Both my amps were working fine “twisted sounds 150.4”, but since one of the rcas outputs broke off I decided to change all to Tiffany style rcas. My issue i’m having now when I try to adjust the fader on HU to front the rear speakers still play but little lower & vise versa & balance is the same issue. Also when I turn on my vehicle it has engine noise through speakers now. The single solder between ch1,2 & 3,4 is + & the duals above them are grounds for 1,2,3,4.

hey guys ive been going thru alot of amps lately and i was set on the memphis mojo amp for 4000wats but now i see alot of guys using hifonics amps . when looking at prices i found a 8000watt hifonics for the same as a memphis mojo 4000 and the hifonics amp had better protection agianst short circuiting and a crap tone of other features. then the memphis amp has only 4000 and very little features as i see . so my question is what would u guys do i got links below to the amps and prices . do you think 8000 is to much for 2 18 btls fully loaded ? could i burn them up ? hifonics - http://www.ikesound.com/hifonics_xxv_sampson memphis- http://www.woofersetc.com/index.cfm?fuse…

I just received a set of fosgate t1 components. They have a bi amp switch on the crossover...this is new to me I've never done it. I eRad the manual and it appears I need either a 4 ch amp or 2 -2 ch amps. So I switch it to biamp 'on position and basically run the tweets with a set of channels and the miss with another through the supplied crossover.. is that it? What are the advantages of doing this vs not bi-amping?

hello Whats up with the 2007 Crunch (Ground Pounder) D class amps? Do they do rated power(if so) how many volts to get rated power? Thanks

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?

So I couldnt pass up the deal on the SA line on here and purchased an SA-12 last night. Now it needs an amp. The car has a small alt, 70 amps. I want to keep it all under 1000rms. I will be running a 2 channel that makes 140rms total so I'm looking to give the sub anywhere from 500-750rms at 2 ohms. 600 would be ideal for me. My budget is 220 with shipping. What would you suggest? So far all I can think of is either an MB quart onx 1000.1D, a kicker ZX500.1 or a DX1000.1 (makes 50rms more than the ZX)

i email dc sound lab and they have been really slow at getting back with me. im looken for the price of one of their 2k amps. does any one know their prices?

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…

i contacted maxxsonics and i was told the 2610 puts out 1700 watt rms at 1 ohm at 12 volt. does the 2610 put out rated power? (i want to power 2 15 l7 rated 750 watt rms each)

Every site I've looked on says you can't put a double din with out modification. So if anyone has pictures of their build and how they did it that would be great. I don't want to jump into doing it and mess something up. I also don't want to have to pay someone to do something i could probably do on my own. Help!

Alright.. So my Iphone has decided to stop working with my head unit. When i plug it in, it will either automatically go to error-01 (communication error). BUT, it also does something else I find very strange. It will sometimes play the very first song on my ipod. Doesnt matter whether I go to playlists, or certain artists, it will always switch to all songs and play the first song according to alphabetical order. (My headunit doesnt let me control songs through my ipod, i always need to switch using the head unit which is normal.) Ontop of this, if it starts playing the first song, i cant skip it, fast forward or even pause. This all causes it to go into an error-01…

Hey guys. I just got a Rockford T2000 today and I am a little confused. The birth sheet says it puts out more power at 2 ohms than it does at 1 ohm. Whats up with that? Here are some pictures of it.

I recently had been in the market for a DSP, and ran across this pice of equipment. The PPI DSP-88r and some input from fellow car audio nuts. Is it worth the $209 bucks. Pros. And cons. Thanks in advance

I am just curious I have been digging and come up with nothing. I know its not really good to underpower subs..... lets say on the highs and mids the amps tuned according to desired but the powers not there....... bad?

going for a simple sq based system with components up front and a single diyma 12" in the rear. Looking at a pair of MC300's (150x2 or 500ish bridged) or a pair of Xterminator Xt1600.2's (125x2 or 600ish bridged). the UsAmps are cheaper but they are the lowend line while the M class is the top of line that they offer. What do you guys think?

Looking to get a new 5 Channel Amp, right now I'm Looking at the Alpine V9, JL 900/5 and the Arc Audio XDi850.5. Is there anything else on the market I should be looking at? I'd like to stay with in the 700 - 900 watt range.

So I have a SoundStorm (SSL) EV4000D. I've had it for about a year and a half, and never have had a problem with it, except that I have blown two Subs with it. The first one was a Pioneer TS-W3002D4 which lasted about 8 months and then the most current one which blew today was a Kicker CompRT12. So i need suggestions of what kind of sub i should get because obviously the last two were a fail. I want something that will thump my price range is up to $250. Hope I can get some feedback.

Okay fellas. I need some help with this one cause i'm finally at the point i have no clue what to do. I have an 03 Ford Taurus. Im running two RE SX 12D2's on two Lunar L1500's and Rockford Fosgate Power 4004. (If you wanna see my amps heres the link: http://www.lunaramplifiers.com/product_3_2.html) Ive heard all about the big 3 upgrade and i wanted to do it. But, the damn power wire runs through the front fuse box as well as the alternator wire. Making it virtually impossible to do it unless someone can help me with that. Seeing as how i was faced with that dilema, my problem arises. I've read and researched bats and caps and my original setup had a 800 Kinetik in the …

Anyone own any of these? Can I get 4 bandpassed outputs with it? I need 3 -way active... 2 outs for tweets HP, 2 outs for 4" BP, and 2 outs for 6.5" BP.... most crossovers only have 2 HP, 2BP, 2LP.... but I need FOUR bandpassed. Anyone selling any?

Has any one here ever used one?? I was taking a look at it today. One thing i would like about it is i could put it in my trunk and only have the Ai-net cable running to the rear from my deck, and shorten up the rca's going to my amps, also it pushes the pre outs to 4v. It has an adjustable 5-band parametric or 7-band graphic equalizer. What is the difference between the two types of equalization? What i would really like to know is does the Multeq feature work well. Any info will be help full below is a link. Thank you. PXA-H100 IMPRINT

I have two U.S. Amps that I have had for years and I am wanting to get the specs on them. I had them installed in another vehicle that I recently sold and I am reinstalling them in another vehicle. Before I sold my other car the 150 fried which sucks, but another reason I am wanting the specs is to find out if it would be worth fixing. The first amp is a US 150 the other is a US 25.

Need some advice, I need to purchase a 4 channel amp the choice between sundown 125.4 or ice 150.4 The only thing that's holding me back from buying the sundown is I've just read its a D class compared to the SPL ice 150.4 which is a a/b class. Would there be a big difference in sound quality on my mid & tops? I use a sundown 1500d v3 on the bass but I need a 4 channel to go with it. Thoughts please

Anyone know?

I will be running a 15" SI Mag in a 3.5cuft box tuned to 30hz and should be running a set of Hybrid Audio Technology Clarus C61-2 components. I'm trying to achieve a nice SQ oriented set-up that can still deliver a nice little kick. I have it narrowed to either: The Audison LRX 1.400 for the Mag and the Audison LRX 2.250 for the components. http://www.woofersetc.com/index.cfm?fuseac...Product_ID=4224 http://www.woofersetc.com/index.cfm?fuseac...Product_ID=4287 Or The Focal FP1.800 for the Mag and the Focal FP2.150 for the components. http://www.woofersetc.com/index.cfm?fuseac...Product_ID=4481 http://www.woofersetc.com/index.cfm?fuseac...Product_ID=4480 Can anyone help…
