third idea.
throw the cap in the bin it's not worth a w**k
go for the first setup just need a bigger amp i guess for the subs
oh and the power cap will be needed if you want to turn that up at all, as being a 1.4 the alternator will not cope running just off a standard battery, make sure you keep the car running if your powering 3 subs, also thats going to be a hell of a weight in your boot, if your interested I am about to put up for sale a single Alpine type X 10" sub powered by a JL Audio G-Max 1200w mono block amp

how will the power cap help? it's just extra load on the alternator
Power caps help because they draw power for the subs before it is needed. They put a constant load on the alternator rather than a varied one. That's why when I play my system loud the head lights pulse with the beat of the music. If you have a power cap you don't get this. Cause when the subs are not active the power cap is reserving power or when they do kick in
