It has not been dynomatted and the trunk does rattle but not too bad. I will dynomatt it soon. The subs have not affected the bose system at all. They seem to work good together. The bass sounds great

Mikeb, ask EASTMOON about the "flat cover" you can get for that cubby hole, that way you could use the rest of the trunk space without squishing the Amp.

EDIT: nevermind I just noticed your custom cover.

Did you try it at all with the woofers facing backward? What/how did you get the line input into the amp?

how much power are you running and how much was the install total cost?

did you splice into the rear speaker wires??

more details please...

That is a real nice looking job and I'm glad to hear that doesn't mess with the audiopilot. How many watts on the amp?

-JiM

The amp is 600 watts and two channels.
Each sub takes 300 watts they are JL audio w3 subs.
Total price for the box, 2 subs, amp, custom amp tray cover and installation was $700.00

The rear speakers were not tapped into. The subs sound great and I haven't had any problems with the bose speakers. I had a shop here in cali hook it up called advanced car creations.

if you didn't tap the speaker connections where is your input source scoming from -as there has been much speculation on the impedence of the BOSE system..Did you connect directly to the rear amp/xover--if so where and at what output/impedence rating?

Like I was saying the shop did the install so I can't say for sure. But I don't think they tapped into any of the stock bose system. They just added the amp and subs and of course the ground, remote, power wires and rca wires.

Rca wires.. exactly. Please ask them where they attached the RCA wires for signal input. The deck?

Whoa.. cool.. are you still using the stock rears or did you pull them?

all bose speakers are still in use and I will ask the shop where the rca's were tapped into

good man

glad to hear it, you install sounds really nice and looks good too, hopefully ill get around to getting some money and adding some subs...

im thinking of putting in these alphasonik 800 series 10inch subs and i dunno what kinda amp, but i dunno lol

anyway, thanks a lot and keep the info coming

I'll call the shop that did the system tomorrow and see if they used a hi low converter and where they tapped in to make it work

Sweet install.. I like the amp cover..

I went to tweeter last week and they said you can tap into the rear speakers without splicing the wires. I don't know what kind of connection it is, but the new amps have automatic sensors that judge when its getting power and can "figuratively jump right into the music" and have it sound great. I was looking at putting the same speakers in but only 10's. They would fit in on the side where there is a reasonable indentation in the sides of the trunk. They can custom make a casing for them and showed me before and after shots of similar trunk set ups. They said its not that hard to tap into a bose system if you buy the better equipment. I think after all is said and done it will be $350 for the amp and install and another $500 for the two subs. I have to get two enclosures made since one 10 will go in both sides. I think it might eliminate my ability for a golf bag though. I thought about putting them back against the seat, but that would eliminate the advantage of being able to go from the back seat to the trunk. I like to fish, and need to be able to put fishing poles through the rear seats. I'll probably get that work done in the next two weeks and post pics when I'm done.

You guys are right. I was looking at my subs last night and the rear speakers is what the shop tapped into for my system. I will take pics later. btw the subs sound really good

here is two pics of where they tapped into rear bose speakers to add my 2 subs

and..

ahhhhhh another fisherman!

thanks for the pics dude

Focus! Focus! ;)

But where does the POWER come from? Is it run from the bat or is it stolen from the BOSE amp as well?

Power is ran from battery

I saw and heard Mike's set up in person on Saturday. Very professional install job with great sound.

Congrats Mike.

The only problem i see with that is they tapped off the high level of the rear speakers, so if the bose amp is putting out distortion, it's feeding that to the input of the amp. Any time you add more crap, splitters, crappy cables, etc, it introduces more noise and foreign signals into the system. Seeing this is for the subs, you shouldn't have to worry about it that much. I'm an audio nut, i just took out my system out of my trade-in and should finally be getting my 8 in a few days hopefully. If it sounds good to you, then leave it... I'm worried about that that amp getting hot under that cover. I have two 600-watt infinity kappa amps driving two dual voice coil 10's. For a while i was running it in series-parallel white created alot of heat... good for the winter time... but it was nice and LOUD. then i switched them in normal stereo mode, so the amp saw 8 ohms each, it ran nice and cool and kept the distortion down. You can never have too much headroom... keeps the square waves away :)

The amp is powered by the battery and the ground is ran to the fuse box. The RCA's are connected to the rear speakers. There is no distortion or any noise from any foreign sounds. The thing is that, the amp has it's own built in bass caps and it's own built in crossovers, so no noice is getting to the subs but solid bass. As well as no noice is coming from the amp the Boss sytems.

