i have been doing some research on here and have come up with some posts that have somewhat helped but i need a concrete list of what i need. I wanna keep my stock head unit and moons and tunes amp and speakers but i wanna hook up my 10" Alpine Type S and Infinity Reference 310a amp. Can someone just list what i need to purchase to install in the vibe. I am fairly knowledgeable with aftermarket head units but this moons and tunes is throwing me for a loop. thanks in advanceryan

So, this is what you want to do:Keep the entire stock stereo with M&T as is, but somehow patch in an additional amp for a 10" subwoofer (also to be added)?If so, then.... I'm assuming that your woofer amp just needs a line level input from the stereo, and that it doesn't need a crossover or anything.The stock head unit drives the M&T's amp with speaker-level outputs. Therefore you need a speaker to line level converter to hook up your amp. Hopefully Jahntassa can point you to a good unit. (I'm not sure what's a good one)You should be able to wire it (the converter box) in parallel with the front speaker lines going to the M&T's amp. The outputs are designed to drive 4 Ohms, they should be able to handle amp inputs and a converter box at the same time.The line level outputs from the converter box can go to your amp.Anything else, gentleman (& ladies) of GenVibe?

Depends, do you have an 03-04 Vibe, or an 05 Vibe?If it's 03-04, then GMJAP is exactly correct, get a line-level converter (available at plenty of places. Circuit City has a pretty good unit for $20), do a search for M&T diagram, and tie in the unit to one of your speakers. Either front or rear, depending on what you want.If 05, then you want to tie into the existing subwoofer lines.It's late, so my brain isn't fully firing. Does that answer your question?

so a line level converter, tie it in near the moons and tunes amp and run a power wire to the amp and im set?

Jahntassa · Post by **Jahntassa** » Mon Jun 13, 2005 12:21 pm

Pretty much. Plus a remote turn-on wire, which might be able to be found at the M&T amp..

why would he need to tie after the amp?. i would tie it behind the HU. pre amped then to his aftermarket amp. i would think it delivers the same volts as a regular audio output that's pre amped...

on another note. you can keep the stock amp pushing your stock speakers. if you think you might want to go that way... let me know. i'll be having a sony radio soon for sale. my page has pictures.

He's trying to hook up a sub. Nothing to do with the stock speakers.In the M&T systems, you need to connect the line-level converter after the amp, because the signal going from the radio to the amplifier is not enough to properly drive the line-level converter. Most times when you have an external amp like that, the signal from the radio to the amplifier is not speaker level, which is what the line-level converter requires.

well i just picked up a line level converter from my local wal-mart, i cant wait to do it so im heading out right now to install it see how it works

i cant seem to tell which wires to splice into.....i see two harnesses, one is bigger with a blue clip on it, and the other is all white. is the blue harness the harness leadin out of the amp?

Jahntassa · Post by **Jahntassa** » Mon Jun 13, 2005 9:32 pm

They're both kinda in/outs.You can pick any speaker you want to tap into, generally you want to tap into both the rear speakers, so it'll 'sum' the stereo input and give you a little more oomph..In the harness with less wires:Left Front: (+) Pink (-) PurpleRight Front: (+) Light Green (-) BlueLeft Rear: (+) Black (-) YellowIn the harness with more wires:Right Rear: (+) Red (-) WhiteFrom the diagram in this thread: http://forums.genvibe.com/zerothread?id=15103

i can't agree with you. this is the same radio that powers the stock matrix without an amp. so i'm assuming it's got an internal amp... am i right??? the MT amp just gives it a little more juice than the radio would. on an aftermarket radio that had no internal amp, then i agree. we need a guine pig. any takers...???

GMJAP · Post by **GMJAP** » Tue Jun 14, 2005 2:19 am

I would suggest connecting the line level converter between the head unit and amp. the head unit puts out speaker level signals to the M&T amp. (This is why you need the converter)Connecting it after the amp would be ok, but 1) you'll probably get more noise 2) The M&T amp drives 2 Ohm speakers; the line level is probably designed for speaker levels with 4 ohm speakers, so it may not work as well, the signal may be low level.

i just chucked the money to circuit city and let them deal with all that crap.

well that wasnt too bad, i just wasnt thinking, took about 25 mins after i figured out what wires to use, got all the wires hidden and amp under rear left hand passenger seat, now i cant fold the seat down ill have to figure that out someday, and i need a bigger box the one i built isnt big enough, but overall it really made a nice difference in the sound quality

Would you be willing to post a quick write-up of where you spliced in the wires, what wires you used, etc? It'd be very helpful the next time someone has a similar issue. Thanks!

i was gonna take some pics as i went through with the install i was just soo cramped and sweaty i didnt wanna mess around with my camera, but i picked up a (schosce line lever converter)sp? from walmart for 17 bucks. Took out the passenger seat to get to the amp easier. then i removed the m&t amp and disconected the harnesses. I used the big black and yellow wires on the large plug and spliced into them. Located the amp remote wire and spliced into that and ran it to my infinity amp. Everything worked out great. besides the seat not sliding down

GMJAP · Post by **GMJAP** » Wed Jun 15, 2005 6:54 am

For reference sake then those would be the left rear inputs (Ye-, BK+) to the M&T amp (aka outputs from Head unit). Thanks. Cool it wound up being fairly easy!Wonder why the trouble with the seat? Do you think the amp is interfering with the seat moving?

6speedz · Post by **6speedz** » Wed Jun 15, 2005 11:58 am

yeah the amp is a little too thick to fit right under that seat

OK OK i have searched.sub/amp with moons and tunes what do i need?
