im looking on getting an audiopipe amp because money is tight for me right now. but i want to know what the difference is between the ap and aqx series. both do rated?

http://hypnoticusa.com/vertigo_amplifiers.htm When they say "rated power" I assume that means RMS and not Max, correct?

hey everyone! i just finished building my first box today for my ssa icon and couldnt be happier. i bought the sub and amp used and i believe that the settings on the amp are off a bit. the sub hits the lows great (i tuned the box fairly low) but when it comes to even remotely high notes that should rattle my teeth out there is almost nothing there! and example is white girl but usda...it hits that low note like a champ but when it comes to the high one the door speakers are louder than the sub. i did some research and am thinking it has something to do with the low pass frequency and high pass frequency? also i have the gain turned all the way up...that was the only …

Can it be done folks?

Pioneer GM-D8604 http://www.sonicelectronix.com/item_63974_Pioneer-GM-D8604.html its $140. class d RMS Power @ 4 ohms 100 watts x 4 channels its around $100 cheaper than the next comparable amplifier that has RMS listed and is a decent name brand? Im aware that its class D so, thats part of why its cheaper. But other than that, im worried its bad for some reason because of how cheap it is?

I been trying to do some research on some 7-7.5 rms amps but not really making a ton of progress. What are some good amps that's within this power range with the exception of dc. i know b2 m1s and ns1 v2 are in the category but what are some others than im overlooking? i need two budget is $3k

Just got one but how small are they really? It's 11-3/4 inches by 6-1/2 inches? Seems kinda small... Also, anyone have photos of their own collection?

ive got a Diablo Audio Hellfire 8000.1 it has a blown power supply. where can i get it repaired? Db-r does not do them, already checked. i know of amp medics, any others? and what happened to them? their website is gone, and i cant find them anywhere.

I've been doin some research about this so if i make a mistake, let me know. I got a chart from the12volt that lets me know what inductors and capacitors to use for a desired slope and roll off and diagrams for slope configurations. I also know what VDC one should shoot for based upon power used. Now, i would like to start studying the parts themselves. I'm starting with capacitors first. From what i'm reading, for high quality, low distortion use, to use caps that start with poly-... preferably polystyrene film caps. I would like to purchase all my parts from partsexpress.com and these are the ones they offer- Audiocap Theta Polypropylene Film Auricap Metallized Film Day…

Would anyone on the forum have suggestions regarding fair market value for the following US Amps USA 2000x? I recently purchased a new set of Definitive home audio speakers and am looking to possibly trade rid my old set to a friend for the US Amps USA 2000x pictured below. I've been out of the car audio loop for quite some time and appreciate your feedback. Thanks-Chris

didn't see any reviews, so i figured I'd ask. Just curious, not buying it.(*putting on the flame suit*) http://www.sonicelectronix.com/item_45477_SPL-GLA1-6000D.html

Hey all. I'm at a loss right now. I'm preparing for a build replacing my subwoofer. I will be using around 2500 watts of bass plus 250 watts of highs. I'll have one battery, but I rarely play the system with the car off. Anyways... Nathan (from Excessive Amperage) seems like a great guy and super nice, but I'll be paying $25 more for 20A less. The Power Bastards alt is 220A and the Excessive alt is 200A. Any recommendations? Comments/experience on build quality? Both come with an overdrive pully and a one year warranty. Thanks.

The DSP aint working correctly on low input only on BT mode. On low mode only ch1/2 work rest aren’t playing, BT mode all play perfectly. I sent back to AD & was told there is nothing wrong that all outputs on low mode are working . other issue i get a clock ticking sound from ch 1 & BT keep cutting off every few seconds or minutes.

Well im almost done with my Bravox components install and I was wonderin, could I just hook those up to 2 of the channels and not use the rear. No bridging... just using the 2 channels alone. I just want to hear them before I install my rear. Thanks.

