please post what you think of the set up.

it won't be hard for cops to find you lol.
It looks like a good setup. You should post some pics with some good light so we can see this masterpiece in more detail

Chief

its a thorough audio setup. looks like a decent install. but you are going to get flamed i think.
i like it, but i wouldnt have it in my rx-7, in my daily driver civic im putting together i would, though.
did you by chance buy some dynamat? i heard some rattling in there.

Wiring needs to be cleaned up - it's almost a fire hazard.

You should move the sub away from the rear "wall", as you're probably choking the output being so close - have you experimented with moving the box around?

With the size of that box in that trunk there aren't may options. but i have faced it forward and have noticed about a 2 DB decrease on the meeter and a loss in some of the more low end extended frequencies. and as for the dynamat, no there is none due to the fact it would be hard to remove and I planed of restoring the whole car to original in the next few years. also i intend on getting a subaru baja where i plan on doing a much more extensive set up. I figured i would get some flaming about the cutting for the rear speakers. I my self was very hesitant on the matter but there was already damage done to it by the previous owner and it needed to be replaced anyway so i figured why not for now.

Not to sound rude or anything but how is it a fire hazard? All of the wires i used are good and have a thick protective casing.

More wieght in an already fat obeas pig of a 7. But hey I think it looks great. I'm up for some good pics with better light. Great job.

RX drift

When I was working on it with out the sub box in and when I ran after there was a noticeable difference in performance. But now that I’m out of high school she is more of a week end cruiser so i am fine with a little loss of power.

And when i get a chance tomorrow i will take some more detailed pics and post them.

I used to install and tune competition level sound systems back in the day.
Trust me - your wiring looks pretty bad, and it can be cleaned up if you wanted to.
As a rule, you want to try and minimize wires being exposed as much as possible.

I just glanced at your pics, but are you using a piece or bare particle board to mount all that stuff on?

Holy weight, theres alot there but sounds nice......Im just runnin' Pioneer products with a 12" pioneer compition series sub. Thats enough for me and its not too heavy!!

RX drift

Its actually cabinet grade ply wood, I know the guy who owns a shop so I can get some good prices on stuff. How can I clean it up and make it a little safer? the board is all bolted in and shimmed up so it doesn't flex. there are no exposed screws poking through, i put blocks underneath so the ends are covered. As you can see in one of the other pics i put a wood strip under the mounts for the amp so there is air circulation under them.

Here are some more pics. And as you can see in one of the pics i use a bass blocker on the 4s to make it all a little cleaner.

RETed

Wires should not be "hanging" from the speakers.
They should be bundled and run up and along the sides - hidden from view and out of the way.

The mounting board should be covered (how's about carpet?).
At the very least, it keeps the wires from abrading from the edges of the board.

Like I said before, exposed wires should be kept to a minimum.
I would drill holes through the board and run the wires through the board to keep from exposing too much wire.

nice song, i dont see a point on makeing it loudenough for the entire state to hear it though.

RX drift

True, but if it can hit 127 and still be clear, just imagine the quality of the normal db range.

Well, I think thats pretty nice. I'd just clean up the wiring a little and maybe consider some carpeting. But thats just my .02. Overall, amazing set-up.

EDIT- all this in an auto? lol

RX drift

Thanks

well i had to take what i could, there ave VERY few 7s out here. I have seen like 4-5 total in like in a good distance from where i live. but that does make owning one especially a less common vert even better.

whats the song in the second video?? starts with the piano.


seems like a nice setup, i agree with everyone else just tidy up the wires.


thnx

not to sound like a dick or bash your ****....

but you put pure crap in your car. you should have researched car audio a little more. and not gone with the Best buy Special...

but im sure it sounds ok.

im sorry 126 db is childs play. Nothing special WHAT so ever. I did 148 in my old cavalier with no problem. (and remember every 3 DB your gain is about twice as loud)

Also capacitors are useless. No one has ever did 140 DB then installed 5 capacitors and hit 143. :P Congrats on your very bad build. Your pretty much got all the worst quality stuff you could. Don't start clipping that sub or its's going to go poof.

By all means, be happy if it works for you. Maybe you just wanted the little extra down low. But for gods sake, clean it up. What is the box tuned to btw?

jonesfromindia

its every 10 dB the sound gets twice as loud. most normal humans notice a change in volume at 3dB. install isnt that bad. its the equipment. i think he knows about clipping, hes not a dumbass, he just hasnt been introduced into GOOD car audio.

and capacitors do absolutely nothing. they dont have time to recharge from the voltage drops. and if you were worried about that, you should have went with 0gauge to a distro block then to 2 gauge to help with voltage drops.

RETed

Actually, you're both wrong.
It is generally agreed that 6dB is considered "twice as loud".
3dB is what most people would hear as a "significant increase in volume".
1dB is the absolute minimal difference any pair of human ears would detect as a change in volume.

well when I went from 1 12 to 2 12s I gained 3 db and when I went from 1 15 to 2 15s I gained 3 db. So im going to say 3 db for me. Also every time I doubled my RMS W I gained ~3 db.
Obviously there is no solid facts, its just perceived or they think. :P

needless to say, there is a huge difference between 123 and 140 haha

RETed

Something is wrong...

Double the # of drivers, you're supposed to get a 6dB increase.
Double the power into a single driver, and you get a 3dB increase.

Destructive interference?


-Ted

jonesfromindia

technically im not wrong. neither are you. its a fluxuation between 6 and 10dB. most people just say 8dB. i got my information from a microphone teacher/recording engineer who knows more about mics than anyone here or in most parts of the world. so im not making this up.

Not if you double the driver, but dont lower the ohms on the amp or add another amp. If you have 1 driver with 600 W, and then 2 drivers both only getting 300 W there will only be a 3db gain from my experiences/tests. But anyways who the F cares, rx7s are VERY bad competition audio cars. This really shouldnt be in the 2nd gen specific section.
