Okay guys so I keep getting different answers on this question. I currently have a Y33 Q45 with bose in it. This mean there are no RCA's on the deck or anything like that. Now a lot of stock system come with stock subs, mine does now. I have two mid-bass subs. I know I need to tap into one of those but i'm not sure what converter I need to get. Do I need a hi/lo converter? A line Level converter? Or a Line out converter?

Thanks,
Elliott

 

you need a line out converter and grab signal from the speakersu need to grap it from the speaker wire that goes to the speakers after the amp

 

Even though i'm not taking the signal from an actual subwoofer?

 

Are you wanting to power the subs with an aftermarket amp? If so, you need a line level converter. You will feed the high power line from the OEM amp into the converter, the converter will do its thing and lower it to pre-amp level, then out that goes into your aftermarket amp to power the subs.
