amp efficency HUGE fues rating differences recommended
acmobiledodge posted a topic in Amplifiers / Head Units / Processors / Electrical
i work at a shop and have a customer who wanted to buy a large power amp. none of our main dealers have anything in his wattage range. so.. down for sound has a JP53 that calls for 600 amps of fusing... then we have a tara amp thats calling for 209 (music) 419 amps sine. both claiming 5KW of power. 120 - 390 amps of difference is (any way you slice it) a massive change in electrical system demand. why would anyone buy a ...? is tara incorrect? bottom line - im digging into efficiency numbers that ive never really had to care much about when working with 500-1500w JL and rockford amps... -
Hello all I have a 2015 Silverado crew cab and I finally have the funding to play a little my goal is to have a 5k amp and 2 15s subs in ported box, the whole back cab will be sacrificed. I need to know if a 250a alt and a good batt would be sufficient for what I’m looking for or maybe that and an extra batt? Also I keep reading about this donut deal on my negative battery cable that regulates alt voltage, and that it’s a pain to get around? I haven’t dug too deep into it, but i wanted to start with at least a big 3. Any help would be appreciated. Thanks

I've had my subwoofer installed for just over 2 years now with no issues. Now when I start my car (No music playing) The power light on my bass knob flashes and I can hear my subwoofer slightly thumping. I've checked the ground and the power cables but can't figure out what causing it. The clipping light doesn't flash red, just the power light. I attached a video of this. You cant hear the thumping because its very low. The amp I'm using is a Sundown SAZ 1500D and I'm using the bass knob that came with that amp. This issue will happen almost every time I start my car but last week it stopped for about 4 days and now its back and even worse than it was before. Bass Knob Flash.mp4

Whoa! That's a big subwoofer! Whats the deal with McCauly? I just looked up their site, and they look to have some products, but not a ton.

Man, what a nap I had! So, how has everybody been? I have some boxes in my garage that have been around for awhile. Might revisit and use a few things. It’s nice to be back! TheHammer -
The Adcom sub amplifier

Subwoofer almost done. It ended up being pretty big. Internal volume is 13 ft3 tuned at 18Hz.

Help Bad voltage drop

Try using a battery isolator. It will keep the engines battery separate from the audio batteries and allows the alternator to charge you audio batteries without reverse draw -
Advice from you car audio experts needed lol amp for two l78

The DS18 pro 3k is around $300 or so. Williston Audio bench tests show it makes true power certified. -
I’m looking to build a ported enclosure for (6) Ampere Audio AA-2.5 6.5” D2 subs. They will be run on a 5k/1 ohm stable amp wired at a 1.33 ohm load. There will be plenty of power as they are 500 rms and 800 max. I can’t seem to get anything from Ampere Audio on the port size I need. With sub displacement my box needs to be 2.48 CF (+) port displacement. Does anyone have suggestions or know how to calculate the port size? Square inch and length is what’s needed. Hopefully someone can help on this

Finally getting around to designing a H/T for our new house. Substage will be a McCauley 6174 in a 12ft3 4th order vented at around 18Hz powered by an Adcom GFA 555. I picked a clean Sony ES on Facebook Marketplace for almost nothing. Front L/R and rears are Paradigm in walls, their reference series, should be pretty good. For the center channel I designed a large line array with 2 sets of 5 drivers in Bessel arrangements flaking a Peerless 1 1/8” dome. Hopefully I’ll have some build pics in the next few weeks. I am really looking forward to the sub stage. I have used the 6174 in many pro audio builds before, but not in a small H/T.

Hi guys I'm new to the forum and this is my first post. I just started out building my own boxes for the past 2 years now and need some assistance on this new build. Attached is the pictures of the box in progress. Can anyone assist me with port tuning (I'm from south africa so in cm would be great). The dimensions are : Height 41.5cm Length 90.5cm Width 45.5cm Sub mounting height 17cm All wood is 20mm plywood What is my current port tuned at 52.5cm port running in an L shape in the box 5.4cm width Length 41.5cm pictures attached The sub mounting height is basically the walls around it. Thanks for the time

So I decided to finally put my two L78's (4 ohm) to use on my new blazer rs. The thing is that im using a shitty "2500 watt" power acoustik amp. What amp should I get? Ported box. Under $300 because it's pretty rough out there these times around. I also have the lc2i installed... if that makes a difference. Thanks! -
Thanks. The issue is some music just doesn't sound good in ported boxes. Rap hip hop dub step, boomy music with low basslines and baselines recorded -5db and less sound best. But some genres of edm like trance...I've never ever heard it sound good on a ported box. But in sealed...it's a night and day difference. Sealed you get tight accurate kick drums and fast bass notes even if the track is recorded with a -12db and 63hz baseline. In fact. The only way I was ever able to get genres like trance and other edm genres to sound proper in a ported box is by using an epicenter but that device creates a weird type of wobbly bass if that makes sense (for those who use the epi they know what I'm talking about). I really miss the musicality of a sealed box and being able to play almost everything nicely without having to eq the shit out of it. I'll wait for Aaron to chime in. Thanks

I would do the Icons as Ive had them before but ported, I'm sure they would do well in a sealed application. The Gcons would work as well, hopefully Aaron or someone responds to help you further. Both would work and sound great. I put my IA Lethal Injections in a sealed box and they sounded good but sealed just wasn't enough output for me, but we have different goals. All are great choices

HI, Ive been trying to call the ssa store phone number for days but no one answers. anyways, i am looking to buy 2 12s for use in a sealed box. I have been told to get the gcon 12s. my power is around 2000rms. I do want them to hit a low f3 in a sealed box. do you recommend the gcons? whats the f3 point for 2x 12 d4 gcons ? what size box is needed? i also heard the icons are good. what do you recommend for subs that will hit low and hard and work best in sealed boxes? and is shipping within the US free? i appreciate your help and recommendations. the subs dont have to be SSA brand just anything that is around 1000rms each that will sound best in a sealed box. thanks
