Help!!! Just installed my RL-P, something is very wrong!!!

[Hundreth 10+ year member]

with my headunit, i cannot set it lower than 80. Its either full, 80, 120, or 160. And with the wiring, how hard will that be to switch the wiring? Will i have to rip the car apart again? Or are you just saying just unplug both power wires and switch them with eachother?

I am telling you to set the lpf on the amp lower, not the headunit...

It should be very easy for you to switch the power lines between the two amps, just unplug, switch them around, plug back in //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Also, how is the signal reaching your Nine.1, are your amps daisy chained? does your Nine.1 have its own set of RCAs or is it chained to the Nine.2?

If its going through the Nine.2 first, you might want to check the Line out settings to see if you are getting the correct signal, I have a feeling that could be an issue with you since you say that there was a difference after they installed that amp.

If they aren't daisy chained, try disconnecting the nine.2 and run the nine.1 alone and see if there is any difference.

Let us know so we can fix this crap //content.invisioncic.com/y282845/emoticons/2thumbs.gif.fdc3ba010dbb42b61704534b46d02fe4.gif

I appreciate your help. //content.invisioncic.com/y282845/emoticons/blush.gif.99bc659ee2012b7d826165e26fb5eebe.gif No the amps aren't daisy chained, they both have their own RCA's. I have a Distrubution block and both amps are running through that. No line out RCA's on either amp, each one is running independent. Tommorow morning i will switch the power wires, but i have a feeling that won't do much. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif BTW the Nine.1 has an amp current draw of 130, dunno if thats alot or anything. The Nine.2 is like 40.

Ill also disconnect the Nine.2 and see whats going on. If i switch around the wires, do i have to discconnect the car battery positive terminal again, its a huge pain in the ***?

Switch the power wires even if it doesn't help, its silly to have bigger wire going to the amp that requires less current. However, with a distribution block you should still be getting a good amount of power through that 8 guage. Try it anyways and see what happens.

Don't forget about the lpf either, it helps. Other than that I really don't know what to tell you without being able to see whats going on with my own eyes. I would advise you not to switch to ported until a week goes by atleast to make sure that break-in argument is put to rest. An RL-P in a sealed box in a car the size of yours with that much power should rock your socks, no question about it.

I have a sub with similar excursion capabilities to yours and in its sealed box i murder other ported setups in output and sq a lot of times. My friend does the same with his sealed W7. So don't lose faith in sealed boxes so fast... your sub has the displacement potential to make them work.

on another forum they are telling me that something is wrong if the Nine.1 isn't blowing the 8 guage wiring kit fuse (i assume its a 60 amp fuse), since it has a current draw of like 130 amps. What do you think about that? It hasn't blown any fuses yet at all, and i have been running it pretty hard, and i assume its hooked up to the 60 amp fuse or whatever came with that 8 guage wiring kit.

What they are saying could be true... but its probably not because the amount of current a certain size wire can handle is directly related to how long it is. So since you have a distributor block, its very possible that the 8 guage is still enough to handle the current demand of the Nine.1 given that the 8 guage wire is short enough.

ok. On another note, how can i make sure that my sub is wired in at 1ohm and not 4 ohms? My amplifier has 2 sets of speaker terminals on it even though its a 1 channel amp. Both terminals are apparantly internally bridged.

Well, as long as your sub is wired in parallel correctly, i highly doubt it would matter what terminals you use on the amp.

If you wanna be sure, you can simply hook it up to each of the possible 3 configs: The first set of terminals, the second set of terminals, the pos from the first and the neg from the second. I'm 95% sure you won't be able to tell the difference from any of them.

SOmeone was telling me I have to hook up all 4 terminals with wires and then run each one to the respective sub terminal, otherwise its not running at 1 ohm. Is that correct?

well ok, i guess the ohms are correct then. IM gonna switch up the power cables like you suggested in the AM, as well as lower the sub crossover. Thanks for your suggestions, ill post up what happens after i do those things.

OK, I responded to your post on the other forum, but forgot to mention something else. There is a switch on the amp that says master/slave. Make sure it is set to master!

There can also be a problem with having 2 passive xovers set close to the same freq. I'd suggest turning one of them off. Since you cannot turn off the xover on the Nine.1 (I have one, I know), I'd suggest you turn off the xover on the HU, then adjust xover on Nine.1 down to 60-70ish. What I did in my car is I just turned the amp xover all the way up to 240, then let my HU xover do all the work, I've got my 13kv2 crossed at 60 with a 24db slope off my x889 hu. sounds freaking tight.

The people who are suggesting a larger sealed box are giving you bad info. The recommended sealed box for that woofer on 600+ watts rms is "less than 1 cu ft" according to the soundsplinter website. You might consider tossing a block of wood inside the box to make it smaller, this would be more help for the sq than a larger box lol.

And for the other folks saying 8 ga is fine for a nine.1... OMFG! you are so wrong! The only way 8 ga would work in this setup is if there was 1/0, or 2 ga running from battery to back of car, then split off to the amps with VERY SHORT RUNS of 8 ga. If you do have a setup like this, and the 4 ga is going to Nine.2, simply switching the power wires between the amps will work fine. Just make sure to swap the ground wires too if they're different sizes.

It'll give you a much steeper slope. I guess whether or not that is a "problem" depends on how well the steeper slope works for you.

Um, no. Smaller boxes are worse for sound quality. Making the enclosure smaller would increase the mechanical power handling; but at the expense of sound quality, low frequency extension, etc etc.

I didnt read the 8 pages. Was this problem fixed? Was it wired out of phase?
