Hello noise affinity among the FTCustomizers, I have now opened my own topic, because I now want to go to action and in a first step to renovate the bass area of the FTCustom. Underhttp://www.motor-talk.de/…/…ow-adaptor-enhanced-t5227602.html?… (like in the middle) I had already expressed some thoughts on the topic. Now I have made nails with heads & ordered the 4+1 – final stage “Alpine PDR-V75”. It supplies the original Lsp front and rear and the bassbo The subwoofer “JL Audio CP110LG-TW1” is purchased. It fits under one of the two seat benches at the back. If everything is installed, I will continue to look & if necessary take care of the replacement of the original Lsp. Finally, a question: Has someone ever lowered the passenger seat from the console? I want to place the power stage there and it always hits somewhere when pushing forward or back, so that you don’t get it. MffG
