Recently i've had my sub cut off after a period of time while in use. i found out that the terminal connection the inside of my speaker box to the outside was faulty so i hardwired my sub to my amp and it...


your ground should end no more then 3-4 feet from the amplifier and both your power and ground should be a minimum of 8 gauge and depends on the power consumption of the speakers you are using more power requires a thicker wire..could be from when you took it apart but its hard to say, really depends on what you did while the amp was open...

another issue could simply be that your etup doesnt have the needed power to run the system and you may need to introduce a capacitor or secondary battery, again this is will depend on your power consumption.

I have a power acoustik bamf 1600/4. not working 5 hours later


use a multimeter to see if the amp has good power wire and remote turn on voltage. then check the ground and make sure its a good strong ground. check the sub to make sure its not bad. make sure it reads whatever ohm its supposed to. anything less than 4 ohms will clip the amp if bridged. if alll that is good then the only thing left is the amp. it sounds like the power supply is bad but check everything else just to make sure. good luck.

KAC-9102d no sound, Amp powers on but no sound to the subs.


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...

Only get sound wen rca's r in halfway


You have a bad set of RCA's. Try and get a pair specifically made for car audio. There are hundreds of brands, usually the cheap ones work fine.

What usually happens is on cheap RCA cables, wires inside the actual plug split apart and short out on one another. Get another set of cables and you'll be fine.

Amp Turns on... then off


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.

My amp is only pushing the left.


Swap the RCA inputs to see if the dead channel follows the RCA input.

AMP not workin


if you saw smoke something fried, im surprised it still kicks on at all. my best advice is if you kno how to use a soldering iron, see if you can locate the problem, (i.e. melted wires and such), if not best would be to look for a new amp. hope this helps
