With the top down and the partitian in the way how does the sound get to the passenger compartment? The only sub box for C6 verts is the Madvette corner cubby box that faces the toward the front. It just seems that the sub would be rattling the trunk and not sending much into the cabin. I'm not trying to be a smart ***, I'm trying to learn. I've been reading your posts for the last several years and I know you know your stuff. The sub issue is what's keeping me from doing any sound upgrades to the '08. I don't have the time or money to blow experimenting with subs only to find out that I can't get the sound I want.

 

i think subthump makes a box that will fit a vert also

u say how will the sound get through with the stuff in the way. 90% of cars have a rear deck and thick back seat and the sound gets through it no problem. With lower frequencys you are going to feel it more then you are going to hear it which is why they say with a properly tuned sub setup you shouldnt really be able to tell where the sound is coming from

 

According to Sub Thump's web page they only do C5 boxes. I'd feel a lot better if someone would post what they've done and how it worked. A vert has little enough trunk space as it is and I be curious as to how much space the Madvette box takes up. Also, the way the box is made the choice of subs will be limited due to depth available. There's little information on Madvette's site about the enclosures, only a phone number to call. I'll try the number and post what I find out to this thread.

 

Ok, I just ordered these.
Now I need to know what amp to buy. I'm ok with getting something used so I just need to know the information I should be looking for to make this setup work great.
Sorry, I know nothing about this kind of stuff. I just wanted sound behind my seats and this looked like the best solution for me.
All suggestions are appreciated.
Thanks

 

Look for an amp that puts out 250-300W RMS at 4 ohms. That can be a single channel (mono) amp like the JL 250/1, or a multi-channel amp with 2 channels that can be bridged together totaling 250-300 at 4 ohms like the Alpine PDX 2.150. Cheaper amps can be found, those are just examples.

Edit:
Do you have any plans for the other speakers, or just to add the sub?

With that much power going to the subs, the stock amp will be a bit outmatched. Have you considered removing the oem door setup and replacing the sub/twiddler combo with 6.5" components, then using a 4-channel amp to supply the doors and sub? If you want, you could even keep the stock amp feeding the rears.

 

I'm clueless as to what you just posted.
I thought I was just adding an amp and two extra sources of sound behind the seats. Really, like I said I'm not sure of what to do. I'm very interested in what you recommend I do with this setup?
I know I need to buy the amp but what else should I do to make this a complete nice working setup.
Never thought I'd be getting into spending as much as it looks like this will end up costing.
I appreciate your input. Thanks.
For the doors, etc. what do suggest brand wise?
I wish I knew electronics, but I don't.
Glad to get advise from those that do. Again, thanks.

So now that I've ordered the setup above and have a couple of amps to choose from, what other components do I need to make this setup complete?
Also, how much money are we talking?

 

there site needs updating then, because i know i have had people order from them

 

I have an Alpine MRP-M450 sub amp that I will let go. It's a few years old, but in like new condition. This model has been replaced with the MRP-M500, but its no slouch. Wired to two 8s it'll put out 400 watts. I had it wired to two 8" Infinity subs in my '04 so I know it'll kick what you're buying. With the speakers behind your head it'll part you hair. New the 500 goes for $180 plus shipping, I'll sell you my 450 for $100, shipped and a guarantee it to be in like new condition and to work perfectly.

 

Oh boy

If you're that clueless electronics wise, you might want to just jump on the offer above for the $100 mono Alpine amp and get your feet wet with that. You can always do more later if you want to.

To get the new amp/subs working you'll need to tap into the radio harness somehow to get the music signal and power trigger that will supply the new pieces. The easiest way to do that is with the ADD-GM24. If you can't find one of those in stock anywhere the AOEM-GM24 has that part in the package, but costs more since it also has the OEM1 (which you don't want to use). Approx $10-15 for that.

From the ADD-GM24 you need to run 3 wires to the amp. Music signal and power trigger. Misc wires/connectors $20, but probably less since the kit below should have some of them in it.

To power the amp you'll need to run a power wire from the battery to the amp. That wire will need to have a fuse in it. The amp will need to be grounded, there's a good spot to use near the seat belt roller gizmos behind the seats. I'd suggest getting an amp wiring kit with everything you need included in it. An 8 gauge kit should be fine, $20 tops. I got mine on ebay for $10 shipped, but SE has them also, and you can save on shipping if you get the addgm24 from them also (it's in stock, hurry up and snag it). If you get a kit that has RCA cables and a remote wire, that will save you cash in the 'misc' department.

That's pretty much it, to see more check out this thread.

Looks like another $150-200 should do it. Work on getting the parts for now, worry about the install later.

 

will i need a $200 jl clean sweep to make these subs work since i have navigation? can't recall if that has been mentioned. ill go back and read the entire thread but anyone have a quick answer?

 

Click on the C6 FAQ thread, the entire explanation is about 2" from the top in the first post.
