Hey guys,

Just a question regarding tuning my amp/sub. From the front seat I have the amp turned up high and it sounds great from the front seats, but in the back it droans a bit. With the amp turned down in the back seats it sounds great but very quiet in the front. The amp I have is 580w and im not 100% sure on the sub as it was second hand. Am I up for a newer more powerful sub or amp to get a clearer sound? Its running off a line out converter.

I can rule out it being the box because ive had it in 3 different boxes and its sounded the same each time.

To tune an amp properly you need to have the input voltage sensitivity on the amp to suit your head unit.

Depending on what head unit you have( guessing you don't have a line driver) it should be set between 1 and 3 volts.

Then you need to set low level frequencie cut off. ( guessing your sub is a cheap unit and you have a universal box) it Gould be set around 80hz, however If you have a ported box that gets thrown out of the equation.

Then you need to set te higher frequencie cut off. Guessing the same as above it shouldn't be anymore than 300hz but normally used to adjust this to suit what bass the the customer enjoyed. I they preferred deeper bass then you set it lower to around 200hz if they prefer higher frequency punchy bass then you can set it to around 400 even 500hz if the the sub is capable of it.

Lastly you need to make sure the amp is switched to the low pass filter setting.

That should Give you the sound the sub is supposed to make.

But keep in mind there is a huge amount of variables involved as to what noise you get.

Sub size. Sub direction. Sub orientation. Box size. Box type. Box construction and Ofcourse the quality of the gear you have.

Hope that helped mate

Wow thanks for the detailed answer. I'm unsure if any of that's possible with a factory head unit is it?

It's all good. All those settings are on your amplifier mate
