Another Mach 460 question, is this a possible solution?

First off, I'm talking about the front subs only and am not much of an electrical guy, but I don't see why this couldn't work. Sorry for the bad schematic, but...Red is hot, black is ground and blue is wire I need to run. As far as I know the factory setup is kinda like this,

what if I take the positive of the passenger side and run it under the dash to the positive on the driver's side, run a wire from the negative of the drivers side, plug it into the positive on the passenger side, and hook up the factory negative on the passenger side and the factory negative of the driver's side, running another wire under the dash (tried to show in this picture).

The second solution is similar, but only uses the power and ground wires from the drivers side, cutting the power in half.

Is there anything wrong with my thinking, I realise a 8ohm load isn't s good as a 4ohm, or the less power, but it shouldn't be too bad should it?

What are you trying to accomplish? I don't see any good reason to double the impedance.

The only thing that should be done with the Mach 460 system is to replace the stock headunit with a good one and run it. If one wants to upgrade the stereo in a Mach car, time to run new wires. Honestly... a Mach system in good condition with a nice headunit is going to sound great to most people.

No, the amp is in good condition, and I love the sound, but the front subs have been blown since I got the car, so I just took them out and ran only the rears. I got ahold of some 6.5" subs, but they're 4ohm and I already have my interior taken apart due to my sister backing into my car and repainting it myself. If this will work, then the wiring part isn't hard and I'll have 2 extra subs that I never had.

The best thing you can do is find a pair of 460 speakers online. I found a pair that were in excellent condition for 20 bucks. I wouldn't try and mis match any thing. If your going to do that, your best bet is to pull out the whole Mach system. I would strongly suggest against trying to get 4 ohm speakers tied into it.

Agreed, find replacement parts from another Mach 460 and just go with that. The Mach system is all proprietary, its kind of a jury rig job to properly get an aftermarket headunit in there as it is. Even tho once you get the amps manually adjusted it sounds great.

My headunit went in pretty easy, and the sound system isn't exactly anything I want to spend money on, so I'm not gonna spend $40-50 on paper woofers

Then your best bet is to pull out the Mach system and replace with aftermarket.

Personally I like the Mach 460. Get aftermarket deck and call it a day. Unless you listen to a lot of Bass Music there's a guide that shows how to install aftermarket subwoofers that work with the Mach system.

I keep saying, the Mach system is good for a loud sports car that you want to be able to listen to music but also very often find yourself just enjoying your exhaust/motor's "music". Paper speakers and all.


But its also much easier to install a set of four 6x8 two ways in the car with a decent headunit and bypass the little stock amp in a non-mach car. I did this with my 95 Cobra and then my buddy who was into "systems" sold me his old sub setup for almost nothing and we installed that thing and it was a damn good stereo.

Ok, well since no one answered the question whether or not it would work, I did it anyway and am glad I did. It was pretty easy to wire, and I still have my stock wires. I don't understand why everyone acts like it's a big deal, and if I wanted I could have put in 2ohm subs instead (but hey can't beat free). I never realized what I was missing out on with the bass on my legs, since I removed the blown ones when I got the car four years ago. I drove it for 40 minutes at 20/33 volume after a days work in the Texas heat...so I'm prerty sure it's safe to say it works.

Improper impedance will put extra strain on the head unit and amplifiers. The life span will be shortened. It's your car though. Two people answered you question. It shouldn't be done.

That is the only time that I've been answered and would have been nice to know beforehand, only thing anyone said was their suggestions (that's not an answer, I figured everyone thought it was too much work). I don't see how that would effect my headunit, maybe my amp but I've got an extra one of those. If I would have put 2ohm subs in there, then I wouldn't even have to worry about lifespan because there would again be a 4ohm load on the amp right?
