on 8/8/2006 As long as you are consistent in your references to other head units, Vmax is just as useful as information to know as Vrms, due to Vrms = Vmax/(the Square root of 2) or (Vmax)(.707). So as long as all the values you are looking at are all Vmax or all Vrms you will be good!

on 11/22/2005 Browse the major makers' websites and look for the kinds of features you think you want. Do NOT pay attention to the price - nobody pays the sticker price. Then, go to the stores and play around with your Internet favorites. Finally, buy the stereo ONLINE. You really can save $100-$200+ with online stores.

on 11/22/2005 Ask if the store you are purchasing the stereo from will install it and how much it will cost. Sometimes, if anyone other than a liscensed installer puts your stereo in, the warranty is voided.

on 11/22/2005 Verify that your installer has grounded the unit as the manufacturer intended. There should be a black, brown, or green (w/ yellow stripe) wire from the unit to a clean (bare metal), solid grounding point on the dash or firewall.

on 11/22/2005 Verify that your installer has properly mounted your unit. The rear of the unit should be securely supported. If it is not, the unit will bounce and vibrate ... shortening the life of the unit and possibly breaking the front mounting.
