So my midbass amp shuts off after 15-20 minutes of hard playing. I am pretty sure I am asking the amp to do more than it is capable of, BUT also know my mounting location is NOT ideal. SO heres the details. The amp is a Alpine MRP-F600, capable of 300 watts RMS x 2 @ 4 ohms. I have the amp mounted on the back of the box, with the vents running side to side, in a SEALED trunk. The midbass drivers are Aura NS10-513-4A, Aurasound NS10-513-4A 10" Subwoofer NLA from Madisound The Auras are rated @ 200 watt RMS and 800 peak. I have the Aura's crossed @ HPF 50hz 12db slope, LPF 400hz 12db slope. The Aura' are mounted IB in the front doors. There is TWO other amplifiers in th…

Hy, I want to upgrade my midbass amplifier (focal 165k2p) and I don`t know wich one is better for my set up (alpine 9835, focal k2p mid, hybrid L1 Pro tw). The Hybrids are moved by a small Zapco Z50S2. So: 1.JL 300/4V2 ~200+$ 2.Zapco Z150S2 My link My link2 ~150$ 3.Zapco 350 Driving Force: Stereo, 4 ohms: 2x100 Watts Stereo, 2 ohms: 2x175 Watts Bridged, 4 ohms: 1x350 Watts T.H.D. + Noise: <0.015% S/N Ratio: >95dB Slew Rate: >29V/uS Optically isolated MOSFET power supply Surface mount technology w/1% resistors, precision caps, and massive ground planes ~ 320$

I have read all over and i cannot find anything on how to tune a vocal amp. I'm buying a Sundown 125.2 from a friend of mine and hooking it up to my stock door speakers. i eventually will upgrade but for now i think my stock speakers will sound cleaner then off my h/u. and another question what ohm are stock speakers usually? or do i need to find that in my manual?

Does anyone have any experience with the AQX3500's? im planning on running one on 2 AQ HDC318's copper coils. Id like to run it at .5 ohms, will it become a frying pan or will it be ok.

ive got two amps in mind does any one have thoughts on witch would i be happier with the saz2000d or the aq2200d the one that i get will run one 12" fi btl w/cooling in a 2.5ft3 tuned to 33hz big three and 200amp alternator just wondering witch to go with

I have 2 questions, and was hoping for some answers. 1. Do they make custom alternators, or just the ones listed on the site? 2. How do I contact them? (Is there an email, or do I just have to do it through their website?) Thanks guys

Me personally do not like threads like the one i am making currently.. but i just need suggestions for my brother. He's getting (2) 15" BTLs for a 99 Dodge Dakota RT. I need amp suggestions, either.. (2) 2k amps that can be strapped OR (1) 4k amp The amps can be around 2k or 4k. We've thought about AQ2200 and SAZ-4500D Thanks, BanginGMC.

I'm looking at getting an 18" btl to put in my jeep, i have box plans, but i am also looking for an amplifier. Has anybody ever heard anything on Planet Audio, or do you have an idea of what better amp I should get to push just one 18? EDIT: I'm looking at the Planet Audio AC4000.1D Amplifier

I read through the tutorial but I'm still confused. I have this DMM: Amazon.com: GE 50953 Multimeter, Digital 17 Range 6-Function Which setting do I use? I've been searching for about a week, but can't find a clear answer.

how much resistance is too much on a grounding point? Ive already read that under 1ohm is optimal but after doing some checks i'm just not going to get that in the rear in comparison to the front. my lowest reading in the back was between 1.8-2.1 Is that good enough? My next question is on the power wire. I'm using the rear battery as a distro for my amps. measuring from front to rear then from amp to the the end of the wire is normal. but when i connect all to the battery the rear battery and measure I'm getting 30+ ohms on all connections in the rear even on the wire that is coming from the front battery. also this occurs on both ground and power wires. the battery is …

wonder if I should install my phoenix gold bass cube? we have to play a song supplied from the judges for spl and sq categories. You guys think it would make a difference?

