problem with subs

[oneforyou 10+ year member]

so i was thinking one of the subs is blown. I had a 2 channel amp running to 2 test speakers(SPL) and if you have one speaker hooked up it hits pretty hard. If you hook both up it gets really light. I though it was a voltage drop or blown sub but it will do it from either speak not just one. Does it sound like amp problem or charging problem?

does the amp have enough watts to push both?

yeah. amp is 400 watts X 2. subs are 250rms spl's. they guy that gave them 2 me paid 20 bucks each. what do u think?

 

[oneforyou 10+ year member]

440 rms 2ohm i have tried at 4 ohm so i didnt blow sub pushing out about 300rms

now is that 440 bridged?

one is wired outta phase swap polarity on one sub when you hook up both and see if it fixes it

i have checked the wiring on both subs. it has been run bridged and not. i have run subs series and parrell but it doesnt change. every which way you try it still same type of results.

im going to try and find a different pair of subs somewhere just to test.

he means on one of the subs put the negative in the positive on the amp and the pos in the neg

just because thats what the little tags say don't mean its right. wouldn't be the first sub i've seen labeled wrong. just try it and find out......
