[QUOTE="Eviljacket, post: 8765326, member: 684057"] Hey all, long time member (Tekjive) but can’t remember my password so had to create this acct just to post lol I’m looking for help/advise on choosing a coil to replace my SWX-1243D coils. I need to do 3 (2x12” & 1x10”) so this first needs to be a success, my goal is to keep or exceed the SQ & power handling. This will be my 1st recoil but I’ve been reading and discussing with friends for weeks and confident I can easily do this, I’ve already disassembled my woofers fully and carefully, saving all stock parts so I can keep what makes the Type-X a Type-X, posted pics on below Reddit link: [MEDIA=reddit]CarAV/comments/ppyh8e[/MEDIA] There’s a second post with more pics if any interested. But ya, learning the hard way there is basically ZERO info online about these subs and recoiling them, because of the difficulty in disassembly I imagine and the fact no one makes an inset voice coil (inner and outer wound voice coil, which is superior in sound quality) so I’m “reduced” to using a traditional wound coil, and I’m having a hard time choosing which/what/etc. I know the stock coil is dual 4(3.6)ohm 3layer round CCA inner/outer for a total of 6 layers. I wanted to go 8 layer full copper flat wire but can not find one. I just bought a 4layer dual 4ohm flat copper wire coil below, which is 57mm vs 50mm but I’m replacing the spiders as well and was just going to compensate when installing figuring the extra xmax might be nice (lol) the dual 4 flat copper is whatme me jump on it [URL]http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&toolid=10001&campid=5335951755&icep_item=143093457584[/URL] But after receiving it it doesn’t look near beefy enough, Jorge at LoB said it’s 1kw RMS, which is the minimum I want but man it’s looking paltry :/ really wish he had this in 8layer, there’s a dual 2ohm and dual .5ohm I’m looking to maybe exchange mine for and they have the same wind width as stock, but both are 8layer flat alum 1.5kw RMS, which I prefer for RMS, but I have questions I can’t seem to find answers for.

Just for info purposes the specs on stock coil are as follows (12” & 10” are same exact Alpine SWX-1243D Stock Voice Coil Former height: 115-ish mm Wind Width: 50 mm Outer: 84 mm Inner: 76 mm Impedance: dual 4 (3.6) ohm Layers: 6 Former Material: alum Wire Type: round copper clad alum Wire Gauge: ??? Stock Motor 130oz 5/8”x3 Triple stack Gap Width: 6mm Gap Depth: 73mm Outer: 87 mm Inner: 75 mm Top Plate: 12mm All measurements made by me and triple checked. Couldn’t find any spec info like this at all :/ [/QUOTE]
