So, I'll admit that i'm not exactly good with systems or how they are set up. I have a stock headunit, with stock speakers. All I need is just how do I hook it up? I'll be redoing my system next, so, for now how should I hook it up?

 

I believe you just need to tap into the rear speaker wire for signal, and run a power line to the battery. The included amplifier will detect a signal and turn itself on automatically. As close to plug and play as it can get.

 

Sweet. Where's a good place to run wire through the firewall?

 

Look up and behind the dash (on the driver side). There are many existing grommets up there for the steering shaft, main electrical harness and other items. You can puncture one of these and slip the wire through that, just big enough to push a wire through, and of course don't get too close to the exhaust or any moving parts.

Optimally, dremel out a small hole and insert your own grommet to run the wire through.

 

Ok, ups brought it today. there's a connection called "remote" wtf?

 

The Remote line goes to the head unit to sense when you turn it on. I thought the MTX Thunderform's I've read about on crutchfield will auto turn on based on signal coming down the speaker inputs. So I guess it includes both? The remote is probably more reliable if you had to choose between the two.

Should be instructions telling you what goes where. Post back once you got it hooked up or if any more questions...

 

You can use the acc on wire on the stock head unit as the remote wire. Just don't turn your radio on without the power wire to the sub. An amp can actually power itself through the remote wire causing the fuse to pop and being a royal pain.

 

Are there any good grounding points nearby that might help me out? (behind drivers seat)

 

Some use a seat bolt. I would just drill a small hole, scrape off the paint all around the hole, crimp on a "eye" or circular terminal to the ground wire, and mount it. Then a little paint on the underside/topside to seal it up and prevent rust.

 

What would a good wire size be for the powerwire?

 

1/0 wire duh, go big go home is the rule,at lest 2ga, if not 1/0, use 4ga for remote wire and some beefy RCA cables, for ground use a 18ga wire, helps ground noise duh, use at least 20-30 different ground spots, so u know one will be good, u might want to check powering it with solar panels also


:) j/k

 

thats pretty intense :p What wire behind the radio can i splice into to get the
remote from?

 

its a blue remote wire/ power antena , what kind of radio u have?

 

the stock one.

 

Lookie what I found here:

I recommend installing a cut off switch on the remote line too. It's very handy when dropping off your truck for service, or the car wash, and you don't want to have some minimum wager earner blasting your stereo into oblivion. It's also handy when you have 2 amps, one for sub and the other for speakers. Really makes it easy to tune, or just to let the sub rest if you're listening to talk radio.

 

Ok, I got it all hooked up and it doesn't seem that it's working. I put my hand on the sub and it isn't moving. I had the ground originally on one of the seat bolts... nothing. I moved it to the seatbelt bolt on the drivers side... nothing. I haven't checked the fuse yet, but there is a green light that is on so I'm assuming that that isn't it either? I tapped the remote wire into the lt green and purple wire behind the radio and have the power wire going to the battery. I also have the rear speakers plugged into it. What gives?

 

hmmm so theres a power wire on it thats lit up, but no sound? double check the connections you made between the sub and the rear speaker.... something must not be hooked up right. i'm not too familiar with mtx thunderform boxes... so you have a ground wire, a power wire, a remote wire, and then a ( + ) and ( - ) for the speaker right?

 

yea, the inputs for the speakers are the ones where you push a little clamp thing and put the wire in and let it go. There's two of them for the rear speakers.

 

so do you have both rear speakers connected to it? i think all you'd need is one set. splice a wire into the positive of your left (or right) rear speaker and connect it to the positive in on your thunderform. then do the same thing with the negative. if that doesnt work... theres another problem somewhere. i'm still a little unclear on the wiring of thunderforms... whats the model number of the one youre using? a link would be helpful too ;o)

 

both rear speakers are connected to it.

Did I use the right wire for the remote signal? Also, there are what looks like rca inputs for low level. Should I have something plugged in there If i'm using the stock cd-6?

 

you currently have the remote turn on connected to 12v constant, which will work fine (that shouldnt be causing the problem). i'd personally connect it to the accessory wire which is the yellow/black wire. i see that the amped thunderforms take two channels and bridge them (in your case, right and left rear) so check all 4 connections once more, making sure that pos and negs are in the right place....

Radio
# 12V constant = lt. green/purple
# GROUND = black
# 12V hot in run = yellow/black

Speakers
# LR SPEAKER: (+) = gry/lt blu, (-) = tan/yel
# RR SPEAKER: (+) = org/red, (-) = brn/pnk

 

ahhh... what you could do is hook up an rca line out converter. it will take the wire signal from your deck and convert it to rca outs, which is a better way to wire up the box in the first place. although i cant imagine that it would be causing this problem.... you can't possibly need the rca's AND both speaker connections for the thunderform to work properly... (never used a thunderform though, so not sure)

 

Ok, If I were to hook up the rca converter would I need the speaker wire inputs? (i guess we'll know in a little bit) I'm also going to move the remote wire.

 

you shouldnt need the speaker wire inputs connected to the thunderform if you change to rca's.

 

make sure you tapped into the speaker wire and didn't cut it, or have a loose connection. You should get some output, unless both pairs got messed up.

An RCA converter wouldn't just "fix" a problem like this, especially if you use the same speaker wire or tap into the same place. It's basically another method of signal delivery. RCA is better than speaker wire, but the original source is still speaker wire. Plus the less connections the better.
