2 amplifiers, as in one amplifier per sub?  If so, you will need to wire each sub's coils in series for 8 ohms, then bridge one to each respective amp.  You should really use just one of this model amplifier for the two subs, and i am an idiot's post shows you how to see the wiring.

Do this on each amp using the "bridged" connections.

You'll have an 8 ohm load on each amp for 150w rms.

it's a matter of power.

With one amp running both subs you'll get around 100w per sub.

With one amp per sub you'll get about 150w per sub.  It's not a huge difference, but IMO every little bit counts.

You did say 'get the better sound'. To me, this would give the best sound, although you'll be using the amps for all they've got. You'll still be giving the subs the same amount of power they would be getting by running one to each amp -because you're still running one sub to each amp, while your door/dash speakers can get more power for cleaner sound.

You could do a dual-amp tri-mode setup. ***The amp MUST be tri-mode or tri-way capable, the door/dash speakers MUST have an impedance of 4ohms or greater, the subs MUST have an impedance of 8ohms or greater, the door/dash speakers MUST have passive high-pass crossovers (@ about 80-100Hz) wired in series with the speaker, and the subs MUST have passive low-pass crossovers (@ same freq. as the door/dash speakers) wired in series with the speaker.

1. Have the front speakers connected to amp a in stereo, with sub a wired to the bridged output.

2. Have the rear speakers connected to amp b in stereo, with sub b wired to the bridged output.
