2 subs, different resistance

hi, i accidentally purchased two of the same model speakers, but with different resistance. i bought a CVR10-2 and CVR 10- 4, i am planning to hook them up to a ALPINE MRP-M650 amp. 600W RMS at 2ohm and 400W at 4 single channel, i bielieve both of the subwoofers are dual-voice coil. is it possible to install both of these under the same amp? any help is appreciated, thanks.

It's not the best idea, but yes it is possible.  Wire the DVC 2-ohm in series for a 4-ohm load, and use only one voice coil of the DVC 4-ohm speaker.  Wire these in parallel to your amp for a net 2-ohm load.  The 10-4 might be in danger of overpowering, but as long as you don't crank it continuously you should be OK.  A better solution is to trade it back to your dealer for a second 10-2.

dammit, i was hoping you would not say that. im new to this car audio buisness. i know a bit about electricity, but not much about audio. i have a 99 durango, and decided that the sound system was inadequate. im on a really small budget, bought most of my stuff off of ebay. i just want a good bass, not a system that sets off alarms. in terms of quality, and ease of use/installation would it be worth the extra ~60$?

sorry to ask these newbie questions, but do you think this 600W will be good for my SUV? also, when installing: do i need to use some kind of fuse between the amp & battery like they have in those "sub wiring kits", or any line for that instance?

And make sure you use a fuse equivilent or bigger than the one on the amp you're running power to...

This isn't necessarily true.

The fuse size should be based on the wire size, not the potential current draw of the amplifier.

well, im most likely going to use 8 AWG wire and its going to be quite a lenghty pull, around 20'. would a 40amp fuse do? should the fuse be near the battery, or closer to the amplifyer? thanks for all the help.

8 gauge is fine.  You can fuse anywhere up to 100 amps: https://www.the12volt.com/info/recwirsz.asp.  Use at least a 60 amp fuse: https://www.crutchfield.com/S-SpWVc1Py6tQ/cgi-bin/ProdView.asp?g=120&I=500MRPM650.  Using a lower rated fuse could potentially cause that fuse to blow when you crank it.  Fuse near the battery.  The idea is if the wire shorts, the fuse will blow, and the car will not catch fire.  If you don't fuse near the battery, and the wire shorts to ground before the fuse, there's no protection, and the car can/will catch fire.

My ex once told me I have a perfect face for radio.

i did not get the amplifyer that i intended on installing. do you think the aliping m650 will be good with these two cvr10s (i now have 2x cvr10-2 and one cvr10-4 with no use) or would you recommend a different amp? (withing the limit of 200-300 $)

The alpine will be fine.

Fuse per geepherder's post.
