I'm looking for a deck that has the same style built in crossover as my CDA-9886 for my girlfriend's car. She likes the built in crossover feature of my deck, but wants something different. Any recommendations?

I have a 1.5 farad capacitor a friend gave me and I'd like to put it to some good use. I have a small mtx amp powering a pair of JL coaxial 5.25" speakers and a punch800.2 bridged for my RE HC 12". I understand some people are against using caps but I have one so I might as well use it. And generally they are used for the amp powering the sub however, in my case I highly doubt it would do anything noticable. So here's my question: What would happen if I hooked up the cap to the MTX amp that is powering the front speakers? Would that give the MTX amp a little extra boost? I believe it's a mtx roadthunder and it's pushing maybe 50rms total.

which amp do i need...i am most likely gonna go with the 2 12" BTL's....Thanks in advance. also wat is the peak powers for the BTL's? and the rms is like 2000??...right?. that sounds pretty damn high! lol ...well that is wat the website said. THANKS!!!!

I know to add up all my amps fuses and the total is my in-line fuse size. My question is about fusing at the db block. I've read in a previous thread on here to fuse under never over( i.e. 180A = 150A). I have an amp (US Amps USA-150) that requires fusing at 75A. It has 2 inputs for positive and 2 inputs for the ground wires. Can I use a 40A + 30A = 70A fuse in my db block or will it affect anything being different sizes and under the fuse rating? Thanks and have a Happy New Year!

just wondering how many runs of 0ga power wire will i need for my system it will be in my 97 expedititon it will have either 4 rockford fosgate amps or 5 sundown amps... fosgate wise 2 2500bds and a 1000.4 and a 400.2 ....and sundown 2 2500ds and 3 125.2s.... batts will be 4 xs power d3100 and a ho 270 amp alt. im only askin sence it has been so long and all my systems till now have never needed more than 1 run of 0ga wire

Hey guys, i've been getting an anoying screeching coming from my component speakers and a deep rumble coming from my sub when ever the car is running, the noise gets louder as the RPM increases. Also when ever you change songs or turn the deck on/off there is a poping sound. I've had my system in for about 3 months now and this JUST started a few days ago. I didn't have this problem at all until now. I have My RCA's run away from the power wires, I also have both amps grounded to the same location. I tryed grounding the RCA's using some spare speaker wire, this gets rid of about 80% of the noise. My deck is a Kenwood KDC-X991 and my amps are a Sundown SAE-1000D and a Sund…

Hey, I was running wires etc today and I decided to just make sure everything worked alright before I got my box built. So the amp turns on and appears to be fine (it isnt in protect mode) but the subs only hiss. It seems like they are moving a little bit but I dont hear any sound except for white noise. My rca's probably arent the best *rockford fosgates* but they should work and for the ground I sanded a patch in the trunk and screwed it down. The amps manual says that white noise is caused by the amps settings but I turned them all in different ways and still nothing. btw I have a hifonics brutus 1606d and 2 12" soundsplinter rlps and a pioneer premier 6700 any ideas?

Sup folks, I have a friend that is trying to figure out a way to make a mini ipod work with his stock cd player. THis is what he is trying to do and figure out. Can you tell me if its possible and if so how do you do it? "I have a 2000 Nissan Xterra SE with the factory head unit (CD/TAPE/CHANGER CONTROLLER DOUBLE DIN) and it doesn't have any inputs on the back other than a 12 pin connector for a cd changer (which I don't have). I'm trying to make an auxillary input out of the cd changer input so I can wire my iPod directly into the reciever for higher quality. In theory this should be possible assuming there is a way to get the reciever to switch over to the cd changer i…

i got a saz-2000 watt amp going to 4 kicker l5 15's, my electrical upgrades are 1 optima yellow top battery 2 runs of 1/0 gauge total 1 pos 1 neg, big 3 upgraded to 1/0 gauge, 200 high out put alt, and 1 die hard platinum p1 in the back, i will be running the amp at 1 ohm, people have told me that i should have much voltage drops others tell me i will, what do u guys think, and i want to get a voltmeter just incase how dou you wire it in

Ok I ran 0 gauge wiring for my saz-2500. I put a 250 amp inline fuse and as soon as I connected the negative terminal the inline fuse blew. So I pulled out the wiring to make sure it wasnt cut went it went through the firewall and disconnected the amp. Ran the wire outside the car without the amp connected and the fuse didn't blow. Connected the amp and the fuse blew once I connected the neg terminal. Faulty amp or am I missing something? Amp was a refurbished purchased from db-r.com. Any ideas I'd appreciate it.

