I have always wanted to try out a kicker L7 and I found a 12" Kicker S12L72 for $180 without an enclosure. Since I do not know how stiff the suspension is supposed to be on the sub since I've never owned one. How am I supposed to know if it's blown or even working correctly?

I have one but I don't really know how to use it. The reason why I say that, is the last time I tried it on two brand new DVC 4 ohm icon subs and it kept telling me they were .5 ohm if I remember correctly. Also, I don't like used either, but the sub looks cosmetically 10/10 and he said it was never hooked up, just sat in storage for a year and that's why he is selling it.

Yeah, I looked around online and found them brand new for around $220, so I will barter with the guy and see if I can get him to $130. How would I be able to tell if the sub is good or not though without it being in an enclosure?

I found a used JL W7 AE 12" single 3 ohm sub for sale locally and the seller said that it doesn't have the clamp rings which can be found on Ebay for $50. He also said that it has a small scuff on the rubber which I couldn't see in the low quality pics he provided. I have never owned any JL subs. Here are my questions: 1. Is it very hard to install the clamp rings? 2. Is $275 a good price for it? 3. I have a Cadence ZRS-8 amp which is rated at 50 rms @ 4ohm, 750rms @ 2ohm, 1500 rms @ 1 ohm. Will this sub work with my amp?

I finally received the T/S Parameters.

I Currently have 2 12" Memphis Audio PR's in a dual ported box powered by a Cadence ZRS-8 with stock electrical. The system is in a 2011 Mazda 3 Sedan. I have been wanting to play around with new subs and I got a crazy good deal on a single 12" Kicker CVR CompVR Series sub with a sealed box that fits two 12" subs with their own chamber. When I ask this question, keep in mind that I want to keep my stock electrical. I am trying to find either a single or two subs that will get pretty loud off stock electrical. I want something that will get loud and I'm leaning more towards SPL. Should I build a custom box for the single 12" or should I sell the sub and the box and use that money to get another sub and build an enclosure for it? I don't know the measurements of my trunk at the moment, but the box in there now, is roughly 15" tall, 33" wide, and 23" deep and I would like to stay around those same dimensions, but I would consider going slightly larger. The height is pretty much as big as I can go and the width is maybe 4" from hitting both sides of my trunk.

Awesome, thank you!!

The enclosure dimensions are 32-1/8" wide, 15-1/16" tall, 15" deep. The port is 12-11/16" wide, 12-5/16" long (from front to back) and around 12-1/2" long from side to side. On the inside the port distance from the wall in the center of the box (since each sub has its own chamber) is 3-1/8" From port inside wall to the wall in the center of the box is 12-1/2"

I just got an e-mail back from Memphis Audio and they wanted me to send them pics of my subs. That way they can send me the exact parameters of the subs. I decided I would give you all the information that I could, about my current enclosure, which might help in the new build. I made a sketch of the measurements in PowerPoint, but it says "You aren't permitted to upload this kind of file". If you know of another way that I can upload the Powerpoint drawing, please let me know and I will upload it, or I can just send the measurements to your e-mail. Here is a pic of the enclosure, first is the left side of the box. 2nd pic is the right side of the box.

I just e-mailed them asking for optimal box spec and t/s parameters. I'll let you know when I hear back from them. . Hopefully they have quick customer service.

I will do try and do all three. Thank you so much for saying "dont remove any factory wires just add them" I would have removed them haha. After I do the Big Three. It sounds like everyone is recommending me to keep the 2-12" Memphis Audio PR's. If I keep them, what type of enclosure should I build? I have access to a C&C machine so things should go pretty slick for building an enclosure.

