2 ohm subwoofer upgrade in G20 HK
Hi, I am about to change the stock HK subwoofer in my G20, with Audison APBMW S8-2 model. The installer recommended the 2 ohm which was available, but i saw that Audison recomends the 4 ohm.
My question is, will there be some issues with the amplifier, being requested more power to the subwoofer? The Data sheet from the subwoofer shown 150W rms continuous and 300 w peak power. Thank you |

Well the stock Hk ones are 8 ohms, so 2 ohm ones would be basically trying to pull 4x the power.
Probably a bad idea if you aren't changing the amp. |

alizandru check out my post on upgrading your stock system (note: this is for the HiFi version of the stock system, look on the web site for HK-compatible equivalent) https://g20.bimmerpost.com/forums/sh...67&postcount=4

There will be issues with the Booster when it tries to be stable at 2ohms when it is designed to drive 8ohms. |

also i heard you need to code ASD to OFF as the fake engine sound drives massive amount of bass to the point of risking blowing your sub or amp

Still in the process of purchasing it & getting it installed but I budgeted $3K to get everything done, based on my conversation with the dealer/installer. It will be a much superior system to the HK.

It works well. The bump is not substantial, but the bass is cleaner. Audison recommended the 4 ohm because i was going to use the built in HK amplifier. The 2 ohm setup requierea more power and a amplifier upgrade.
