    Sundown Audio SIA-3500

    This is a bit late but for what it's worth I've been thrashing one for the past few months on 2x SAv2 12s wired to 1ohm without a single issue. Initally the output seemed to be less than the sfb2k it replaced but that was purely due to the intelligent power management responding to bad voltage...

    GM small case alternator upgrade to large case alt

    Why drop $200+ for 25-300a when $20 can get you an easy 140-160 (or double that if you nix the A/C compressor) and when its not enough there are kits to get an easy 200 out of a ad244 or dr44/g. Local pick it yourself yards sell cheap and its easy to find a late 2000/early2010 decked out...

    Adding 2nd battery, how much 'better' is XS compared to say duralast platinum agm (h8/h9)

    Figured I would give a quick update for those who come across this post in the future when trying to figure out if they need to spend the xs money. I went from voltage dipping from 15v to nearly 11v with a ~150 amp indicated load to it going down to maybe 13.7v. Only changes made was installing...

    Adding 2nd battery, how much 'better' is XS compared to say duralast platinum agm (h8/h9)

    I'm pretty sure Johnson makes all of duralast. This discussion has helped me realize that I was starting to be swayed by marketing hype and am going to pick up my $147 h9 agm right now before I have to get ready for work. Hoping that its not like the dual post I bought last night that was over a...

    Adding 2nd battery, how much 'better' is XS compared to say duralast platinum agm (h8/h9)

    We do have access to Odyssey batteries, anything bigger than a power sport is a vendor direct order but my 30% discount should still apply. Are there certain ones I should keep an eye out for? Normally running a 2nd battery wouldn't be a thought in my mind but these 30% off weekends only happen...

    Buck Box Designs - Refreshed Thread

    I feel that, so many people laughed at my 2000 s10 turbo build due to how much duct tape was holding down power lines going over the roof to the bed where the turbo and other gubbins were at, especially the brodozer bros and the 60k charger/challenger owners. All it took was grabbing a gear and...

    Buck Box Designs - Refreshed Thread

    The outside, after a bit of router work looks quite nice. Still figuring out a good gasket setup for the access port as the "sticky tack" style of weather stripping didn't want to compress well and makes it look a touch janky. Since the cheap 144t blade dulled mid way and chipped up the birch...

    Adding 2nd battery, how much 'better' is XS compared to say duralast platinum agm (h8/h9)

    Until Sunday I have the option of grabbing a Duralast Platnium AGM battery for 30% under list price (approx 140 before tax) and I'm planning on installing in the rear of the van within 2ft of my SIA-3500 and Machete MMA-2200D along with finishing up my 0g big three upgrade. Currently with the...

    Buck Box Designs - Refreshed Thread

    I've ditched the SFB in favor of the SIA-3500 that came with the SA 12 kit (spending $80 to get a $400 amp and $60 1/0g install kit was a no brainer) and it's an improvement over the SFB in many ways. Full bridge is the future once manufacturers stop cuttnig corners and build them properly, and...

    Buck Box Designs - Refreshed Thread

    This was a challenge to build using nothing but a 1950s shopsmith table saw with birch 3/4 ply, totally roasted the 144t blade I bought for the build. Despite the flimsy sawblade doing it's best to prevent a straight cut, I got her done (waiting on payday to get some router bits that can handle...

    12 years since my last box, before I start cutting figured I'd get a sanity check on this design. 2x Ev3 12s in 2x 1.76cf chambers ~32hz

    Yeah the sundown e12 d4 v4 subs (specs are on down4sound.com but strangely not on sundowns own website...). I sent you an email with the details. Figured pandora might be part of the problem, are there any streaming services that have fairly high quality encoding/bit rates? I've only ever...

    12 years since my last box, before I start cutting figured I'd get a sanity check on this design. 2x Ev3 12s in 2x 1.76cf chambers ~32hz

    Literally stole the refrence box for the e12 v3 from the sundown site (not realzing that I had infact purchased version 4 woofers with different T/S specs), mirrored it and removed the panel that would have divided it into two boxes. That was done in sketchup since the refrence box came with a...

    12 years since my last box, before I start cutting figured I'd get a sanity check on this design. 2x Ev3 12s in 2x 1.76cf chambers ~32hz

    No pics yet, (van is a mess) but after flipping the subs to sit outside of the box to regain a little bit of CF, rewiring to 4ohm (turns out ~2.6k is a touch much to 2x e12 d4 v4 rated at 300rms) and running the alt at ~15v things do sound a bit better but I'm not very happy overall with the...

    12 years since my last box, before I start cutting figured I'd get a sanity check on this design. 2x Ev3 12s in 2x 1.76cf chambers ~32hz

    After running these for just over a week, I've gotta admit that they don't hit near as low as the 12s I grew up with. Maybe I was spoiled with a single eclipse tc9 12in with 25mm xmax, then dual okur k9 12s with the same 25mm xmax, where at full tilt a cloud of smoke would shift side to side...

    12 years since my last box, before I start cutting figured I'd get a sanity check on this design. 2x Ev3 12s in 2x 1.76cf chambers ~32hz

    I'll snap some pics of the finished build here in a little bit, considering I haven't worked with building anything out of wood in nearly a decade it turned out better than expected. Especially factoring in using a circular saw with no clamp on guide (so. much. sanding.) Despite messing up some...
