Re: I need to know what ohm level my 1501 d class mtx...
Connecting a single speaker, speaker impednce should be equal to or greater than 1 ohm. Connecting 2 speakers, each speaker's impedance should be equal to or greater than 2 ohm

NEVER mix different power amps. Depending on the ohms of your subs, sell one of the amps, up to you. The 4001 has more power, but either amp will do the job, the amp needs to see a 1 ohm load, so your subs have to be dual 2 ohms, or single 4 ohms to do this. If your subs are dual 4 ohms then you will have to run your amp at 2 ohms which would be have the power, or a half an ohm, (Not Recomended) and be at double the power. You may be able to do a competion sound off and just "Burp" the subs, but at a half an ohm, dont expect to listen to it to long before it goes into protect and shuts down.
To wire up a 2 ohm load depends on the subs. You will either need 1 sub rated at 2 ohms or 2 subs at 4 ohms wired in parallel. This website will help. http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=41#results You can also use 1 dual voice coil sub rated at 4 ohms wiring the same way you would the 2subs at 4 ohms. Good Luck
first of all you should check the minimal impedance your amp handles , if is class d it should handle between 1-2 ohms total impedance in a mono conection , meaning whatever quantity of subs you have hooked to your amplifier,their total impedance should the minimum the amp handles that way all the power from your amplifier will be used.
SINCE YOU NEED A 1 OHM LOAD, I PRESUME BRIDGED AND ARE USING TWO SUBS, THEN HOPEFULLY YOU HAVE THE DUAL VOICE COIL TYPE, AS THEY ARE DUAL 4 OHM AND YOU WILL HAVE TO CONNECT THE VOICE-COILS IN PARALLEL WHICH WILL MAKE EACH SPEAKER A 2 OHM SPEAKER AND THEN CONNECT THE TWO SPEAKERS THEMSELVES IN PARALLEL AND THIS WILL PROVIDE YOU THE 1 OHM LOAD. IF YOU IN FACT HAVE THE SINGLE 4 OHM VOICE COIL VERSION, THEN IT WILL ONLY PARALLEL THE PAIR DOWN TO 2 OHMS. OK. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
I ASSUME YOU HAVE THE TC4002:
100 WATTS X2 @ 4 OHMS.
200 WATTS X2 @ 2 OHMS
400 WATTS X1 @ 4 OHMS BRIDGED.
LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V
Your MTX 7801 is stable at 1 ohm, but you cannot wire a pair of DVC 2 ohm subs to that impedance. They can only be wired to 1/2 ohm which is too low or to 2 ohms.
Series the voice coils and parallel the subs. On each sub, jumper Black to Red/White Dot, then run both red's (positive) and both black/white dot's (negative) to your amp terminals.
