What are some brands of some good solid amplifiers that do over rated power? I know majority of fosgate power series amps are underrated by at least 1k watts

I'm new here so bare with me. I have 2 power acoustic mofo 124x 12 inch 4 ohm dual voicecoils subwoofers running at 1500 watts rms each (3000 watts rms together). They are both wired parrel for 2 ohms each and wired to together at the amp for 1 ohm. I have a skar audio RP-4500.1d mono block amplifier pushing these subs. My question is do I need to upgrade my charging system to 2 high output alternators and 2 batteries along with the big 3? I did the math with the ohms law and just for my audio system alone I need 450 amps. I figured two 300 amp output alternators should be plenty. Am I right or is this overkill? If I'm wrong help me and gave me some advice on what I shoul…

What are some of alpines flip out monitors that work with the h701? i was looking at getting a iva - d310. Any experience with this headunit? Also would i be able to hook this up to a pioneer 9800 headunit? Without a dvd display is manually tuning this a pain?

Okay so im asking this question for a friend of mine. He just recently bought a hu from a local shop and they do free instal with the purchase...well they said that his car has a factory amp and that they will have to by pass it by running all new wires which will cost $120. I am still learning but this just doesnt seem right. I mean why would you want to bypass a amplifier? The shop said that running the amp would equal less output to the speakers but bypassing it would make it louder. I just dont quite understand the logic so if someone could explain it would be great. thanks

Is there a way to run a h/o alt for just the stereo and its batteries AND keep the stock for truck functions only? Looking at 200 amp alt for the system and it seems no one has any idea if this will work. I can make the bracket and pully, I've got a lathe and CNC here so no problem there, but I would like to solve this issue and how much I have to chit out to make it work. Should I just bolt up a couple of big junkyard GM's and call it a day? Any ideas??

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.

I have 2 Audioque 2200d amps..My question is what type of electrical would i need? My car has a 160 amp alt,and i have 2 deka g31,would that be good for it? Its gonna be for daily usage..Thanks for any help.

i was just wondering if any of you have had any experience with this amp? i can get a KILLER deal on one in mint condition and wanted to know your thoughts and opinions of it. thanks

I had a sundown saz 2500d shipped to be and I'm positive it was dropped during shipping and the speaker wire input busted off. I was wondering how i could go about getting that fixed and what the cost would be. or if I can just order a new one. The metal that connects internally is busted off. I'm not positive if its covered under warranty or not. I emailed sundown and haven't heard anything back from the yet. Any help would be greatly appreciated.

Like the title suggests, would it be practical to build a tube amplifier from scratch for a subwoofer? i need between 20-40w power @ 25hz 20w is acceptable but the more the better. Looks and size don't matter. Budget is $150

Are these any good? the amp I'm getting, an AQ2200d requires a 200 amp fuse, and im using 2/0 welding cable so i figure il ljust get five, best bang for my buck and in case any pop i'll have an extra http://cgi.ebay.com/Tsunami-200-Amp-ANL-Fu...bayphotohosting And for a fuse block/holder, should I use the typical screw down the cable, or should I get the ones that you use a wire terminal on each end and just touch the fuse together? Have any suggestions on some? I need 2 affordable ones, but 3 if they are REALLY affordable.. I'm not trying to cheap out, but I just don't think its necessary to spend 75$ on three fuses... (since I'm using 2/0 thats why I'm wondering becaus…

so im gonna be pushing 2 fi bl 15's with flatwound coils and the cooling option. so... 2x hifonics brz1700's http://www.sonicelectronix.com/item_23547_Hifonics-Brutus-BRZ1700.1D.html or a hifonics colossus http://www.sonicelectronix.com/item_32990_Hifonics-Colossus.html ive got strong electrical so feeding power to the amps wont be a prob thanks everyone!

So can u guys tell me which head units u think are better sound quality wise and features. I'm goin to get either a pioneer premier or kenwood excelon and idk whch one to get. My friends tell me kenwood isn't any good but I hear from experienced car audio technicians that kenwood makes better head units than premier. I was looking to get the Kenwood Excelon KDC-X693 or the Pioneer Premier DEH-P510UB. They are both around the same price and all advice is greatly appreciated. Thanks, Nick

Just threw in some more but not done yet!

