I'm assuming that you have an amp that you are installing these to. Its always tricky installing subs of different impedances. Do you have the model number of the amp that you are hooking them up to.
Most likely if you have a 2 channel amp, you would connect one sub to each channel as most amps can handle a 2ohm load in stereo, but don't bridge the amp with these two subwoofers without specific instruction from someone with experience as you will most likely overlad the amp. If you can be more specific with your set-up I'd be able to assist you more.

I have the Alpine MRP-M1000 amp. I want to use 2 subs with this amp. Which Alpine subs would work best with this amp?


this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres
2 - 8 ohm speakers in parallel = 4 omhs
2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers
2 - 1 ohm speakers in series = 2 ohms
2 - 2 ohm speakers in series = 4 ohms

I just picked up a 12" type r in a box with a alpine m 350 how do I know what kind of type R I have without taking it out of the box?? and how do i hook it up to this amp??


Not to insult you in any way but u need to know how to wire into car's electrical system at the battery then to a fuse then to the amp and then output the signal from the deck to the amp.. finally to the subwoofer. you need to hook up 12V constant battery power , then remote from the deck ,ground wire from amp to chasis for power.. then wire to sub.

I just wired my alpine type 12 4 ohm subwoofer to two ohms by putting the two red runners in the positive terminal and the two black runners to the black terminal and hooked the wires up to the outside...


If you have the Alpine SWR-1222D, that's a dual 2 OHM Sub. So, the way you have it hooked up to the amp ,it's 1 Ohm, and unless your amp can safely operate at 1 OHM, you are better off connecting the voice coils in series so the amp will see 4 OHMS. The link below will show how the connections are made to the amp. Look at example # 1.

Alpine sub woofer


your speakers are hooked up wrong. hook both positives together and both negatives together and bridge it to the amp. if it is one channel hook it up as one together. if it is 2 channel hook positive to one side and negative to the other side.
