    Icon9 12" Alpine Type R's cut out

    I recently purchased two 12" Alpine Type R's (SWR-1222D) subs and an 1100 watt RMS amp (Alpine MRX-M110). I have them wired for a 2 ohm load i believe. I can only turn my amp gain to about 1/8 turn up and my subs will cut out at 18 volume. I know these subs can handle more than that and I don't know what to do. Maybe my wiring is for a 4 ohm load? Help

    take a picture of how you have them wired. If you don't know exactly how you have them wired, you need to.



    That is how you should have those subs wired.

    I checked and that's exactly how they're wired. So I'm assuming I have them wired correctly. I was trying to set my gains and before I even hear distortion my subs cut out. That's on 3/4 volume and about 2/5 turn up on gain.

    Do you have a DMM? Also what are your head unit settings at?

    Digital Multi-Meter. Measures DC/AC voltage and Ohms.

    What head unit do you have?

    Does that have a seperate sub control? If so, what is its setting?

    Re: 12" Alpine Type R's cut out

    Ok well I was thinking pre-out was low but 2.5 volts should be ok. And seperate sub setting helps with tuning. When your subs cut out does your amp turn off?

    Re: 12" Alpine Type R's cut out

    Sounds like either low imp protection, or thermal protection to me.
    Those alpines amps dont like lower imp that recommended.

    Re: 12" Alpine Type R's cut out

    Sounds like its possible there's a bad connection either your power or ground wire to the amp causing the amp to go protect due to being starved for power under heavy load. Check all connections be sure there's no paint on any metal surfaces and that all connections are tight.
