not true. you need the wiring loom.1. I always thought that a Bose upgrade was a simple matter, Plug & play ..... is this true or not?
not exactly sure if the 156 Bose system is any different to the one in the 147/GT, except the shape of the sub enclosure.2. as well as the
* 6 door speakers [ 4 large, 2 tweeters ]
* 1 sub woofer
* 1 amp [ with approx 20 wires going ito it ]
* 1 rear parcel shelf
if you have a non-Bose car & you want to upgrade do you need the wiring loom from a donor Bose car
unsure actually. but it starts with different wiring into the headunit, powerwiring to feed the amp, audio signal wires from the headunit to the amp, and speakerwires from the amp to all speakers/sub.3. if you do need the wiring loom...... what section do you actually require.
not sure about this either, except what it's 'worth' and what someone is willing 'to pay', can be quite disparate.4.what value is an Entire working Bose system worth?
there are no "tweaters" in the BOSE system, the "bose" emblems are just space savers (if you take them off you'll find nothing behind them ... the front and rear speakers are identical and are just a single speaker ...
... oh and don't bother it's not really that great ... you'll get more money selling the parts on the bay ...
Well that's different to mine and some of the other guys on here ... the bose amp does not have the outputs to drive 6 speakers (plus the sub) ... one of the other guys on here (from austrialia ... can't remeber his name) had BOSE plastered all over his 156 GTA but upon investigation found that it was missing ...the door speakers had a seperate tweeter on top of the bass speaker.... & yes the upper teeter with Bose wrote on it had a little speaker in it with a wire connected into it.
Did you take the entire door card off to look at that or take speaker grill off the tweeter? reason I ask is because the wire does plug into a pseudo speaker (probably so the wire doesn't flap around ...)the door speakers had a seperate tweeter on top of the bass speaker.... & yes the upper teeter with Bose wrote on it had a little speaker in it with a wire connected into it.
Wasn't sure on the 156 but looks like you guys get tweeters as well then , just not the center front one.Here's a description of the BOSE system for the 156 (from BOSE) http://www.bose.eu/EU/en/Images/Alfa 156_EN_tcm42-6156.pdf
