SOURCE: alpine amp and subs questions
it will depend on how you use the 2 alpine subs,, do you know what there individual impedance is [ ohms ] and how you intend on wiring them,,,in series, in parallel, in any case you must maintain the min load in order to load the amplifier properly,,,otherwise the amplifier will operate improperly and allow DC [ direct current ] to pass and fry your subs...so what I really need is more in formation

SOURCE: installing two amps
No, thats what you don't what to do. Even if you have 2 matching amps you don't do that. Every amp puts out different, and for 2 subs, you want to play at the the same time. If your only running 2 10's, I personal would just run the alpine (it's a mono amp made especially for subs) thats plenty for what you have. make sure you bridge them to get the full response. And your other amp i would use for your highs or mids, but run it @ stereo , which is 300 w @ 4 ohms. (Note: 600w @ 2ohms would be bridged and would play in Mono)
Building Competition stereo's is a big hobby of mine.
