stumped 4 ohm bridged
Trying to wire the tn4.900 amp into 4 ohm bridged mode. Have the 4 each TS-D6902R pioneers. Wanna do two per bridged channel for the 450 watts times 2 at 4 ohm. Got the wire running out of the R+ and L- on the amp. How do I hook these 4 ohms speakers together to present a 4 ohm load on the amp. Series presents an 8 ohm load. Parallel presents a 2 ohm load. Can't find anything showing how to run them to present 4 ohm load at amp. Thanks fellas.

Eshaw- Bridging that amp brings it down to two channels? I would think you would want to run your speakers in parallel and bring the impedance down to 2 ohms using all four channels? That will give each speaker about 115 watts if my math is correct.
Edit: Sorry Eshaw . . looking at your post again I misunderstood what you were saying. I thought you were attempting to wire ALL of your speakers to the TN4.900. on second look you just want to wire the 4 pioneers. . Correct? If that's the case 150 watts to each speaker is plenty.

cannot do... unless you are going to use power resistors.
bridged @ 2 ohm no good.
run 1 speaker at each channel, as Gannicus mentioned.
or change out speakers to 2 ohms (like the JBL's I got), and then in series...

That's what I was thinking. For some reason 150 watts per speaker still isn't giving me the thump I used to have when I ran the arc ks125.4 and had two pioneers per channel. They were only getting like 63.5 watts but they were thumping way harder.

Hmmm I'm running 4 pioneers in the saddle bags with the TN4.900 and my speakers are shaking the ground. But I'm running the Old School TS-D901P revs that go down to 22hz.

Oh no. . Not that! Just take your time brother and make sure all your connections are right, gains set correctly and tune it from the HU. Those speakers will wake up. Trust me. You got the right amp.
