I ordered a hifonics zeus 1800w amp. The spec sheet online says it uses 4ga inputs. I feel like 4ga is rather small for an 1800w amp. I know I can get wire reducers, but could I just run 2 fuse holders, and on the rear at the amp go down from 0ga to 4ga? Or should I just run 1 fuse, and solid 1/0 run to a reducer?

i have two fi ssd 15's running at 600rms each on a pheonix gold 1200.1 and it just isnt pounding enough for me i wanted to give the fi's a little more so i was looking for a new amp. i wanted to give them anywhere from 800-1000 each. i came across an amazing deal and got a brand new opti4000d which retails for about $900-1200 and i got it for $300. i just couldnt pass it up.. i know there are mixed opinions on the opti's but for the most part i hear they are decent. now heres the question.. 3000 watts at 2 ohms is too much to give to my ssd's. what do you think i should do? im totally down for new subs.. or i can sell the opti and make like $500 for a new amp. i love the…

I currently have a Kenwood KDC-248u head unit and I think I want to upgrade it to something a lot better. Not exactly sure what hu I want so I am looking for some suggestions. Budget is $400 but I definitely would like to get something cheaper if I can. Thanks -JP

believe me i know this is a stupid question but i had an argument with a guy from a mechanics shop and he doesnt believe me: if you have 2 DVC 1 ohm subs wired in series then together to come to a 1 ohm load and run that to a monoblock amp that is rated at 1600 watts rms @ 1 ohm, does that mean each sub gets 800 watts each or do they both get 1600 watts?

I don't know a ton about car audio and was wondering if maybe someone could recommend an Amp for the Mag 15" that I just purchased

Just installed my cda-9886 and it plays the radio but on cd's it shows that its playing but no sound. Same with ipod. I'm thinking it has to do with it possibly beig a faulty cd player... which is ganna piss me off. Any ideas?

I currently have a Mechman 270a in my 2004 Dodge Neon SRT-4 and it's going through belts like crazy. I have checked pulley alignment, tension, and have done everything I can think of to solve it. This only happens when the alternator is under a load when I play my beats. I have roughly 600 amps of draw with nearly 12,000 watts of battery reserve. It does the squealing the worse at idle, and actually tears these belts at higher engine speeds. I use the good Gates belts, but they don't last more than a few weeks. I have had trouble with this alternator several times and had to send it back three times, and swapping these belts, and especially the alternator in my car is a H…

Who can I talk to about having a Treo 750.1 fixed, I've been told THE fets are fried.. I'm not 100% sure if anything else is fudgeed or what, but I'd like to see how much it'd be to get fixed, rather than buying another amp.

With the Alpine cda-117 do you have to buy the H100 imprint to use the deck active? If so can someone with this set up give some imfo or review.

So i checked today my battery voltage in the manual, its said it was 12.8v fully charged, this weekend into the week i am going to try and get a voltmeter, today i went to walmart, no luck. So the amps ive came down to for powering my 15" Fi BTL are: SunDown:SAZ-1000D which is $315, or maybe something with more if i can find one Audioque: 1200D or 2200D I dont want to buy or invest in an amp that is over $600 so if theres a better option please tell me. on a different note, what would an equalizer do for me,im trying to look into how to turn on and off the sub would a basic bass knob be the best? Also what are some good cheap alternators? links would be nice, i am pretty…

looking at replacing my two MA Audio HK802sx Amps for two hcca 2500's possibly...... http://www.hifisoundconnection.com/Shop/Co...sid/0/SFV/30046 I know this company has been taken over by directed elelctronics...and all the orion products arent what they used to be but....ive installed several of there new Cobalt series amps and speakers in customers vehicles and they all seem to perform very very well for the price.....so i was hoping someone had some insight on there new hcca 2500 model...... The amps i have now work great, but i only had one amp at first......then i upgraded from 8 memphis 12's to 4 Fi SSD 15's w/ bp power option and copper coils Dual 1 ohm and added …

Can anyone tell me a good less expensive 4 channel amp i could buy for my coaxil kicker ds 6.5's? i am looking at a kicker zx. 200.2 now i relize thats a 2 channel but im tryin to keep in my budget.

Hello, I have problem with choosing speakers (I'm just new in car audio), but I got 2 power amplifiers - CONCORD CA 2075 (300W),they are both 2 channel. One of them is bridged and connected to bass tube (raveland 400W). Second one will be connected to 4 speakers (2 x front 165mm, 2 x rear 130mm) , and I need to buy them, but I don't know how to compute how much Watts those speakers should have when i will connect them to this 300W power amplifier, which would have 2 speakers connected to + and - "left" and next 2 speakers for + and - "right". (You don't need to give me models of speakers cause idk if they will be available in my country, just give me how much watts they s…

Taxes are just around the corner an I have an issue to solve.my current setup 2 icon d2's an bc2000 is sitting at .5 ohms.head was up my ass when ordering the subs.My question is do I get another bc2000 not strapped or get another amp with 2500 RMS at 2 ohms or close to it?

