i have 2 10 in. kickers in a ported box. im havin a problem with the thumb of them i have a 600 watt amp bridged for both tens. i have a hatch back and was wonderin if i should change boxes or get more power to them.. then i have a rhythmic thump. i was wonderin if i could be the amp causin that or if the amp is just under powered.. i have a sony explod deck

 

so what exactly is the problem?

 

i thumps in a continuous rhythum with no music and i have a 90 integra hatch back and was wonderin if a ported box was the type that is right for the car

 

what gauge wire you running to your amp and how many ohms is the amp????

 

the wire is 8 gauge i belive and im not sure bout the ohms i would have to get back to on that i have had it in my car for bout a month. i didnt install it my friend did and the amp was his he gave it to me

 

I dont understand what is happening... there is a constant sound coming from it? "thumb"?

 

the subs flex and thumb with no music being played... thats all i can say i dont know how else to explain it..... i think its under powered

 

do you mean THUMP?

Does it do it if the stereo is OFF? like physically turn off the head unit, and see if it still does it. Try a different preout. Unplug the rca on the amp and see if it still does it.

 

If it does do it with the stereo off, either try moving the preout like Jesse said, or try a different wire for your remote. I actually witnessed an install with a Visonik amp, high low converted, where with the radio on it worked fine but if you turned the radio off there would be a constant THUMP, like 40hz or so

 

ill do that in the morning and yes i mean thump sry was doin like three things at once at school.... even with the sterio off it does it
