hey mate if they deff have power and fuses are ok, id check the remote wire to see if it is connected and make sure it is connected all the way back to deck if not that have it checked out to see if it is faulty, that is if u are sure there is power getting to it

Just got 2 amps installed today but one of em isnt turning on?

its all wired in correctly, all of the fuses are in tact, everything was professionally installed.

any ideas?

Join a wire between the 12V and the REMOTE wire at the terminals on the amp and see if it turns on, if not check the earth on the body from the amp. If you have 12V at mains and remote and earth and it still doesnt turn on check the fuse on the side of the amp, if still no go take the amp back under warranty.

P.S Best to check with a test light.

I'd say it's better to check with a multimeter as it shows polarity. Also the test lamp will light up at voltages under 12V, whereas the multimeter will tell you the voltage.

I had a very similar problem.

First (as said before) test voltage between negative wire and positive wire (should be 12V), then test between negative wire and remote wire (should be 12V). If that looks okay, connect the wires to the amp terminals. Amp still not turning on... Now test the voltage at the terminals of the amp with the wires connected. I ended up with only 7Volts between the negative terminal and positive terminal/remote terminal.

The problem was a bad connection between the negative wire and the car body, fixed by using a different position and making sure i cleaned the surfaces properly.

      Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?

      https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild.

      Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself.    N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.

      Running rich in conditions where it shouldn't probably won't do great things for catalytic converter lifespan. I would fix that sooner than later.

      Yes, important point. Watch the Motive videos with Herman thickness testing the bores and deck. You do not want to push the unlucky (thin) block as hard as you can push the average block.
