STEPPING IT UP A NOTCH And I Need Your help - I Recently installed dual 0ga runs for my bc3500d crescendo and have a few questions about my next setup. 1st. what size fuses should i use for under the hood since theres 2 runs? 2nd should i fuse after my second battery ? if so what size on those ? i will be getting a new secondary battery (old one gave out) what would be a recommended battery for this amp? 3rd I'm planning on upgrading my alt, i was looking at the 320 amp mechman what you guys think? And Last (i Sold my 2 12s Crossfire c7s, thinking of getting 2 15s ) what subs would you guys recommend for this setup ? Btw All of this is going in a tahoe. Thanks in advance

I recently bought a crescendo 3500 for my American bass hd 12s dual 1ohm I know they’re underpowered and noticed my clipping light comes on yet I can hear the subs distorting I haven’t tuned the amp quite frankly never tuned any in the past yet never blown a sub or amp just wanted to know if a little clipping is bad?

I recently bought a crescendo 3500 for my hd12s and noticed that the clipping light turns on at a certain volume I haven’t tuned my amps but I don’t notice or here and distortion I have it on my daily driver, i never really tuned any of my past systems yet never had a problem with distortion/clipping does it matter if I get a little clipping in my system?

I had the 2 15s in my envoy but due to very limited funds I'm moving the box (and rest of the build) to my mom's car for my trip to Florida in a few months. The box is pretty small for 2 15s so why will fit in her car with no issues. Question is How should I go about making my box fit in my moms trunk?

I’m buying 4 2ohm subs yet I’m putting them in two separate boxes I’m going to wire it down to 1 ohm but the problem is how would I do it since there’s two separate boxes?

Does anyone have ts specs on the crescendo contralto 15s?

So my builder, Aho Audio out of Oklahoma, put this together in 12hrs for me today. Huge thanks to him for sticking it out after made the long drive to him. Singer 275a D6500 under the hood 2 d3400 in the back Modified all stock spots to fit 4 Cresendo neo 6.5s and 2 ft1 tweeters. Ran out of time for the Alphard Audio tweeters so future add on down the road. 2 Crescendo 15s Sundown ns1 v1 amp 2 Sundown 50.4 for mids Box is tuned around 40hz maybe less, not sure since space was limited and had to get creative to put the box in.

I'm trying to design a 4th order for my Dodge charger, but I'm not familiar with bassbox pro. Just wondering how everything looks. I found a design on here that was almost exactly what I needed, but not enough space on vented side so I did a little tweaking. Going for 45-50hz with 2 cubes on sealed and 4 for ported side, for a 2:1 ratio. Not everything is filled in, like fb or f3, but just wondering if it seems solid. I couldn't put the contraltos in as drivers so that it will tell me everything, cause I couldn't get the driver list to update, it kept having an error.

Hi guys, its been a while since Ive posted anything at all on this forum. I've been around lurking a few time hear and there and never lost interest in the hobby, but life happens and you don't always have time or money for the things you love. Well that's why I am back, technically we're back, this is going to be the build log of my hetero life mates 2016 ford focus st3. We've bullsh!ted about doing a build here and there, but now things are finally underway. Let us start by saying the "stock" radio isn't exactly horrible, its done him well so far but we both knew from the beginning it was never going to be enough. So after a few sessions talking about what we could do, what he wants out of it, and what would be best for his music tastes, we decided on somewhat of a SQL system. Then more talking and researching this is where we are currently at... The power-plant.. 4/0 Big 3 Upgrade(because why not) Kinetik HC2000-PRO under the hood US Alternator high output alt 2. In the middle Crescendo S800.4 2x Crescendo Mezzo SQ2 comp sets Rockford fosgate 3sixty.3 12 awg knukoncepetz speaker wire 50ft each of knukonceptz OFC 1/0 awg Red/Black 60+ sqft damplifier pro 50+ sgft luxury liner pro 3. In the back Crescendo 5.5K FI Audio BTL Neo 15" 8 awg "speaker" wire Now I know ill probably catch people asking why the 5.5k when we could easily get by with something smaller, but that's what we settled on, and running at 2 ohms should work out great. Besides that we know we have a lot work ahead of us, but we've already started. I've played with a few ideas on different enclosures, and have a general idea of how we are going to fit the system in under the factory rear gate cover. Stock there is about 40in wide and about 15" high and about 23" deep of room. But if we build our own false floor to replace the factory one and remove the FULL size spare, we can easily free up another 5-7in of height. So that's what we are doing. Then plan currently is to build up and modest false floor and then house the 3sixty the factory amp and the 800.4 under neath it, with an extended USB port for the 3sixty inconspicuously located somewhere easily accessible once everything is installed, and possibly a fan or 2 to help keep everything cool under there. Well run 2 sets of power to the back under the car, possibly a ground or 2 as well seeing how thin all the sheet metal is back there. A distrobution block will be required in the back as well to feed power to the amps. the 3sixty will probably steal power from the factory radio, but maybe not. The doors will get the full treatment, hopefully we can form some sheet metal in all the dead air between the door frames(there will be pics a plenty). My having access to a full welding shop comes in handy there. We already got a decent amount of damplifier in the roof, but there really wasnt any room for the luxury liner and i dont think it would be crucial if it was left out so we did. Plus just getting the headliner out and back in again was enough of a headache. Currently the carpet and the seats are out and we're ready to start putting the damplifier on the floor and pillars and rear quarter panels. I'm sure Ill have more to add as the week goes on, but most of the progress that I'm helping with will be on the weekends, as we work opposite hours. (Note: Not everything as been purchased yet, some not for the lack of trying *cough*crescendo amps*cough*) TL;DR: Cool build incoming, Stay Tuned!

