First, provide the amp model number. Second, ensure that you are not using a Front or Rear line-out of the radio and have the radio in High Pass Only mode. Third, ensure that the switch located on the amp is is LP (low pass) mode and that you turn down the frequency control on the amp to somewhere around 80 or below. If none of those things are doing the job then you need to ensure that you have grounded the amp securely with it's own ground (not with a factory bolt or screw) on the floor of the vehicle. Scrape away any paint and use a self tapping bolt without over-tightening it. Also ensure that your power lead at the battery is tight as can be and that the connection is clean. Hope this at least helps determine if the amp is at fault or not. Good Luck! Dan

Signal getting to and from the Amp is problematic, if you do not have the correct wiring that will carry the necessary power then you are never going to get the sound you are looking for. Start with testing the AMP and then Wires....
u could just not have enough battery power or the load on the amp is to much. if the amp is in stereo mode it should work but if it is in bridge mode the ohms would be to low .. best thing is to get a sub amp with a 1 ohm stable capacity.. and you amp should be at least one third more powerful than the subs..eg: if the 2 subs is 1000 w each the the amp should be 2500 rms and up to prevent the amp from maxing out and over heating etc.
Sounds like blown subs, in the process of completely dying out, or a loose wire, possibly inside the box or from the box to the amp. Have your subs tested at a sound shop, or using a multi-meter, check for resistance across the sub terminals. An open line indicates a blown sub.
No such thing as a typical sub system. Be more specific? If the subs are moving well and just not basing you will need to check 2 things first. Try the polatity of the speakers (reverse one) they may be out of phase and will cause the bass to cancel eachother. Another cause is the box may the incorrect size for the speakers and will not give you the correct sound the speakers are capable of. If neither of those work check your amp settings and make sure its set on sub/low frequency.
hi, your amp seems to be getting power but the cables might be wrong so it's not getting enough power. the light on the amp should be green if everything is going well.
are you sure the cables are suitable for your amp?
