Well I don't know if I'm growing up, or just really wanting some better sound, but I'm really wanting a nice sq front stage. Unfortunately I can only adjust the placement of the speakers in the door panels for now, but maybe down the road I'll be able to do some more custom fabrication. This is an 01 tahoe if it makes a difference btw. I am running a set of realm audio 6.5 components off an eclipse ea4000 as my front stage at the moment. I would like to try a 3-way active setup, still using the realm 6.5s and tweeters, and getting either a 7 or 8 inch mid. I plan on running the 6.5s and 7s/8s off an eclipse XA4001 (or another ea4000) 4 channel, and 2 channels of the last amp for the tweeters. Sound deadening will be well taken care of. I have an alpine 9831 in my vehicle now, and I can swap this out for an alpine 9853 I already have but have never used. Would this be a good swtich for what I'm wanting? I hate to ask, but I've never used the other h/u and don't have the manual or time to install the other h/u just to find out it's a step in the wrong direction. I'm selling some of my current sub-stage right now, and once that's gone I'll have a bit of money to throw back in to getting the 7 or 8" mid I need. If anyone could suggest something that would do well and wouldn't break the bank I would really appreciate it. Thanks guys, if there's any more information I left out please just let me know!

I can understand the Q but the recommending the BL (or several mentioned) over the SSD with the power on hand? x2 on the SSD with copper coils and BP option. If you can fit it I'd go with an 18 over the 15 since you want it louder.

Thanks! I sure will be sad to part with them, I've loved them for close to 2 years now, as long as these sound as good I'll be happy.

Well after shipping ill probably be looking at 700 for both subs sold. That means another 500 out of my pocket. 300 would leave me with more green and I absolutely loved my btls. I just want a bit more cone area. I couldn't remove the box for all 4 subs myself, but I could pop 2 smaller boxes out on my own. I'm having a hard time comparing the 18 btl to the 21 dp because they are so different. I couldn't give them the 4000 watts daily like I could my btls, but for comps I think they'd be fine and less of a strain on my charging system to achieve the same output for daily listening. Please correct me if I'm wrong in my thinking?

I wasn't sure if the cost would make it worth it. Online I wouldn't make much off of the BTL, so if I could save some money by reconing I'd rather do that.

Honestly the sundown 3k or a kicker 2500 would be a great choice. The Hifonics amp will do fine, but obviously more power generally= more output.

I always hated when people made these threads but I honestly don't know where to start asking besides here. I am either going to buy 2 21" DPs or I will recone my BTL 18s into 21" dps, I just wanted to know if this could be done and how much it would be? I'm trying to figure out if it would be beneficial for me to just sell them and use the money to buy new 21s, or if I could save a bit and re-use the perfectly good motors (actually the entire sub is in perfect working condition). Please let me know if it can be done, and the pros/cons if possible. Thanks in advance for any help I can get!

I was wondering something similar. I've been running a memphis 4k per BTL and was considering trying 2 of the 21s on for size. I know what they're rated but realistically will they handle 3k or so each? I've had 4 alts for a while and plan on down-grading to a dual alt setup so I'm weighing my options. Thanks!

If it doesn't have the 3rd slug it isn't 'loaded'. IIRC one of the largest benefits was it coupled well with the high xmax coil giving things more room to travel. Chances are it doesn't have the high xmax coils either. Hopefully someone who understands things a bit better could chime in.

Or you can get a router jig at lowes for ~$30. Cuts huge holes, down to about 10 inches, and be very exact.

Such totally different setups, but they all would need at least some electrical upgrades. I would use the kicker 2500 in any one of those setups, just 2 of them with the BTLs- and if you can fit 15" L7s I'd go btl 15s. Having used a 12 and 15" L7 I know they weren't too bad, but I'd take the BTL in a heart beat. The most I've heard on a W7 was a jl 1000.1 I think, and I've just never been impressed. Plus a BTL is almost 1/2 the price of a W7 iirc. You're really going to want a beefy charging system to support 5000+rms though, maybe a MLA module, h/o alt or dual alt setup, and several batteries. If you don't want to do all that maybe one of the other setups will make more sense for you.

