hi im going to another comp on the 1st (sunday). ive been running this amp @ 2ohms with my 4 12's. the ams specs are: 1100@4ohm 1800@2ohm 2300@1ohm 3000@ MAX well n e way, i was thinking bout running all 4 12's down to .5ohms. how long do u think i would have b4 the amp went into protection or overheated? i called up PA and they said that they never tested it at .5ohms. thanks.

hey guys i just drove back from work (i usually take the train) i was listening to my music the whole way home with the volume on 21 for almost 2 hours by the time i got home my sub was cutting in and out and when i got home the lcd screen on the amp said "hot " "77.9" degrees Celsius ( i knew it was before i looked) i know that my gains are not high, is that normal cause of the long duration? my stereo is an alpine cdx 9884 i believe goes to 35 max volume and my amp is a alpine mrd -m1005. what do you think guys? thanks again Billy

I have a samll problem and maybe someone here knows what is happening. I have a line driver on my amps so here it goes. I turned the gains on the LD up to about 1/2 way. I then proceeded to set the gains on the amps using a DMM and 50hz test tone to volume level 26 on my HU. Everything was good until I played music. It doesn't seem to matter which song I play. When I get to about 22-24 (depends on song) the sub amp cuts off. It's not in protect mode it just turns off entirely. My door/dash speakers warble, then go to producing a clicking noise. If I turn the car off and let it sit for a couple minutes, everything works fine when I turn it back on. Keep in mind t…

will a 130amp alternator suffice for a SSA ZCON 15 D1 either at .5 or 1ohm on a Crescendo bc200D and some other goodies down the road or would a 200amp alt be better

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

Say I have an amp that has 2 power and ground inputs. Say if I just use one with twice the size power wire is that ok? Or is there some important reason that they are split up to begin with? Fast advice is appreciated.

I'm just wondering what are the pros/cons of using a dry cell battery, than a wet cell battery. I need to get a couple of batterys and need to know the differences between the two so i know what to buy.

i just found out this sub has a subsonic filter set with chips tuned at certain frequencies. i dont know what mine is but apparently it's affecting my lowend responce from my subs. an installer told me spl competitors use these chips to keep from blowing their subs when usu=ing ported encloseurs. he said my amps sounds like the filter is set at 40hz-nedds to be set at 25hz. i listen to mostly metal but i like the ability to get low with certain synthetic beats(808). im using a dqx as my sound processor- i have my pmf set at 20 and my mid/low at 90 i just cant think of anything else to cure my lowend blues. im using 2 idq12's in a sealed 1.8 cubic box in the back of a 2003…

i have been trying to decide between these for a while. since i'm new here i thought i'd see what you guys perfer. 1)pioneer avic d3 - almost bought this one. i like pioneer, love how it looks, don't care about the single slot since i don't care about nav. the 2v preout thing killed it though. 2)eclipe avn5510 - the only thing that keeps me from buying this is thinking i can get something just as good for cheaper. 3)jvc kw-avx800 - the underdog. features look great, don't care about nav, the price is right. but its a jvc... thoughts/suggestions?

Ok so I have done the Big 3. Have a jeep grand cherokee. Found out the alt stock is 110amps. I am running a 100.4 amp and an alpine mrd1005d. Looking to get a deep cycle battery up front and a bigger alt. Battery i have up there now is 11 long and 7.5 wide. I looked at the battery basket and measured 13 long. I was thinking a powermaster d3100 up front. Just am trying to brainstorm some ideas and figure out a few different product choices. Also the Sea tweeters sound very nice. Barely need any power to get loud which really surprised me. Almost got those Excel mids dialed in and the midrange clarity is def worth it.

Alright so I am wondering which amp would be better for my setup. The SAZ 1000 or SAE 1200 hooked up to a BL 15 wired at 1 ohm? I know the SAZ is more of a performance amp and the SAE is more commercial I guess. But which one would power the BL better and not cause me to worry about blowing my sub or frying my amp?

i want blue tooth/ipod/changeable backround pic, the ipod is most important and SQ. what i have is in sig. i have good stuff and want the best deck for SQ. they both have the options i want. i think the p980 has a better screen and i think the ipod on the x991 is better. no one around me has this on display so I'm buying blind. please help me

older 4 channel I have I might sell, trying to find all the specs on it help a brother out?

I currently have a 90 amp alternator, im not sure if i should purchase a HO alternator (150 amps). During the week i will be doing the big 3 upgrade along with purchasing a new baterry. The battery im getting is a Deka Intimidator AGM battery: Group Size 78 Warranty 72 Month Chemistry AGM Cold Cranking Amps 740 Cranking Amps 850 Reserve Capacity 120 Amp Hour Rate 55 The sound system im going to be adding is 2 12 Fi BLs and a hifonoics Brutus BRZ2100.1D. So, do i stay stock or go to HO alt, moneys tight so id only get the new alt if its absolutely necessary.

what would be a good choice for an amp for type r. im not to sure what im going to go with yet. either two 12"s or one 15". any suggestions? thanks.

Does anybody know where I could find some free wiring diagrams for installing car stereos? I install a lot of aftermarket cd-players for my friend because he owns a car lot and having a website that would show me what is what would really speed things up. I am about to put in a DVD screen into a 2001 Caddilac Deville and was wondering if anyone knew where i could find the diagram for the speakers wire colors. Any help will be appreciated. thanks

http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=263-683&scqty=10 Does anyone have experiance with these? And how secure are they? And is there anyone that makes buss bars on here. I think I remember someone a few years ago ofeering this service but I could be wrong.

I have 2 american bass hd 15s an starting off with a crecendo 2000d till i get another one.i have 1 redtop opt i want to put under the hood an a yellowtop opt in the trunk.i want to no will i b ok with this bein thats its 2000watts or should i do more ?

i have 2 batteries up front right now and plan to add some more wattage to my system. i am thinking of building a bracket ot hold a dedicated alt for 3 AGM's in the back and run 2 lead acid up front for the rest of the vehicle. however i wounder if this is necessary, is there a way to have 3 batteries in back and 2 in front with a single alt and have it setup for the stereo to only pull power from the rear battery bank and have no voltage drop/draw from the front 2 batteries for the rest of the car? i was thinking the only way to eliminate voltage drop to the factory electronics was to get a dedicated alternator and battery bank but i thought id ask here before installing…

Im completely new to all of this..but I was wanting to put 2 12" Fi SSDs in a 2003 Chevrolet Trailblazer. But I don't know what options to get and what amp. I have about $600 to work with and still have to buy the subs, any help would be very appreciated

Well i just dont feel my arsenals are getting all they can from my Autotek MM1400. I am looking for a good 2000 wattrms amp. I really dont care about the brand and dont want to spend a tone of money. The autotek is a good amp but i know my arsenals can take much more. Any suggestions are appreciated. And yes they are already in a dual port dual chamber box. Also accepting offers on the Autotek.

I have 2 FI BL 12's hooked up to a Hifonics 2500, running at 1ohm. They seem to max out with my stock electrical (granted i have the big 3 and 2 yellowtops in the back) Am i getting the full power out of the amp? I hooked the subs to my buddies car who is running full electrical and 3500 rms and it was insanely louder. What can i do to get more towards his level or atleast max out my amp to give the full 2500 rms to these subs...

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

Hello, I've been searching for a long time but what I found seems to be too light : not enough power when I burn it on a cd! Can you give some links, please? at least a 50 Hz test tone for the sub, and a 1000 Hz one for the speakers. BTW, do you all set the gains like that, or can you use some music instead ? Thanks
