car stereo problem!!

so i thought i'd blown my rear speakers 6x9's - as they sounded well off.

I bought a new pair and stuck them in. Now these are new 6x9 meant to be very bassy and the like.

They sound extremely tinny. On messing about with the settings, if i alter the balance and the fade so that all the output is going to one rear speaker it sounds OK - ish.

i'm therefore wondering if it's a problem with the actual head unit (a 3year old Sony Mp3 unit)

any thoughts?

Polarity is wrong - make sure they are wired up correctly

do you have a amp?

i tried switching it round so positive was negative, and vice versa = no change

strangely the speakers in the front sound normal, loud and bassy.

no amp - just the head unit - a sony with a 50w p/c MOSFET

fiddled again - it's all fine - though the speakers aren't amazing!

get a amp in there, will sound SO MUCH better!

Then HU probably cant deliver suffient power to get the speakers moving properly. As stated get an amp and it will sound better. The HU rating will be PMPO and not RMS. RMS is probably circa 15-20W.