It will depend on the install/setup, but it can.

There is no BTL 10 though

2 sundowns. I've used the 2006ds and they were good for the price, but the sundowns would be better imo. Maybe if you can get a 2606d for cheaper. Make sure you allow money/space for electrical upgrades you'll need.

Unfortunately I know a few people that use it Sub looks great.

Def. the BL for that amount of power.

A good amp that will provide each sub with 1000rms will be sufficient. If you aren't too sure, then I wouldn't risk the extra power. The sundown 1k, rf 1k, or many many other 1000w amps will do fine. I'm cheap and would rather have one big amp than a bunch of small ones, so maybe a single sundown 1500 or RF 2k (or again any decent brand 2000w mono amp) would be what you're looking for.

I've used them on several different subs, alpine type-x in the wifes car, btl 18, bl 12. Nice amp for the money imo.

Thanks. I haven't had any problems- but I am working on getting them out of the car all together.

Thanks guys! I'm really not trying to compare/compete with anyone else though, you know? There just are so few 'big' setups around where I live in SC-and no one with more than dual alts.

The btl is really inteded for ported use. I'd go with the 30-32hz tuning and see how you like it,

I've been running things off 1 alternator and 5 optimas for quite a while now, problem after problem kept delaying me getting my charging system right. About a month ago I finally got everything in, and just figured I'd say I'm very pleased. I ordered 3 alternators and a 4 alt bracket through Iraggi and was met with terrible customer service. He didn't respond to emails or calls for weeks on end. I finally got the alts in twice the time he promised (the only reason I went with him for alts) just to find he didn't send my bracket. After being promised I'd be called for weeks and even having his girlfriend/wife answer to just hang up on me the bracket finally arrived. I don't mind a long build time- understand that. It's just a problem when someone says one thing and does another. Also all my alternators look different inside and out. 2 of the cases are obviously refurbs, and the internal parts of 2 of them look used/blackened. I will say everything seems to be working good now, and the bracket was really something I couldn't get anywhere else. On the other end of the spectrum I ordered an MLA module to go with the alternators. Good thing I did- because even after 2 shipments and 2 orders Iraggi didn't include the wiring (plugs) like he said he would. The guys are absolutely awesome. Respond every time, answer the phone during business hours (and often much later too) and shipping time was just a few days after build. They even kept me updated during the build. I recieved the first "Pro" module, which has a few features the original didn't including a high/low setting so that I can go from around 15.5v around 1000rpms to 14.4 for daily use. My factory idling voltage was 13.8 btw. MLA has been absolutely fantastic, and I would recommend them as a company, and their product to anyone. I have 3 spools of kicker 1/0 wire to add in the mix, but with 8,000rms for 30+ seconds of test tones the voltage at the front doesn't dip below 14.3-14.4. There is voltage loss to the back, but I have to add all this wire in before I really go into that too much. After I add in the wire I'll post up how it holds 16,000rms. The final product: MLA module, 1 130a alternator and 3 "380" amp alternators, with 6 batteries. On to pics: Bad directions ftl- have to move a few things to add in those extra pulleys. So far it'll do 152 and change sealed at the dash at 32hz, but I that was the first time I've metered it since I've done a bunch of changes, so plenty more to go (including 2x the power). door open

Even with 2 layers of wood (mdf, birch, etc) you will want some internal bracing. Good luck with it, and focus on your charging system before everything else- I learned that the hard way

I like the sound of my bros BL 12. I think it 'gets the lows' better than the alpine type-x I have in my wifes car, which is meant to be an sq sub. I think you'll be happy with it in the right enclosure.

^ x2. A larger box will increase the efficiency, but decrease the power handling. Vice versa.
