I hope this makes sense
I have a 2006 Jeep Wrangler with the stock 7 speaker system. I has a crappy subwoofer between the front seats and a little amp. My subwoofer blew out from what I consider moderate use so this is my question.
The factory speaker is a DVC eacj with 2 ohms looking into the speak and the amp it comes with has two independent inputs into the speaker, one to each coil. Can the DVC be replaced with a 2 ohm SVC that can handle at least double the watts and hook both of the old positives to the SVC positive and both the old negatives to the SVC negative since from the amp looking to the speaker is still going to be 2 ohms.
It makes sense to me but can be completely wrong. thanks for the help
No, you can't do that. If you use a SVC speaker, you will only be able to use one amplifier channel.

Support the12volt.comJust out of curiosity, what would be the effect of wiring it in that fashion. I'm asking because this is apparently a pretty common problem with the jeep's system and the only subwoofer replacement people have found is a kicker 6.5 SVC without replaceing the amp and taking up what little space there is in a jeep and people have posted that they sautered the two negatives and the two posistives together with a good result on the 2 ohm subwoofer. I do believe the people that have done this didn't quite know what they were doing though.
Wiring two amplifier channels together will most likely blow both amplifier channels, assuming it really is a 2-channel amp. If they have done this and it worked then most likely it is not a 2-channel amp, it is a mono amp.

Support the12volt.comThanks for the info. I'm not sure if it really is a 2 channel amp. But from standard resistance reading none of the circuits seem to be in pararllel or series.
Sorry If the question was ridiculous, It's just that I'm an electrical engineer, and it seemed to me that if two independent and equal sources feed two independent and equal loads (balanced system) you could have combined the ciruit loads from the independent sources as long as the load was current (or power) rated suficiently high enough to pass (absorb) the source current (power) from both sources. Where I'm not experienced is the internal workings of amps and if it has buffer stages or other types of isolation circuits that would prevent one source from feeding the other through the load in an unbalanced situation.
If you have any comments please let me know. Thanks again for the info, I really do appreciate the help. I hope my above parargraph didn't seem like I didn't believe you, it was just my reasoning that might explain the success stories.
I am not sure about the Infinity amplifiers, but it being a 2 ohm driver I am sure they do as they do it on the Bose systems. If you have a low impedance woofer you can achieve decent power from an amplifier without building a switching power supply. This saves them money. Without a power supply they use basically the same technology used in high power output chips in the newer radios. There is signal on both the positive and negative wires. They are 180 degrees out of phase. If you check the speaker wires with a meter, they show no connection to any other speaker wires. So if you say they do not appear to be paralleled or in series with the others, this is probably the case. And as stated earlier DO NOT connect both sets of speaker wires together.
Thanks for the info on what's going on in there.
