Amplifiers / Head Units / Processors / Electrical

Today i got my AQ2200 (used) and hooked it up to my dvc 4ohm(wired to 1ohm) type r's just to see how it works, it was dark out so i couldnt/didnt really have time to tune the amp correctly.. but i did do it by ear real quick., and i have to say.... i was REALLY dissapointed My PDX1000 performed/powered better.. i set the gains on that by ear, but acually sat there for about an hour listening to it and turning lil by lil. (not like i did with the AQ) My question is should i be afriad its defective? oh.. and do i HAVE to use the bass knob? - i dont like having one. Thank you dom.

I recently installed another amp and some 6x9's in my car along with my existing sub amplifier, I have some obnoxious engine noise going on now that wasn't there or noticable before the install. My power wire and RCA's are ran on seperate sides of the car, The amps do have a common chassis ground in the trunk. Is the engine noise because of the shared ground? If you need anyother info please let me know. Thanks for the help.

Looking around for a new head unit I've found that the majority of units from reputable companies (save alpine) dont have pause in their mid level units. Kenwood, Pioneer, Eclipse...none of them have pause in the $2-$300 range. My CD3434 doesnt have pause. Even sony units lack pause. Pioneer and Kenwood's lower units have pause and all of their highest units have pause...but in between it seems to be the companies think we dont like to pause our music or compeat... /rant

what is your favorite amplifer of all time and why? Mine is a Phoenix Gold M100 i had when I was 16---it was my first amp I ever bought with my own money. close 2nd is my Phoenix Gold MS1000---my wife let me buy(it was kinda like my birthday present 6months early) I still have both of these amps.

Ok, I have been searching and reading yesterday and today. I went back as far as 2007 but I couldn't find any topics like this one that had any good answers. My car will have a Iraggi 180A alternator (biggest that fits my car), BIG 3 with 1/0, 1/0 run for positive and negative from the front to the back and I will be using one Hifonics XX Colossus II and one SS REF4.920, giving a output of about 3800W rms. This will be a daily system, but I will be going to DB drags and other social car stereo events so the car will be competing a little bit and demonstrating the car stereo with the engine off, probably charging with a Ctek 25A charger or using a other power supply. I kn…

i just hooked my system up, and every now and then, when i have it turned up, both my amps shut down, like the remote was coming undone at the deck. deck stays on and all, amps dont give me protect lights they just turn off for a few seconds and come back on (not always off for the same length of time) my electrical system is all stock, i believe its only a 105 amp alternator, 4 gauge wire back to the distributor, and 8 gauge to the amps. any ideas?

What size fuse should be between the battery and amp?

Does anyone have any info on the new Kole Audio TRAX1-7000D pics , tested RMs rating anything would help

has anybody had any use with the Concept Audio CC-D1200 amp? It says 1200@1ohm is this a true rating? i used to own a viper vr1000d would the concept put out more then the viper?

How does everyone like their sundown amps? I've always heard good things but would rather ask here where I'm sure many have them right now.

I just noticed that Treo is selling amps these days, looks they picked them up damn near a year ago too. Has anyone used or seen these at all, it looks like a nice amp and I'm sure it peforms equally as well. Does anyone know if they're using someone elses boards in them? I bet they only cost 2 arms and half a leg.

Hello i recently purchased 2 of the power acoustics 55001d amps to power 4 SSAicon 15's. turns out the amps are complete garbage and i wish i never got them. anyways i'm sending one back to either get store credit or sell both on craigslist to purchase one of the 2 models of hifonics ( heard they are better then they used to be) and for the price i cant beat it. 1 amps per 2 subs. so my question is the subs are approx 1000w rms and the BXi 2010d should be baseline for the subs. but is it worth the extra $120 per amp worth it for the extra 600w (BXi 2610d)? also if anybody has firsthand experiance with these amps your feedback is greatful.

ok so i have a 2007 chevy impala with a 270 amp alt a yellow top up front 2 hc2400 kinetiks in the back as well as a hc3800 kinetik in the back as far as batteries so you all know all i am running is a powerbass 3000xa to my powerbass 3xl 12s 2 of them and a phoenix gold ti 500.4 old school amp to my mids and when i turn it up my headlights dim and i dont know why any help would be nice guys thanks.

hey guys im in the market for xover, whats everyones opinion on this $150 epicenter? i remember in my old system i had one i just cant remember if it was this model..but i loved it..

