ive got a 92 SC300 i bought a couple months ago. it has the stock pioneer unit in it and a month after i bought it the passenger side speakers went out......than a month later (bout two weeks ago) the drivers side went out. i can still here the bass from the radio on the sub but none of the other speakers come on. rarely the driver side will come on than go back out. any idea how to fix it? or am i better off just buying a new aftermarket deck?

Please help ASAP

thanks!!