CAP50 - Alumapro 50 Farad Capacitor/Distribution Center Whats your oppinions on these? This guy I work with used to be a car audio installer, and we were talking today and he was swearing by this saying that is was better than a regular capacitor, better than a battery. He was saying it keeps your voltage at 14.4 no matter what. I was just wondering if anyone here has used them or has any first hand experience them offer up your oppinions. No I don't believe in capacitors Im not a cap fanatic or anything but he swore up and down it was different so I just figured it'd be worth it to get you guys oppinions.

Hi guys, I've been driving a lot more now and I was looking to get some better sounds since my current set up is factory. I'm hoping to spend around $600 NZD (~$400 USD) on it all.

hey so i was digging through my basement the other day and i came across the amp i used for the sub in my very first car it was an audiobahn A2300E i had forgotten all about this thing, i tested it yesterday with my recently retired infinity reference 12 and it sounded pretty good i can't find any information on it anywhere, the only thing i have found is someone saying that "they believe it is 210 rms bridged at 4 ohms" this seems pretty possible since it only has 1 30 amp fuse i would of course be running 4 ohms per channel on 100w rms speakers, so this seems perfect for me, i know audiobahn isn't great, but i already own it so i might as well make use of it. what ar…

I'm wondering will a active head unit solve my problem. I have a jbl gto 1201.1 II and it doesnt have a subsonic filter. I probably going to get a Alpine 9887.

I currently have a CDA-9855, but the CD player is starting to skip rather easily. I want to know what would be some good HUs. I'd like it to have HPFs and a LPF with adjustable slopes,2 way and 3 way xovers, graphic eq and/or parametric eq, time correction, full speed ipod/iphone capability. I think the 9887 is nice but does anyone have experience with them as well as "imprint"? Thanks

Ive got a few questions for those of you that have this amp or have owned it at one time.. i remember reading somewhere the 3000 was only stable down to 2 ohms, but im seeing it on ebay advertised as 1 ohm stable.. true or false? also the power and ground inputs on the amp... 0 gauge or 4 ga like the 1500? thinkin about picking this amp up .. maybe.. thanks.

Is the DMM method a fairly accurate way to measure the watts output of an amplifier? I set the meter on AC volts, connect leads to speaker terminals (w/ subwoofer still hooked up), play a sinewave burp and take that reading to determine how many watts went to the sub. Does that sound correct? I already set the gains w/ an o-scope so I'm not trying to do that. I want to calculate how many watts actually is going to my sub thanks

I have been reading around on some build logs and people are saying that they have an amplifier that is "clamped". What does this mean? I have been googling around with no luck (so far).

One of these will be my next amp. The T1500 may or may not be the CP version. I will decide that if I decide to go with the RF amp. Will be powering two DC lvl3 15's.

I'm going to get a fi bl 12 with a SAZ-1000D amp and i was wondering if i needed anther battery or alternator or anything like that. my car is a 1997 honda accord lx and everything is stock.

so ive done the big 3 upgrade with 0 gauge wire. have a solid ground from amplifier to frame. yet my amplifier is getting hot and shuts off. input sensitivity is st to 85% db gain is at 0 subsonic bass set to middle frequency level is set to middle what could be causing the over heating?? LOW VOLTAGE??

i have a 130 amp alt and a ever start battery up front i'm buying a audiopipe 15001d i was wondering if that would be sufficient for that amp if not i was thinking of a shuriken bt60 60ah and 1500 amps i want as minimal voltage drop as possible

I don't want to use any of the wiring that comes from my truck. How would I run new wire and what wires would I have to include? I don't need speaker wires because my amp powers my speakers Head Unit is http://www.kenwoodusa.com/Car_Entertainment/In-Dash_CD_n_DVD_Receivers/1-DIN_CD_Receiver/KDC-MP342U Truck in sig.
