  1. Hi there, anyone knows anything about this amp? I saw that's it's rates 2.9kw @ 1ohm, that's max or rms ? I cannot find any information about it. Nothing on the amp performance, and on the forum is one topic from 2007. Guts in the attachment Thanks a lot for any information.
  2. 2 subwoofer 2amps for each subwoofer, stock battery stock alternator. Amp: Alpine Mrv500 Subwoofer #1 Renegade 12inch Subwoofer #2 Pioneer champion series Ts-W309D4, wired dual 4ohm Can each amp handle these subwoofers? I'm only asking because my Apline Mrv-500 get to hot to touch, so I am concerned. Both amps running off the stock battery with a distribution block for the power cable. Ps don't ask why I have 2 different subs, the other pioneer blew...
  3. Hey everyone. I have 2x audiopipe txx-bdc4 15s rated at 1400 watts rms on 2 strapped audiopipe apdli2000.1d amps 2000watt rms each 8 guage wires going from subs (series parallel 2ohm dvc = 2ohm total / as split final 1 ohm each) and a 6 guage from negative to negative on strapped amps. ( I had it laying around.) I notice master amp stays a bit cooler than the slave. The amp manual also states you should just the same gauge wire from negative to negative when strapping. Why? And could the bigger size be causing this effect? Thanks a ton!
  4. So I’m getting no output from my subwoofers. Brand new pioneer deck and brand new audiopipe 2k. I have 2 d4 12s wired to 1 ohm and that’s what it reads at the amp when the car is off. But when I turn the car on it reads -2 or -3ohms so that’s obviously why I just don’t know what to do I’ve tried everything. Tried 3 diff sets of rcas
  5. I have had my cab 1600.1 for a while and worked flawless. Let it sit for a while and turned it on and it and it was sending a full wide open signal to my subs at a 50-60 htz test tone. I unhooked the rca's and no change. I took the back plate off and nothing looks bad/burnt. I have good electrical (power and ground). It just came out of nowhere. Any ideas??
  6. hello I recently purchased a distortion detector and the problem is I have a BMW 3 series and it does not show the volume level, How would I use this properly without knowing the acutally volume level that its at?, it's the navigation headunit type, Plus if I remove the subwoofer speaker wire from the amp, the door speakers still play loud from the Cd tracks is that normal ? becuase in YouTube videos i see online i dont hear any sound while they set their gains. 2 Amps: Mrv500, do I set the LP filter back to 80hrz after its tuned? 2 subwoofers: Pioneer TS-W309D4 12" Champion Series Subwoofer with Dual 4 Voice Coil
  7. When strapping amps do I need to have a power cable to both of them?
  8. Alright, i am sure you guys have heard this many times before. I have 4 18" FI BTL N2 subwoofers (V1) and I want to install them in my living room. Being dual 2 subs... I could wire one to one amp at 4ohm in series. So, guess ill need 4 amps. Any suggestions? i have been looking and found a few dayton audio amps.. I havent found anything that does around 1500 watts rms at 4 ohm. I am assuming this isnt common in home audio? Or will i need to hook up my welder to my 750.1? Lol.
  9. i have 4 kenwood kfc 6x8s that are 80 wrms. what amp would be best to power them. I was thinking about getting the rockford t400-4 which is 60wrmsx4 but theyre very underrated and most get around 80wrmsx4+the power from the which is about 22wrms. would this be too much to power them with and how should i set the freq and other stuff on the amp? thanks EDIT: i also found a memphis audio srx 4.300 this looks a lot better
  10. i am soon to purchase 3 type r 10's the new ones that run 1000 watts rms so please help me pair an amp or or amps to these subs and any other helpful information would be accepted as well. (please do not troll me i am 16 and on my 2nd system)
  11. I have a quantum 4000 pushing 2 arc 15d4s in a sealed box I did a bandpass in my 03 honda accord. I know that amp isnt giving me 4000 the fuses are only 120 amp total if I went with the dc 2.0k would I notice THAT MUCH of a difference? I hit 135db with this system what can I expect with the dc?
  12. Hello all! I got a RF P3001 for sale. Nothing much to really say about it besides that it is in fully functional and working order! Great little amp and has served me well! Im just needing the money to upgrade! Not stable at 1 ohm, does 300 at 2 ohm rated. The birthsheets say somewhere around 395-405 rms. ready to sell! $60 plus shipping. Any questions let me know! Will take trades! Looking for 1 10, 1 8, 1 12...other amps... 0 gauge wire... Tweeters...AQ or Crescendo mids!
