Replaced stock speakers. no bass??

Question

i replaced my rear 6x9s with sony xplod 6x9s. There isnt any bass if the balance and fade are at neutral. However, if i turn it to just one 6x9, there is tons of bass. but if i just put it on the 6x9s alone, there isnt bass. Did i do something wrong or is mmy stock deck designed to do that?

Answer 1

Your original factory radio is designed for those speakers the old speakers you took out are probably on 25 watts rms a piece.  When you put the new ones in they are probably around what 75 watt rms a piece so your factory radio is not going to be able to push those new speakers.  You might want to consider getting an amp to hook up in the trunk for those speakers and leave the front speakers on the factory radio  hope this helps.

Answer 2

best thing to do is take it to a car audio shop... and have them fix it

Answer 3

What you've described is the classic test to see if a pair of speakers are wired correctly in phase with each other.  Yours are not.  Go to the trunk and reverse the (+) and (-) connections on ONE of the two speakers.  That should fix your problem immediately.

If you have a GM vehicle, the (+) wire on the left speaker should be brown, and the (+) wire on the right speaker should be dark blue.
