Again... ive got 2 12" cvrs. One of them is hitting the wrong way... ive got both of them wired the EXACT same..
I have all of the positives wired together and all of the negatives wired together. Then i put both pos. into the pos. part of the amp. Then i put both neg. into the neg part of the amp. Wtf is wrong? If one is hitting the opposite way, in a sealed box, is it taking away some bass?

Depending on what ohm subs you have these are some of the wiring options you have. These first ones are for 2 dual 2 ohm subs

Wiring Option #1

Wiring Option #2

Wiring Option #3

The second option you have is for 2 dual 4 ohm subs

Wiring Option #1

Wiring Option #2

Depending on the ohm your subs are and the lowest impeadence your amp can go wire your subs according to the diagram that best suits your setup.

wire each one separately and see if they work. if so, wire them up like the pics above to the right load.
Also a dmm would be able to tell you if the coils are bad. if they are dvc, maybe one of the coils is bad.

Check each voice coil with a DMM and post results....

take the sub out and get yourself a battery and test it.

check wire connections in sub box.(terminals) at subs and at termnal cup on inside if box
or

move working sub to non working side(or vice-versa) and see if it works.... if so the other sub is likey fu(ked up. If it doesn't work the wiring/connections are likely the problem
(if done vice-versa the opposite will apply)
or
pull subs out
check each voice coil with DMM. post results.
check tinsel leads
check voice coil jumper wires


just some suggestions

Well what i found out was, the wires that attached to the box were holding on by a tiny thread and a current wasnt getting through it.

Omg i thought it was loud before holy hell... its literally twice as loud.. it was only 1 sub before. But i turned the gain down a lil since its only 300 watts instead of 400. If i put it all the way up wont it send a clipped signal and that would be bad i assume. What should i listen for? People are hitting 150 Dbs, if i hit 100 it sounds like they are gonna blow, idk the diff between too much and just really loud.

100 decibles is barley above a wisper..



so it was the wiring.... thats the usual suspect...especially in low power system, where you are not as likely gonna blow subs with such little power... Unless they are really low wattage/quality subs and clipping their signal tring to more outta them that is possible.... Does that make sense?

yea im more worried about under powering them and pushing the amp too hard, so then it will send a 400 watt signal when its only capable of sending a 300 watt. so it will b clipped, if u understand that.

Im sure they will be fine, im sending them 300watts each, they are 400rms. And ive got the gain down to like 3/4, but i use the remote bass knob and i turn it all the way up.

There is sooooo many incorrect statments in that post^^^
1st
"yea im more worried about under powering them and pushing the amp too hard"

U cannot hurt your subs by underpowering them.... Otherwise you would damage your subs every time you turned the volume down..
2nd
"so then it will send a 400 watt signal when its only capable of sending a 300 watt. so it will b clipped,"

Your sub does determine how much power is being drawn from the amp (with exception of ohm load) in the form of a clipped signal..
In other words the subs recieves a clipped signal(determined by the amp and h.u., ect) and does not draw a clipped signal by simply being a higher rms rating than the amp.

You amp is gonna send whatever signal it's told to (by it's and the h.u.'s setting. This is a general statement, as there are other determining factores that play some role in a clipped signal..

I hope that makes sense to you.... I kinda confused myself..lol

another example..
If you were to take that 6oo wrms amp and try to push my Solo X (d2) sub-2500 wrms.. That sub is not gonna try to draw 2500 wrms outta that amp..... It gonna play whatever signal the amp tell is to..


lol