  13. Not trying to get stuck on a topic everyone has seen and read before but im looking for the best amp out of the two ive found to give me enough power and fits within my small budget. The amps are re audio ctx 3200.1 which is a 2013 model pushing 1200 rms at 1 ohms or the hifonics zrx1800.1pushing 1800 rms. They are the same price.

  14. This will be my first post here on the site. Im currently running the American bass xfl 12" subs in a q bomb pro box off a hifonics brz 2400.1 with a red top under the hood in a 95 Avalon. So I need help designing a box where my subs face the rear but my port is facing the cab. I want the port in the center bc I want it blowing through the "arm rest hole" of the back seat. I will be posting a few drawing of what I have drawn up. no measurements yet, just ideas im playing with. This box I've designed is an L shaped ported box with the port in the back. what do you guys think??? will it work?? *******The blue represents the air flow. I also drew braces in the back....
  15. Okay... I know most people hate capacitors..but i like them. Anyways I have two twelves and two tens. I have a 10 farad capacitor. One of my amps only has one set RCAs and the other has two. Can anyone help me on wiring this? Any help would be greatly appreciated. Thank you, Wade
  16. i was looking at sum amps and the precision power amps have excellent specs and best of all BANDPASS capable!!!! i wanted to know if anyone here has used or is using the amps in the Black Ice series here are links of the ones im saying PPI BK800.4 http://www.sonicelectronix.com/item_43834_Precision-Power-PPI-BK800.4.html PPI BK520.4 http://www.sonicelectronix.com/item_43833_Precision-Power-PPI-BK520.4.html are they good for the money? decent sq? power rating seem correct?

  17. im lookin to buy a soundigital sd16k have cash, and or trade (nice BNIB 4k amp) lookin for asap.
  18. Hello Everyone, It's been awhile since I've been on the forum, but I'm in the midst of my new audio build and I've run into some issues. I'd really like help to problem solve these issues. I'm running an active 2 way front stage and a 12" sub in the rear. First things first, here is a short run down of the parts related to my issues: H/U= Pioneer 80prs. network mode. internal amp off. running directly to my 4 channel amp and sub signal to my monoblock. 4-chan amp: Jensen Power 400.4 rated at 75w rms @ 4 ohms per channel monoblock: Hifonics brutus brx1600.1 First issue. I was beginning to set the gains on my amps, but when setting them I can only seem to turn the gains about 5 to 10 degrees above minimal gain before distortion on both amps. I'm using a DSO oscilloscope to see distortion in the signal. On the 4 channel amp, I measured 4.9v from the deck and nearly 17v out of the amp. Does that sound right? The math seems to check out. 17v on a 4 ohm load gives 4.25 amps equalling 72ish watts. Is it normal to only turn the gain knob a few degrees? Issue two. Stick with me for this one. Since the 80prs' high frequency outputs lowest setting is about 1.25kHz, I used the midrange rca's to set the gains for the tweeters and mids. I used a 100hz and 1k Hz test tones at 0db , -2.5db, and -5db. During this test is when I noticed an issue. I had the drivers side speaker wires unplugged from the amp and all rca's unplugged except the driver side mid rca. I had that plugged into channel 4 which is set up to be the driver mid. (note: channels 3/4 share a gain and 1/2 have a gain, so 3/4 are mids and 1/2 are tweets.) When I played a 1k Hz tone into channel 4 (driver side mid) I heard an audible, but low volume tone out of the passenger mid. I played pink noise to test and I heard an even more noticeable static sound out of the passenger mid. Now I might be wrong, but if the rca for that channel is unplugged, shouldn't that speaker be completely silent? Just another thing, I left all the gains where the scope showed clean signal, where I left it was set using a 100Hz -2.5db tone at max headunit volume, and playing music at max volume the sound is what I would call regular driving volume. It is not loud. You can definitely talk to the passenger with the volume at max. There should be more volume. In the previous build, I had the same amps and a pioneer avh double din and the gains were set by ear. That system got so much louder it's laughable. The last build the gains were set at around 75% with no audible distortion. Now they are at around 10%. So I'm curious, bad amp? bad scope? Help, Please.
