Ok, I havent had my sub hooked in awhile. I kind of miss it. So one day I was hooking it up, the amp came on and everything but there was no boom boom ? What could be the problem. Could it be the RCA jacks or the remote wire. I also got a new amp its a 650 watt Sony Xplode. Help me out guys.

its not the remote or else the amp wouldnt turn on, it could be any number of things. either the sub or the amp, if the amp is new, its probably the sub. check the Impedance of the voice coils, Id bet they are blown. where did the sub sit while it was out of your car?

um, do this man, go to like auto zone and buy like a 15 or 20 dollar Digital Multi Meter. and you set it to the ohms section, most likely your mm will be only capable of down to 20 or so. you hook it up to the box. If you have a single 4 ohm voice coil sub, the sub should read anywhere from 3.5 up to 4.3 average. If its a dual 4 ohm sub you could see anywhere from 1.7 up to 2.4 or 7.6 to 8.3 ohms. Depending on the way its wired.
You can also check the rca's. by taking the two little probes putting one probe on the center spike of the rca's and the second probe on the sheet that looks like a guide to the outside sheild of the same rca. and put your mm on voltage. If you are getting a 0 voltage then your rca's could be bad.
if the amp cuts on, then your problem is in the signal transfer ie, rca outputs on the hu are blown, or the rca's are bad, or the speaker wire from the amp to the sub box isn't connected or bad, or the wire inside the box is bad/blown, Or the subs themselves could be blown.
A digital Multi-meter is a must have. I have a buddy who lives down in columbus who is An Audio guru... send me a pm, I'll transfer that info to him and have him call you. He may charge you like 15 bucks to trouble shoot or he may have you roll into his/his buddies shop idk but he is local to you, and very well known in the car audio world!

Another simple reason could be when the speaker wire was placed into the terminals on the enclosure and/or sub, the wire was pushed too far in and the wire is not making contact. I see this on consumer installed systems an average of 2 times a month.
