Have a question for an amp i just bought.
Ok i bought this amp for my 2 10" rockard 4ohm p1s
http://www.sonicelectronix.com/item_...KAC-7204.html#
amp specs so its easy
2-Channel Class AB Car Amplifier
RMS Power Rating:
4 ohms: 170 watts x 2 chan.
2 ohms: 250 watts x 2 chan.
Bridged, 4 ohms: 500 watts x 1 chan.
Max power output: 500 watts x 2 chan.
sub specs
10" Single 4 ohms Punch Stage 1 Subwoofer
Power Handling:
Peak: 300 watts
RMS: 150 watts
Now when i get my amp and i hook up my subs as long as i connect positive and negative on each sub the amp will be in 4ohm mode right?
Say i wanna buy 2 10" 2ohm 250 watt rms subs now how the heck do i connect them to the amp cause the amp is rate at 1000 watt peak 170 watt rms at 4ohm @ 2 channel and 250 watt rms at 3ohm @ 2 channel and 500 watt rms @ 1 channel can someone please explain to me how i know wether its
cause i plan on buing 2 2ohm subs rated at 250 rms or so and need to know how to hook them up thanks
10 views no response i guess this is a tough question lol

What?!
Dud, the way you wire up the amps determines the change to their rated Ohm rating. Your Ohms are your resistance to flow. If you wire up the R+&- to one sub and the L+&- to the other sub, you will be at the subs rated Ohms. This is assuming you have SVC speakers, which I don't believe likely since I haven't come across a SVC 2ohm speaker yet. If you are getting DVC, then remember that Parallel halfs and Series doubles effective Ohms.
Your best bet would be to buy two 4ohm DVC speakers and wire each of them in a parallel setup on it's own channel. That would put you at a 2ohm load one each of the two channels.
Damn bro, give me a chance to at least finish typing...

Your woofers are rater at 150 rms @4ohms, forget that peak sh*t, its all about the marketing, RMS is the only one you need to worry about.
Your amp is 170x2 @ 4ohms, that lines up pretty good.
Now if you follow this rule you should be fine, the woofers you hook up the lower the impedance. This also applies to voice coils, think of a voice coil as a whole other sub.
Now if you want to run in 2 channel mode @ 2ohms to get the full 250 watts out of your amp then you need to buy 2 DVC subs
1SVC sub =4ohm load
2SVC subs=2ohm load
4SVC subs =1ohm load
(this is all per chanell)
So the same would be true with this
1DVC sub=2ohm load
2DVC subs =1ohm load
(once again per chanell)
I hope this helps you out, I know its a little confusing at first but once you get the formula down, it will be like second nature.
If you still have questions just ask.

ok my amp instructions says to bridge my amp to wire to connect the R + and L- and DO L+ and R- for the other sub that sound right to bridge at 250 rms @ 2 channel?

So if i bought 2 Dual voice coil 2 ohm subs would i wire them how to get my full 250 watt rms
connect how

If you bridge it, it will only have 1 effective channel. As I said, your better off picking up a pair of 4ohm DVC subs and wiring them up in Parallel on their own channel. That will give you a 2ohm load on each channel, plus allow you to keep right and left channels, if you care about stereo bass.

Just stop man. Your going to give him bad advice and he'll end up wiring his stuff wrong and blowing something. Wiring in Parallel as I said will half the effective Ohm. Wiring in Series will actually double it. Hell, if you take two 2ohm DVC subs and wire them completely in Series, you'll end up with 16ohm of resistance.

Here, this is how you would wire each sub if you get two DVC 4ohm subs. Make sure you wire one of them on right and the other on left as shown in the first diagram.

That will give you a 2ohm load on the right channel to one sub and a 2ohm load on the left channel to the other sub.

Who said anything about wiring in series
Just double the wires up
From the positive and negitive on your left side,run one set of wire to the one of the inputs on the the sub, Pos to Pos Neg to Neg, then piggy back the wires from one voice coil to another Pos to Pos, Neg to Neg. Do the same for the right side
Parallel wiring, this will allow you to run a DVC in a 2ohm load (per channel om your amp)
BTW Your diagram is exactly what I said to do so I don't understand how you can say I'm giving bad advice then say to do the same thing and call it good advice
WTF?

If you don't want stereo bass and would rather have mono, then you would want to the two speakers together as shown in the second diagram on this page.
http://www.the12volt.com/caraudio/wo...s.asp?Q=2&I=42
This will get you a 4ohm speaker load on your 4ohm minimum bridged amp. Just make sure you wire your amp up right for bridged output, which is normally a positive on one channel and a negative on the other, plus a switch or knob turned to a certain area.
Personally I hate running an amp in bridged. I'll buy a mono amp if I only want a single channel.

guys stop arguing its retarted... P1s are only single 4 ohm or single 8 ohm . So if u have a single terminal on the box that says 4 ohm then u hook up the single terminal to a single channel on the amp and be sad u only get half power... (or u can hook it up bridged and possibly blow the subs) If you have 2 terminals hook each individual terminal to an individual amp and still be sad u have half power
Correct answer to the question is the amp and subs dont mix. Buy 2 DVC 4 ohm subs rated at 250w rms and be happy

now using that diagram there i noticed it only connects at one end so i would only connect one end of my box and which terminals would i use and will that give me 2ohm at 250 watt rms at 2 channel it dont make sense to me for my amp

ok so why does my amp say 250 watt RMS at 2 channel how do i wire it for that because if i bridge it with R+ and L- then that is my 500 watt rms at 1 channel
never mind found it on rockard fosgate site thanks guys i appriciate all the help

Well you have a choice. Your amp can put out 250w x2 @ 2ohm, or 500w@4ohm bridged. The first way will be stereo and the second mono. Most music does not have stereo bass, but it sounds a lot better in the music that has it. However, you'll need a box with split air space for it to sound its best.
When wiring up the speakers, which ever of the two ways above you go, you need to wire the two voice coils on each sub in parallel. From there, it would be hook up each channel to one of the subs for the stereo 250w x2 @ 2ohm -or- wire the two subs together in series if you went with the bridged option. Since ether way, your amp would be pushing ~ the same effective power they will each be about the same volume.
