[QUOTE="PKFiero, post: 8784678, member: 685571"] Hello all! Newbie here.... Hoping I can get some clarification on a planned 'upgrade' of my sound system for an 86 Fiero (yes, you read that correctly!!! Lol). I have a Stock Monsoon Head unit and Amp from a donor Pontiac that I'm installing into the Fiero. Now, the Fiero originally has 2 front 4x10 2-way speakers, and 2 rear/side 4x6 2-way speakers (all rated at 4ohms each). Total of 4 speakers, but I'm planning on adding one 8" subwoofer to help give a little more bottom end. The Monsoon is wired as so: From the head unit, the speaker connections go into the Monsoon Amp as inputs (2 front R&L, 2 Rear R&L). Simple enough... The output speakers are then split up internally (built in crossover) and come out as (each with + and - ): Right Front tweeter Left front tweeter Right front mid-range Left front mid-range Right Rear tweeter Left Rear tweeter Right Rear Subwoofer Left Rear Subwoofer For a total of 8 channels. In the donor car, the stock setup was either each separate component or speakers with dual inputs. How can I hook up these 8 channels to my 4 speakers and Subwoofer? My thoughts were I could do it this way: Combine the Right front tweeter and Right Front Midrange together and pass both signals to ONE Right side speaker (since it is two way) directly from the Amp (of course, keeping the polarity correct + to + and - to - ) Same with Left front side.... Then, do the same for the dual rear inputs... right Rear woofer and right rear tweeter..... etc... But what do I do to get the Subwoofer ? My thought was that I needed to get a crossover for each subwoofer output (Right and left) first, then combine it out to the speakers.... So I guess my real question is, can I take two outputs (tweeter and mid-range) and pass them on to one Speaker? I see lots of articles on hooking up 8 speakers to a 4 channel amp, but I want to do the opposite, 4 speakers to 8 channels.... Any help would be appreciated!! Cheers, PK [/QUOTE]
