Let's see if you can figure this out, because I sure can't. Sorry about how long it is, I wanted to make sure I was thorough. Here's some background: -I drive a 2006 Nissan Sentra. -I have a Fi BL 12 powered by a SAE 1200d in the trunk. Sounds awesome... ----My car has the "premium" sound system installed from stock . This means that a small Rockford Fosgate amp in the trunk is powering the front speakers. It also means that the signal for everything but the sub is being double-amped. You would never know though, the highs are clear as they were before. (More on this later) On to the real problem.. I bought a Kenwood Excelon KDC-X794 to replace my stock head unit…

I am in the market for an efficient amp to power 3 12" punch HX2s...Can anyone recommend a good/sturdy efficient amp for within $325? I need at least 1500wRMS. Thanks!

Have an Audioque 1200d that stopped working on me and I'm now looking for a replacement for it. I had no issues with the amp (until recently when I started smoking) so I have no problem going with the Soundqubed 1200d if thats the best option. I was about to order it but figured I would ask here first. Anyways, it's being used to push my 12" ICON. Any suggestions on a solid amp that will produce the 1200-ish watts under $300 shipped is welcomed. Thanks!

I'm a little bit confused about how to wire the RCA's. They have basically 6 sets of preamp outputs with some labeled mid, highs but also some sets labeled positive and negative. The manual isn't too detailed about using the pro setup except to connect all of them. I am going to be running tweets and mids up front and mids in the back. Plus a sub(which it has 2 pairs of outputs to as well for some reason). I will post some pix if necessary. Thanks for any help you guys can provide. I'm trying to get this done tomorrow as i will be working til 10 pm tonight.

I'm looking for a HU with a super clean look that has a decent amount of EQ capability, can take an aux source (planning on installing a carputer) plays cd's and has some good bass management. It's going to go into the expedition and power the stock speaks ATM untill I get a new front stage which is the next step in the evolution of my car remodel along with the car puter this winter and subs by next spring. I have no Idea what to look for in a good HU for Just audio management. the less bling and more function the better, I don't relly care what size it is but I do want to keep the cost under 400, at absolute max. I would be much happier at under 300usd. I have an olde…

Alrite so which one is better for the price to power a 12" BTL. the Crunch GP3000d Pro or the US amps Xt4000D. I am on a budget so my options are pretty limited.

Hooking my brother up with my 15" Fi Q (basic) and its being powered by a RD 1000.1D doing 1000 at 1 ohm. Looking to get an amp kit for him and I can't remember whether or not to use 4 gauge power wire or higher? Also, the amp has 30Ax3 fuses for a total of 90 amps so I'm assuming I need a 90 amp fuse for the power cable? Reason I'm asking is because the knukonceptz kit I was looking at comes with a 120 amp fuse. Just a few simple questions.

i upgraded my alternator to an iraggi 260 amp .... i had an excessive amperage 300 amp in there but it was not charging correctly ... it was only charging at 13.9 and would get voltage drops into the low 10s ... i sent it back because i thought the alternator was bad ... i sent my stock one to dom to build me one to work for my car ... i just put it in and am getting similar readings ... this time i am getting around 13.8 (best) and drops to the low 10s .... i understand my t40001 draws 400+ amps of current but i dont think the voltage drop should be that bad (drops like that within 3-4 seconds) ... i am pretty sure the battery is good ... i only have the front battery in…

I have decided to get 2 10 inch FI SSD subs for my Toyo Camry. Im looking for a cost effective amp to push them close to there rms. I see it is rated 1000w rms but if I can save a few bucks and only get about 600w-800w to each I'd be happy

I'm looking for a new Alpine and I'm considering the CDA-9885 for $280 or the CDA-9887 for $330. $50 more get's me the Imprint Sound and 24bit Dac. What's everyone's opinion on the Imprint technology? And what improves when going from a 1bit DAC to a 24bit DAC?

I'm wondering will a active head unit solve my problem. I have a jbl gto 1201.1 II and it doesnt have a subsonic filter. I probably going to get a Alpine 9887.

Would anyone on the forum have suggestions regarding fair market value for the following US Amps USA 2000x? I recently purchased a new set of Definitive home audio speakers and am looking to possibly trade rid my old set to a friend for the US Amps USA 2000x pictured below. I've been out of the car audio loop for quite some time and appreciate your feedback. Thanks-Chris

Hey all. I'm at a loss right now. I'm preparing for a build replacing my subwoofer. I will be using around 2500 watts of bass plus 250 watts of highs. I'll have one battery, but I rarely play the system with the car off. Anyways... Nathan (from Excessive Amperage) seems like a great guy and super nice, but I'll be paying $25 more for 20A less. The Power Bastards alt is 220A and the Excessive alt is 200A. Any recommendations? Comments/experience on build quality? Both come with an overdrive pully and a one year warranty. Thanks.