If you are questioning who I am, I am MikeB's friend. I'll do periodic fallow ups with you guys to explain ever detail about built up an RX8. MikeB can only explain so much..LOL J/K

mikea is right-- I supply the car and money he does all the work.

Love friends like that

I don't have my RX8 yet and haven't seen one in person... My questions are, does the rear seats fold forward to make an opening through the trunk from the cabin? Is it possible to totally remove the rear seats?

if ever I can remove the rear seats, i'm planning to flush out the two 12" speakers facing the front of the car

back seats don't fold down. you could remove them but I wouldn't

rockie....




for 1 , free air style is not worht the $, 2 if you seal them, it is better to face the trunk not the front and 3 removing the back seat will kill an important essence of structure of the car, almost like an insult.
I recomend, 1 learn, 2 think and plan, 3 act wisely .

Ya, I'm not trying to diss out the structure of the RX8. I love the RX8, it's just that I don't have any use for the rear seats and plan not to sit anyone in there. :D I'll be putting the speakers in a sealed box so I guess it will almost the same as facing it toward the trunk.

Where was the Remote Turn On Wire connected to?

Errr, wrong POD, it does make a difference if you face them in the front. If you face your subs in the subs your basiacally getting half if what you pay for. If you want the deep gut-rattling bass (i live for that feeling) you need distance from the subs and where you are. if you face them backwards you have to measure the distance to the trunk, and then to your ear (bass frequncies bounce off), if you face them towards the front you have less distance, thus less bass. Just a suggestion POD. Me, I have 3 JL Audio W7V12's in a custom box waiting to be fitted in my RX-8 (still waiting for it)

wow
3 12inch w7's
do you have pics of the box

ok thanks! I only have 2 RF Power HX2 12" RFR3112 that are also waiting for it's rightful home (d' trunk).

mikeb-
what are the dimension of the space where your subs are in?

here are the pics douglass

Hey , Mike A or B, Can you get your volume on your deck above 22 witht he subs staying on?

If so what is the bass setting on your head unit?

its mikeb===mikea is my best friend
however I play mine up to 28 and bass stays on as normal
I have bass at -4 and treble at plus 6 on head unit

Hi, can anyone tell me where the remote wire was attatched too. I'm hooking up a system, and can only find the contious power into the bose amp. Any help would be awsome!!

Thanks!!

Mikeb,

SWEET looking setup!

Now, here comes the big question...

IF you had it to do all over, would you keep your current setup or would you go something similar to:

(assuming this could be done with 12's)

http://www.rx8club.com/showthread.php?t=41513 (http://)

Splice it into the center console lighter green wire(in the middle compartment). It will come on whenever the key is turned to any position. Worked for me, but Im just careful to not play my subs for too long without the engine on.


10w7 + 4 guage wiring + JL 500/1 = mucho de la pimp.

as for the 3 12 w7s, unless your gonna remove the back seats and have some crazy custom setup its such a waste of money.

My box is 1.34 cubic feet inside to fit my 10w7, and it takes up a little less than half of the entire trunk space amp and all. The 12w7 requires 1.51 cubic feet to conservatively sound good (which I assume you want since you attempting to get 3 of them). thats 1 foot * 1foot * 1.5 ft. One foot is about the usable interior box height of the trunk, (because you need to factor in the width of the box material). Just one 12w7 in a sealed enclosure is gonna make your trunk unusable for anything but two or three plastic grocery bags of towels with the amp. I know, I tried to fit a 12w7 in there.

And thats using the sealed box measurement! If you really wanted loudness, and I assume you do, you will be using the ported enclosure with an interior volume of 1.89 cubic feet (you need to factor in the driver), With the extra material required for the ported enclosure its gonna come out to be 1.25ft * 1.25 ft *1.8 ft. With the jl 1000/1, thats the ENTIRE trunk for just one speaker used to its full poential! 3 in one trunk setup correctly is impossible!

And if they do it, they threw some halfass setup together just to steal your money. If they even use just 1, its gonna need to face the open cabin because their wont be enough leftover airspace in the trunk to make it effective (might as well just stuff a pillow over the speaker).

The only way 3 could be done, would be to remove the back seats, have a ported speaker fiberglass enclosure column occupy each of the places where the back seats were, and have the third and final one occupying the trunk area with the 3 jl 1000/1 amps. Then if you do plan on using that much power, you gonna need a stonger alternator for your car, a electrical system grounding kit, a few extra dedicated audio batteries and a capacitator. The damn things gonna weight about 350 - 400lbs!

IMPOSSIBLE!

posting to make pictures appear

damn this was a long time ago

Holy Thread Resurrection!!

:p

hah since this is back up. hey mike. what LOC (Line Output Converter) did the installers use.

It looks like this....
