Re: subwoofer help

You need to wire your Subs in Series. This way the current that passes through one has to pass through the other. Bridge your amp. and follow the wiring below.

Amp+ to Sub1+
Sub1- to Sub2+
Sub2- to Amp-

My subwoofers in my car are not working properly, I have a Kenwood Hu, 1000 watt 2 channel earthquake amplifier brand new, 2 Sony Xplod 10 inch subwoofers and a pioneer 12 inch subwoofer. the problem is...

I just got done with 10 others like this with the same problem, just look at some of my other solutions to see what you will be doing. Basically you need to upgrade your entire charging system to run these amps, You guys are not even considering the power draw that it takes to keep these things running at full power! You need to plan out your system way before you start to buy things to make sure that you will only have to install it once and do it correctly. It all starts with the power available from your alternator. You will have about 40 to 60 amps of left over current to use from a stock alt after it has to charge the battery and power the car while driving. That means you can have a head unit drawing 15 amps and a sub amp that will draw 35 to 40 amps before you will need to upgrade your entire charging system. Failure to do this will result in Batteries lasting 1 year a new alt every summer, your amps will burn up the insides a few times before you realize the importance of this all.

Generally the BEST places to run the wires is over head if you can. There are no wires there to cause any noise from cables or wires that are not shielded. it may be harder....but you wont have engine noises. And NEVER run the Power wires under the carpet... I have seen a car go up in flames due to that very thing. My cousin Ron was pissed! Hope I helped.

I have a Panasonic EAA046B amp connected to a Polk Momo speaker system installed on my 2006 Sea Ray boat that was factory installed. Last week when we turned on the stereo all we got was short basey thuds...

Hello, if you know how to use a volt/ohm meter and you are comfortable with taking the bottom cover off the amp I can assist you in testing a few things to narrow down the problem. The easiest way would be to talk to you on the phone if you don't mind. I own a car audio installation and amp repair shop. If you want to do it by e-mail we can do that to. I would have to walk you thru the steps, it would'nt take long. Taking the amp out and taking the cover off takes longer. Anyway let me know. It sounds like you may have a power supply problem. Or, it could be a few other components inside. It's hard to say without doing the test that I would help you with first. Cause the amp is coming on but you say with some thumps coming from sub and nothing from the other speakers. It maybe doing the same on the other speakers but because there are crossovers on them it would cut off that low frequecy noise. You could also maybe have some shorted output transistors but like I said, have to do thaqt initial test first if your up to it. Send me a private message so I can get your info or i'll give you mine to decide what you want to do.

Amp Issues

1) Make sure a bridged load of no less than 4 ohms is applied.
2) make sure both the left & right channels are working.

Is it good

If you are using a GM-7200 amp, it should sound great. Both the amp and the subs are rated at 800 watts so be careful not to overload the bass by turning them on full power. It is good practice to have a slightly lower watt amp than the subwoofers. If you can power your rear speakers from the amp, that would take away some power to prevent the subs from overloading. Overall, you should get a nice THUMP!!