  19. Hey guys I had a question about car audio builds and I figured what a better place to ask it then a forum dedicated to car audio and all that fun stuff. I just got rid of 2 12" Pioneers because I wanted to upgrade my system. I am looking for something within the $250-$400 price range as a whole. I drive a 1999 Lincoln Town Car, so the trunk has adequate space for a big set of speakers. I have a couple ideas of maybe what I want but i'm not sure which one would sound the loudest for the price. I was looking and I found a couple different setups I like, I'm not sure if I'm allowed to post links or not but for my sake I will not unless notified I can. I want to get a 15" DVC Sub and A monoblock amp. Any suggestions? If I'm allowed to post links please let me know so I can show you what setups I was going to look into buying.
  20. I'm not a pro in this area so please be patient. I recently had my sub installed at a shop in my area along with an amp and a lc7i. Whenever I crank the volume up I get this low rumbling sound from the sub. It makes this noise even when there is no bass in the music I'm listening to (i.e. intro, outro). However, it doesn't make this noise while the music is paused. When I looked in my trunk i noticed that they ran all of my signal cables with my power and ground, so I figure there's a ground issue. I went back to have it looked at and the guy told me that since my car is so small it will make that noise due to the amount of bass that I have, and if it was in the trunk of a small car instead of the back of an suv I wouldn't hear it. None of this sounds correct to me, am I correct in assuming that he was just being lazy? I also noticed that my bass knob does not turn my amp all the way off. When the knob is all the way down I can still hear my sub, just at a much lower volume. Is this normal? Oh yeah, due to my sub being a 2ohm and my amp not being 1ohm stable I am forced for now to operate at a 4ohm load. This is only pushing 750 watts to a sub that 1100 watts is recommended for. The instructions say that I can safely power it with 500-1200 watts rms. Could this be a contributing factor? 2009 BMW X3 single Kicker Comp Q 15 Kicker ZXS1500.1 Audiocontrol LC7i
  21. Hello, i have a quick question i would appreciate the help. I ordered a 220 amp spx dc alternator, do you think it would be enough to handle a 2000 watt hifonics amp Along with 2kicker L7 15s.( soon upgrading to dc level 4) i bought a new yellow top optima That i could install when i get my alternator.
  22. i am only 16 dont have a car or license yet but i want my system to be ready when i do! i am installing a fan onto my boss 4 channel amp the thing is a joke but i have never fiberglassed before so i wanted to try it im saving for a nicer 4 channel but oh well its better than running it off my head unit but here it is my first time ever fiberglassing [/img] layed out where to cut [/img] cut the hole [/img] fiberglassed did a ok job.. [/img] sanded and bondo [/img] primered it [/img] amp guts its so cute lol still have to do a few more primer coats and paint it but thats it so far:)
  23. This amp has a loose set of rca inputs the round exterior(neg) of the rca wiggles in the bracket, it makes a static sound. even with grounding both rca's it doesnt help really.
  24. My current system is an Alpine CDE (forgot the exact model number), Clarion EQS746, 2 Skar Audio VXI65 component sets, 2 Skar VVX 12's, an MB Quart 125.4, and a Skar 1500.1d. I have alrady set my gains with a DMM, but I have access to an oscilloscope at school, and plan on tuning my system with that sometime this week for better accuracy. My questions are: How do I find the clipping point of my head unit, and equalizer combo? I'm assuming I can use the procedure described in the DD-1 manual on how to find the head unit's clipping point through the amplifier. It basically says to play a test tone with the speakers disconnected, the gain turned all the way down, the probes hooked up to the positive and negative speaker outputs, and then it says to gradually increase the head unit volume until distortion is shown on the oscilloscope. I plan to do this procedure with the equalizer flattened out, and its volume and subwoofer levels turned all the way up, using a 1kHz -0dB track for my mids and highs amp, and a 40Hz -0dB track for my bass amp. Then I would keep the head unit at the average of those two numbers. Would this be a correct way for determining what volume my head unit and equalizer combo clips at? Any and all help is appreciated. Thanks in advance!
  25. I need some help on decision which amp I should get. Ive narrowed it down to crescendo 3500, DC 3.5k, q1-3500d1, and a 1500bdcp...for now I need to run close to 2000wrms at 2 ohms but will be looking to get new subs to play at 1 ohm and more watts in the near future. which of these would be best and any other suggestions for around the same price as these?
