[QUOTE="IrishChamp, post: 6225147, member: 602588"] thanks for your help. I will change the design to port on the passenger side with both subs next to each other right below the port on the passenger side. why do you suggest 35hz vs 30? how will that effect the sound quality and output characteristics? Sundown's website says that ported to 30hz in .6 cu^f each it will have a F3 of 25hz which means that it will have a noticeable drop off in output at 25hz correct? My last sub was a single Polk SR124DVC being powered with 800 RMS watts in a 1.2 cu^f sealed box that played flat to 20hz from what the white paper said. now that was in a MUCH bigger car coming out of the trunk so I know this is a different game now but I really don't know what to expect from this setup and building a ported box. thanks again. EDIT: also wanted to clarify if box area should be 1.2 before or after subtracting port area, braces, woofers etc, not sure if the programs out there do that automatically. [/QUOTE]
