alright i have 2 alpine Type R 12" subs, they are duul 4ohm voice coils, so i will make each of them 2 ohm subs by bridging the 2 coils in parallel.
now i have 2 subs @ 2 ohms each, i have a 1500D hifonics brutus amp, i can run the amp @ 1 ohm if i hook the subs in parallel right? just making sure, since its my first install. |

Watch the gain when you do that. If I am not mistaken, that amp does 1500wrms @ 1 ohm. Both of those subs together are 1000wrms if they are the '05 versions. |

thats a perfect power for those subs (if '05). my repeated rule of thumb is rms+50%. so 1000watts plus 1/2=1500. like isaac said, set your gains.
(simplified) gain setting
turn gain all the way down on your amp.
set the HU to neutral
turn the HU up 75% or just before it starts to distort
turn the amp gain up till it starts to distort or reproduce unclean bass, then turn it down until it is clean. |
