I have a Bazooka subs/box/amp combo. they are 2 10" subs in ported box with 300w amp. Circuit City installed them roughly 14 months ago. They used to hit extremely good in my stang but lately they sound non existent. Anyone have any ideas why this has happened????


thanks

 

First question is are both subs working and is everything powering on?

 

yeah there is power to them. I think I may have figured it out. But what were you going to say?

 

Sometimes the easiest and most obvious are what happens and with subs the connections sometimes come loose or the amp has a loose connection somewhere. Check the wires going between the amp and subs and usually something came loose/ Sometimes the fuses like to blow also.

 

as he said start simple. Check power connection both power and ground. They should be tight and not have any wiggle room.

 

This reminds me of my kickers when one sub hit like a **** and the other was like the bastard child. I played wit my HU nothing...Then borrowed a friends amp and it was the same thing. Hooked my friends subs to my amp and they both hit hard....I was confused as hell. I then checked voltage to speakers and they were the same.....All you can see me do is have the biggest confused face on....Then I had the smartest idea check the wiring in the box since my solobarics are dual voice coiled I decided to...to my amazement one of the wires came loose and I was like damn I wasted two hours on a simple connection

 

had same problem where my amp had power but weren't "hitting" problem was a loose ground connected to my amp but check all grounds

 

allright sounds like that may be it

 

After installing and troubleshooting many systems it is amazing how often it just comes down to a loose wire or a connection that was just barely almost good and how you can find them.

My first freshmen year(yes first) I was in tech school and we were building a circuit to test the lecture we just had. Two rowes behind me one of the guys raised his hand and told the instructor that his signal generator didn't seem to be working right. The teacher asked him a couple of questions and agree from his desk that it sounded bad, and as the teacher started to get up you could hear the student behind me start to "bump" the generator with his hand. After two bumps it turned into a slap, and after two slaps he then announced he fixed it. The teacher told us all to stop and pay attention as he had just showed us an important lesson called the "techincal tap", and told us that we would be suprised how often we could bill someone for that.

Since that day I have been using a similar method to isolate bad connections. All connections should be strong enough to put up to a good solid pull on the wires, and a good solid pull should not pull anything apart. I will start by simply wiggling the connection, then lightly pulling on it and the work up so my foot is between me and the wires and I am pulling with all my weight while sweat pours off my head . Then I go on to the taps. I start by tapping the top of my fingers on the suspected bad item, then go lightly knocking with my 2nd knuckle, then to full blown knocking with my fist, then onto a full blown puch and again onto a 16 lb sledge hammer . For boxes I will often just turn them so the subs face a different direction to see if there is something loose in the box.
