just trying to figure out the best way to tune my amp and sub and which way to wire it 4ohm or 2 ohm load i have a diagram somewhere but cant find it.... ive had a couple systems but still dont know about the load and wiring call me a noob...



this is my new amp. its a pioneer class d gm-d8400m i got it for cheap so i cant go wrong really

I would wire them like the 2nd diagram. So you get a final ohm load of 2 ohms and would get atleast 300w a piece for the 15's.

I don't think the amp is a good match. Your speaker will only get 300 watts RMS @ 4 ohms, unless you plan on running the amp @ 1 ohm (I wouldn't).

I think he is only running one sub.

That is not a very thought out combination.

Yep get another sub, or buy another amp sorry.

Only 1ohm or 4 ohm loads are possible.

You can wire it up for a 4 ohm load, but its not alot of power going to it.

BUT........... I have 300rms going to 2 18s, they are also in a 12 cubic foot enclosure and tuned to 30hz, so technically it doesnt need a ton of power.

(realy I bridged my RF 450.4 to a 2ohm load and it works, shoutout to RF for build quality because your not supposed to do that, ) I wouldnt do that though, it can and most likely will destroy the amp eventually.

Dont do as I do, do as I say lol.

Your amp is more than likely shutting off because it's going into protect. The amp is NOT designed to run at 1 ohm. You are going to destroy that amp.

I don't think the bass knob will do anything. That amp isn't made to take 1 ohm like subsonic said. But if you keep your voltage up and go easy on the gain setting you might be able to get away with it, just hope you have enough box rise.

You are past special running that amp at 1 ohm. Could have used those $60 to buy something that could actually work for you.

WOW, you dont listen very well. :(

Dont try to say I did it, mine works, and works fine.

If your amps shutting off (protect mode) you cant run it like that period.

Buy another sub, or toss the amp.

I dont care if the amp is free, it isnt worth not being able to listen to what you invested in.
