I'm kinda debating whether I should go with a Rockford Fosgate 2500-1bd for my 2 Fi Bl 18"s or should get 2 Rockford 1500-1bd what you guys think? Can the 2500 have enough power for them 18"s or will I have to buy 2 1500??

So something came up and I have to wait a week or so to put in my dc power 270xp... I'm going to be running a saz-3500d @ 1.33ohms and sax-125.2. I also have 3 optima yellowtops (i'll get some xs or kinetiks later).. Could I get everything setup and run it off my stock alt? I think it's either 105 or 130amps..I obviously wouldn't abuse it and monitor my voltage..It would only be for about 3 or 4 days.. Thanks

having trouble with engine noise plz help if anyone knows the problem.. everything is wired correctly

Hey all I am new here and semi-new hooking up car stereo... that being said I need some help hooking up my new Sundown 1000d the manual says for 1-4 ohm 1 speaker configs to use both positive and then runs a neg line fom the woofer towards the amp... notice i said towards... the positive leands stop on the positive terminals of the amp but the negative lead routes toward the amp and then stops.... Im a newb I know but Id rather ask how then to tell you how I burnt my truck down or fried my brand new amp!! thanks in advance.

Just getting into car audio so be kind. I have 2 dvc rockford fosgate hx2 10's (500rms) Sealed 1.5cf box. I know these amps are overkill but eventually I will be upgrading my subs. Ive narrowed it down to 3 http://www.sonicelectronix.com/item_23550_Hifonics-Brutus-BRZ2400.1D.html on my local clist theres a used aq2200 for $300 Sundown Audio SAZ1500D V1s for $275 Id consider the crescendo 2000 but its on backorder.. I'll also be doing the big 3 upgrade. I can add a second alternator and battery if needed, but i dont 'think' ill need to get that serious yet. Right now im more concerned with sound quality (I listen to alot of rock) than I am with brute force. But i think…

What do you use to islolate the front & rear battery??? ...should I use a battery isolator; or, will a high power relay work ok?

What car do u prefer for hit more db? A Toyota Rav4 2005 or A Toyota Tacoma Extra cab 2005 My system is 2 TRF 12" and 2 T20001. what car do u prefer for competition and hit more db

Anyone use either of these to intigrate a system to their factory HU. I have a new truck (2004 FX4) and want to keep the factory indash 6 disk cd player but want to install my Arsenal 10 CDT comp set and ppi amps. I just don't think that the factory bass treble is going to cut it for tuning though. Any thoughts (hopefully from others with a similar situation) thanx in advance

Hey all.I just got my high output alternator and I'm wanting to do the big 3 upgrade but I have a couple of questions first.I'm going to use the knukoncepts kolliousis flex 1/0 wire to do it and I was wondering about how many feet of wire I would need to do it. My car is a 1977 oldsmobile delta 88 with a 403 engine if that helps any. Also could someone post a good article on how exactly to do it please? Thanks a ton. HawkEye

I just recently purchased a hifonics bxi1608d. It has 4 gauge terminals and is going to be pushing about 1600 watts. I am not sure if 4 gauge is large enough for the 1600 watts but, on the other hand, I am not sure if I would be able to squeeze the 2 gauge into the 4 gauge terminals. Any suggestions?

Hey quick question guys/gals I have an optima yellow top i just recently bought.... 34/78 I know others have mentioned hooking there bat straight to the cars battery (parallel if you will) without any problems, YET on the optima website it states: 9. Can I hook an OPTIMA up in parallel with my other battery? No, when hooking batteries together in parallel they should be of identical make, model, and of similar age. So can anyone confirm that there is no harm in hooking my optima in parallel with my car stock battery? tried to search this but found no info

well after a long and painful 8 months of design and thought----Pioneer P9 combo is what I have decided on. just letting you guys know----it shouldn't be too much long till I am dropping pics all over this forum of the install.

