adding second amp

  E87 118i

how can this be easily done, do you have to have 2 x pre-outs on the HU, or does the 2nd amp connect to the first somehow ? I did a search and someone mentioned something about a splitter or something....

....or do I just try and sell my 2 ch amp an buy a 4ch one ??

....will a 2nd amp affect the battery ?


i used an rca splitter for the pre-outs got it from maplins and for the power i used a bigger power cable ran it through a power cap and split it off to the amps.

It will affect the battery to solve this uprate the battery and alternator.
