im a noob with car sound so dont judge haha..

i connected the 2 JBL speakers to the amp but i get distortion even on a very low sound level someone told me its becoz my amp is to powerful for my speakers. my idea is to connect 2 more 6x9s i havent bought them yet i want to know witch will be best for my setup ?? and if i connect all 4 speakers to the amp by bridge them will it make the distortion on my front speakers go away or what do you guys think is causing that plz help ?

Hi.
I was wondering if you could comment om the head unit you have: ice imv-7000dd. I am concedering purchasing it but i cannot find any reviews on the product online. Thanx. J

Try turning the gain control knob on the amplifier to the minimum setting.

first of all, NO. an amp cant be to powerfull for your speakers and cause distortion. Just lower the volume!
You dont provide much more info. It will be difficult to diagnose. what kind of distortion? are they mounted in the doors already? do you have bass turned way up?
