Bose to Alpine amp help


Patch

Recommended Posts

Brideged mode? Low pass mode? No RCA's also.

 

If you tap into the rear speakers and use the high level inputs then on the amp you will need to set the crossover filter for sub frequencies. Depends on the amp but there should be a off/low/high filter switch along with a gain and freq dial .

ps. If using high level inputs I think you need to take the feed from the headunit and not at the speaker if using bose as the bose amp has its own filters and would of already filtered out the bass by the time the signal gets to the rear speakers.

Found this pic of somebody in the US who upgraded their system and retained the Bose HU

It mentions an item called a AudioLink PD-4.

Dunno if this is helpful, but if you intend to upgrade the HU to an aftermarket one in the future, then personally I would wait until then and upgrade the whole system, speakers and amps included, start from a clean sheet so to speak ;)

Patch, after reading through the thread again, if you really have no clue how to do this, then I would personally go to a car audio specialist and tell them to do it.

Especially when power cables are involved, since you will have to run a fused 0 gauge to the mono amp for your aftermarket sub.

Don't wanna risk a fire ;)

Ah, ok then :)

 

Well, if it was myself, then yeah, the link to that speaker wire to RCA box thing looks like a good start.

Since you are hooking up to a mono amp, then I would tap a positive from the right channel and a negative from the left channel, or vice versa to retain a mono quality to the sound was some songs do like a sweep from channel to channel and you don't want to loose the constant bass like it would happen if you only tapped into one speaker only.

as for the remote amp switch wire, I do think the Bose Amp also uses a blue/white wire for this, but i'd have to double check and then you could tap into that for the signal.

Looking at it now, it seems pretty straight forward.
