Posted March 27, 201312 yr can someone send me the link to the website that u just plug in the numbers for amps subs and impedance's...i feel really handicaped right now i cant find it anywere thanks
March 27, 201312 yr Author thank you! is there one that u can put multiple channels into the equation Edited March 27, 201312 yr by 1two3
March 27, 201312 yr Your head unit manual should have those. http://www.hifisoundconnection.com/Shop/Control/fp/SFV/30046/view_page/Amplifier_Types_2-Channel_4-Channel_Mono_Multi-Channel Edited March 27, 201312 yr by pmureika
March 27, 201312 yr Author im looking to wire a 2 channel to my 4 door speakers at 4 ohms. correct me if im wrong. each speaker gets its own pos and neg directly to the amp and right side gets one channel and left the other?

Referring to channels 1&2 and channels 3&4 wouldn't that be a 4 channel amp? I have a 2 channel
March 28, 201312 yr Author Bc two 4 ohm speakers are 8 ohm seriesed or 2 ohm parallel.That blows...so would a 4 channel work on 4 ohms for 4 speakers?
March 28, 201312 yr Yes. But if you currently have the two channel try that first it might be plenty enough power at 8 ohms.
March 28, 201312 yr What speakers do you have? What amplifier do you have? If the amplifier is 2ohm stereo stable then you could simply wire them in series to the amplifier. You would lose front/rear fade, which you would retain if you went with a 4-channel amp instead. Depends on your goals and budget.
March 28, 201312 yr Author Goals for now just amp them and budget is already spent on the 2 channel but I could swap it for the 4...hasent arrived yet Edited March 28, 201312 yr by 1two3

I got a fosgate t400.2 in the mail but I can return it for the .4All speakers are 4ohm stable.Really don't know what to do now

Depends on your goals and budget.Pretty sure that Impious did answer your question and solve the problem. You said you had spent your budget, and you COULD swap to four channel after paying restocking fees, but try what you have with how they have told you to do it bro. These guys would not steer you wrong, I put my word on that.

These guys would not steer you wrong, I put my word on that.I appreciate the help but I don't see the answer in there. The amp is 2ohm stable but my speakers are only 4ohm stable so wouldn't that destroy the speakers?And the amp gives out about 160 per channel (this is the 2 channel) at 4 ohms divide that by 2 gives u 80/speaker. But only way I see to wire that amp is 2 or 8 ohms And id like to have about 80rms. and I don't think I would get that at 8.So the only option I see is to swap foot the .4 but I still don't know how to wire that to 4 ohms.Really confused :/
March 30, 201312 yr Author Figured out to wire a .4 to 4ohms but still don't know if its safe to run at 2ohms on a 4 ohm speaker. Anyone know what could go wrong? Edited March 30, 201312 yr by 1two3
March 30, 201312 yr You are not understanding. The speakers are 4ohm. You don't change that. You can't change that. For the 2-channel amplifier you wire the speakers TOGETHER in parallel (both left on one channel, both right on the other channel), and the amp will "see" a 2ohm load because there are two 4ohm speakers in parallel and that presents a 2ohm load to the amplifier. As long as the amplifier is 2ohm stable, then nothing bad will happen. Each speaker will receive half of the power. So if the amp does 160w @ 2ohm, each speaker would receive 80w (I have no idea how much your amplifier outputs @ 2ohm, don't have time to look it up).

See I thought that the speakers and amp have to have the same resistance, but now this is starting to make more sence to me. Electrical really isn't my strong suit.Appreciate the help guys!Will not be returning the amp...I could care less about front to rear fade.It gives out about 240/channel at 2 ohms so 120/speaker
