Looking for inexpensive Kinetik contenders. Sealed lead acid...

I have a new kenwood head unit I'm trying to install. I bought the scosche wiring harness for my toyota tercel at walmart. I ran into a problem, none of the connections on the wiring harness fit into the back of my kenwood cd player. I'm a noob when it comes to this so help me out? Here are some pictures showing the backs of both head units and the factory wires and the scosche wiring harness. The wires that went into the back of the stock head unit The back of the stock one, see the place to insert the plug? My kenwood doesn't have that There is only one place that looks like a harness would go there, but none of them fit Here is the wiring harness IDK WHAT IM DOINGG…

Last weekend I hooked up a Rockford fosgate p400-4 to my jvc kd-r810 and everything was fine untill today. I went to a friends house and it worked fine but on my way back home the sound would just cut in and out when I turned the volume past 10... At first I thought it was my iPod cable but it does the same thing when I play CDs too. Any ideas as to why this is happening?

I was wondering if my Hifonics Brutus BXi 1610D amp can handle 18v? and if so how will it affect its sound and output? I have a 58amp continuous output switching power supply that I just bought to power it in the house, of course i'm not expecting full power, but I was just wondering how well it will handle that voltage and if it is to high the power supply is adjustable. But let me know ok, hopefully it will be better than my 12 volt 16 amp power supply that it is on right now.

I'm running a sundown sae1200v1 at 2ohms running voltage is 14.6 it dips down to 13.7-13.4... I'm running 1/0ga about 5 foot run its cca though all I had for ground was a chunk of 2ga it's about a foot long ran to the frame ... also got a 1/0 ga battery ground to the frame even went to a relay harness for the headlights

i had a t20001bd on my btl for a loooong time but finally sold the amp and the whole charging system but still have the sub im trying to sell, but i bought this kenwood 9102d from a buddy so i could thump while im trying to sell my sub... when i have all the wires connected (and yes it is hooked up perfect this isnt my first time) the power light does NOT come on, but the remote wire has enough voltage and the power wire is good (checked with volt meter)....BUT when i pull out BOTH 30a fuses the red power light comes on for like 3-5 seconds then fades away, but voltage and everything stays the same on the amp...the 4 channel amp i have hooked up next to it off the same ba…

So I'm slowly putting together a small system for my 2005 TrailBlazer, No SPL Comps, just want something thats really loud and sound really good... Would be nice if it threw up some impressive numbers... What I have in hand or on the way already: 2 - sets of Polk Audio MM6501s (got them last week) 1 - SAX-100.4D (just ordered it today) Should be here by Monday, maybe Sooner... No hurry though, need more stuff... 1 - SAZ-2000D (Had it for a few months for the Blazer, was gonna order 3 more for its redo, but I got the TrailBlazer, so I'm doing it 1st, then back to the Blazer) 3 Sets of Scoche RCA (Per Jacobs recomendation) Buncha wire and connecters and such.... Things to…

I've got a question for all of you in-the-know...... Running a couple of old-school Celestion AD15H's in my Tahoe, 'glassed in the rear corners after cutting out the inner rocker panels. Approximately 2.4cu ft each, with a 3"x8 1/2" port. I know these are rated at 600w RMS, but I'm pushing them with a Lightning Audio S4.500.1 at 2 ohms - supposedly putting out 250 watts to each sub, but sounds like it's making way more power than that - I'd guess closer to 400 watts to each sub, if not more. I'm using 4ga wiring from the battery to the amp rack under the Powerbass S-10's firing down betwen the front seats (nice midbass staging! LOL!). Have an old Kenwood KAC744 (40wx4@4…

I got this from the12volt.com---hope it helps.

Hey guys I am hoping one of you guys know what is wrong with my amp.. It is a older model rockford t1000 and it worked fine a few weeks ago, my sub stopped playing and I assumed I blew the sub and I found out I did. Well I find out that the amp won't power up or anything.. It popped the 150amp fuse on the amp itself and then I replaced that fuse and it popped the in-line fuse to my 4awg power cable. Soooooo I replaced that fuse and when the amp turns on it makes a very high pitched squealing sound and then pops a fuse.. There is a loose rattling on the inside but it has been that way and worked fine since I have had it even though it rattles on the inside. Should I take i…

I have a pretty basic question. I am looking to upgrade the amps I have to Sundown amps. I need to know if the current wiring will be enough and if not what I need to upgrade. I am having a authorized dealer install these so I just need to know what I need to tell them. I have the following gear: Car: 2001 Jetta GL 2.0liter 4 cylinder Headunit: Kenwood KDC-MP438U (3 sets pre-outs) Fronts: Polk Audio db6501 component speaker (max of 125 watts continuous), door mounted Rear: Polk Audio db6501 component speaker (max of 125 watts continuous), door mounted Sub: 10" Treo TE dual 4 ohm sub (500 watt max), mounted in a Ported ProBox Wiring: 4 gauge Memphis 2 amp wiring kit I a…

Ive been searching around for a new headunit for while now. I've narrowed it down to either an alpine cda 105 or kenwood kdc-x494. I've had alpine before and never had any issues. Never owned a kenwood hu before and the only complaints I'm seeing are that they are complicated. And only difference I'm seeing between the two is preout voltage and where the usb is. Which one would you guys recommend and why? Open to other suggestions, except pioneer(bad experiences) and I'd like to keep it around $150.

i'm curious as to weather this amp would be safe to run at in a one ohm setup. the seller... of course says it is. but i'm not to sure

Anyone wanna share any experiences using this. I am thinking about getting it. I seen it in action but since its not actually mine i haven't gotten the full experience of it. Is it worth getting? http://www.soundsolutionsaudio.com/zencart...;products_id=35

So I hook up the Alpine to test the Pre-outs today and upon powering it up, the face will not open,or angle at all. I press the buttons and it seems like the mechanism is either stuck or not catching. Anyone have this problem before or know how to remedy it?

im so confused! so is a bass remote bad to use if you want ur subwoofer to be "quiet?" i know i know Who would ever want their sub to be quiet but im just wondering. ive heard it can hurt the amp/sub or it cant, i neeed answers!!

