Question about Alpine MRD-M1000 Car Audio Amplifier
I have a 2 ohm sub and a 4 ohm sub and a 1 ohm amp how do i hook it up to get the lowest load with out dropping under 1 ohm right now i have them wired positive to negative and back to the amp its loud but i dont know the ohm load like this
Are they single voice coil or double?

Wiring subwoofers with different coil resistance is problematic. If they share the same airspace, plan on buying one or more subs in the near future. Because as they share the same power source, having more or less resistance changes the amount of power the subwoofer "sees" in the circuit.
As for your current installation:
if wired in series...
+ on sub (1) to amplifier +
- on same sub (1) to + on sub (2)
- on sub (2) to amplifier
Would result in a Net 6 ohm load
if wired Parallel....
+ on both subs to + on amplifier
- on both subs to - on amplifier
Would result in a net 3 ohm Load.
(The amplifier with higher resistance getting more power however)
Look into getting a matched pair of speakers. While it does not need to be the same manufacturer necessarily, the voicecoils should be identical for both to play at the same level.
No doubt you are experiencing sonic cancellation and musical muddiness when listneng to your current configuration.