I like my current setup, but I just wanted to try doing more of a SPL setup to see if I like it better. When I say loud, I mean that I want it to move air inside the cabin and shake up my car lol. I don't have the big 3, everything is stock. If this is cheap to do, then I wouldn't mind trying to do it (since I've never done it). cheap = under $20

I will check that when if I end up going to look at them. I guess I should clarify my $275 for it. I told him I would trade my 2-12" Memphis Audio PR's (500 RMS Total) in a dual ported box plus $130 cash. That would be a fair trade, don't you think? Why not just use one of your Icons? Because, in order for it to hit hard it would dim my lights and I didn't want to kill my alternator and the W7 is less RMS, but if it also dims my lights as well then I know I can sell it for the same price if not more. I don't want to spend money on upgrading my alternator and battery since I plan on selling my car this year.

I already have 2-12" SSA Icons but I am waiting to use those in the next vehicle I get since I don't have the trunk space for them right now. I'm not scared to buy a used sub since every sub that I've owned, except my Icons, have been used when I bought them.

Sorry about that, they are 4 ohm. So if I remember right, I can get them to 1 ohm?

I am going to be building a box for my 12" ssa Icon in a month or two and I couldn't stand not having a sub in my car so I bought two 12" DVC Memphis PR's (250 rms each) and the box that they're in was built so the subs could have there own chambers so it has two ports (a port on the left side and a port on the right side) and it has two cup terminals (1 per sub). I have a mono block amp and I have two positives and two negatives running off my amp (1 pos. and 1 neg to each sub). I am not sure how the subs are wired inside the box so I don't know if they're parallel or series. I have a Cadence ZRS-8 which puts out 1500rms @ 1 ohm and 750 @ 2 ohm and 250 @ 4 ohm. So my question is, how should I wire the subs since I have two cup terminals to get the most output from my amp to the subs so it doesn't put as much strain on the amp?

I maybe getting a 12" JL W7 which the guy is asking $350 for the sub. I will listen to it before I buy it, but is there anything in particular that JL W7's have problems with that I should be aware of? Next question, I have a Cadence ZRS-8 amp. Will this amp be ok running the W7, because I think I read that they're a 3 ohm sub? Here are my amp specs. 4 Ohm Competition Rating: 50W x 1 2 Ohm RMS Power: 750 Watts x 1 1 Ohm RMS Power: 1500 Watts x 1

My dad is going to help me build the enclosure with his CNC machine so things should go smoothly when cutting the boards to their correct lengths. Right now I have a 2.3cu. box tuned @ 33hz (which I built it myself) and it gets decently loud, but I want to get louder which is why I decided to make an enclosure which will hold two Icons. I listen to a variety of music such as heavy metal, alternative, rock, R&B, rap, techno, and some dub step. I will get back to you with my trunk dimensions when I get home from work. I want to use this box as a daily use, but I still want it to get loud. What type of box will be the best to build to achieve this? On a side note, I also wanted to do a flared port. I'm not sure if this will affect the type of box to build or not.

I can't figure out how to attach an image that's saved on my computer, but I put those dimensions in the "RE Calculator" (online enclosure calculator) which it says with those dimensions it will be tuned to 25hz and then I drew those dimensions up in "Sketchup Pro 8" (I put a 6" radius for each sub, which I'm not sure if that would be correct or not) and the subs barely fit onto the face of the box and I wouldn't be able to kerf it. Am I doing something wrong, or is one of the dimensions wrong?

You're the best! Thank you Now that I have the dimensions for the box. I have a few other questions. 1. I want my box to look good and unique so I was thinking about doing carpet and stopping maybe 2" from the face of the box and painting the box glossy white or black and doing a red ring (which will outline the mounting position of the sub). What type of paint is going to work the best and not crack/peel? 2. How do I do a Kerfed Slot Port? 3. I want to put "SSA Icon" or just "Icon" on the box somehow. With an enclosure that will hold two subs, how would you put SSA Icon or Icon on the enclosure to make the box look unique?

Yeah, I did look at SSA's pre-designed optimal ported enclosure for two 12" Icons. Do you think that is going to be the best route for me to go? If it is, then I will need help with a couple of the dimensions because there requirements say 36" wide and my trunk is only 33" wide (smallest point in the trunk)

Anyone know which enclosure would be the best for me to build in order to get what I'm trying to achieve?

Glad you mentioned that. I mean Kerfed Slot Port.
