Folks, I have a 1996 Suburban ( K2500 ) and to cut a long story short, I've decided to keep it and want to make it as comfortable on the inside as I can. Audio is poor. THe rear subwoofers dont work, and the front door speakers just about function. So. I'm on teh hunt for a decent set - front door speakers and rear subwoofers. Want a good quality sound. I usually wire up my iphone via FM Transmitter thorugh the standard head unit to play music / interent radio / podcasts. Head unit works ok. Any suggestions on a particalur brand of speakers that woudl work well in a Suburban? Don't to shell out loads of cash, just a good clear crisp sound with good bass. Thanks in advance.
