Ok i got my 2 "highly acclaimed" sound splinter rli 10's in the truck and i had a box built by mr. marv in LA. BEAUTIFUL BOX. i have never seen such a meticulously built box. I was gonna carpet it but there is NO way i can do that. its truly a thing of beauty. anyways thats not the problem.

I CANNOT get these subs to sound right. I am sending then 320rms a piece and they move like they are supposed to but they just aren't loud. I can reach full excursion and then they bottom out. they are sealed with .65 cubes per sub. the way they are wired is i have my amp bridged and the positive splits into two wires and the negative splits into two wires. Then they go into their respective terminal board cups. inside, one goes to the positive of one voice coil and negative goes to the negative of the other voice coil. then i have a jumper that connects the other positive and negative. this should give me a 4 ohm load correct? they are dual 4 ohm speakers.

option #2

is there anything that could be wrong with them that would cause this? I am a few more bad bass notes away from giving up on internet acclaimed speakers and just getting a set of JL 10w3v2's

Ummm...I'm confused one EXACTLY you have your amp/speakers hooked up. Is this a dual chamber or common chamber box? Also, what is your amplifier?

I think maybe you need to check the wiring of the subs and amp. Sorry not much of a help, your description is confusing at best.

its seperate chambers. .65 each. amp is a phoenix gold 600.2 ti. birthsheet says 640x1@4ohms

mine is option 2 on your soundomain wizard.

i dont know what to tell you but i agree its confusing reading what u typed. try posting on the soundsplinter forums, you can get a direct response from mike, he will help u out personally.

ok. single strand of speaker wire coming off the amp.

it hits a splice and becomes 2 strands of speaker wire.

2 positives and 2 negatives

one strand goes to each sub.

the sub then had a single piece of wire that goes from the neg on VC1 to the + of VC2

i am going to put a dmm on them right now. i'll let you know what i find.

Ok yoru doing something wrong, it does not sound to me like your amp is properly bridged.

On most 2 channel amps in order to bridge them you hook to both positive outputs, make sure this is the way your supposed to do it with your amp.

one of the positives becomes a negative.

Now if you did this correctly, make sure your VC's are set up for 8 ohms each. If they are then you want to run the speakers in parallel, I would not suggest splicing the speaker cable unless you have some real heavy duty wire. Better to hook both subs right to the amp on the bridged channel.

as far as the VC's go Hooking the - to the + Like this (+)_(-)-------(+)_(-) (BOOBIES) hehe means they are wired for series so you add the impedences 4+4 is 8 so that is correct.

If you hook them up like this

(+)(-)

| |

(+)(-)

This is parallel so you get (4+4)/2 = 4 ohm load

So then, wiring them to the amp in parallel you either get (8 ohm load)/2 = 4 ohms or (4 ohm load)/2 = 2 ohms

Now What I think you have done is this

(8 ohm load )/2 = 4 ohm to one channel on your amp (cause it's not bridged correctly) so your probably getting about 80 watts to each sub.....

It sounds like you hooked to the positive on one channel of the amp and the negative of the other, now the negative end does not really matter which you use because neg is ground, but you would only be using 1 channel of the amp for power. and simply gounding it to the other channel. Thus your only feeding them 1/4th of the power they need!

4.2 ohms combined load.

i turned them on again just to make sure and sure enuff, it sounds like i have 2 8w0's in there.

 

[f150_on_32s 10+ year member]

its left+ and right- to bridge this amp. PG 600.2 Ti

so you think i should just run two seperate strands and tie them both into the amp bridged?

 

[saywhat? 5,000+ posts]

maybe its not tuned right? (your amp)

 

[f150_on_32s 10+ year member]

tuned right?

amp is at 3/4 gain, bout half bass, signal going into it is from a memphis eq, LP filter at about 80-85

 

[f150_on_32s 10+ year member]

going back out. gonna try taking the eq outta the equation.
