ok ive been looking throught the "big 3" posts and i understand everything except for the block to chassi ground i cant seem to find the stock one on my truck. if i cant get to it what would be the easiest way to do this also would it hurt anything if i ran 2 1/0 from alt + to batt+?

Anyone have the specs or a link to TRU's new Steel line, Tru's webpage does not have the latest models. Interested in spec's on the S45. Was told to look on diyma but only found the S44 specs. Thanks

I have an amp with the following specs: 2 x 75 Watts RMS at 4 Ohms 2 x 150 Watts Max at 4 Ohms 1 x 300 Watts Max at 4 Ohms Bridged 2 x 125 Watts at 2 Ohms Electronic Crossover Network Bass Boost Circuit 2 Ohm Stereo Stable Tri-Mode Capable Gold RCA Inputs Power & Protection LED Indicators Advanced Protection Circuitry Soft Turn On/Off VU Meter Thermometer Frequency Response: 15 Hz-35 kHz S/N Ratio: 90 dB I know its not the best of specs in the world, but it is all I have right now so I want to make this work. I got a TC-1000 12" DVC 4ohm, so if I bridge the amp that is a 2ohm load on the amp. My amp says its only 2ohm Stereo stable, so I was thinking…

I am posting this topic for a friend. I cannot figure out what is wrong with this thing. Here is what is going on. Voltage remains steady. When subs are off the front speakers do not cut out reguardless of volume. When the subs are on the front speakers cut out at higher volumes. I disconnected one speaker at a time at the amp and ran each speaker separately and they front left cut out when connected and the front right cut out when connected. I checked all the connections near the amp and everything seems to be fine. The gains are also set below normal. What could be wrong? The amplifier is not bad because it would have cut out with the subs off.

I have an 07 Dodge Ram 3500 Mega Cab My head unit is: - Kenwood KDC-BT852HD. Which is 50W x 4 In my front doors I have: - Alpine Type R SPR-69 speakers. Which is RMS 100w & Peak 300w In the rear doors I have: - Alpine Type R SPR-60 which is RMS 100w & Peak 300w For my sub I have: - Alpine Type R SWR-12D2 which is RMS 1000w and Peak 3000w Now I need help on choosing an amp to power everything and I`d like to get the most out of all 4 speakers and sub. I suppose I should get an Alpine amp? An all Alpine system? If not what other amps are good? Please list the model number or link to it Also I`m not sure if I should get one or two amps, one for the speakers and one f…

I am gonna be running 2 sets of kicker ks 6.5 component sets,i believe they are 100 watts rms.i am looking for a decent amp to run them,my budget is up to about 200$.any suggestions?

Greetings out there. I have read many write ups and seen many videos about using test tones to set your amp gains with an o-scope. My question is when setting bass amp gains does it matter if you use a 40Hz tone over a 50Hz tone? Each topic on this has used a different tone but never told why. For those who dont know.. yes I am a so please inform me if there is a difference. Thanks..

so, like the title says, im begin to look into an active set up. right now i have chitty sony hu (cdx gt310.... first hu). im basicly looking to the option i should be considering when goin to an active set up. obviously im looking for new hu. my idea is to slowly work up the funds for it or put it on my xmax list. as a college student i really dont have the funds but im very interested in this hobby and i think this is the next step. well technically i will be deadening the front doors first and finishing the trunk. my plans are to sell my current hu and pg rsd components when the time comes ofcourse. i also need to run new rca's and clean up some power and gound wiring …

need like 2500w rms for the mt like 240ish (i guess?) @ 3 ohms for the pro60s. im most likely not gonna do rear fill, if i do, itll be off the HU. what you guys think? im tryin to get the amps ordered, so then i can start the box/amprack.

sooooo heres how the story goes. i got an amp a while ago, the crunch gp 2500d, and then i bought some subs, like the aq sdc 2.5s, but take a little more power (called TF X's if anyone is interested) both dual 4's wired down to 1 ohm at the amp. anyways, i'm underpowering them by a few hundred watts, and i'm looking for a replacement. in my searching i as offered an earthquake ph-d3 for a bit less than 300 rom a friend of mine, but i think he used to use it for spl comps a few years ago. anyways, the amp works great, and at 1 ohm does 3000 rms, so i figure if i'm easy with the gain i'll get the output i need, or i can match my current output at 4 ohms with 1300 rms. m…

I had blown one of my subs a few months ago so I unhooked everything and removed from vehicle. After doing some upgrades and getting new subs in, I finally reinstalled them yesterday. The problem I've ran into is that the amps aren't producing any sound. They power up and show that there on, but no sound. What voltage should the remote wire show? This is the only thing I can think of to check. I will say though that when I had a sub blow it blew the fuse between batteries and the amps where underpowered for awhile. Could this have caused internal problems? All help needed fast!!!

i was wondering if i will be able to hook my batteries up like this or is the only way is to daisy chain them? - - i know this is the rite way, but just want to know if its possible to do it the other way reason for askin is limited on wire at the moment

Like the title states. I need an amp to power 1 incriminator audio lethal injection DVC 4 ohm sub 600rms. I want something that's reputable and not something that is going to take a crap like that China stuff (no offense). Brand/ model names would be great, I know this isn't the 4 sale section but if you're selling something that's good and suites my needs, PM me with price, brand/model name, and condition THNX to all

When replacing in line fuses with a bigger size do I have to buy another holder or can I use the one I have now? Thanks

So I plan on getting a battery for in the back soon and I was curious as to if it will hurt my battery in the front by getting an AGM for in the back. Also do I have to go with something that is in the range of power my amps are taking or can I go with something along the lines of a XS Power D545? Roughly with both amps I'll be in the range of over 1800-2200watts rated.

I recently bought a pair of sundown SA 6.5 components and the amp i have to run them on is a Vibe Litebox stereo 2 channel. I was curious on the best way to wire them. any help would be much appreciated, thanks!

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?

Alright so I have a 95 Saturn sl2. I as wondering what to do with my power cable because I cannot fit It in between the negative terminal and the actual battery. So instead I have my power connected to my fuse box which..in my mind is putting so much less power and just not as hood as the direct connection to the battery. Is there like an extension to my terminal I can get or what should I do about this.. Sorry for bad Typing..using my phone

Just got in my new head unit, for the vehicle I dont even have yet! I sold the scion, but wont be picking up the new ride for another week...Priorities!

Hey guys im looking to try out the maxx link but i have a question for ya. Im gonna be running 4 kicker zx2500.1 amps and 2 18in Btl dual 1 ohm subs. The zx amps are 2 ohm stable and i was wondering if there is any possible configuration to have the amps see a 2ohm load once strapped. Also would i be better without the maxx link and running each amp to each coil? What ohm loads could i see there. thanks

Does any one have any experience with this head unit? Just wondering if it works well with a ipod. and how is the sound quality on it

Hey guys... I'm about to do the big 3 in my pontaic g8 and the batter is in the truck.. The alt positive is no problem but I'm trying to work out the engine block ground..... What are my options without putting the wire under the car..... Can I ground the block to the chassis and double up on the chassis grounding points near the battery?

what are some good amps that will put out 1600RMS and are for $400 and under.

What amp would be good to power two Kicker L5 Solo Baric 12s in the 150 to 230 price range? and are those subs good?

Does anyone know where I can find a list of all alpine head units? I'm trying to build a few period correct stereos and need some info.