Okay about 6 months ago i hit the power cable on my amp and it fried the amp... i had to turn the gain way up to get the same output voltage. Anyways i didnt think much of it but i just spent 610 on a new sub and amp and do not want to mess anything up. Last week i checked the preout voltage and it was at 2.3v... its suppose to be 4. (deh-p590ib) Should i replace it. Do you think theres anyway it will cause amp clipping or distortion to ruin my speakers/amps/subs. I have used my system atleast 30 min a day for the past 6 months like this without any damage and there is no noticeable distortion, but i really dont want any of my new stuff to **** up a year from now thanks

when tuning an amp without the bass boost on you tune it right before the amp starts to clip ... so if you increase the bass boost wont it make the amp clip or am i missing something?

I recently had an apline head unit installed in a toyota camry. I have a memphis audio amplifier pushing four 6X9's and an JBL amplifier pushing two subwoofers. Everything was working fine in my jeep and then yesterday when it was installed in my camry this happened. The head unit puts out an audio signal to the amplifiers only when using the radio, the cd player and ipod can't be heard through the speakers connected to external amplifiers ( but the cd and ipod can be heard through the speakers that are being pushed through the head unit's internal amplifier).

SparkFun Electronics - DSO Nano - Pocket-Sized Digital Oscilloscope seems pretty decent, not sure if it covers the ranges needed to detect clipping from HU and also to set my gains properly...Any input? Thanks.

hey guys i just orderd a SSA xcon 15 and i am wondering if there are any other amps beside sundown that is worth buying because i do not have the money for a sundown amp. i was looking at hifonics and they have 1500 RMS amps at 1ohm for 200$ are they any good or can you guys give me any ideas on what other amps that are good for less money. please let me know. Thanks

i just put in my sundown 1500D and it turns on, but nothing comes out of it volts or anything

Ok, im looking for a head unit that is vibration resistant, clean output, good looking (matching my interior, ill post pics if i am asked), plays MP3's and WMA's preferably (so i can keep one CD in for 3-4Hr drives), and i would like an RCA in too but that isnt required. I only need 2 sets of RCA's. I would like pause as well (if i ever want to compeate bass race it would be nice) Im getting a $139 refund from Ikes Sound for the DEI1100D (its good because i paid $70 for the amp, send 29 to get it repaired. Im basically making $40) and soon ill have around $100 from my parents, maybe more if i score awsome on the ACT (lol). so my budget is around $240 and the above is what…

posted this else where but, looking for as much in put as possible Well ladies, its time to add some more batteries. I'm plan on going from 1 AT3000.1, to two Current electrical is a 230 amp alt, stinger SPP1200 under the hood, and an HC2000 in the trunk with 4 runs of 0ga Full tilt daily I might see 14v flat as long as I keep it revved lol. Lowest I saw it drop while metering, was 13.5 but I let of the gas... But it seemed to stay at 13.8 or higher after a long burp staying revved. So I have options for batteries mainly, just adding a second to the rear. I'm considering a D3100 since its about the biggest I can get (max cubic inches is 800 per batt in usaci) and is extr…

Did you know that of all places Circuit City is now stocking Eclpise?? I have just gotten and installed the CD-3000 and I do have to say it is VERY nice for the money. Not a ton of features that you dont need but it seems to have good clean sound. Nice 5v constant outputs from the pre-amp. A few built in EQ's and a somewhat OK cross-over. It playes MP3's ect and has a pretty nice display! I would love to see the CD-7000 in action. Then again.. I dont need navagation! Good day all!

i plan on running 2 12" fi q or ssa icon subs in a 4cf ported enclosure tuned to 28hz. my car is running a minibattery upfront (to clear upper intercooler pipes), an optima yellowtop (extended battery, not standard), 2 1 farad caps, big 3 upgrade, and a 180amp iraggi alternator. the amp im currently using is a mtx 1501d (1500watts @ 1 ohm). here are my concerns: 1) would it be worth it to upgrade to an amp that is around 2500watts? 2) how many watts can my current electrical system handle? 3) will i be able to run an amp around 2500watts and another one for mids and highs around 200-300watts? 4) what amp would you guys recommend (looking to spend $800 or less)? so far…

Been gone for a while....need some insight. I'm ditching my Alpine 7894 for something newer and with more tweaking ability. I've been looking at the following: Eclipse 8445 Eclipse 8443 Eclipse 8455 Eclipse CD5000 Pioneer 960mp Pioneer 9600mp Can anyone share their experiences with these units or whether or not one has been consistantly praised more than the rest. Any flaws, things you wish it had? -It needs a 3way xover or better (wish there was a decently priced 4way xover) -At least a 7 band parametric EQ The Burr Brown 9600mp makes me want it more than the rest. Are there any reasons to not weight this over the rest? Can anyone tell a difference? I'm also replacing …
