 Subject: Sub wiring and watts

Message:
Hello, It seems that i have a question to ask so can someone help me. i want to learn concepts before i go anything. Anyway.
Lets say that i Have 2 Dual voice coil subs at 4 ohm wired in series, the result will be 4 ohm impedence rite?
If my amp was 300 watt at 4 ohm does each speaker get 300 or does it get 150 each.
Lastly If the sub is Dual Voice Coil am i allowed to use just one end so it will be like a Single and get it 2 ohms
Thanks everyone

- How many ohms are the VC themselves? 2 ohm? If so then each sub can be wired to either a 1 or 4 ohms load. Then the TWO subs wired together can be a total of a 2 or 8 ohm load back at the amp.
The Kicker, Rockford, JL and Crutchfield websites have wiring digrams to show you the various combinations, check those sites to learn how it's done. Multiple DVC subs can get confusing to the new commer.

- The amps power is always divided among the subs (and/or VCs). So at 300 watts into two subs = 150 a sub. If they are DVC subs then it's 75 a coil which is still 150 a sub... provide all your ohm loads are correct (see above). FYI almost everyone rates DVC subs as total power not per coil, so don't worry about how much power each coil really gets in the end.

- NO! You must always use BOTH coils. You'll mess the sub up big time if you only use one coil :o Repeat use both coils or kiss the sub good bye :(

If each voice coil is 4 ohm each then you can make each speaker 2 ohm. If they are 2 ohm then you can get a total of 2 ohms if you wire them is a series-parallel configuration. It sounds like you have a 2-channel amp, if so, either will work. This is a way to do series-parallel-
Wire each sub in parallel (pos+pos/neg+neg). Then make a positive and negative lead off of each sub. Connect the pos+ from one sub to the neg- of the other. The two remaining leads (one from each sub) connect to your amp.
