Amplifiers / Head Units / Processors / Electrical

I just got my 2500 and am wondering if my planned battery expansion will be enough to really get this amp going. This is my 1st experience with sundown product so I would like to know what other owners have done. As far as electrical goes I've got a 220 amp alt., big three, and an hc2400 along with a standard battery. I'm looking to change batteries to 2 xs3400's piggybacked with a xs680 with each one. Two runs of 0 awg. Will be running a yellow top upfront. That maxes out the space I've got to use. Will this be enough to power the amp up to be able to get enough power to compete? Is there a better configuration I could run? All advice appreciated! Thanks

now i know how to mod the MTX 81000D, but i was wondering if anyone knew, to mod the 1000D to run @ 1 ohm, is it the same as to mod the 81000D?

Well, I have all the speakers that are going in my truck, however, I lack the power to get them up and running. I came across a thread over on CA.com that linked me to a memphis amp called the "mch1300". I don't know much about memphis products, but that's beside the point. My question is this, instead of having to buy a lot of amps will this power the following: 2 image dnymaic cx62's @ 2ohm so they should get 115 watts, 2 koda 8's they are 4ohm so they should get 75 watts, and a eclipse ti, it's DVC 4ohm so it should recieve 600 watts. Is this correct? That would mean I would just need to get an amp for my horns and I'd be set. Also the kodas, really won't be get…

Was drivin around testin out new speakers and was turning up the volume, and when it hit 29/35 everything just shut off. So i figured I blew a fuse. I checked the fuse box numerous times and the fuses are all fine. Took out the HU cuz a buddy said there was a fuse behind it... nothing... I have no clue where to go from this point.

I have been debating on how to ground multiple runs of 1/0 for my upcoming install. So I figure weld some 5/16 bolts to a length of steel channel bar, then weld that to the body of the car. this would give multiple point fors grounding and I wouldn't have to rely on screwing ring terminals to the sheet metal and risking it coming loose.

Alright so I have a 95 Saturn sl2. I as wondering what to do with my power cable because I cannot fit It in between the negative terminal and the actual battery. So instead I have my power connected to my fuse box which..in my mind is putting so much less power and just not as hood as the direct connection to the battery. Is there like an extension to my terminal I can get or what should I do about this.. Sorry for bad Typing..using my phone

I have a Soundstream TRX 2.550 and I need to properly set the gains for my subs. I checked the sticky in this section and it says to use the frequency that the bass boosts uses. My boost is +18 from 35-80hz. So what tone should I use?? I wish I didn't have to use the Bass boost knob but I have no other way to turn the subwoofer level down as I am on a factory stereo. If I turn the bass down on the factory stereo it turns the bass down for all speakers making it sound bad. Thanks

From those who have experience with these batteries- I need a total of about 4000 worth of their model numbers... For instance 2 hc2000s or 3 hc1400s, get me? Ok, i got a small area to put batts in, i had emailed them asking if i'd be all right if i ran 6-7 HC600s in the back... They told me no, it wouldnt last that long before they were completely discharged. They said the HC600\800 are like large caps, not long-term batteries due to their short reserve time(too bad they dont post reserve time on their site!!!) So, i called them up just now and got ahold of someone on the phone who sounds like he has less experience with them than i do... so i come here. For daily driv…

With a pretty significant build on the horizon now steering towards higher end equipment, i still am not ready to part with my factory head unit unless it becomes an absolute must. I prefer the OE look and like the fact that my navi and bluetooth are integrated in the setup now, although i know that with a little tweaking i could likely make them work with something different, if needs be. On the G35 w/ the Bose system, all the processing is done at the actual factory amp. The leads running from the factory receiver are low level already and many people prefer the results with the RCA cables spliced/soldered into those leads over using an LOC. I myself initially had used…

hi im new here dont know much bout car audio but was wondering what u all thought bout the SAX-100.2 amplifier

who was askin 4 HU advice ??, sorry i couldnt find ur thread hey thats the pioneer am talkin about DEH-7650MP sorry at the begginin i told ya its DEH-7560MP i wasnt actually awake, pre amp out put is 4.5 to 5 volts not really sure,

I am posting this topic for a friend. I cannot figure out what is wrong with this thing. Here is what is going on. Voltage remains steady. When subs are off the front speakers do not cut out reguardless of volume. When the subs are on the front speakers cut out at higher volumes. I disconnected one speaker at a time at the amp and ran each speaker separately and they front left cut out when connected and the front right cut out when connected. I checked all the connections near the amp and everything seems to be fine. The gains are also set below normal. What could be wrong? The amplifier is not bad because it would have cut out with the subs off.

