I have some pioneer speakers that rms at 40w and I have three amp choices that are in my price range what would be better Mb quart onx4.60 @$99 Alpine mrp-f300 @ $149 Kicker dx200.4 @ $149 Please help

I'm looking at possibly running three 4 ohm subs, which would give me a 1.34 ohm load (of course, you all know this already ). How much power would I lose if using an amp that does its power at 1 ohm?

Does a car battery need to be grounded to something in order for it to work properly? The reason I ask this is because a friend and myself are doing a school project (we have to design an entire business), and we thought it would be cool to make a movable car audio display. It would contain some OEM speakers from my Lumina, as well as my friend's Kicker L5 8", Audiobahn amp, a Kenwood head unit I've got laying around, and my car's battery that I'm soon to be replacing. We're thinking of hooking the amp and H.U. directly to the battery (well, fused of course), with a switch on the H.U.'s power lead so that we can turn it on/off that way. The ground for the amp and H.U. w…

I have had one of these guys sitting around in my room for a while now. The only info I've ever really found was this thread from 2006. Anybody have any other info?

so i have a us amps md1d amp hooked to a ten inch re audio sx. i had it wired to one ohm and a guy that i was talking to said i was probably pushing closer to 1400 watts instead of 1200 watts at 14 volts. is this true?

Anyone know of a good amp repair place that might be able to fix an old Mark Antony 25OPCM? I found a phone number for Concept, I believe they bought them out years ago--but haven't had a chance to give them a call. I would REALLY like to get this amp repaired if at all possible.

whats the difference between a graphic eq and a parametric eq. also whats the advantages and disadvantages or each

got a sae1200v2 wired to 1.33 and my mids and lows running off a mb quart pushing 125x4 at 4 ohms will one run on 1/0 awg be enough and just split it inside the car or do i need more than that thanks trying to order wire during 5 dollar shipping from knu

My system was finally working right all together. I was on my way to my apartment (3 hr drive), so I had turned the bass really low so it wouldn't knock my radar detector off the glass. I was just driving along and heard a loud bass hit all of a sudden. It was really weird, kuz the bass was pretty much to where I couldn't even hear it and I guess I didn't notice kuz i had turned it down alot. So the bass hit really hard, then stopped. It did this about 2-3 times, just really odd sounds and extremely loud...like not going with the music that was playing and far far louder than I had the bass turned up. Anyway, I got home to check it out. I can turn the subwoofers OFF…

Hey everyone, I'm looking for a deal to buy an XS Power D975 as a replacement for my Civic's group 51 interstate. Although, I can't find anywhere that has deals on even the brand. Any help? Thanks

i'm thinking of getting a second eD nine.1. they're 900 watts stable at 2 ohm, and 1200 at 1 ohm. if possible i'd like to run them both at one ohm, im pretty sure i have the electrical system for it. question is, if i wire a dual 4 ohm voice coil sub by itself to the amp its either at 4 or 2 ohms right? no way to get 1 ohm load from a single d4 woofer? could someone maybe give me a crash course in wiring? i think i would need d2 woofers to get 1 ohm from 1 speaker right?

I have a cheap 300w amp that I plan to run to my doors and 6x9's in rear deck. I already have a run of 1/0 to my 1000w mephis amp. I was wondering if it is a good idea to run a short run of about 12-16g wire from the power inputs on the mephis where the 1/0 is, and from there to the power inputs on the 300w to keep from having to put in another run of power cable from battery to the trunk. I tried this already just to power the amp and it worked, but I didn't have any speakers wired to it. Would this be logical, or would it mess something up?

So I am attempting to install my upgraded alternator and big 3 this is a first time for me with both situations. Everyone from here has been super helpful so I was hoping you can bail me out since my car is in pieces. I have currently removed the original alt and put the singer alt in that I purchased. I have not connected any wires yet this is where my confusion has started. I have located my grounding wire from engine to battery and will upgrade it which is one of the big three. Now the other two is where I am getting confused. 1.The alt I purchased from singer has an upgrade to increase my voltage and the device he put on has will not allow me to re attach the two c…

well i got my sub in today for my little mini build im doing and now i need to decide what amp i should go with to power it. the sub is a Fi SSD 12 D1 with BP cooling. I was thinking of running around 900-1000 rms to it at 2 ohms. So the question is what amp would you guys think would be good for this? The budget on this isn't much. probably around 200-225. thanks

just wondering if anyone knows anything about the Xenon line, prices are falling on them (posted link in classifed section) and same for the subs, I know I should wait until CES, but I am an ansey one

Hey everyone i am new to car audio and am planning on doing a big setup. I was planning on getting a 250 amp alt with 2 yellow tops powering 2 audio q 2200 connected with 2 12 inch fi btls. My question is that do i need fuses? If so how big do the fuses have to be? How do i know? Where do i need a fuse the most? THANKS

I have an Eclipse CD-8053 CD player which I love. It have a built in Crossover, However it can not do everything I need. I need a outboard Crossover that will work in conjunction with the Eclipse r all by itself to control a 3 way or 4 way system I have a SI Sub CDT EF8 Midbass CDT ES520 Components. Now either I need to break the audio line in 3 spots and use 3 amps and let the Components Crossovers do the work between the 5.25 driver and the tweeters, Or I can buy a 4th small amp to run the Tweeters off the new crossover. My Main concern is that its adjustable, and will not introduce any new noise, in other words a SQ piece! Let me know if you have any suggestions. I …

Gonna be using this for my sub amp, probably on a new eclipse sw8000 10" until my Diyma 12" comes in.

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!

Here in my next build, I'm going with 4 batteries, but am unsure about which to use. I'm going to be building a wall in my 2 door Chrysler Sebring....2 Sundown Audio 3000D's, 1 15" custom Nightshade(lil bit of tweaking) and a Sundown Audio 100.4 for component set. I'm running all 0 gauge Kicker Hyperflex wiring, Optima Yellow Top up front with big 3 done with the only alternator available for my vehicle...a Load Boss 160 Amp alternator. My question being....I know of all these battery companies....and I've used Kinetik but want to go a different route. How are Powermaster...DEKA Intimdators and any other high amperage brand of AGM batteries stacked up against eacvh othe…

What can happen if to many things are hooked to one remote wire? . . . Every once and a while my amps will shut off like there protecting and sometimes the cd player will shut off but volts will be in the low 13s . Could this happen from alot of things hooked to one remote? . I have both sub amps. My 4 chan amp. An eq and both volt meters all from one remote

I plan to wire my sub to my amp like this, My question is, would it be the same if i ran 1 positive wire out of 1 positive terminal on the amp into 1 positive terminal on the voice coil and the other positive terminal on the amp to the other positive terminal on the other voice coil and the same for the negative?

hey i don't understand why visions in my town when running the speaker wire to the sub used 16 gauge and twirled it around it self so when i unwound it there was probably 7-9 ft just going to the box does twisting the wire do anything or are they just trying to charge for more wire ? I'm redoing it with 12 gauge it's only for a 600rms alpine amp so 12 gauge i figure is plenty

So I just had a Viper r350 put into my vehicle...I want to add additional sirens. I've seen some 120db ones online for as little as $6... Anyone know if there's a limit to how many I can run off this alarm? I'm thinking 1 in each corner of the vehicle would be nice...

So basically I put the ground wire in the power input and power wire and the ground input, now my amp won't turn on, fuck me. All I wanna know is what did I fuck up or possibly fuck up? Thanks for your help..