I have two dual 1 ohm 18 BTLs fully loaded in a single chamber box...12 cubic feet after subs and port...with two kicker 2500.1...my gain was all the way down...my bass boost on the amps was half way up with the bass on my head unit at zero...when ever I turn my remote bass up the amps starts clipping...I had two MTX 8500 12s that hit louder on the local meter...I have a 275 amp alternator with another one on the way with two red top optimas all zero gauge wires power and ground wires...can someone help me out...I know these amps are better then this...

hey everyone. i came accross this amp in my friends basement and he let me keep it. its an Alphasonik MA-2055. doesnt have the regular speaker terminals. has all the different colored wires. has power and ground leads coming out of the amp. on amp it says: minimum continuous average power: -55w per channel (2chan). both drive into 4 ohms...? -110w mono mode into 4 or 8 ohms. -freq resp 20-20khz -THD <0.05% does anyone have ANY info on it? couldnt find anything on google... thanks! PICS!

Wanted to see opinions on where I should set high and lowpass filters on my sundown ns1. I'm slowly figuring my issue out but open to others imput. Enclosure is 5 cubes after displacement tuned to 35. Everything on my head unit is set to flat. Any help is welcomed

Amp: 1200x1 at 2 ohms Subs: 2 DVC 4 ohms subs wired to 1 ohm I'm using a DMM to set the gains and my guestion is: Do I set the gains using the formula volts = SqRt of(1200 x 1) or volts = Sq Rt of (1200 x 2) The difference is 34.6 volts for the 1200 watts at 1 ohm and 48.9 volts for the 1200 watts at 2 ohms

Hey guys, I'm in the process of building a system for my Infiniti G35 coupe and I'm trying to figure out which amp to get. Here's what I'm getting: Front components: Focal 165 K2P's, 100W RMS Rear Midbass/Midrange: Diamond Hex S6.0mx3 150W RMS, or Infinity Kappa 62.7i's, 75W RMS (Haven't decided if I want full range or not in the back) The amps I'm looking at are: Audison VRx 4.300 4x110W, $1300 Audison VRx 2.150 for the fronts, and run the rears off the HU 2x110W, $860 Audison LRx 4.300, 4x65W, $640 Focal 4x75W $620 Audison LRx 2.250 2x110W, $525 Diamond 6700.4 4x110W, $525 Focal 2x75W $420 I would love to get the Audison VRx 4.300 and be done with it, but it takes a lar…

So I've been researching ground connections, always trying to learn more about a subject, since I was upgrading some things its always a good time to refresh my memory. I've basically come across several ways suggested to make a good ground, and there are a few that stand out to me. 1) Using dielectric grease to seal moisture out of the connection area, with the idea that when you crank down on the nut to secure a ground lug to the chassis it will push this grease out of the way so the metal connects properly together and helps seal out moisture. 2) White lithium grease. I've seen this mentioned several times, but I truly feel it may be an outdated recommendation. …

Without having to delve too deep into the world of signal reproduction and the discrepancies in what the human ear perceives, can someone please simply explain distortion, how it relates to us simple "daily system" people, and the relevance/relativity in terms of overall distortion of "-40 dB from the fundamental." I read this article, and I understand the basic concepts presented, but I was wondering if anyone could put it in more of Laymen's terms. Thanks!

ta92001. anyone messed with this amp? rated 3k @ 1 ohm, birthsheets supposedly read around 3.8k @ 14.4v true? good amps? looking to get one to be run @ 1 ohm on an 18" mt. also looking at getting the ta91002 (750w x 2 @ 1 ohm) and the ta7402 (i think thats it) discuss.

Hey does anyone know anything or have an opinion about this amp

I need a 5/6 channel amp for one of my cars. I need about 75-150 or so watts per channel on channels 1-4, and a 5th (or 5th and 6th bridged) channel to run a sub with 500-1000 watts. I was looking at the following: US Amps AX-5600 US Amps USA-5600x (getting hard to find) Hifonics Zeus ZXi60.4 + 1k Memphis Belle 16-MCH1300 The only problem with the latter two is that they are most likely made in China... which is a huge turn off for me given my recent experience with chinese made amps. Anyone have any other suggestions? Sub is unimportant at the moment, as it will be picked after the amp is. I'm trying to stay under $500, if possible, but that is not a hard cap. I alos wan…

what would you guys pay for a good working Kicker KX 800.2 thanx