so i went to spl show and wanted to see what my two sq hds200 dual 2ohm that is wired for a 2ohm load and even checked them with d.m.m and shows 2.1ohms but my mtx thunder 1501d older style no elite suppose to do 1500wrms@2ohms with 14.4volts has 2gauge welding wire and at the car audio show it only clamped 844watts. Im wondering why is this and is there something im missing here and how to fix this to get my wattage up because my spl score in my 00 s10 ext cab was only 142.3 on dash http://www.termpro.com/asp/officialevent.asp?EventID=15579&Method=1000 name is david downs i entered the hardcore truck so i could have door open driver side and then unlimited car truck…

I been trying to do some research on some 7-7.5 rms amps but not really making a ton of progress. What are some good amps that's within this power range with the exception of dc. i know b2 m1s and ns1 v2 are in the category but what are some others than im overlooking? i need two budget is $3k

While sitting here thinking about how i keep reading about capacitor or battery topic.. this popped in my head. So, i am curious... With the new XS VCM, will this not only replace MLA but also capacitor use period? For those that don't know what an XS VCM is, let me briefly describe it. It is an add-on device for stock or aftermarket alternators that has an attached module that sits in your car. This module is set to any voltage in 0.1v increments up to 19.5v if your setup supports such voltage. When the VCM is used, whatever voltage is set, this voltage will NOT fluctuate...not fluctuate...not...ever(with slight exception below) In testing, it is shown that, for example,…

Hey does anyone know anything or have an opinion about this amp

So I've been researching ground connections, always trying to learn more about a subject, since I was upgrading some things its always a good time to refresh my memory. I've basically come across several ways suggested to make a good ground, and there are a few that stand out to me. 1) Using dielectric grease to seal moisture out of the connection area, with the idea that when you crank down on the nut to secure a ground lug to the chassis it will push this grease out of the way so the metal connects properly together and helps seal out moisture. 2) White lithium grease. I've seen this mentioned several times, but I truly feel it may be an outdated recommendation. …

How do I know what to set my SSF to? The Fs of my sub is 36.4Hz Box is 2 cubes tuned to 38Hz FS of my truck is 37Hz I can give you any T/S params you need, or you can get them from here: http://www.mtx.com/caraudio/products/subwo...ta_T9512-44.pdf (PDF file, 693KB) A direct answer of what to set it to is fine, but I would like to know how to calculate it, or at least a "rule of thumb" to go by when setting the cutoff frequency.

I just got my 12" H2 but I have spent to much funds lately. I still have to get my components and an amp for the components. I really wanted to get a 2500 amp but its not going to happen for now. So do you think I will be missing out a lot by getting a 1200 amp? I will be running it in a 1.5 cu ft sealed enclosure.

Just got one but how small are they really? It's 11-3/4 inches by 6-1/2 inches? Seems kinda small... Also, anyone have photos of their own collection?

I have an 05 Outback. Looking at a bunch of options. Best option seems to be Excessive Amperage who can do a 200A for 385. Anything over 200 supposedly will slip due to horrible belt wrap, and I only have a 5 rib belt. Mechman, Singer, Ohio Gen, and DC power are more cash for less ALT than the EA. So its either EA or possibly this? Stumbled across this. http://powerbastards.com/proddetail.asp?prod=Fitzall-220 Anyone heard or used one? Seems to fit WAY more than just my car. Which worry's me as far as how "drop in" it really is.

So, i had my meter mounted on the left side of the pocket below the HU using velcro. well, that was late last year (cool weather), and now... Hot Weather = the glue/tape on the back of the Velcro melting. so, heres a few pics of my dash. there is nowhere to mount it that i can see. you can see where the trim piece around the pocket is a separate piecs. i have to take that off when i need to get to my HU. so i cant mount it there. ANY opinions wanted. thanks!

You guys pick. Memphis amp or Viper amp. Viper claims to put out more power, the memphis is rated at 1100 but birth sheets that I have seen prove that it can put out 1200-1300 watts. I kinda thought it would look cool to have matching memphis amps. Just want to get more thoughts. Memphis http://www.sonicelectronix.com/item_3002.html# Product Description: 1100W RMS Class-D Monoblock Subwoofer Amplifier Custom Black Pearl Finish Fully Variable Low-Pass Filter: 50 - 250 Hz, 18 dB/Oct Variable Subsonic Filter: 20 - 50 Hz Bass Boost: 0 - 18 dB Gold-Plated RCA Connectors 4 Gauge Power Wire Capability Wired Remote Gain Control Power and Protection LEDs Thermal, Short Circuit, an…

I have heard a lot about welding supply and coppercableman on e-bay, what about wire and supply or electron beam (EB-flex) wire? Also I see that 1/0 welding wire in general is rated for 350 amps at 50 feet while 2/0 is rated for 400 amps at 50 feet. I don't expect more than a 20 foot run at most from my front to back battery so what size cable would you guys recommend for a Crescendo BC3500d at one ohm with a 300 amp external fuse rating? Lastly I notice there is an ultraflex cable available from welding supply (as well as directwireusa.com) that claims to contain 4x the strand count of the standard wire yet the amperage ratings are the same?
