Some background: I have always been a Sundown audio and FI audio fan and those are the products I use. I purchased a 12" BL fully loaded and 1500D sundown to place in my 240sx, I have now upgraded to a 04 Acura TL. I cannot afford a new headunit as the products available are close to one thousand dollars. So, the box is built, the sub is ready, the wiring kit is sitting waiting to be installed. Now where im stuck, So, since i have the stock headunit I will need a line output converter. I am unsure how to install this and how it works. Also I am needing to disable the stock subwoofer. I have been reading about how the stock headunit lowers bass at higher volumes to protect the speakers etc, will this affect my subwoofer? Installing items is no problem I just want to make sure im doing everything right and that i am getting the best performance from the system. All advice is appreciated, if anyone has done an install in the same car or a similar please due tell. Cheers!

Thanks guys just gotta grab my buddies dmm from him and i should be good to go. Hopefully my gain changes the voltage, as it did not alter the output of the subwoofer. *EDIT* could it have to do with settings in my headunit?

Yeah that was basically my point. It will be in the box by the end of this weekend because I am busy with school. Any ideas about the gain? Use a dmm to set it. What is the volatage im looking for though, from my OP I last used a 60hz CD and set the gain to around 30 something volts. Where can i calculate this voltage.

It sounds more like a rattle, ill have to take a video tomorrow as it is to dark tonight.

I understand, but my main concern is the gain. As far as mechanical noise, is it very noticeable Duran? I believe it is just that because it sounds like movement noise in the coils.

Thats what I am hoping the sound just sounded very strange to me, the reason i was playing it out of the box because i am thinking the is a problem with the gain. I remember in my old set-up when i turned the gain know to min the sub wouldn't move. Now at 60% volume the gain does nothing to alter the sounds of the woofer. Still don't understand why you would play it out of the box? Because I am just doing tests with the gain, the sound might just be mechanical, I am not sure. My worry is in the gain. Changing the gain at any volume does not affect the woofer at all, I find that strange compared to my last 18" BL. I am a student and cannot afford to purchase a new sub, because with shipping and brokerage fees this sub cost me over $550. I am trying to make sure I don't place it in the box and the sounds disappears only hiding a potential problem, and ending up with a blown subwoofer.

Update: Playing the sub out of the box sounds like complete shit. It sounds like its rattling underneath the cone somewhere in the magnets. When i mess around with the gain it does nothing. The sound is there at low levels of volume and gets louder when the volume is turned up. With the volume at 50% it is very noticeable, and changing the gain does change the output or the noise, not 1%. Ive tried disconnecting the gain knob extension and nothing happens. Please help, I just want to get this thing working properly.

Ok so My FI BL 12" just arrived, i had a 18" previous in my Ford explorer. Now since I have a 240sx i need something smaller. I have my amp (saz-1500D) all set-up and ready to go. I forgot i need to reset my gains because when I tested the sub I could hear it clipping, and for some reason my gain (min/max) control knob mounted at the front of my car did not change the output of the sub. I lost the original cord but i read a phone cord could work so i tried and the blue led works at least. I digress to my problem which is that i forgot how to set my gain. I remember sticking in a 60hz cd at 3/4 full volume and reading the voltage from the amp but i forget the calculation. I also have a stock alt ( i believe 85amps), and a new battery. I really do not want to harm any of my precious equipment so all advice would be greatly appreciated. Thanks, in advance. Greg

Im going to go off of the cut sheets for my box and pray that it fits. No matter what its going to be tight.

The trunk opening for my car is very large so fitting a box wont be a problem. Also with the cut sheets im not sure if i can fit the 17" length, ill have to do a second measure.

So after being bassless for months now my FI BL 12 is on its way. I drive a 240sx now so i do not have much trunk room, I need help with a box design that would be optimal for the sub. Thanks for the help in advance. Trunk Dimensions: Height Sloping from 20" - 17" at the back. Length: 15". Width: 36". Simplicity is key since i do not have access to many tools.

Ever think of getting new exhaust?

That seems like a good idea, th borders about an hour away from me, but how would i do that. Also I cant seem to find the 10" on their site.