Hey i have a xcon 10 in my trailblazer and i am looking to put more power to it. I am currently running a cadence a7hc but the sub can handle a lot more power and i would like to be louder. I have it in a 1.1 box at 35 hz. I guess i need 1800-2000+ watts and would like to keep it under 400. Any ideas on a good amp?

Hello! This is my first post here. Crossing my fingers that I'm not breaking any forum rules. I have a 12 inch GCON ordered and the wait is killing me already. I've already purchased an amp and box for this sub and I'd like to have any willing opinions on my choices. The amp: http://www.sonicelectronix.com/item_43132_Hifonics-GLX1800.1D.html The enclosure: http://www.sonicelectronix.com/item_19279_Belva-Sub-Box-1SV12B-Belva.html A few questions: How did I do? Will this pound like crazy? How much impact will my smaller than suggest enclosure have on the sound? Ported good?How should I wire this beast-sub to this amp? (I'm thinking just running it at 650w @ 4ohms t…

I finally installed the stetsom 7KD (1 ohm 12 volt) and it ran very well but just yesterday it began going into protect.It throws a protect with one blink and the manual tells me that its a short circuit or below impedance.I'm running the amp at a half ohm nominal. It starts doing this when i roll into heavy bass. I triple checked all of my connections and everything is solid, voltage is in mid 13's when it cuts off.

If i get a head unit with 3 RCA outputs, front, rear, and subwoofer. can i use a 4 channel amp to power 2 front speakers, and the bridge the other 2 channels to power one subwoofer? this amp : http://www.sonicelectronix.com/item_44492_Hifonics-Zeus-ZRX1000.4.html and these speakers : http://www.sonicelectronix.com/item_34364_Alpine-SPR-60C.html the amp says says: 4-Channel Class A/B Zeus Series Car Amplifier Max Power Rating: 4 ohms: 125 watts x 4 chan. 2 ohms: 250 watts x 4 chan. Bridged, 4 ohm: 500 watts x 2 chan. the speakers say: RMS Power Handling 110 watts (each speaker) Sensitivit…

Is changing passive crossover same as changing headunit EQ? like i have a 9 band parametric EQ on my alpine 164-bt. and i have alpine spr 60c component speakers. the highs are very harsh. and im debating attempting to mess with my doors to edit the crossover. i have absolutely no clue what im doing with it. and dont want to risk much. i cannot find any videos for the year my car is. i have 2013 hyundai elantra coupe. only video i saw was for a 2005 elantra, 4 door. mine is a 2 door also and many years later. and about the passive crossover. i cant find any pictures only or guides on how to change and edit the crossover? what exactly is an EQ changing…

What is the reasoning for not putting one on? It should not be that hard or cost effective since many line drivers and whatnot have clipping indicators.

i could possibly sell my jbl and buy a tsunami.. what do you think is it worth, 300 more watts, thats per sub so it's really 600watts.. watcha think.. just tryin to get the threads movin

I am looking to but 1 18" BTL Fi subwoofer. I can build the box (i hope) and can do a proper job installing it. I have a sufficient enough amp sending 3500 watts continuous power its way. I have 0ga power wire ran 10ga speaker wire. But i have the stock alternator and battery. Is this a problem? would a nice cap handle the difference? Or what should i get to solve the problem?

Well I have finally gotten around to using the MB Quart PXD-213, I have had them sealed in box brand new for 6 years now. Fantastic product just never used them. The question I am having is this and it may sound like a noob issue so please be gentle. I have a phenix gold 250.2 running them, have 12 gauge speaker wire in lengths less than 3 feet from amp to crossover, now I don't understand the installation diagram cause the damn thing is in german. or deutsh. so here is the issue, it says to run biwire from the amp into the low input and the high input, I have them wired just to the high input from amp and they sound phenomenal. now the issue is this at high volum…

ok well i dont know if this is exactly where im supposed to put this topic, so correct me if i'm wrong. I'm looking to start making some stuff for my dorm room next year, and i was wondering, what some good brands of amplifiers that are out today in the home audio spectrum. i mean power amplifiers, for subs and such, and also some other good 4-8 channel amplifiers for speakers. I assume i can just use a home theater receiver for the speakers and such, but as for the power amplifiers, im lost thus far. What are some brands that you all like, that y'all recommend. ive been looking at some Crown, but i dont know. My dad has meridian, but thats out of my price range for s…
