Eclipse CD4000 and a subwoofer

[king alpha 0]

My dad got a used 05 Mustang back in the summer, and it came with a Eclipse CD4000 deck in it. I got him a pair of Alpine Type R Componant Speakers for Christmas. I was planning on installing it for him, but he insisted on haveing the car audio shop I got it from to install it (yeah, he don't trust me tearing apart his car).

Anyway, I also had a Pioneer 2x60 Watts laying around to power the componants, and a Massive 1000 Watt amp and a 12" Adire Brahma. I took the Pioneer and Massive amp along to have the shop install those too and feed the wires for me, so I have the sub amp ready for the Brahma.

So, yesterday, I stuck the Brahma into one of my old boxes (a sealed box that's a little less then 1ft^3), and hooked it up the the Massive amp. No Bass from the sub at all. No movement nothing. The light on the Massive is on, so the amp works and I checked the wires on the amp and the sub and it's all correct (BTW, the Brahma is Dual 2 ohm, and I have to hooked up for 1 ohm: amp + to both sub +'s and amp - to both sub -'s).

The only thing I can think of is maybe the RCA is hooked up wrong in back of the Eclipse (rear pre-out instead of sub pre-out) or there's something set up wrong on the actual Eclipse deck.

Now I can pull out my Alpine easily from my 95 Mustang, but pulling out an Eclipse from a 05 Mustang looks a little more complicated (some panels seem to be in the way, and the face don't come out to access those clips like the Alpine). So, I'm asking about the settings of the Eclipse, and if maybe there's a feature that I'm missing that's making me lose bass. If not, then I gotta tear the car apart.

Sure the main fuse is in? Sometimes the remote can supply enough power to turn the lights on but no power for actual amplification.

The Massive P1000.1 dosn't have an external fuse for me to pull out. And the fuse by the battery is in.

Measure the voltage going in on the supply, the remote, the rca's and the output voltage and your answer will be pretty obvious...if not at that point report what you have and we can easily help.

Cool, I'll try that. But my dad's car is at his place, and the soonest I'll be there is Sunday, so I'll check back then.

But I'm not that great at these things so let me ask if this is what you meant?

Set my Multimeter to AC voltage. Put the black neadle on Ground wire and leave it there. Then to measure the supply voltage, I stick the red needle on the Power wire. To measure the remote, I put the red needle on the remote wire (small blue one). And to measure the RCA's, put the red needle on the RCA's (Both?). Then to measure the output voltage, I stick the red needle on one of the +'s where the speaker wire should be. Is this right? Also, do I disconnect the sub? I just want to make sure I don't blow anything.

I found the problem. Pretty simple actually. When the shop installed the sub amp, they also installed speaker wires. But they didn't strip the wire. So the screw from the amp was latched onto the plastic part of the speaker wire. One of the screws actually looked like it pierced the plastic and reached the actual wire, but the other didn't. So, I stripped the wire and the sub works.

Now onto building a better box for the Brahma.

Lol, hurry back to that shop.

That shop is okay, they give me discounts on products so, if I want goods, I'll go there, but won't have them install it. The rest of the install was good though. Now that I think about it, maybe they did that on purpose so the wires don't accidentally touch each other and fudge up my amp.

Funny thing was when they asked me how much speakers I was going to use. I said one. But I asked them if they could put speaker wires on all four speaker terminals since it's a dual voice coil sub. The sales guy said something about it being better use just one pair of pos and neg speaker wire from the amp and bridge it at the speaker and how it'll make the amp stronger that way. I said okay, but when I installed the sub, I installed speaker wire where they didn't. Yeah, in the end, it's the same thing, but it's easier.

Now one more question. The Eclipse pre outs are 5V. The Massive amp's gain knob is for input voltages of up to 5V. Should I assume that the gain knob should be all the way down? I suck at that "listen to distortion by ear" especially when the car has dual flowmasters and sound like a roided import (It's a V6 Mustang, BTW).

BTW: ///M5, not to be a perv, but who's that girl in your sig?