OK, I guess it is time to post this build up. It's been in work for a good bit now but I have not wanted people to have to deal with wading through 70+ pages of a build just to see a bunch of gossip and crap. Truck is an 06 H2 that has not had an easy life it looks like. It was bought and sent to me sight unseen and showed up in much worse shape than pics showed. I'm pretty sure it has been on fire a couple times - once under the hood, one time about halfway back by the rear passenger door, and once in the far back. Lots of burnt material for sure. The body is pretty straight with minimal dents - all the chrome is fflaking off badly, front doors are both cracked, driver door handle missing, liftgate was cracked out, wheels are 22" KMC super corroded chrome specials, with 2 new and 2 bad tires, and I got free freshwater ponds on both the driver and passenger floors that magically refill every time it rains. No system installed, no sound - - pile of gear laying in the back... Starting to sound like a Sir Mix-A-Lot song..... It came with some gear that was in good shape - 4 Crescendo BC5500, 2 1600.2, nice A pillars from epicenter? It came with some gear that was in OK shape - 10x Crescendo 10's (8 good) with some decent extreme door panels w/ room for 5x each. DC quad alt bracket w/ no mounting hardware. It came with some gear that was in bad shape - 6x crescendo supertweers - all broken but one, tons of 0 gauge wire w/ free burn holes throughout, Sundown 100.4 - hope it works. 3x singer 400A alts. Also came with 21 16v kenetik batts that came pretty alive with a nice charge. So, the plan came out to be 8 level 6 18" DC subs 8 Crescendo BC5500 21x 16v batteries 3x 12v batteries 3 400A ext regulated alts DC power 180 amp 12v alt 2 1600.2 3 4 ch amps built in XS power 16v charger audiocontrol overdrive Alpine W205 w/ rearview cam Box o' dual inputs Kicker 1/2d EQ Motorized amp rack Directed alam/remote start Lots of 0, 8, and 16 ga wire - company to remain unnamed for now bulk packs of deadener selenium 350 supertweets x6 DD 1" silk tweets x4 More stuff that I probably forgot - DISCLAIMER: I'm not talking crap about the previous owner or anybody who had a part in the build(s) on this truck before I got it. I'm just going to lay this build out from the start. DOUBLE DISCLAIMER - I'm pretty sarcastic so if I say anything like I'm cutting factory wiring out to make the truck lighter and faster....I'm probably full of crap. It's a few weeks from completion.

I used the FT1XOVER passive crossovers, 5 khz High pass 12db/oct slope, for each tweeter and switched my RF T400-4 to AP since it would not be in use. I also DD-1 the amp and Audio Control Matrix line driver properly. (I do have a CC-1 as well BTW) Since then they have been cutting off way before clipping and I've adjusted the levels down some and still no luck. Now a new problem has arisen where my iPod will click on and off when playing at high volume. I wasn't sure if this is linked. Any suggestions? I was thinking about just using a separate amp for the tweeters, but don't want the expense. Thanks!

I'm starting a new build now, some of the old parts will be reused but I'm going for a cleaner, better sounding, smaller setup this time. The old setup was just killer on the suspension of the car and it had to go.

