BOSE low level ?

[Tomson]

Hi All,

Like many I am a little underwhelmed by the bass in the S8.

Hence my decision to add a sub and amp.

Install looks fairly simple (the battery location really helps) but I have a question regrading line converters.

Having read various threads online there seems to be a discussion about whether I need to use a line converter or not?

I suppose the question is whether the signal to the Bose sub is low level already, I am tempted just to adapt some RCA's and splice them into the sub speaker cables rather than using a converter. I am concerned that if they are already low level inputs the converter would just add more unnecessary lowering of the input.

Also if I go down this route, could someone please clarify the wiring from the speaker cable into the RCA. Every guide I see online uses both speaker cables to a single RCA (Sheild negative, centre positive etc.), where as I need both RCA into the amp. Do i just ground the shields from each RCS to avoid noise interference?

Thanks in advance.

Tom