So while doing research on the 800/880's I came across the 9800bt. Now from what I can tell they are pretty close in head units with the main differences being. 9800 - color display, bt 800/880 - active capable, left and right equalization, im sure some more tuning options im forgetting. Are there any more major differences in these 3 units? I do know they both have burr brown 24 bit converters and 5 volt outs and lots of tuning options. Now at the moment I'm not going to be running active. Eventually I want to learn how to properly go active and all the tuning that goes into making a good sounding system. Any opinions? Are there any more major differences in these 3 uni…

Ok, I'm going to make this short.... Who in their right mind would design an amplifier capable of producing upwards of 1000 watts of output, but supplies the cheesiest little friggin power connectors to run it?! I just spent hours trying to figure out how to connect 4 gauge wire to a set of crappy little power connectors that could only accept 10 gauge at most. I finally ended up using a piece of airplane cable and cable sleeve to "step the wire down" to an appropriate diameter. I was to two different "car audio shops" here in the city and explained my dilemma. All I got was a sorry, can't help you. What do you guys do when faced with this situation?

Alpine Vpower M-650 I have seen this amp at bestbuy and on crutchfield for $250+ It is only 650 watts supposedly and not 1ohm stable So i am wondering is it over priced? am i missing something here? a hifonics amp is half that price and double the boom I am asking because my friend has one and we're trying to find a good 12" to put it on http://www.crutchfield.com/S-S36Z13yjYlN/p_500MRPM650/Alpine-MRP-M650.html

Alright guys so this is my first "big" system. I have 2 soundqubed hdc3 15 d2's in a 10 ish cu ft box tuned to 32 hz. I have 2 soundqubed q1-2200 amps. I plan on strapping them. My mids and highs I got on lock so they're not important. I have a 180 amp ho alt by singer alternators. This is the absolute biggest he could make it. 1 xs d5100r under the hood and 2 xs xp3000's in the back. Nothing is installed yet I'm waiting for all my install accessories. Do you think I have enough batteries and is my alternator sufficient enough to handle 500 amps of max current? I'm waiting on my xs charger to come in to install everything because I need to fully charge my batteries. Also…

Alright guys. I picked up a Hifonics BXX2000.1D for my Fi BLv3 18. A good friend of mine has a scope, so we dialed in gains on a 0db 50hz test tone. I have the electrical to feed it. I’m able to maintain voltage at full tilt. I was reading about power and impedance rise and decided to clamp the amp and get some readings for myself. I’ll save you the time in telling me “it’s a hifonics amp, you get what you pay for... etc” I’m fully aware. I plan on going Sundown this spring with tax money. However, I’ve ran a few HF amps in the past and have been satisfied. I ran test tones at full tilt, 20hz to 55hz, measured AC voltage at speaker output termin…

im upgrading my sub to an xcon probably 12..maybe 15 (id like to get atleast some hair movement for an extra $10 why not) gunna be running it of a rockford fostgate 1500w amp: http://www.sonicelectronix.com/item_26139_Rockford-Fosgate-T1500-1bdCP-2010-Model.html a few people said that their birth sheet said 1900W battery to amp is 4G wire im driving a 98 honda crv so its a small suv question is... for running that amount of power do i: need to do the big 3? need to upgrade the stock battery (51R there pritty small) OR add another one? What would be the ideal set up to make sure everything is working full potential? and do i NEED to do it? Reason im asking is im probably…

The xtant is a 3 channel amp 75x2 + 150x1 at 4ohms or 150x2 + 300x1 at 2 ohms. The system is going in a Ford 350 dully. The doors have 6x9's. My original thought was to run ID's 2ohm 6.5 comps in the front and doing nothing in the back doors. Then running a single IDQ 10" or 12". Also thought of running 2 sets of 4ohm comps or coaxials in front and back doors. I haven't decided on a HU yet. Mainly just looking for one more geared for SQ and one that will run an ipod. I have plenty of time on this build and am not commited to anything but the xtant 603x. Any thought's would be appreciated.

I have currently a 250 amp fuse on my wire from alt to battery, would upgrading to a 300 amp fuse help or hurt in anyway? Does a bigger fuse give me more amp current to the battery (off a 180 amp alt)?

I have borrowed a tektronix TAS 475 four channel oscilloscope. It dosnt have the probes with it, i need to get them. And i want to use this to set my amplifier. So how do i make sure im testing my amp at 1 ohms? And what probes should i get? Any suggestions or tips for this would be extremly helpful. Im going to be testing a ppi bk1300.1d

okay im running my subs at 2ohms but my amp isnt 2ohm stable, its a crunch 1100wat i kno someone selling a sony 1000watt 2ohm stable amp, is it worth it? he's selling for 35 bucks, (he needs cash quick) but is it worth it?
