How do you measure the actual output of an amp in watts? I remember my friend Aubrey telling me how, but cant find the info again. Im trying to figure out what my 601S Rockford Fosgate Amp puts out. It says 600 rms, and 1800 peak, which is strange for the peak to be so much higher, but anyways I've also heard that RF underrates their amps substantially like Kicker does. So my question again is how do I measure the power an amp puts out?

I was wondering how this is done? I'm sure it's something simple, but I'm having a brain fart, and can't figure it out!! You know how meade and many others can control all their amps (2+) from 1 bass control knob.

I need some info on these things..I've ALWAYS added an after market head unit to all my vehicles in the past. I've always though that is the best way if you want a good system. Well, I have the chance to uby an 08 Cadillac cts. Clean as hell and would be by far the nicest vehicle I've ever owned...but I'm a bass head. So questions would be.. If a clean sounding, hard hitting system is my goal will the LOC be the wrong purchase? Maybe I have the wrong idea about these things? If an after market setup was available I wouldn't even be typing this but as far as I can tell it doesn't exist. Appreciate anything you guys can add to this, its killing me that not being able to pu…

I just recieved my new Fi BL 12 and am looking for an amp. What would be best. A used audioque 1200d, new audiopipe 1500d or a new soundstream 1200d. Sub has flatwind coil option only. Dual 2 ohm

I think I might go full active, and I would LOVE to go the route of a 6ch amp. I was looking at the Audison VRx6 Direct, damn its expensive. I know PPI had a nice PC6600.2 back in the day before the DEI switch over. SoundStream had the Davinci (overkill for me, I dont need 7channels) Anyone have any other suggestions?

how would an audiopipe ap1500.1d preform at .5 ohm. with 14.2 v roughly.

Is hifonics a good way to go for amps?

Question for yall: I just got my saz-1500d, hooked it up, all is good. With my previous amp, I use a kicker kx3 xover for the linedriver/bass knob features on it. Just for kicks, I hooked up the kicker bass knob to the sundown amp. It works fine, but when I turn the knob up over halfway, rather than increase gain, it decreases gain. It does get to the same volume level that the sundown knob gets to, I'm just wondering if it will hurt anything to use the kicker as it is already cut into my dash. Thanks for replies.

ive always messed with pioneer head units. i just sold an old pioneer flip out and ready to buy something new because my old stock is not cutting it. if i go with a regular cd player im either going with the http://www.sonicelectronix.com/item_45846_JVC-KD-HDR61.html http://www.sonicelectronix.com/item_42778_Pioneer-DEH-P8400BH.html if i decide to tackle a double din im either going with the pioneer or the jvc.im just wanting to know which would be the better head unit and which offers the best features. http://www.sonicelectronix.com/item_33384_JVC-KW-AVX640.html http://www.sonicelectronix.com/item_42781_Pioneer-AVH-P2400BT.html

Hmmm so I was just wondering... Why is everyone so dead set against a cap?

nevermind..hehe what if i can't reach the engine block ground? will that be alright? wheeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

just wondering what everyone thinks about this amp ? thanks all. does it do rated power? is it stappable? are they quaility products?

ive searched for a while with no luck. i have access to a O-scope to set it but i was wondering if ther is anything special i need to know to set it?? any info will help too.

Alright I just want to clear this up so I don't fry an amp. Here is how I will have my set up wired. What do I disconnect just the front battery negative? Or what? And do I take out all the fuses then plug in the postive to the amp and THEN negative ? I just want to make sure

Which amp for great sound quality and build, but the MOST important is efficiency (stock 90amp alt. but doing the big 3 soon) .thankz in advance. JBL GTO1201.1 II Apline MRD-M1005 INFINITY 1211A Kenwood KAC-X1R Orion HCCA-D2400 PHOENIX GOLD RSD1 SoundStream PCA1500D 200.1

What are the advantages or disadvantages of swapping air conditioiner for second alt ?

i think my alternator is dyin cause the voltage drops when im stopped...i need help on choosing a H/O alternator....how many amps also??

ok, the problem is there is a noticable humming noise comming from my t1500-1bd, and its from the amp, not speakers nor subs it is a high pitch noise, and the worst is that when i turn the bass knob, the bass is louders, but then suddenly you start hearing the pitch noice more, and distorts, thats when i need to lower the bass knobs any suggestions thanks

heey guys i have a Fibl 18un wiht cooling dual 10hm to a jbl gto1200 amp going at 1200watts rms. so orginally i set the gain by ear and had it at little less then 3/4s of the way. Then i set it using the voltmeter and play a 50hz tone with my radio volume 3/4 and i set it to 47 My math for it was 1200X2 then take square root u'd get around 49. but when i did that and played bass i love you at about little less then 3/4 it was barely flexing before it was just dancing adn it not as loud and it sounded like there was more stress on the sub. Got any advice?

So i bought a 1male to 2 female rca adapter from monster because this hu only has one output for subs...but for some reason i cant access the subwoofer controls or the dolby 4.1 settings on this thing...it appears only in ghost writting not in white...whats is wrong?

Driving my truck with the radio at an inaudible level. Subs just pop. Kinda like an amp with no soft on/off feature. Went to the back and looked at the voltage meter on my rear fuseblock by the 2nd batt. Reads 10.38v. And my subs have engine noise now. What happened? Its a 1991 ramcharger. 318, 220 A alt. And a red and yellow top.

Hey there guys i just had a quick question. Right now in my car i have a ssa zcon 15' d2 running off a sundown 2500@1ohm. I just wanted to know if its possible to run the zcon off the sundown @4ohms since the efficency is better and i am happy with 600rms since i will be buying a new car and i want less power but keeping the same equipment since i dont wanna sell/rebuy etc.

I am going to use a memphis 16 PRD 1000.1 amp to power a Fi Q12, I really want this sytem to sound nice so how would this amp work? If there are any better for the same price range please let me know. thanks C memphis Prd 1000.1

So in my electrical class my group and I are doing a project on MOSFET's and I will be bringing in some MOSFETS (blown and new) for some show and tell, then I wanted to bring in my amp (saz2000) and show that off but then I looked at the board and I was like umm maybe I should learn all the parts and how the amp works! so here is my amp's guts (i got the pic from another forum the saz2000 pre-sale one!) so here is what I understand (i hope i am not 100% wrong) on the far left and right sides those are the MOSFETS, the power supply are the 4 red coils, the caps are on the bottom center and top, the teal things I don't know (top center) the pre-amp is all that stuff at …