Looking for an amp to power my soon-to-come SS RL-p12. I found a Digital Audio amp that didn't look too bad. Just wondering if anyone has/had any experience with them. The key thing here is I also need a two channel (75 x 2 - 100 x 2) that matches. (I found a 75 x 2 Digital Audio also.) I am also leaning towards the Directed 750d and 300/2.

Hi Guys, I just installed my front stage a few days ago and now I have a nice problem. The amp I am using for my frontstage is a Memphis 16-ST300. When I'm on the road, it happens really often that the front stage stops for a second or two and then it gets back. During this time, the sub amp which is a Memphis 16-ST1000D doesn't even stops. I just don't know what to do right now. Thanks, Maxime

Ok, I have decided the XXX, huge amp, heavy optima yellow top 31 series, and massive box is too much for what I need it for. I am selling everything except the Rainbows and my HU to Jamie's cousin. Here is what the next system will be: 2 RL-i 8's sealed in a movable box Rainbows on a 150x2 amp (that seems to be the most power they can take) A matching amp for the rl-i's (around 700 watts) Audiocontrol EQT's and 4XS I would also like to be able to stay in the running for USACi 0-600 sq class. I can get the JBL's for about 550-600 if my eBay powerseller pricematch goes through on SD. I can get the Kickers for around 750-800 I think. I already have a PA VX3002, and anoth…

Ok so im anticipating the arrival of my SP4 18" and i figured i get everything sorted out for when it arrives... My car is currently running the big 3 with 0gauge wire, 2 1000ca batteries, and factory 120amp alt. The amp im using is a hifonics zeus 3216 (3200@1ohm) and will be temporary until i can get a better amp. Will my electrical be good enough? Do i need to upgrade alt for 3k watts? Or can i just upgrade to 2 xs d3100s? Also what amps would u suggest that could give the sp4 the power it needs to do its job? Ive looked into the crescendo 3.5, dc audio 3.5,and soundqubed 4.5, any other suggestions and recommendations? ?

i still got my fi bl 15" sitting in my room waiting to be installed into my 04 chevy colorado. my box is 3.9 ft^3 tuned @ 32 hz. i finally decided to go with sundown amps over rockford because i can get them cheaper. but i cant decide between the saz1500 or the sae1200. i can get the saz1500 $570 and the sae1200 for $350. i talked to jacob (sundown audio owner) and he said that the saz1500 is actually 1800 at 1 ohm and the sae1200 is actually 1500 at 1 ohm. will the bl be able to handle the saz1500? or should i just stick with the sae1200...plus its cheaper . im actually leaning towards the saz1500 but im afraid that it will be too much for my bl since im gonna be playin…

I have a AQ2200.1D amp at 1 ohm with my 12" ascendant mayhem, it pounds off stock battery bit I hit the clipping light at around 20 on my alpine cde-hd137bt. I do have a 270 amp HO alt and big three and my lights dim sometimes but I'm wondering what all batteries do I all need to make it bump harder, louder and deeper, and make my stiff rear view mirror fall off?

So... I got bored today and decided to write up equations for amplifiers, like loss, power with efficiency, how to find how efficient it is. basically, a variation of ohms law. as we all know, (V)olts * (A)mps equals (P)ower (V*A=P) but, in amplifier circuitry, this cant be used because amps have their own loss. so lets say our imaginary amplifier is 160A, running off 10.65 Vs, and has an effieciency of 77%. it'll push out around 1312.08 Watts. now to find each number, we use these numbers to find them. Basically, 1312.08W / 10.65V = 123.2a - 160a = 36.8 amps of current lost in the amplifier, 36.8 / 160 = .23, subtract that from 1 and we get .77. simple. I'm quite sure al…

Okay so maybe this is a stupid question just because the amount of power should be fairly close to one another. But I have 2, 15in zcon d2. And im going to buy a new amp,next week. I was thinking of cresendo 5500 and running it at .5 ohms like i am now. But somebody local to me is selling 2 svc 3000. If i strap them ill be doing 6k at 2 ohms. Or my origin plan of crezenxo amp which is rated for 5850 @1ohm. Since im running that at .5ohms not,sure how much ill actually be getting theres no spec on .5 ohm. So my question is which way would be better or does it not matter since theyll be pretty,close? Is this just going to be what brand i choose to run or is there more pro…

have an ms8 going to this amps with epcc engine whine....swapped different outputs form the ms=8 and realized the ground noise is only present int he front rca's of the vlx-4150 no matter the source of output from the ms-8 if i plug in the rears only no engine noise...could this be a defective amp?
