OK, I finally had the new 12" RL-p installed into the Audi A6 wagon last week...and I was very disappointed (and mad) when I listened to it. I took it to a decent shop and had a 4 gauge amp kit run to the back of the wagon. I built the box myself, and it turned out very nice. I posted pictures a week or two ago. It is a sealed 1.4 cu ft box. The amp is a cadence 600x1 at 2 ohm (model A5+HC). I bought a Navone Engineering NE-7V LOC, which is supposed to be the best available. When I entered the car for the first time, I was shocked at how bad and quiet the sub sounded. From reading posts here, my hopes were through the roof. However, I was really let down. I am positive I could buy a $80 sub from best buy and get the same sq and spl. When I reviewed the install, the only issue I could identify was both sets of wires on the LOC were spliced only into the right channel of my Audi (at the rear factory amp/sub). The LOC is on the front page of http://www.autosound2000.com/ . If I turn my balance to the left, the bass is completely killed. I don't know if this could be my problem, but I am really disappointed right now. What else could it be? The sub sounds terrible when I turn it up, and it doesn't get near as loud as my two old IDQ 12" that were in the TRUNK of my Lexus (same amp). I thought that the open hatchback would increase the sound pressure, but it pales in comparison to the other setup. I don't know what to do at this point, so I would appreciate any help. Is there any way to tell if the amp is the problem? I am in central Ohio if someone can lend me a spare amp to try. Thanks, MX

1) Where do I get a cheap DMM? 2) gains are set at max, otherwise there was very little bass. 3) Is in phase the same as in parallel? The amp has a phase button on it, but I don't know what that is. 4) how do I measure incoming voltage? Thanks for your help MX

According to David Navone, this LOC is competition grade. This piece was highly recommended by Caraudioforum. I will take some pics of the install later tonight. Hopefully you see something I don't! Does anyone live in central Ohio? I could use a second set of ears to test this setup, because it just doesn't sound good at all. MX

Hi guys. I am going to build the box for an RL-p 12" today. I made some measurements in the wagon, and made this design. Take a look at the attached diagram. I first made external measurements, and then I adjusted for the 3/4" MDF. That adjustment took away a LOT of cubic feet, so I need you to verify that the calculations look correct. Sorry, but this forum won't allow me to upload the spreadsheet. Thanks, MX Sub_Enclosure.doc

mrray, Actually, the finished product is 1.42. Somehow I missed the calcs, since I was originally planning for 1.25. The 3/4" internal measurments through me off once or twice The box is very solid, and the fit into the Audi was flawless. I designed the back ridge to slide under the cargo bar in the back. Fit was to the 1/16th inch. Now I just need to find someone to carpet the box. Matching navy blue carpet would look like it was straight from the Audi factory MX

I will...as soon as I order the sub MX

OK, box is done. The finished product came out with a little more cubic feet than planned. Plan was around 1.25 - 1.3. Final space is around 1.42. Do you think this will be OK? Enjoy the pics. MX

OK, I will give it a try. I just got back from Lowe's with the supplies. I will post pics of my progress later tonight. MX

Hello everyone. New to the forum tonight. I spent most of today searching the net for a new 12" sub, since I have been out of the car stereo world for about 5 years. Wow, times have changed. Amps are huge and speakers are taking more watts than I can remember. I have an Audi A6 Avant (wagon), and I want to find the best 12" sub that I can run with my Cadence A5+HC 600x1 2 ohm amp. I listen to more rock than anything, but I also like trance and rap and country and etc... So, is it safe to assume the RL-p is one of the best choices available? How soon will the new sub be out? Any idea how much it will be? What is the best price for the RL-p? Finally, let me know if you think 600 watts is enough for this sub. If so, what is the optimal size sealed enclosure. Thanks, MX
