Hi everyone, i was upgrading my cars electrical today (big 3, new 175a HO alt, Kinetik 1800w batt) and when I was done installing it and I turned over my car, I was running 13.8v. When I started playing some music, it sounded like it was quieter than when I had stock electrical. All the lights in my car were dimming and the volts were dropping as low as 10.5v. The alternator was charging real slow and having a lot or trouble keeping up. What could the problem be?? I am absolutely clueless on what it is so if anyone has a good suggestion, I would love to hear it. Thanks in advance

Does anyone know what the accurate specs are for the sundown audio SAZ 1500d v.3 is? I lost the paper work for this and i've found 2 sites that claim to have the specs but they are different from one another. I'm just trying to figure out the accurate inline fuse to use and the accurate watts.

I installed a audiopipe 1500 to power a sundown x10 in a ported box. jl audio componants in the front doors jl coaxials in the rear deck running on a jl700/5 the 2012 mustang gt factory hu and lastly the pain in my back is a audiocontrol dq 61. I mounted everything on a wall behind the rear seats just in the trunk. I 2 separate stinger 1/0 for power as well as grounds. My signal is also stinger 9 conductor w/ 2 350amp fuses. the 5th channel on the 700/5 is waiting on jl8w3 mounted in the front doors. I hope there is something my eyes are not catching because the insides sound like tin cans. when I am able to improve the sound I cant turn them up beyond 25% without clip…

hi, i have an alpine 9887 hu and also a sax100.4 and a 100.2 and here is what i want to do. an active front stage using the sax100.4 as the processor not the 9887 and have 2 eu700 in the back off of the sax100.2 with a 400 hz lpf for midbass ( already have them so no changing of that) and i need to know would i set the crossovers on the 9887 as a 2.2 3way or a 4.2 system since u have to take out the unit and move the slide i would rather ask then experiment since it is a pita to take out the head unit in my car. and also would it be a l=r or l/r and also i am going to be having subs too that is why the lpf is kinda of high.

I've been looking for a big 5000 or 6000 watt amp kit. Do they even sell any kits like that, or do I need to buy all the wires and cables ect. separate? I'm running an Atomic AT-5000.1D I'm looking to buy one of the best amp kits to run with this amp. Basically because, I paid all this money for this amp so I don't want to get a cheap amp kit. But you know how that is. Thanks everyone!

Well, instead of posting all this in the build log, i'll just post it here because i have a question anyways. I have\had 2 of these amps strapped together. When i first strapped them up, after several minutes, the slave went up in smoke. It was concluded that the input stage on the amp got damaged. There was no audio coming through either amp when i first tried using these. I tried using just the master. No signal at the time until i unplugged the rcas from the HU then plugged em back in... been working ever since, odd but no probs now. Got the slave amp back in and i did not have any subs hooked up to em when i had em strapped again but the slave amp went up in smoke …

it was sounding to good to be true. didn't know if these amps are ok. wanting to put it on 2 l7 kicker 15. thanks. saw it on on line car stereo.com

hey everyone, so today i went to harbor freight tools, got a DMM on sale for 3.00 dollars, the name brand was cen-tech, heres the link CEN-TECH MULIMETER so anyways i got home, logged on, looked on the stickies for the Setting gain with DMM tut and i done everything i was suppose to, minimized HU Settings,bass,treble,etc, used a 50 hz tone 0 db, and when i connected the DMM to the speaker output with no load, i had to set the gain almost at 3/4 to get my voltage i have a hifonics bxi 1200 watt amp at 1 ohm load on 2 12" pioneer 308D4 rated at 400 rms per sub HU is kenwood MPC205, 2 volts at sub pre-out 1200 wrms at 1 ohm load so 34.64 Volts is what im striving for on my d…

yeah, i know, not the best amp by far, but my cousin's truck go broken into, and his audison srx3 will be out of the picture for a little while. we have a powerbass asa 400.4 sitting around, and want to use it until we can get a new audison. now, for the big question... does anyone know if the powerbass in tri-mode capable/stable? we want to use channels 1 and 2 for the comps, and bridge 3 and 4 for a sub. a 15" dayton titanic mk III will replace the 12" type r that was in there, although a type r will be back again... probably. full system rundown 2000 chevy s10 ext cab clarion dxz775usb hu audison srx3... now gone diamond d6 comps in the doors, textile tweets, +3 to…

Hello, im thinking of getting some new amps for my system, I am really interested in these Crescendo amps, for the price dont seem too bad. I was wondering how the sound quality is on these? My subwoofers are FI q 15, two of them in a sealed box. My mid range speakers are diamond audio hex 6 inch tweeters are Dayton audio R528F-4, 4 ohm silk Alpine cda-117 and pxa-h100, going 2 way active front stage my amps i have right now are 2 ppi pc2600.2 for the front stage and a crunch gp3000.1 pro amp for the subwoofers, i have had the ppi amps for 12 years, realy like them, very clean sounding amps, i was wondering if the crescendo C1100.4 would sound just as good as the ppi? i h…

i just installed an excess amperage 300 amp alternator ... for some reason something is not working correctly ... i am only getting 12.5 volts and it drops a tad to 12.4 when i rev it up ... what is going on ... the stock alt was connected to the fuse panel but i ran the new wire to the battery and fuse pannel to the battery

