[QUOTE="Lasherž, post: 8717345, member: 679555"] The subwoofer is powered meaning the amplifier is built in. You can use high level inputs regardless of the impedance, that only applies if the subwoofer wasn't powered. You also won't need a "high low adapter" aka LOC because there's one built into the basspro. Also with the built-in one you won't need a signal cable since it'll sense the signal instead. You can tap the high level input from anywhere, so long as the speakers you tap actually do produce tones in the low range, like 40hz clearly, otherwise you're wasting your time tapping them. I suggest using test tones and the fader to make sure of that before you do any disassembling. You don't need resistors in the sub circuit and you don't need to trick your bose system. It's perfectly happy not being connected to a speaker. If you're not going to use the subwoofer and the frequencies that the bose sub produce is acceptable to you, then I see no reason not to tap the subwoofer for the high level inputs for the basspro. It can handle up to 20V signal in its high level input ports according to Crutchfield. [URL unfurl="true"]https://www.crutchfield.com/S-2uFwng4Jo9I/p_109BASPRO2/JBL-BassPro-SL-2.html[/URL] The subwoofer you're replacing would have to be about 200W+ in order for that to be a problem and it's not likely to even be close to that powerful. Make sure you use adapters whenever possible to maintain the original wires and connectors in your car. [/QUOTE]
