Stereo & Electronics - Best way to wire my 4ohm dvc sub

I have a 2 channel amp good for 150w rms at 2 ohm or 300 bridged @4ohm I also have a 4ohm dvc sub so all i can get is 2 or 8 ohm bridged will 8 ohms lower the output? should i just wire it as two seperate speakers that would be 2 ohms correct? that way i should get 150w per voice coil. Am i assuming right or am i about to blow some Sh!t up?

At 8 ohms you are lowering the power output by half. You will still cut the power in half running a voice coil to each channel as you are wiring 4 ohms into 2 ohm channels. No matter how you do it this sub won't match up well with your amp.

What model amp is it??? What model sub is it?? Being specific about the equipment used makes it easier to help you out.

I is a 8" L7 4ohm in a small sealed box with an old MTX Blue thunder pro 1502

Here you go on that amp:
Rating at 12.5v
75 watts RMS x 2 @ 4 ohms
150 watts RMS x 2 @ 2 ohms
300 watts RMS x 1 @ 4 ohm (bridged mode)
Rating ar 14.4v
425 watts RMS x 1 @ 4 ohm (bridged mode)

That's why I asked about the amp because ratings can be deceiving. While that amp is 300watts RMS at 4ohm, that is a 12.5V rating. Most 12V systems run at about 13+ volts. So your going to get more then 300watts RMS out of that amp at 4ohms.
Most of the older amps like that are underrated.
Back to your original question you could run that amp at 8ohms and it would be running at or slightly above 150watts RMS. Try it, you may be surprised about how much bass is actually produced. Remember half the power is NOT half the output, it is a difference of about -3db. That is a cool old school amp.
Your other options are to get another amp or another sub that would more closely match each other. I would not run that amp til it blows at 2ohm because that is a collectable old school amp that someone might want. You may be able to trade someone for the right amp for you as well. Just a few options that may be useful to you!
Good luck!!

Thanks for the info man. I had it hooked up at 2 ohms to try it out . The amp never even got warm. I'll try to get another sub. I have two of those amps the 150x2 and a 50x4 I'll prob. just end up getting the sub,amp,combo you sell.

The one I sell is a matched set. It is a 1ohm stable micro amp that is 300watts RMS at 1ohm with a 2ohm per coil DVC CDT carbon fiber sub that wired in parallel is 1ohm. You also get the amp wiring kit and enclosure that is matched to that sub.
That sub you have is actually a decent sub. It's not my favorite or anything but it will put some bass out there. You really only need another amp to run it at 2ohm. Just a thought!