need like 2500w rms for the mt like 240ish (i guess?) @ 3 ohms for the pro60s. im most likely not gonna do rear fill, if i do, itll be off the HU. what you guys think? im tryin to get the amps ordered, so then i can start the box/amprack.

sooooo heres how the story goes. i got an amp a while ago, the crunch gp 2500d, and then i bought some subs, like the aq sdc 2.5s, but take a little more power (called TF X's if anyone is interested) both dual 4's wired down to 1 ohm at the amp. anyways, i'm underpowering them by a few hundred watts, and i'm looking for a replacement. in my searching i as offered an earthquake ph-d3 for a bit less than 300 rom a friend of mine, but i think he used to use it for spl comps a few years ago. anyways, the amp works great, and at 1 ohm does 3000 rms, so i figure if i'm easy with the gain i'll get the output i need, or i can match my current output at 4 ohms with 1300 rms. m…

does the remote on the rockford fosgate t1500.1bd useful, or should i avoid it, and if possible, can u tune it or adjust it, like a gain knob thanks

My system was finally working right all together. I was on my way to my apartment (3 hr drive), so I had turned the bass really low so it wouldn't knock my radar detector off the glass. I was just driving along and heard a loud bass hit all of a sudden. It was really weird, kuz the bass was pretty much to where I couldn't even hear it and I guess I didn't notice kuz i had turned it down alot. So the bass hit really hard, then stopped. It did this about 2-3 times, just really odd sounds and extremely loud...like not going with the music that was playing and far far louder than I had the bass turned up. Anyway, I got home to check it out. I can turn the subwoofers OFF…

I am thinking about getting a Sound Stream Xstream 480.2 and 360.2. I know that some of the older Sound Stream amps were really good. But is this like other "ghood back in the day" companies or do they still make strong products?

my question is im buying 2 fully loaded 12" fi btl's i was wondering if the sundown SAZ-3000d would be enuff power for both of the subs or should i get 2 straped i was only looking to get exactly the rms watts or close as possible or really just enuff power to make them hit nice so any advice would be greatly appreciated!

ok well in the mini cooper, the back windows are tinted with 5%, plus will be covered completely anyways, so NO sun at ALL will be coming in the back hatch area where the amps are. they are those MTX TA amps, they have that "xtant" cooling thing or whatever, where it sucks air in the front, and it blows out the sides or something like that. well, since its gonna be walled off, no a/c will be in the rear...i basically wanna throw a few fans in the back that come on with the headunit just to have airflow back there....and i dont mean a couple little PC fans...any ideas? something that wont draw hardly any amperage either.

Welp, I ordered a crescendo bc2000 last night!!!!! Should be at my front door by Monday!! Anybody have one of these? What do they perform like?

Hi guyz, Thought I would share this. BRAX from Germany, HELIX Big brother company has/will release.d a new amp. If I understand correctly, it will be a power amp: No Crossover. A german magazine has tested one; specs as follow: MATRIX X4 @13,8V: 4x292rms @4ohm (drawing 136A) 4x270rms @2ohm (143A) 4x284rms @1ohm (186A) Damping factor: 694 @100hz 592 @30hz Size: 330mm x 75mm x 330mm Which is around 13" x 2.95" x 13" (tiny isn't it?) Price: Well it's a BRAX...

ok i know there is a topic here somewhere on this but i have searched using keywords and didnt find what i was lookin for. i would like to know what are suggestions to correctly power a sundown 3500. it is not s competition vehicle jus a daily driver. the speakers will be 4 fi ssd's ( i already own them) run @1ohm. most likely this will go in my ford escape which already has 0ga upgrade, kinetic 2400, batcap800 for electrical. i know i need an alt so i will get probably one runnin at 14-15v 300-400a. i might only compete once or twice but this is just for me to blurr my vision when i'm feelin it. how many batts should i add after i get the alt?

Driving a 03' bmw 325i sedan, have a JVC KD-AVx77 and it doesn't fit. The dash kit I purchased doesn't even fit it. I also think that the panel that goes over the dash kit doesnt even fit the unit either. Anyone know what I can do? Am I going to have to customize it?

Like the title states. I need an amp to power 1 incriminator audio lethal injection DVC 4 ohm sub 600rms. I want something that's reputable and not something that is going to take a crap like that China stuff (no offense). Brand/ model names would be great, I know this isn't the 4 sale section but if you're selling something that's good and suites my needs, PM me with price, brand/model name, and condition THNX to all

I will be running two batteries for the first time and have some questions. I have an energizer battery under the hood, and a yellow top for the truck. My question is will these two be ok ran together? I thought someone told me the batteries must be the same, but I could be mistaken. Thank you for the input.