I was wondering if anyone on here uses or dislikes the powerbass xa3000 and if you use it did you have any problem with it. i already have an orion 2500d on my sub but i also have had this powerbass sitting in my room because it was in protect mode and a local repairer said he couldnt fix it. i just want to see if its worth fixing i only bought it for 150 bucks and would it be better than the 2500d?

ok ok so my very 1st amp was an alpine 1507 yea hot shit right, but i neva got to hook it up cuz my bro sold it, cuz i neva paid him back... but the guy he sold it to is selling it again.. and ha i'm buying it back for get this 80$ and the amp dam near cost 300$ soooooo, now i got a jbl 1200 and an alpine 1507.. for those that dont know thats 1200 watts+ about 1500 watts totalling at about 2800watts RMS but i only have one sub, and i need a new alt now that can pull about 300amps...

I never got around to finishing the system in the last truck but this one will be different, dammit. Anyway... New truck is an F-150 Supercrew. The H/U is already installed, Kenwood DNX-8120. It has some limited processing capability but I doubt that I'll use much of it. I have an Altomobile Drive 30 for processing the front stage, I'll replace it with a MS-8 if I decide that it isn't getting the job done from a noise perspective. Front is going to be 3-way active, HAT Legatia 3s and 1s in the kicks and some midbasses in the doors. I have a pair of CDT ES-06+ woofer that may go there or I might order a pair of Dayton 6s for each door. The rear will have a decent pa…

so my friend is wanting to get a batcap becuase he heard it will help out his electrical ALOT. what do yall think about it? ever had one, used one.. etc

Are the zapco SP7-SL and arc audio PEQ 1/2 din mountable, as in can I mount them under my denon HU in my 1 1/2 din dash? If so, how would I go bout doing this? Just take out the pocket and slide in the eq?

In the market for one. so far have looked into db, irragi, cbr electronics, nations, mechman, and just recently spring hill. I've heard of people having issues with mechman and irragi but after doing some reading there could be other reasons why their units failed. Any input on any of these? right now I'm leaning more towards spring hill autoelectric simply because they offer more options for upgrading ie i can order just the parts i need and upgrade the alternator myself and save $100+ that and their customer service has been very responsive about answering my thousand questions. even on the weekend which i thought odd... Anyone have any dealings with them either??

Never ran active in my life so I have some questions Amp is a SAX-100.4 Comps are the Cresendo CCX65. They are rated at 100 rms a side. Doing this passive is easy, but I am wondering how to split the power levels between the mids and the high's. 50/50? 75/25? Or even 99/1? (heard the tweeters are kinda bright lol) When setting gains if I want say 75 watts on the rear channels I'd play 1000hz test tone. Hook the dmm to 1 rear channel and turn the gain till the dmm reads 17.32 volts correct? So that should be 75 watts per channel. ( 4 ohm load ) I plan on crossing the mids and highs at 3000hz, so should I still use the 1000hz test for setting the gains on the highs respect…

Hey I just made an all new setup in my car. I have 2 skar audip vvx 12s in a 3.7 ft box tuned to 34 hz running off a crescendo bc2k. I have a 100 amp alt not sure if its stock and a northstar agm battery. its pretty much an xs3400. I aslo hace the big 3 done in 1/0 gauge. The setup is alright but it just doesn't slam as hard as I expected. I used to run one of the vvx 12s on a kicker zx1000.1 with the gajn and bass boost like 3/4 up and bassboost and loudness on on my deck and it would slam just as hard as these do now. Iy did burn the voice coil after about 2-3 months though so I learned my lesson about all yhose settings and clipping. Now I just use the bass knob wit…

I am going to be getting my subs back this next week. I have 4 8's a 2000 watt hifonics brtus amp. with i believe 8ga wire with a optmia red top up front. would a cap be the way i should go or would another battery be better.

I have an alpine mrv850d. 2ohm stable, but i just ordered a pair of d4 subs. so i can run them at 1 or 4. what will happen if i run at 1ohm? i know i ran my hifonics goliath and ED 9.1 below 1ohm with no problems. randomly my 9.1 would go into protect but if i shut it off for a second it was fine. but ive never owned a Mainstream amp like alpine

Tested voltage drop with most accessories off last night. At idle the car rests at 13.9x, With a variety of music and an Iasca test disc, at the loudest volume i can play the factory stereo at while still sounding decent, the lowest i got it to drop was 12.69, it was mostly between 12.7xx and 12.9 on HARD hits. Electrical system is stock, battery, alt, etc, all stock, no cap/ 2nd battery, extra 0wag ground under hood to battery, extra 4awg ground running to rear of the car where it joins the 1/0 that goes into my amp. Amp is an MTX 81000d running @ 2ohms, Rated 1krms @ 12.5 volts, most people get between 12xx and 14xx on their birth sheets at that voltage. I was just surp…

Anyone have the dimensions?

I recently installed a Pioneer P4300DVD doubled-in deck in my truck and just have a few questions about some settings. 1. What should my sub frequency be set at on the deck (it goes up to like 120hz I think)? 2. What should my HPF be set at on the deck? 3. Any tips on tuning the Custom Equalizer settings? Just some info on my system I will try to give the whole run down in case its needed.
