I'm curious to find out that if one was to replace the active bass response alpine OEM system in a 92 190E, with the newer alpine units, would the amps in the trunk dirving the subs in the door still be operational ? or would I have to bypass them ?
More over given the stock is two channel, and that's how the door subs are setup with, how would i hook it up to the four channel output of the new units ?