Well yesterday my dad was helping me run some wires in my car and decided to shake the hell out of my amp. When he did it ripped out all of my speaker wire connections and everything. So i reconnected everything and checked my connections everywhere but the amp is still not working. My dad is thinking its my RCA splitters. What i was wondering is there a way to test my RCA's with a DMM? Also would a violent shake make the amp quit working? It powers on theres just no output. Any help would be greatly appreciated.

I hooked up a system for my buddy a year or so ago.. Just 1 Treo 12 and an audio pipe ap1500. Stock electrical. All has been good till yesterday.. His stock battery took a shut so he replaced it. Called me up to help him adjust the deck back where it was. I went through it and when I began turning it up the ampoules cuts out. Goes into protect for about 4 seconds and keeps on playing for another 5 seconds or so and does it again UNTILL I turn it down. I lowered the gain a little bit out of curiosity but same thing.. What can be causing this? Where do I start? This was a used amp when he bought it on CL so maybe the Amps taking a shit? Any help is appreciated.

ok i have 6 xs d3100s... im gonna charge them all at once cause i dont have access to each battery.... now last time i charged them i used 2 amps which took forever!.... can i charge them with 12 amps ?? i have a schumacher charge that shuts off whens they are fully charged (trickle charge) and doesnt charge higher than 15 volts.... the charger has a 2 amp, 12 amp, and 75 amp charge setting..... the 75 amp is for starting a vehicle with a dead battery..... so i know not to use that one lmao... will i be fine charging with 12 amps ??? this way it wont take days to charge them.... last time using a 2 amp charge it took about a week lol...

I have a 2004 Hyundai Sonata GLS 2.7L V6 and it comes stock with a 90amp alt BUT Im pretty sure if im running 2 15in Fi BL's ill need one right? I bought a Soundstream 1000amp hybrid capacitor but I dont know it that wil be enough if im running those speakers on the Kicker zx2500.1. Just checking with yall to see and make sure... dont wanna mess up anything you know? If you guys think ill still need one do you have any suggestions? I checked that Irragas store but they didn't have one for my car =(

Ok, a guy at my trade school let his cousin use his JL A1400 amp, suposedly the cousin sprayed WD40 in the ground connection, why i do not know, and now he says the protect light comes on, i kow hes not the smartest fella and might be hooking it up wrong since he has it back now, he brought it to trade school looked at it, it was fine so he brought it back and it worked, then protect went on again, now hes getting his cousin to buy him a new amp, and he wants to get rid of this one, he brought it for me to look at but neither me nor my teacher can find anything wrong with it, and he wants to sell it for $75, what do yall think?

okay so i have done a search on this all over, and i did find one post about someone who only used the front channels and then connects the rear channels directly, but kept the fader set to the front, but this just sounds like a bad idea what i want to do is amp my front speakers (alpine type r components), but leave my rear speakers on the head unit's power (alpine sps-400's) i just bought a rockford fosgate t400-2 off a friend on the cheap so i was planning to use that (type r's with only 17 watts have absolutely zero bass) head unit is sony-gt240 ( i know sony isn't that great, but the sound quality is just as good to me as it is on some friends alpines and pioneer h…

When I installed my Massive P1000.1 amp, I also got a 2 gauge Amp Kit that came with a 80A fuse. I just read the Massive's owners manual, it recomends a 60A fuse. Does using a 80A over a 60A make any difference? When I had my system running, I had the amp powering a SI Mag @ 1 ohm (880W).

ok i just got a new 9855 with 4 volt preouts and a used merlin m41 from flakko, and i go the 9855 to work, but when i hook up the amplifier, nothing, not even the power or protect light came on, but then today outta nowhere when i turn on the car, i hear this semi loud click noise, and the amp turned on and i could listen to music, but wasn't very loud, even at 20 volume. it then proceeded to shut off again, and now has no music coming from the speakers, and the amp's lights (power/protect) are off as well. i had this same problem with the last amp i had, before. and im sure when i put that one in it will have the same problem. anyone have any ideas? and i have speaker…

I have a Ford Expedition 2007 I want to apply the Big 3 to my car. I would like to know how many Ft of 1/0 Knukoncepts power wire will I need. Maybe 10ft? Dont really want to have much left overs...
