Just put in front facing kicker subs & a kenwood marine receiver in my 2005 roadster and now when I turn up the base I get quite a raddle maybe I have to put some sound deadener on the bare metal in behind the subs ? The subs are clear of any thing touching them.

 

Raddle? I am going to assume you mean rattle.

I'd ask you "what is rattling"? Front facing speakers tend to sound very good in Crossfires. I know of one lady who put front facing, surface mount speakers behind her seats (using the cavities provided for the factory speakers) and her's sound really good. So, is it a 'rattle'? Or is it a distortion in the speaker- that is, are you driving the speaker too hard or perhaps driving the amp too hard?

 

It sounds like a rattle but you might be wright on driving the amp to hard I did not thing about that I might have to run new wires from head to subs . I might put the stock unit in and see if the rattle is still there.

Thanks

 

If you are driving the speakers too hard, new wires won't help. What will help is not driving the speakers so hard or putting in speakers than can take what you are doing.
The idea that large diameter wires are needed for short speaker leads in a car is simply wrong. 100 watts peak power across 4 ohms is only 5 amps; no need for "monster cables" there.
(Altho if your wires have been wet and you have corrosion in the terminals at either end - then sure, replace THOSE wires.)

Sorry I am going to run wright from the head unit for the subs not through the amp so I have a setting on the new head for the subs so I dont drive them so hard I hope.
I am still learning after all these years Thanks for the help.

 

I would not do that, the amp is four channels. Do this:

All ya gotta do is add four wires from the head to the amp and cut four jumpers at the amp. That gives you four channels and you can use the fader to balance front to rear..

 

Found my rattle the carpet beside the speaker when the base hits hard will vibrate on the metal behind it. The front facing kickers when turned up you can feel it in the back of the seat working great with some padding in that spot.

 

Just did the 4 chann



el amp wire for the subs from my new kenwood went right from the rca sub ports to the wires going into the amp the hard part is to get the wright pin number to wire color. no pin numbers on the plug just wire colors on back
