Common Amplifier Problems
A Word about Common Amplifier Problems:
Vibration can cause cracks in the circuit boards, and will break cold-solder joints. Also, if you do not firmly mount the amplifier, bouncing around in the trunk/under the seat, can cause these problems.
Most common problem of all, with ALL amplifiers, will be burned up MOSFET's. It's not the MOSFET's fault, though... Improper "loading" of the amplifier will cause overheating, and the protection circuit in most amplifiers doesn't stop the amplifier at all or way too late to save the MOSFET's from sudden death from overheating. Running too many speakers on a single channel or a bridged channel of the amplifier quickly heats up the MOSFET's, and can result in lots of nasty smelling smoke coming from your amplifier in some cases.
READ YOUR AMP's OWNERS MANUAL! If it states you can only wire two 4 ohm speakers per channel, do not wire more than 2 4 ohm speakers per channel. Or if it says no more than one 4 ohm speaker in bridged mode, then follow the manuals recommendations.
Got Dual-Voicecoil Subs? Learn how to wire in series. Not sure how many "Ohms" you have. Go to Wal-Mart, and buy a $10 volt-ohmmeter. Read the instructions, learn how to use it. You will be glad you did.
Want to run at 1 Ohm or .5 Ohms? Get a better amplifier. Most amplifiers on the market today are not designed to run at lower than 2 ohms. Even if they state "1 Ohm Stable" on the amplifier or in the manual. It is a gimmick to get you to BUY it. For information on determining whether your amp can actually handle 1 ohm or .5 ohms loads, email me sales@db-r.com.
