when someone says there amp is 80% efficient at 2600 watts what exactly does that mean electrical system wise?

hey guys if you could get one of these 2 amps for the same price which would you go with? kicker zx 2500.1 2500 watts birth sheet around 2700 watts us amps md.3d 2000 watts again same price

a buddy of mine told me to add the 2 i never used none of them he said that they will help my 15's hit harder

Amp is from 2001-02. There was a mod for it put out more power. I can't find it anywhere. Thanks

Are the zapco SP7-SL and arc audio PEQ 1/2 din mountable, as in can I mount them under my denon HU in my 1 1/2 din dash? If so, how would I go bout doing this? Just take out the pocket and slide in the eq?

I am currently running a set of Crystal 6.5" componants on my Sundown 100.4 The HU Is a Pioneer DEH-P6000UB I keep having some "popping" from the mids.........as if they are almost over excurting at times. HU High Pass is set at 125 Hz The amp is set at Full Range. I cannot seem to find a way to shut off the High Pass on the HU and i wonder if turning on the High Pass on the amp could cause some issues. Also what could be the other causes of this besides it being too low a crossover point? Gain is slightly less than 3/4 no bass boost or anything else. Ideas are VERY welsome. J

Ok, i've never ran multiple and have come to a barricade here so fill me in. 1 battery up front, 5 batteries in the rear. 400A for bass, 90A for mids\highs. Total Amperage fuses needed- 490A ~ 500A. Ok, first off- I'll have 3-4 runs of 3/0 wire going from front battery to rear battery bank. Right now, i just have 1 3/0 wire ran which is fused with ANL fuse and no fuse at other end because everything is dismantled right now. With 3 runs, i was going to attempt to use a bat terminal that had 3 1/0 connectors on it. I run the alternator to one of those leaving 2 left. The factory electrical wiring goes into the other slot leaving one left. I'm assuming i'll use a distro blo…

I recently swapped out my Pioneer DEH-P5900iB for an Alpine IDA-X001. I absolutely love the usability of the unit, but it lacks the equalizer features of the Pioneer. I'm considering getting either an AudioControl EQL or MA MA15EQX for my front stage. It would be mounted on my sub box, not a dash model. Any recommendations? Thanks, -fp

I just installed my new HU, it's a Pioneer DEH-P690UB (not the best in the world, but it gets the job done). It has a usb connection to hook up your iPod and other usb mass storage devices. My question is what brand/make of HDD works? I've already tried a few and they are a no go. Reason is I think they are requiring more juice then the usb cable can provide. So if anyone can point me in the right direction and stop me from wasting more time and money trying out different usb hard drives I'd really appreciate it.

I was trying to decide on an amp. I was looking at the Lanzar Opti 6000D. Can anybody let me know if they have had an experience or know about it. I will be using it for 8 15's in a ported enclosure from 16-20 cubes tuned at 25 to 28hz. I also plan on using lanzar's line driver.

I can get my hands on a Kar 1000.2t and I just wondered if there were any good, mostly from a SQ perspective but for a daily driver not that fancy. Anyone know if this is a class AB...what apps it would work good for? http://www.realmofexcursion.com/ampguts/Arc_KAR_1000.2T/ I guess a cerwin vega and clarion are the same amp.

is this amp any good? ive heard its pretty good.

I have a 86 150 with a 5.0 in it. It came stock with a 60 amp alternator. My neighbor gave me box full of stuff he took off of a 94 mustang 5.0 H.O. One of the parts happend to be a stock 130 amp alternator. Since i need to get a bigger alternator anyways and strapped for cash i figured i can use this alternator. Its a direct bolt in, but the plugs are different though. My stock one has 2 plugs instead of the one plug. But one of the plugs on my wiring harness is the same style plug on the new(er) one. So wat i did is that i plugged(sp) in the plug that looked the same and hooked up a 4 guage power wire directly to my battery. Installed it and cranked it over, i…

i was looking at epicenters and crossovers and i ran across this model which i think may be what im looking for..it give me the capabilities of a crossover and it also gives me the bass control knob where i can raise and lower the bass from the drivers seat which is what i was wanting from the epicenter..what do you guys think? http://www.woofersetc.com/index.cfm?fuseac...Product_ID=1254

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..

I'm in need of either a 2 or 4 channel amp to drive my 6x8s and 8" midbass speakers. I'm only used to mono sub amps so this question may seem silly. My concern is I want to set a High and low crossover for the midbass. A range like 80 to 250hz while the 6x8's play 250hz and up. A) Do 4 channel amps allow you to set a high and low x-over at the same time? B) Can I just use a 2 Channel amp and buy passive crossovers that will send 80-250hz to the midbass and 250hz and up to the 6x8s?

have you guys had any experience with these? you kno the ones with the lil 3.5" screen. ive been thinkin bout buyin one so was wondering to get some feeback on them. thanks

I got a buddy that just bought a JVC KD-DV7300 H/U. This model does not come with a built in monitor. He is wanting to connect the unit so that the DVD monitor is capable of running all the time. He has a 13" external screen that he has previously used. The unit has a light green wire that is supposed to be connected to the brake line. Is there a way to over ride this? Thanks.

I drive a 2001 GMC Jimmy 4 door with a 4.3L Vortec V6 and want a 200 amp or so alternator to replace my stock one with and would like recommendations on what companies to look at. I am considering Excessive Amperage, Mean Green, PowerMaster and KnuKonceptz. There were others but I forgot them. Any feedback is appreciated.

See the smoked plexi in the middle? What does everyone think? Leave it? Replace it with a clear red? Replace it with clear and have JBL and Crown etched on either side and backlit red?

i recently got a crossfire CFQ5.2 equalizer, but it didnt come with a munual or anything to tell you how to hook it up. can some one help me?

I currently have a Pioneer 9800BT headunit with the ipod interface. I want to run active and unfortunately this headunit is not capable of meeting my needs. I want a headunit that is very SQ and processing oriented. I was looking at the Pioneer 880prs hoping that it could be a direct drop in. What is the difference between the 800 and the 880prs? Also is the new eclipse CD7200MKII far superior then the 880prs? and how does the alpine 9887 stack up in this lineup. This headunit will run to a sundown 100.4 amp which amps Peerless HDS tweets and the sea excel 18nx mids. Any suggestions and opinions would be appreciated.

Well today at the TBP bass wars event, I found out that I'm not getting any voltage readout off the RCA's from the headunit. Tried it with several meters and it wont register anything, just shows 0.00 .....So apparently, I'm not getting any RCA voltage input to the amplifiers... Someone suggested I needed a line driver to solve this problem. My question being, would this solve the probem....being that I can get a cleaner signal and can adjust it to the voltage I want.. ? Thanks for any help guys, it is very much appreciated........I'm still learning, so please bear with me...

Okay I just put it in my new 5000 and I have two amps... Sundown SAE-1000D and SAX-100.4. Well I have two sets of RCA cables going to the 100.4, one set going from the front preouts on the 5000 to channels 1 and 2, and the other set is going from the rear preouts on the 5000 to channels 3 and 4. For some reason I'm not getting any music out of the rears. I can hear a very faint "tv snow-screen" type of sound coming out when I have my ear up to one of the speakers, but that's it. Anyone know what's going on?

Looking to purchase a good amp kit to power my SAZ 1500d. I was looking at the Kolossus 1/0 Amplifier Installation Kit on Knukonceptz.com, but I'm open to suggestions/brands. Thanks for the help.