Update 12/22/15 Everything is here now, I will start working on the box here soon. Box has been built, 2.3cu, 33hz tune.

I know a decent amount about car audio, but never have I installed a subwoofer this powerful... im wondering what i can get away with. I will have one 15" contralto 2500w rms, a mono amp 3000w rms @ .5ohm (its rated to handle that). Now I will not be bumping for hours straight, probably here and there. Im wondering, if I bought a XS Power battery wired with my factory, and given they are fully charged, with stock (130a) alternator charging, can i bump for a little bit and then give the batteries a rest after a minute or full song? I suppose i could try it and watch my voltage...basically how long can a strong AGM battery last to supply power with my settup? I know a HO alternator is my best option, im just wondering if there is another option i can get away with that will cost less $$ for my scenario. Ill hear from the pros.

Hey guys, I need some help... I have a 2002 chevy 1500 ext cab and Im trying to build a high-end system in it. Im only 16, so its a big project for me... I got my truck last august for my birthday, and my parents bought me a HU, and some door speakers on a little amp. It was great, but I knew I wanted at least a single 12 in there. I went with 2 12's in a under-the-seat box. 2 alpine r 12's on 2 rockville rxd-m4's in a ground shaker box. It was cool, but I just kept wanting to upgrade, so I sold one of the amps, and put a sundown 1500D on both the subs at 0.5ohm. It rocked, and still does 2 months later. I want more... the 6.5's and the 4x6's dont keep up with the subs, and im upgrading the subs anyways, both my dad and uncle want sound systems in their cars, and im selling them each one of the 12's. Im deciding to go with 2 sundown x15's on 2 sundown 1500D's. Big money, i know...... Audio kinda sucks..... I have a box designed in sketchup for the subs. I realized that even with the 4 speakers ive got now, they dont really keep up as well as I want them too with the 12's, so I know they wont keep up with 2 15's on 2 times the power. I am keeping the door speakers ive got now, but im adding 4 crescendo pwx 6.5's, i found some kick panel replacements for my truck at an audio store that was closing near my house and got them for $30, what a steal, theyre like $200 everywhere online. So I want to move the alpine 6.5's into the kicks and put 2 PWX 6.5's in each door... Is this possible without too much modding? The little pods in the doors now house a 6.5 and a 1.5" (i think) tweet. Id LOVE if I could fit the 2 6.5's in that little pod without messing anything up or having to mod too much. Any suggestions or help is greatly appreciated. Thanks guys, Trey

I am trying to decide between two amps at the moment. my current amp is the crescendo 2200w and the amp im looking at is the soundstream 6000.1. i'm planning on doubling my system so my choices are get another crescendo or get two soundstreams. the company i work for can get a really good price on the soundstream and it claims it'll put out more power then the crescendo. i just wanted to get some opinions on what would be the better amp, Thanks guys!

browser keeps crashing so this will be done in sections. Let me start with saying this build was done in the sub 20 temperatures with occasional snow showers. I only had 3 days to complete build due to long work hours so it was kinda rushed!

I have (2) BRAND NEW IN BOX Crescendo Encore 12Ks. Never been powered or mounted. I took them out the box to inspect for shipping damage and the immediately stored them. Pics of mounting tabs and power inputs for proof that they have never been mounted. I also added a few extra decals on there. $2100 Shipped or $4000 for both Shipped They were bought a few months ago for a build that ended up not happening. Literally BRAND NEW. ***NO TRADES***CASH ONLY***

Hoping some of you can offer some insight or first hand experience. I blew my Rockford R1200 amp so I decided to go bigger and just got a crescendo bc3500. Planning on an xsd3400 under the hood, and maybe an alternator depending on what voltage looks like during testing. I've been somewhat out of the game for a while so I need help deciding what subs to throw this kind of power at. GOALS: 2 10" drivers 2.5 - 3 MAX cubic feet box Musical but with authoritative lows (will be using them primarily for electric funk hippie rave music, rap, and soft rock) Reliability/durability to handle 3k+ (on 2) Subs will be in the boot firing in to the cabin and probably sealed off with some form of ghetto hackjob. So far I've looked at the Sundown X, SSA Xcon, SQ HDC3, and Crescendo Contralto, they all look good from reviews, but I haven't modeled any yet though. I'm sure i'm missing some beefy 10's out there in the 1500-2000 rms range, help me decide! P.S. no idea what my old username was, havent been on any forums in years so I might look new but I promise I'm not
