Im thinken about 1 12" brahma with a 1200.1-jbl amp.. since i blew my kicker sub im just sayen f -it and do something right and face the subs in the right direction

 

what was wrong with your kicker setup. my only thought would be the wiring and not the placement, no?

 

I would say leave the new sub in the same location as the kickers where, u get an extra dB boost by using the glass to refract the sound back to the front. Plus u will still be able to see out the back window with the sub set up in the well vs on top of the hump.

BTW the Brahmas are awsome subs, ive seen single set ups that put my current 2-12 L5s to shame

 

iv been told most of the sound comes from the back of the sub and having it set up like that is giving me cancellation .

 

many people, in fact most people with 3rd gens, have their subs in the same place as you and not running into any problems with cancellation. i think you have an underlying problem here other than sub placement.

 

You've been told wrong, leave them the way they are.......

 

how is the sound coming from the back of the sub, which is enclosed in the box going to make more sound than the side that is open to the inside of the car?

 

if you do put it on the hump make sure u secure it good, because have a 50+ lb object come flying at you if u have to stop suddely is not fun

 

I have had my subs on the hump the sounded worse allot of the base gets stuck in the pit.

 

really? do you have pictures of how it was set up?

 

before all my audio got ripped off !#@$$... i had a single 12" sub on the hump in a custom built elongated box, which allowed the screen to still be pulled over it. The sub still sounded good, but the screen interfered with it ... it made a wonderful sputtering sound, heh

overall

IT SUCKED

totally not worth it

 

Yes I can definatley see that happening. Like a constant tapping sound.

 

well i changed my mind im just going to go with a wall of 2 15"s for look at some better sound thanks anyway

 

where do you put 2 15's in a camaro? back seat?? or can you fint them in the well? I had enough trouble fitting 2 12's back there the first time.

 

I am willing to bet the reason you blew a sub is because one of your subs is out of phase (meaning one of them has the speaker polarities, positive and negative, reversed).....which tends to blow woofers and make the system sound like crap.

The setup that you have is the best for sound, the direction is just fine.

Fix you current problem and you should be good.

If your system now sounds better with just one sub running, then you definately had them out of phase.

 

what u mean out of phase? and yes 2 15"s are possible u just gotta use the right 15 and can build a nice box

 

 

Out of phase blow a speaker, NO. Turning the gain and volume to MAX trying to get some base because your subs are out of phase blow a speaker, YES. Distortion BAD for every thing.

 

i'm about to put 2 12's on the hump in a custom fiberglass box, with the amps in the well, but before i did this i had a "well box"...sounded pretty good, the guys on here are right..you probably have phase cancellation, one speaker with the + and - reversed..check/trace the wires....if you think about a wave...when a speaker fires out (+ and -) set up correctly, the air moves, wave sign goes up, then down....you can think of it as if the + and - are reversed..it's firing in when it should be out..so the wave is going down, then up if you will (i know its kind of hard to understand, easier w/pictures)...so when one wave is at the crest, other at the trough..there's phase cancelation and some frequencies will be missing..check your wiring would be the best bet..the one thing that is definitely not correct is that being out of phase will blow a sub..i've had speakers many times out of phase in live sound, running on 5000 watt amps..didnt blow a thing..that's incorrect..too much power blows a sub, wrong ohm load will blow a speaker ..thats it..and the ohm load..will fry, not blow it

 

That is what I meant, he was probably blasting the subs and turning them up more and more because he wasn't getting any bass.

 

ahh..it makes sense now that u worded it that way..u were sayin he prolly cranked it too high because he didnt hear enough bass due to phase cancellation and blew ****..makes more sense now..before i was like hUH?

 

yeah ur totally right.. had the gain all the way up.. and did exactley what ur saying...thats why their blown lol

 

Did you check the positve and negative polarities to see if they were out of phase?

Does it sound better now with just one woofer playing?

 

the headunit went as well.. so what are u trying to say my wireing was messed up? it dont matter anymore .. cause im getting diff subs.. like 2 16Kv.2 Elemental design subs.. and its weird cause they were playing good for atleast a month.. just beat them to death

 

the head unit went also?...that shouldnt have anything to do with the sub wiring....there has to be some electrical gremlins in the car, or a really really bad ground...do you have fuses for the constant power, and the amp?....and the subs, bad wiring caused them to be out of phase, a cranked gain is what most likely blew them...make sure you're wiring things up properly when you install the hu

 

i think what got the headunit was when the amp was on and my ground for the amp got off the car.. it was a big surge.. or the headunit was falty im not sure so this is my plan.. gotta friend to get me an eclipse headunit for the mean time.. getting 2 -16Kv.2 Dual 2 ohm 15"S from Elemental designs, then just using my rf1001bd amp again...in a wall. so hopefully it will be louder then the cvrs.. also the ed are going to be ported in that wall

 

If I were you i'd either get my sh*t together installation wise, or have a professional do your work otherwise you are going to continue wasting money breaking stuff.

What do you mean the ground 'came off'?

Of your battery?

I don't see how the amp and the head unit share the same ground.

You keep saying "it doesn't matter anymore because......."

Hell yeah it does matter, cause if you make the same mistakes, you are gonna have the same results.

 

That'll do it.
NEVER EVER have the ground off of the HU or the amp if the RCAs are attached. When hooking up an amp the connections should be made on order, ground then B+, then Rem., then RCAs.
I don't know what "the ground came off" means, but it ant' good.
The amps ground and HUs ground should be at the same potential. If not bad things happen.
In this case with ground off at the amp (but B+, Rem,. and RCAs in, all still attached) the amp will try to ground THOUGH the RCAs back to the HU, though the HU (and some vary small traces and feedthroughs) and then out the HU ground wire to the HUs ground. This is bad, vary bad as you found out.
And with the "professional" install, I will never steer someone away for having someone that knows all the ins and outs do the work for them. But if you what to do it your self, do it. Just under stand that not understanding ALL the details can kill your equipment or your self. Car fires happen.
I'm adding a line to my sig.

 

ok this is what happended.. and this isnt the only system i have installed.. i learn from my mistakes. I was checking the ground for the amp and places for a better ground .. cause there was a weird feedback. well where the new place was attached i used channel locks.. they fell off.. oh well .. just atleast it wasnt a 400$ headunit..

Where's everyone put their ground at? I had mine on top of the back seat seatbelt where it bolted to the car like i took off the bolt that held the back seatbelt in place underneath the plastic on the side the spare is.. anywhere else that would be better?

 

Run a ground wire shorter than 5ft and find a nice area of sheetmetal to mount it.

Take a wire brush or some sandpaper and get it to bare metal.


Find a screw with a good size washer and drill the screw into the bare metal with the ring terminal in the middle.

It won't come out and is a solid connection.

 

i had an old kenwood setup on the hump...wasnt a fan..the magnet basically is sittin on the wood...keep it in the hole its way better

 

Could still be the HU. It's easy to check and see if the HU was damaged. Do you have an ohm meter? If you measure the resistance from the outside of the RCAs to the HUs ground wire it should read as a shot or less then 1 ohm. It's easy to fix if it is a problem to.
