right now i have a type-r (2ohm+2ohm)(only about one month old)wired a 1ohm into a hifonics BX1205 and i like it, but i have some spare cash so i want to upgrade. i am in the process of buliding a dual box and already have everthing i need. should i buy another of the same sub (1222d) and wire it at 2ohms(rated 900watts rms) or sell that sub and get a package deal for a pair of Type-r (1242D) so i can wire them at 1ohm (rated 1200watt rms) and what would the prices be aproximatly (with good warranty) thanks
