Soundqubed

[Stylesinc2309]

I have 3 soundqubed hdx3 18" dual 2ohm. I am running 1 soundqubed mono 1ohm stable 4500.1 on the subwoofers. Alternator will be upgraded along with adding 2 xs d3400 batteries. Not really going for an spl build. Box will be at least 21cu ft. Wanted some feed back if it would be better to invert the subwoofers or mount them regularly also wanted advice on a port for this box.

I would mount them regular if you could. You'd be good off with just a big slot or rectangular port depending on the vehicle and how it all has to be oriented.

Pretty vague on the vehicle or space, inverted is your choice. I've found thru testing it can affect output. Its a show your magnets thing imo... not cooling. 3-18s is a big mamajama, my thinking is it should be 16.5ft3 net minimum or so /w/300in2 of port. I'm talking about 25ft3 external /w/ single ply 3/4" double baffled braced heavily. Inverted or normal mount is 6/5 and pick em' im my exp

Thanks buck for your feedback. Its going in a 2004 yukon denali...def will probably have them mounted regular firing up. Do you have any ideas on the port.
