i really want to avoid using 2 amps.. if i just want to power the fronts and a sub.. then i will have 2 channels not in use with a 5ch amp.. is the 5th channel usually made specifically for subs? i did see a phoenix gold 5ch amp for sale in the classifieds.. maybe that will do??
You can bridge the 4 channels into 2, and run the 5th channel for the sub, and it will be wicked!!!

So as you can see, depending on which way you wire your voice coils together, you're either creating a 1 or 4 ohm load for whatever amplifier you choose to get. But I've never come across an amp that is capable of running bridged channels at 1 ohm. If there is one, I'll assume it wouldn't be cheap.

If he is planning on using that amp, he can run the sub at 4 ohms and get full power. Slash series are regulated fully, and make full power at 1.5-4.0 ohms.

thank you so much for the diagrams.. but just a bit confused as my version of the sub is D2 meaning 2ohm.. how does it turn into a 4ohm if it says its 2ohm version? If it does turn into a 4ohm then i can pretty much use any 4ch amp because most when bridged support minimum 4ohm.. correct? i noticed someone selling a phoenix gold r-9 5xchannel amp. with this amp would i be able to bridge the 4 channels and run it to my 165cv Focals and then use the 5th channel on my JL sub? assuming i have the setup like your last diagram?

The 'D' stands for "Dual". So you have two voice coils that are 2 ohms each. Wiring the voice coils gives you the 4 ohm total load. Wiring them in parallel gives you a 1 ohm load.
Yes, most amps will be capable of operating at 4 ohm when bridging channels. Like I said, there'll be some that are 1 ohm stable when bridged. They just won't be cheap.
I have to make a retraction on the Hertz amp I suggested. The HP4 is a $1500 amp. The EP4 is a $400 amp.

tragicmagic thank you for the clarification.. just noticed that you reply to alot of people questions.. you must be the audio guru lol .. big ups to you for your help!
anyone have a decent USED amp for cheap they wanna get rid off that will power my system??? only want to spend about $100.. yes i am poor right now

DJchinky, thanks. But no sir, I am not an audio guru. Just an enthusiast. To be honest, my knowledge pales in comparison to most of the guys on here. The reason I try to be so helpful is so that I can learn about all the stuff that's out there, and the most efficient way of stringing it all together. When I see a message posted by newer users, it gives me an opportunity to do some research. The more we know, the wiser we are when it comes to making a purchase. With that said, you have to listen to the equipment to find what really sounds great to you.
You'll find that some of these guys have a "go big, or go home" attitude. Just an observation. While their input and suggestions are all with good intentions, its important to realize that what they're suggesting may be a whole lot more than you're looking for.
Go around to audio shops. Start small. Then gradually listen to more powerful, higher end equipment until you reach the point that you're most satisfied with. It never hurts to buy equipment that has more capacity than what you're using it for, at first, in case you want to push your system further in the future, you'll already have some headroom.
If I were you I'd take that sub, wire it for 4 ohm, then go around hooking it up to amplifiers with different outputs at 4 ohms. You might find that a less expensive 300W amp is enough. Or you might find that you want to have 600W available for it.

Well, I think the reason a lot of guys say go big or go home, cause everyone went through many upgrades, which costs money. If you go big and expensive as soon as possible, you will save money at the end on multiple upgrades which will inevitably cost more. Experience speaks volumes. On the flip side of the coin, upgrades are half the fun.
