For $45 amp I didn't really expect too much of it... Thanks for your advise will give it a go with another amp in the next few days

 

U have a bad head unit preouts.

 

purchasing quality car audio will go along way , especially if you have a weak link inside your system it will bring your entire system down

 

On this note, if the amp ends up being the problem and your going to replace it, be sure to look at a marine grade amp. Marine amps are designed for your application, I have personally installed them and they work well. Here are some marine audio manufactorers to look at, Wetsounds, MTX, Fusion, Bazooka, to name a few.

 

$300 an expert installation and high quality amp later... The buzz is gone haha and much better sound quality too
