Sorry if this has been mentioned a bunch of times - I searched around for a bit but never found a simple diagram regarding.

Just like the title, id like to add a sub to my 4th gen max with the bose system.

I was just wondering how can I get a sub in without doing a major overhaul.

Thanks!

Phil

think of it this way... those cables runnin from behind the head unit all the way back to the speakers (gray with a pink stripe, gray with blue stripe, whatever they are, I don't remember) are essentially RCA cables. Open em up, and you'll see 2 wires (pos and neg) and then some wire ground shielding. Those "RCA"s go to the speakers, which have cute little amps built into em sittin underneath the speakers. If you want a quick easy cheap (and technically wrong, but it'll work) way to add a sub, then splice into the RCAs and put some RCA ends on it and use that as the input of your sub amp. Just make sure it's got a low pass filter to keep all the high freq out of your subs. OR, go to the actual speaker leads (post baby-amp, the ones that actually connect to the speaker terminals) and tap into those and put those into a SLOC (signal line output converter) which will essentially drop the voltage to a RCA input which will then go to your input rca on the amp. A benefit there is that, depending on the sloc you buy, you can have options such as a gain control or built in crossover.

REALLY though, technically, if you want to get all professional, there is no perfectly happy way to interface with those stupid bose systems, and you should replace it all in one swoop... but I can understand why that's not always an option. If I were you though, I'd do an SLOC.

hope that helped.

 

Splicing the rca's and connected rca' ends IS the right way. The signal coming from the Bose is a LOW lever signal, thats why it's done. LOCS are useless in bose setups.

 

Thanks, sounds simple enough. Most amps have low freq crossovers so I should be able to splice the original ones and go.

Sounds easy enough - too bad its negative 1000000 degrees here or i'd go and it now!

Thanks

 

Will this same technique work for a 5th gen i35 with Bose?

I have an amp/woofer setup somehow (don't remember how off the top of my head) but with the speaker saver function (turns bass down when volume is turned up) the woofer is nearly off when the volume is near max, and almost too loud when the volume is very soft.

Is it possible to bypass this function? or is it built into the HU?
