Hey Im thinking of selling my sony xm-5046's but have no clue as to how much theyre worth now. I was wondering whats a reasonable price. anyones opinion with prior knowledge of these amps would be greatly appreciated.

What are the differences? Let me in on the true details. What do they share & what makes the unique to each other

i stopped by a local pawn shop and they have a kinetik 2400 for 150. they said i can take it to autozone and have them check it out before i give them the money. is this a good deal????? the outside looks flawless with very minimal scratches and dings

I've had my koda 8's and ID cx62's sitting around for god knows how long. There is someone over at CA.com selling this amp http://www.caraudio.com/forum/showthread.php?t=171515 for 185 shipped. That's a really really good price for the power it puts out. Is there something wrong with MB quart? Why isn't anyone really showing interest? I just want to know b/c I'm about to pm him about picking it up but need to know what I'm about to purchase. I just want to put 150 to the kodas and maybe 100 to the ID's. Tell me what you think

Is the JL Audio A4300 amp a good match with 4 Infinity Reference 6822cf speakers? I got the speakers for free and just wanted a good cheap amp to power them to their full potential. Also is there something else you would recommend for these speakers instead?

While looking around at H/U's Saw this on Chrutchfield. Looks pretty interesting. Opinions? http://www.crutchfield.com/p_333ASTRDSM/Parrot-ASTEROID-Smart.html

I have done some searching around and have not found out what I'm looking for, I understand the calculation for volts on a DMM to set the gains properly. In my particular case, I have (2) Fi SSD's (800rms/each) and a Sundown SAE-1200vD2 (1200rms). Now what I have been seeing is everyone says to take the lesser of the two then do your calculations for proper volts on the DMM. So, would I use 1200 from the amp or 800 from (1) sub or 1600 for both subs?? Im guessing since my subs can handle 1600 combined, I would then use the 1200 from the amp, which would be 34.64v (dual 1 ohm subs and wired that way). Please clarify for me. Next question, I have several wiring diagrams for…

by any chance would anyone know what 2 hifonics bxi 2160d strapped do at 2ohms??

I just recently bought a pioneer avh5000 and I was wondering if there is a way to bypass it. Any help would be appreciated.

Do you think a hifoncs bxi2006 2000 watt amp can power a FI Bl?

NSBG-3100 Vs Kinetik HC2400 Which is the better battery?

I am wanting to put an aftermarket DVD player in my 2004 GMC Sierra 1500 ext cab. I have factory onstar and xm and want to keep both. I know that I have to get an adapter like this http://www.logjamelectronics.com/pacos2.html in order for it to work. What can I get to in order to retain the factory XM radio? I also have settering wheel controls. I know for the steering wheel controls I have to get a PAC unit in order for them to work.

hey guys. quick opinion thread. I already have my big 3 done and 1 run of power from back to front with 1/0. I have a DC HO alt on its way 200 at idle. i have 2X XS D3100 now and an optima red top onder the hood i will be replacing soon. my new setup will consist of 2X Sundown 2500D witch i already have. my sub stage is a supprise only some of you know lol. My question is... do you guys think with me upgreading all my wire to Welding wire is actually nessessary? my plan is to change my big3 with all 4/0 wire. and have 2 runs of 3/0 power front to back. i am not worried about the $200+ i am spending on the supplies i need including the wire. I am just cerious to see what …

I tried searching for this but couldn't find anything on it. I have a DieHard G34M and they have 2 terminals on the top Is there any difference between these 2 terminals?

Right now my setup is(see sig) and I have BAD voltage problems. I believe my problem is that I have a 2ga wire from the front battery to the back(came with the car,to lazy to change it) where I branched 3 runs of 4ga wire off it to my 3 amps. Now I was wondering if I ran 1 or 2 runs of 1/0ga from the front to the back would that cure my problem?

to run two kicker cvx DVC 4 ohm speakers (will be running them at 1 ohm). looking to spend between 300-350$ if anyone has any other amps they might suggest. Thanks!

Okay guys, i am looking at kicker zx750.1d its about 229.99 i was wondering if anyone knew of an amp thats just as good but maybe a little cheaper? any suggestions let me know! Thanks, Austin

Hey guys im about to purchace a triple alt set up from iraggi alts for my silverado. My question is should i get 2 350 amp alts and a 240 amp alt to help with at idle amperage or should i just get 3 300 amp alts. Ill be running 12k rms for a daily setup, thanks.

At work we have numerous rtas used to test the frequency responses of circuits. This is tested through an osciloscope input. My question is if I were to find a mic that had an osciloscope conenctor at the end of it would the rta work for what I want it to do?

I'm wondering the best thing I can do to help my situation. It's been ridiculously hot here in San Antonio this summer and my SAE-1200D just isn't taking the heat well at all. My Cadence TXA1000D never had a problem but I guess with the extra power this SAE has the heat is causing trouble. The amp gets VERY hot to the touch and after a while goes into protect. At first I thought I had a problem with the subs cause they would make a strange noise before shutting off but it cuts out even when my HU is paused so I don't think I have a subwoofer problem. Maybe mount something like 2 120mm fans on the bottom of the amp? How would I hook those up? Just wire them to the power/gr…

My birthday is coming up and id really like to increase my power to my sub as much as possible with $200. I currently have a power bass 400 rms at 4 ohms. My sub is single 4 ohm. Rated for 500rms. But id like to give it quite a bit more. Whats the biggest amp i can get for 200? I have a fi x12. In a ported box tuned to 33 ish maybe a tad higher. But i dnt play it at high volumes for more than maybe 10-15 mins. So im not too worried about anything blowing. I was thinking about geting a recone and try to recone it to dual 2 ohm.. And run my amp at 1 ohm... But thats kinda reckless because its only stable at 4 ohms. But if i set everything at 1 ohm and tune the amp with a dm…

ok here is the scenario: im running 2 BLs off of 2 1000.1 kickers and am gettin some dimmage(only when i turn it up), everything is stock question(s): whats the difference between a red top and yellow top(which is better reccommended if at all)? or do i need to get an xtra battery and/or cap? should i go ahead and attempt the "big 3 upgrade" to see if it helps any? thx in advance, and sorry, im noob when it comes to this stuff

So I mistakenly order a 4 Gauge and an 8 Gauge kit by accident of CCA from Knu. I was going to do a run of 4 gauge to the sub amp and 8 to the amp for the fronts. The sub amp is a Hifonics BRX2400.1D. Would the 4 Gauge be enough for just this amp?
