulate the jbl (sepperaten housing) or make it out to him the nix. Not sure if the three 30s produce such a high bottom pressure that it STARK an Then the question as to how I best support the deposit. Because 1 30s weighs as much as 8-10kg. plus the rest of LS. should just support it so that I don’t mind if I want to do something in the trunk.
