You have turned off your "POWER IC" option. This truns off the internal amplifier and only attenuates the output the the RCA terminals. That's why only your sub output works.

I have this subwoofer eclipse 800 watts peak, 8 ohms , and i would like to know if the alpine pdx m6 can deliver 600 watts rms at 8 ohms too, o just at 4 o 2 ohms, i will appreciate your help.


No. It is optimized to deliver 600 watts onto either 4 or 2 ohm loads but will decrease to 300 watts into 8 ohms. However that equates to only about a 3dB difference in output level from the sub. 3dB is the smallest amount of volume difference the human ear can pick up. A doubling of volume requires a9dB increase which requires a tripling of input power.

What is the best amp for one 15" alpine type r?


sub spec 250watts per coil you should be just fine I have 2 typr 15s on orion hcca 2500 1 and it kicks a$$ thats 1000 watts over the rated limits of the subs only shut the amp down once these subs can take a lot more power than they say just use your common sence with the volume and gain levels

I can no longer adjust my subwoofer level from my head unit. I used to be able to in my other car but since I put it in my new car I can no longer adjust it? I have the alpine cda-9886.


make sure that before the sub woofer is hooked into the stereo that the settings for the sub are blank that way there is no previous setting once you have hooked up the sub and amp.

Subwoofers pop then immediately produce no sound


Sounds like the two subs wired together might be too much of a load on the amp and it is shutting off. Try wiring the two subs in series. That will reduce the load on the amp but will conversely put out less power. Less is better than none though. In any case check your amp to see what the lowest ohm rating it can see, that ohm rating is where you want your subs and if faced with a choice of either going under (lower numerically) or over (higher numerically) GO OVER!-it is much safer.
Here's an article I wrote that can help explain how to wire the subs to the amp.

OHM LOADS, SUB WIRING, OHM RELATED POWER OUTPUT

SERIES SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the negative pole of the other voice coil (on the same sub). This will leave you with a positive pole from one voice coil and a negative pole from the other giving you the two leads that will be hooked up to the amplifier or other subs. When wiring in series, the ohms will go up numerically, and the load on the amp will go down. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

PARALLEL SUBWOOFER WIRING
Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the positive pole of the other voice coil (on the same sub). Then wire the negative to the negative in the same way. You can then wire to the amp or other subs. When wiring in parallel the ohms will go down numerically, and the load on the amp will go up. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

MULTIPLE SUBS USING SERIES AND PARALLEL WIRING
In order to match your amplifiers ohm rating you can use parallel and series wiring together, just keep things even for power distribution and to avoid phase issues.
Example: I have two “Type X 12” subs” that have dual 2ohm voice coils and have to match my “Amplifier X” ohm rating of 2ohms mono. In this case, I would wire each subwoofer in series (giving me a 4ohm load), and then wire the two subs in parallel to get my 2ohm mono load. When wiring multiple subs just, treat each sub as a voice coil and wire accordingly.

POWER OUTPUT AND OHM LOADS
For example if “Amplifier X” can make 100watts@8ohms, it would make 200watts@4ohms and 400watts@2ohms. However with every drop in ohms the amplifier is put under more pressure. It starts to create a lot of heat, distortion figures begin to climb, damping rates drop, and some amps even throw power spikes when clipping. SO BE SURE TO CHECK YOUR AMPS RATING AND DO NOT EXCEED IT!

When volume turned up subs pop then immediatly produce no sound


u might have to turned your amp so u can play both subs your amp might be to small to run both subs at the same time an u gotta play around with the settings on your cd player so when u blasted your subs it has that nice bass to it not that poping sound.

Has my subwoofer been blown?


hook ithe sub up to a 9volt battery and see if the woofer moves... You will not dammage the suub testing it this way.

I have an alpine 9886 and I dont have volume out of the 4 speakers but my subs are working.


if you have the deck keys try pulling the deck out and check the rca's or speaker leads to ensure all is connected properly. if not then solve. if so then it leads into more trouble shooting. best thing about car audio is it is typically a process of elimination. start with power and ground and then check signal wires and connections.
