How would I do this?with out fring my pcm and etc?

Which one sounds the best to you? No dvd players or navigation systems... just regular 1/2 din cd players

I have a 1997 jeep wrangler, the stock alt makes about 90amps and idles at 14v without amps connected. If I put a h/o alt 200amp, at idle what would my voltage be without amps connected? I'm assuming its going to vary from one vehicle to another, but stock alt 90amps = 14v idle, so 200amps = 14.5v? 15v? Is there any way for me to estimate the voltage at idle?

This will take over the duties of powering my front stage. The 2100-XXK that's in there right now is doing fine, but the Germaniums seems like it wants a bit more power....so a bit more power they shall get. The 2100-XXK rated at 100 x 2 @ 4 ohm, the 4150-XXK when bridged will do 320 x 2. (Don't think I'll send THAT much power to them though, but it's good to have some headroom) Not sure if I'm going to use this lil guy. If anything I'll just put it on the 1500-XXK that's powering my sub.

i have a 350 A anl fuse less than a foot from my battery. i have noticed in alot of build logs peole have them alot closer to their subs. did i do something wrong or do they have 2 fuses?? Thank you Matt Cusack

I tuned it by ear, but it took a little extra time due to the gain knob being maxed out and still not pushing it's full potential out, so I turned up the bass knob slightly to a point where I saw stress. Now, the sub gets slightly warm after 15 minutes of full tilt, but it's not more then a few degrees higher off the ambient temperature. Just wanting to make sure there's nothing bad going on. Doing the big 3 in days coming, thanks.

I need some advice on how to tune my system. I've got the following...yes they are a bit old but in great condition. Alpine CDA-7844 SoundsStream Rubicon 404 and 702 amps MB Quart 6.5" components with MusiComp crossover MB Quart 2 ways with regular crossover for rear. The 404 is driving the mids/highs and the 702 is hooked up and ready for when I buy a sub. My question is how do I got about figuring out what to set the gains at? Also do I need to set the 404 to high pass and 702 to lowpass? If so, what frequency should I set them each at? The HU has a setting for the "bass control center frequency". I can choose 60, 70, 80 100hz. Default is 100. Not sure if I shou…

I'm wondering what most people use for a good quality front stage. The amp I'm currently using is a TMA T320.4 (JL company). It does the following: 60W x 4 @ 4 ohm 80W x 4 @ 2 ohm 160W x 2 @ 4ohm (bridged) Speakers used in conjunction with: 6.5" CDT Audio ES-620, rated for 150W @ 4ohm I just picked up a SAZ-1000D and a 12" Fi Q and these will be running together. This leaves the TMA to run my front stage solely. I'm worried about bridging the amp because its a pretty cheap amp, and I figure it'll be toast within a year or so if I bridge (if that). Also, the power isn't terribly clean as its a cheap brand amp, though the quality is good (I'm running 60W x 4 out of jus…

What is a good 1/0 ofc wire that is comparable to sky high car audio wire

Where did the gain setting tutorial go? I've searched everywhere and can't find it now. Can someone link me to it plz.

My amp is currently mounted on top of my sub box at the moment. How can I keep the screws (drywall) from coming loose or snapping off? What kind of screws or nuts and bolts do you guys recommend? Eventually I will mount the amp somewhere else but for now that's where it will stay.

I just aquired a DieHard platinum group 35 battery. I also have a kinetic hc600. Would they be safe to run in parallel together?

Hey i was wondering about this amp on ebay http://viewitem.eim.ebay.no/BOSS-AUDIO-PH2600-CAR-AMP-AMPLIFIER-STEREOMONO-1200W/330605297743/item but do i get a aoutput of 1200 watts. i am going to youse it on a duble coil sub 1200w 4 ohms.

Hello, im thinking of getting some new amps for my system, I am really interested in these Crescendo amps, for the price dont seem too bad. I was wondering how the sound quality is on these? My subwoofers are FI q 15, two of them in a sealed box. My mid range speakers are diamond audio hex 6 inch tweeters are Dayton audio R528F-4, 4 ohm silk Alpine cda-117 and pxa-h100, going 2 way active front stage my amps i have right now are 2 ppi pc2600.2 for the front stage and a crunch gp3000.1 pro amp for the subwoofers, i have had the ppi amps for 12 years, realy like them, very clean sounding amps, i was wondering if the crescendo C1100.4 would sound just as good as the ppi? i h…

has anyone ever used them I have 2 of them that rest at 13v and are 210ah a piece just wondering

I have an 18" IA Death Penalty and a Kenwood hu. I am wondering what amps you would recommend for the 18" I also have Kicker KS series speakers amplified on a hifonics zues. basically wondering what amp to get and if facing the subwoofer up or facing it toward the front seats would be better..if I face it up would it be a big noticeable difference. I plan to tune it around 37hz

I just bought an Pioneer AVH-P8400BH and needed advice on which cable to get for iPod/iPhone functionality. The Pioneer website has conflicting information. It says that for App Mode, you need the CD-IU201S but regarding USB iPod/iPhone Direct Control, it says to use the USB interface cable CD-IU201S or CD-IU201V. The "V" states its for iPod/iPhone and the "S" says its for iPod/iPhone 4th generation. More details are below about the two cables. I do have an iPhone 4S and an old iPod.

