sir that is a beautiful amp..congratulations!! wonderful purchase..
yes ..the w12prs will sound amazing in a 1cuft sealed box (thats what pioneer recommends for this sub)..
and 240rms is more than enough for this sub...its probably one of the most efficient subs. i think its got around 92-93dB sensitivity. u can make it go loud with just 200rms...
i hope u intend on making a sealed box?? cause as far as i remember, pioneer has not recommended this for vented box...its a purely SQ sub..
as for ur amp...well ...my mouth is watering!
good buy!
