My advice is to add some bass blockers to the rear speakers. These are capacitors that run inline with the positive speaker lead and provide a passive high-pass filter to your rear speakers. Depending on the size of your rear speakers, you should look for capacitors in the 250 microfarad to 133 microfarad which will give you a 6db high-pass in the 150 to 300 hz range on 4 ohm drivers. The bigger your speakers, the bigger the cap I would use, so if you have 6X9, I would look for 250 mic caps to cross around 150, if you have 6", I would look at 200 mic caps to cross around 200 HZ, 5" or smaller maybe look for some 133s to cut below 300 HZ. It is a 6db per octave slope, so it is a gradual roll off.
Thanks mate that really helped i have 6.5" speakers and i will look for 200 probably
i looked into one of them online but it says that it block the freq between 0-600 hz where the HPF block 0-80 hz !!
