If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...

Wire up two 4 Ohm subs in parallel (bridged) or one 2 Ohm sub.
You will take both of your subs positive leads and run them to the left positive (white connector on the amp) and both of your subs negative leads and run them both to the right negative (gray and black connector on the amp). That's max RMS right there. Pay attention to the Ohm rating of your subs as this does play a factor. What I explained is how to bridge two 4 Ohm subs. 8 Ohm is a little different but car subs rarely are 8 Ohm.

make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.
My recommendation is to get a line level converter. Go to a car audio shop or even best buy and specifically ask for a line level converter. It will have speaker wires in and RCAs out. Connect the speaker wires to the sub woofer speaker wires and then you will have the RCAs to run to your amp. I hope this helped.
unplug all speakers and see if it still into protect .If unit powers up normally without speakers , then hook up a temporary speaker directly to speaker out to see if you have output.If it works .Then check speaker cables and speakers for shorts.Also make sure you have good ground and main power and standy are present.
A: make sure that speakers size and watts.B: Type of speakers is used for base. C: Make sure the current (Amps)of the battery and your amplifier. D: Check audio from source and decrease the level of base.
