Amp/Sub question

I am looking for some input on adding subs to my system.I just purchased a Tru T4.65 amp at 65 watts x 4 to run my front and rear Focal speakers.My question is,I have a 4 channel Alpine amp that can be bridged to 100w x 2 @ 4ohms and was wondering if this would be an effective and cheap(lol) way to power a pair 10"subs.I am not looking for loudness or super thumping,just trying to direct the lower frequencies away from the rear speakers so I can play my system a little bit louder.

Thanks

I understand that.But is the Alpine enough power to drive two subs and still sound decent even though my mains are only being powered by 65wpc? Everyone I see has massive wattage going to their subs.I don't want to under power the subs and ruin them.But I also don't want a thumping system that my neighbors can hear blocks away :-)

Can anyone recommend subs that don't require alot of power but still sound decent?

Sorry for the confusion.

JL audio dosen't need a lot of power at all. Max on a 10w0 is like 125 watts.

A sub does not need a ton of power to sound good. You can underpower a speaker all day long and it will not damage the sub provided the gain on the amp is set correctly as to keep a clipped signal from going into the sub. Any sub in the proper box can sound decent, good sound is more about the box than it is the sub. Stevdart is bang on with his recommendation at how to use your existing amplifier. If this is only a temporary solution with the amp, buy the proper subs and build the proper box for your system, upgrade to the proper amp later on. Now this means the subs you choose now may work good with the existing amp, but performance should increase with the proper amp down the road.
