Our Ultra-Amp box is essentially our Ultra Deep box (item ctb99-210/212 Ultra) with have the box being a sub enclosure and the other half being an amp shelf. The box fits exactly the same as the dual box and with the seat down, will look identical as well. The volume is customizable too, but note that that amp shelf and enclosure grow and shink in inverse proportion.
