I want to wire 4 single voice coil amps like shown above
all 4 ohms
Just want to get a second opinion on if this is safe for the subs and amp.
I think it is, I just want second opinions.
Two speakers are rated 500 max and the other two 600.
RMS is like 150 or so on these.
Thanks for the input
Here is the Manual for my amp:

I got that two,
but it looks like this is made for a mono amp
Will the second setup still provide a 4 ohm load on the amp if I use it on my amp bridged?
Basically I'm aiming for 4 subs on either 1 or 2 channels with a 4 ohm load.
google "rockford fosgate wiring wizard". it has all wiring options for subs,amps etc.

I'm running a single subwoofer setup and the only way I can explain my problem is to put it in these terms but i repeat I only have one subwoofer. Say if I had two subwoofers what it sounds like is if one of the subwoofers stopped hitting at mid to high volume leaving me with less bass output after a couple minutes. I first suspected the amp was going into some protection mode because it was heating up but I called alpine support and later confirmed that the amp doesn't do this if it overheats or gets overloaded it will simply shut off completely rather then lower output. I was instructed to check voltage at the battery and compare it to that at the amplifier to check for a bad ground and I did comfirm the voltages matched. And I am running 4 gauge wire to the amp so that is not a problem. I'm just kind of stumped since I have two other possibilities of failure of the headunit or the subwoofer. The pioneer primier subwoofer has two 4 ohm voice coils wired parallel and when I check the final resistance I get 2.4 ohms. My idea is that one of the voice coils is damaged and I loose some power to my subwoofer intermittenly as a result. But then I was thinking what if the headunit for some reason is overheating and sending low output through the preouts causing my problem. Any ideas or things to look at before I waste money trying to replace either one. By the way the headunit is also a pioneer primier I don't recall the model though.
Well it turns out my subwoofer is the problem and I wanted to say the reason I wired my car with 4 gauge wire is for future upgrades its only smart to wire your car once and not have to go in there and tear it all out when I make a future upgrade so its not pointless its a smart thing to do if you plan on keeping the car.
Sounds like you might need a capacitor or possibly a larger alternator to handle the load the amp is pulling.
