sub box

I have two 10" kicker comps (4ohms) in my truck box. I am running a crunch powerone P1-1000.2 1/2 channel amp.They are wired in series. I have done my best to tune the amp to get a deeper sound but it's mainly all highs and mids, I am constantly tuning the amp, I can't seem to leave it and listen to one song, then go to the next without having to change the settings. I get a shallow sound whenever i listen to deep rap. Is there spmething wrong with my box? The subs? Or the amp? if you need more info just ask and ill do my best to come up with the answers.

Here's a pic of it

Here's a photo actually

probably too much airspace in that box for those subs. i know that sounds strange because its a small truck box but i think that might be part of the problem.

its also possible you have the amp set wrong. can you list the amp settings and what each one is set to?

also you could have one of the subs out of phase so try to flip the + and - on one sub and see if the sound gets better.

Yeah that's a hard thing to picture, to much air space. I was thinking about cuttin the box in half but i dont know if that would help or making a new box one for each sub. So make them seperate sub boxes. I have been changing the amp settings constantly I can never find the right settings its either turned up to high or to low, and when the amps turned up it doesn't hit lows very well and when it's turned down, there's not a lot of bass. I'll defiantly have to try switching the + and -. What would that do?

He is just saying one of your speakers may be hooked up out of phase, they should be +- to one +- to the other one then hooked up to the amp the same way. You may have one backwards this by changing just one of the sets of wires could bring back the lack of bass your getting. Its a a easy thing to hook up backwards.

Its does not matter what speaker you do it to. Or just take out the if that fixes it then you can always trace what speaker was hooked up out of phase.

So I have them like this, one speaker has a + wire and it goes all the way to the amp, then on the same speaker I have the - running all the way to the amp. That's the same for the other speaker. So all 4 conectors on the amp are taken 2 + and - from each speaker to the amp. Is that wrong?

its not that serious, it could be a wire reversed inside the box. just flip one side and see what happens. if it gets worse then flip it back, its just something easy to check. dont feel bad that you dont get lows because those are shallow subs and they are in a sealed box and they are under the seat. i think your expectations are too high for your setup

Do you have the LPF turned on on the amp, and what is it set to? Also, if I understand you correctly, it sounds like you are running the amp in 2ch mode at 4 ohms. Did you bridge the amp?

Would I flip the wires on the side of the box or pull the actually speaker out and switch them? I've been messing with the LPF and I can't seem to find a good setting what do you recommend?

flip the positive and negative at the speaker terminal on the box. the lpf is just a filter to help your sub blend more with your mids so its hard to help you set it without first hearing your whole system but i like to stay under 100Hz usually.

I have it for sure under 100hz.I tried flipping the wires and it didn't make a difference, made it worse actually. Any ideas as to what I could put in my truck? What type of box and sub?

Do you think it's my amp? I tried hooking up a 12" sub and it didn't even power it enough to hit at all. Maybe a 1000 watt hifonics amp will do the trick?
