Mach Stereo help!!

Welcome to the world of the Mach stereo. You can put a new head unit in but you need a special harness for it. If you want to put in diff. speakers you will need to rewire the whole thing. From what I was told the stock amps use 2 ohm and almost all aftermarket speakers are 4 ohm. If you try and put them in they will sound like crap. So you can just do a head unit but if you want to upgrade the speakers and head unit....you need to spend some $$. I'm not sure what the part # is on the harness for the head unit....someone on here should have it.

No, it's not true. A friend of mine had a nice Pioneer unit put in his '01 with the Mach system. Best Buy put it in. They did have a hard time figuring out the wiring but they got it in there and it works great.

I just installed a flip face head unit in my car. Sounds great. Got all the parts I needed at wal-mart. You need a scosche premium sound stereo harness and then you need a scosche line out converter. I forgot the wiring harness number. The line out converter part number is SLC4. It has a setting on it for factory amp interface. You must use this setting. The speaker signals for the mach stereo go to the first amp as speaker level inputs and then get converted to preamp outputs/inputs for the two rear amps in the decklid. Keep in mind this is for a 98 and somewhere like 01 or something like that they changed the connectors or something... not sure what they changed. Hope this helps

I just installed a kenwoord head unit in my 97.. I could not find the harness that i need to use the amps so I decided to bypass them for now... let me tell you that if you are going to rewire and gut the entire thing, you better have some time on your hands. I actually had the problem of not having the right socket to take the rear speakers out so I had to figure out how to wire to them through the existing wires... actually was pretty easy once I bent myself in to an unconfortable position

And just to let you know I have all the factory speakers in with the new head unit minus the amps and I do not like the sound at all... no bass what so ever (actually very minimal) but if you do not want any bass then it sounds ok.. not crackling or humming... just a pain to install..

my next thing is get the right tools, replace speakers, as a sub of some kind

Yea unfortunately all of that is true about the MACH system. I used to work for Circuit City and I did a huge system in a Mustang with a MACH system, all new speakers, 4 channel amp, 2 channel amp, single 10 inch sub, and a radio. Everything sounded awesome when it was done but I will warn you it is ALOT of work to rewire that car. I think its worth it if your really into car audio, but if not MACH sounds ok to me
