I ordered an amp and a sub for my MCS, how do I wire the amp and sub at 2 ohm?

I have an Alpine MRP-M450 amp and an Alpine SWR-1042D 10" sub.

I attached the pdf files with all the specs... Any info would be great...

I also noticed that the SWR-1022D is 2Ohm-2Ohm, where the SWR-1042D is 4Ohm-4Ohm, should I have gotton the 1022D?

Thanks

 

H/K or standard stereo in your MCS?

 

Its standard,

I will be running RCA's from the head unit by a LOC

I'm just curious how to wire the actual sub properly, thanks.

 

Easy, the sub is dual 4-ohm voice coils so wire the voice coils together + to +, - to - and the amp it hooks up to will then see a 2-ohm load.

The amp is a monoblock so there should only be one set of speaker terminals... hook up a wire to one of the + terminals of the speaker to the same on the amp and do the same for the negative.

Voila, 2-ohm load on your amp.

 

Buddy Lee Thats what i was pretty much thinking...

So it is better that I got a 4 ohm speaker vs a 2 ohm speaker? for this setup?

 

Per the amp specs, this amp gives maximum power @ a 2-ohm load so you made the right speaker selection.

 

Thanks for all your help...

Maybe you can help me with some speaker upgrade selections... I have the basic stereo/HU, and I want to keep it... I know it doesnt put out alot of power, but I am looking for some good mid/ high range speakers to replace at least the front ones... They have to be high efficiency/sensivity +91db, any suggestions?
