Looks like I will be using a Memphis 4kw on each sub for now, hope to go to 2 4kw's each later. Also thinking of 16 volt charging system and several 16 volt batteries. Subs are dual 1 ohm.

Just ordered 2 15" fully loaded BTL's. Wondering what to use for power as this will be mainly a SPL application. Using a wall in a extended cab pickup. Box area for subs will be close to 10.5 cubic feet after ports, subs and bracing are subtracted from total box area.

Any suggestions on what to use. Need ideas. Want to start build for next year as soon as I can.

For a 1990 Chevy ext. cab pickup. I was told this be Michael Jones. Build box as large as can and 165" port area per sub 7"-9" long port for 2 15" DD 9515 subs . If could would rather use 15" Fi BTL's. Area behind seats comes close to 18 cubic feet internal box area. If have a different recomendation for box design I'm willing to listen. Looking at using 2 Memphis 4kw amps and 16 volt charging system.

Will 15" BTL's work in a ported box for DD 9515 subs. Port area is 165" per sub and port is 9" deep. This is what I was told to use for the DD subs. This is a SPL set up only. I know this is more than FI recomends for port area. Total box area is about 17-18 cubic feet.

Thanks for the help.

Will a 18" BTL handle 2 Memphis 4kw for Street Beat or burps. Also when building for SPL only is it better to use a small or large box. Can you also let me know what a recone costs for a BTL a 15" & an 18".

Looking to build new system. Planing on using a Memphis 2500 watt amp to each sub. This system will be mostly for SPL but also some daily listening. Will be using 10" or 12" subs. Just wondering which Fi sub would work best. Will start with 2 subs but move to 3 at a later time and maybe a Memphis Mojo 4kw to each also.