Hi I'd like some advices to choose a 4ch amp with a budget of 450$ max. Please feel free to make some suggestions. For information, it will be connected to a Focal 165 KRX3. Any feedback on those ?

I'm still not getting the full output of my sub (BL 12), most likely because of low/bad signals from the LOC crudely tapped into the rear speakers at the moment. But I would like to get a new head unit that will give me nice clean signals straight from the head unit. I've narrowed it down to these two (although I'm open for suggestions, like always). I've read on the Steve Meade Forums that this line of the Pioneer head unit was great. But the Kenwood seems very similar. I would like to hear some opinions. http://www.crutchfield.com/s_130P6200BT/Pioneer-DEH-P6200BT.html?tp=5684 http://www.crutchfield.com/s_113KDCX794/Kenwood-Excelon-KDC-X794.html?tp=5684

I would like some input on 5 channel amps from - Polk Audio PA1100.5 PowerBass ASA 1100.5x Infinity KAPPA FIVE Kicker 08ZX700.5 Hifonics ZXi 8010 US AMPS AX 5600 Budget $300.00 to $400.00 My Alpine PDX-5 is clean sounding, just lacking in the thump dept. I sold my old Alpine F353 as it was getting old and I wanted more thump. My system is Alpine 9813 HU, Alpine PDX-5 amp, Polk DB 6.75 components,Polk DB coaxails 4x6 rears, 2-10" Polk MOMO subs @ 2ohm, in a down firing box in a 98 GMC ext cab truck. 120 amp alternator, large conventional battery, 1frad cap, 8 ga power wire.

I'm currently helping a friend purchase the rest of his setup for his Durango. He bought my 12" Cerwin-Vega! Vmax D2 Driver. It is in a 2.5cu ft. box (ported). Memphis Ampl That is the amp he is going to buy. 500RMS at 1 ohm. Class D Question is: Run 4 gauge or 2 gauge? And he has a stock deck, so I will need a LOC, where is a good place to purchase them, and i would need a write up on how to wire one in, along with a source for the remote. Final: Woofersetc is a good site to order from right? I've known quite a few people that have ordered from there without problems

I currently have an mb quart dsc 4125 for 2 peerless sls 8's(does 500 x 2 bridged) sundown 100.4(tang bang mids & alpine tweets) and a sundown 3000 for 2 xcon's. I was doing some measurements in the trunk of my acura tl while laying down deadening and there's no way to fit those 3 amps, 4 cube box, and a big battery so i need smaller footprint amps. what i need is 1 4 channel that can do 300+ bridged @ 4 ohms(pdx is an option, though i'd like something smaller) 1 4 channel that can do 100-125 x 4 @ 4 ohms(may pick up an arc audio mini) 1 mono amp that can do 3000-3300 @ 1 ohm

I noticed Down 4 Sound shop just came out with their own LTO battery. D4S 6 LTO. For 2 of those batteries, it would be rated 6k-10k watts. How would that compare to a 80ah Yinlong LTO bank? Thanks

Going to start a new thread for this, but it kind of piggyback's off my previous battery thread. Got my stereo up and running but was noticing some dimming of the lights both internally and externally. Initially was thinking of just upgrading the battery. I took out my DMM and at the battery it was showing 14.0 and right about 14.0 at the amp (might have been 13.9). So all seemed fine, but then I started to turn it up a bit and was noticing on heavy bass hits it was going down to as low as 12.2v. The gain on the amp is a little under 75% and the HU volume at the time was right around 75%. I'm wanting to turn the gain up more on the amp since it sounds like the sub is s…

Hey everyone, I just bought a used Alpine CDA 9885 and I've connected and soldered all the connections together. When I put it in, it turns on and I can go through any of the functions, but whenever I adjust the volume knob, no sound at all is being produced by my speakers. I cannot pick up any sound through the radio, nor the Ipod function, though it will show that it is playing the track on the Ipod. Anyone have any possible ideas on what could've happened? I have already checked my soldered connections, and they seem solid, so I'm not sure what else it might be. Thanks again!