I now run a PPI DCX 1000.1 running 2 IDQv3 subs. A shop in town has had this US amp MD23 sitting on the shelf for a few years now never been used and has marked it way down. Comparing the specs it seems like the US amp would be better for SQ but it is an A/B so the PPI is probably more efficient. PPI S/N 80%, US amp S/N 105%, PPI damping 50, US amp damping 600. I also like the fact that I can run my subs at 2ohms instead of 1 ohm. Anyways this is something I don't have to do but it would be nice to try something new. I don't want the US amp if it's going to drain my electrical system real bad. Any input would be greatly appreciated

Im thinking getting one of these amps. Has anyone had experience with this series?

What type of sealant should I use on my rubber gasket (firewall) that is "temporary" (can be taken off in a couple of years)?

I have a punch 2002, what speakers would work best for that amp. Prefer 12's. I already had a pair of wimpy C4's that crapped out in 2 months, and want something different, but affordable.

Okay, just for fun and to satisfy my curiosity...... In your opinion, what is the best head unit? Best flip up head unit? by best i mean: sound quality (of course), functionality, easy to use, and lastly; curb appeal and looks.

This May sound simple to some but wanted some clarification. I am installing two batteries in my trunk. How they will have to be installed will require me to put about a five foot piece of wire between the positive connections. I will be fusing before first battery where it entered trunk location and fusing after second battery before amp connection. My question is should I install fusing after the first battery and then install a second fuse before it connects to the second battery or will one fuse between them be sufficient?

Wow it looks like nothing came up... So, i'm wanting to get a Sundown SAE-1000D to power my Fi Q10. My sub has dual 1ohm coils. My question is, what will i have to do to keep my amp from burning up if i wire it to .5ohms? If planning big three and a bigger battery. Any ideas? Thanks, Michael

Alright here's my Dilemma, I have two head units an Alpine IdA-x200 and a Kenwood Excelon kdc-x589. I'm trying to determine which one is better. They both have their pros and cons starting with the Alpine. pros: Ipod support, good looking, ease of use, and usb support. Cons: 2v pre-outs, and for the kenwood Pros: 4 volt preouts, sounds great cd support, 2.5mm jack in. cons: no ipod support. I'm trying to determine which one to keep and give the other one to my father. Also i was told by a local shop owner who competed in world finals said that typically CDs tend to get louder than MP3's is this true? here's some more specs. Alpine: # digital media receiver (no built-in…

http://i39.tinypic.com/1z1v76f.jpg Woudld this be the best way to wiring (4) 4ohm subwoofers down to 1 ohm. Or are their any other possibilities.

I measured my GF's CDA-7893's pre-out voltage this morning ... Here are the results. Notes: My multimeter only does AC voltage to 1 decimal point. I only did the subwoofer pre-out, which is rated @ 4 volts. I measured at the end of a 17 foot RCA cable. Battery Voltage = 14.39 volts Subwoofer Volume = +15 (0 dB) All filters off EQ flat No loudness No MX etc. Volume - Voltage 0 - 0.0 1 - 0.0 2 - 0.0 3 - 0.0 4 - 0.0 5 - 0.0 6 - 0.0 7 - 0.0 8 - 0.0 9 - 0.0 10 - 0.0 11 - 0.0 12 - 0.0 13 - 0.0 14 - 0.0 15 - 0.0 16 - 0.0 17 - 0.0 18 - 0.0 19 - 0.1 20 - 0.2 21 - 0.3 22 - 0.4 23 - 0.6 24 - 0.8 25 - 1.0 26 - 1.2 27 - 1.4 …

Does any one know what are some good sites to buy amps online.

I have a Autotek MM1400.1D and Autotek MM75.4 in my truck. I leave my truck parked for a few days at a time at school. The 1400 goes into protect mode when I turn my truck on after its been sitting for a few days (I leave the radio on all the time), but when I turn my radio off then on again everything is okay. I can turn the truck off and on after the amplifier is off of protect, and it turns on like normal. What could be the cause of this?

can a one wire self exciting alt be wired to the same batt as the stock alt ? or can two stock alts run to the same batt ? or would they have to be two seperate power systems ?

I bought a usa-425 from Ryan, the amp looks great and everything, but when hooked up...... nothing. Im thinking its the preouts on my headunit. What is the best way to test this theory out? Besides hooking the amp up to another headunit? Also, if it is the preouts anyone know how these are fixed, if at all? Thanks

hey guys im starting my active build with an alpine 9887 mach5 mli 65 mids and seas neos tweeters im running them off a rockford fosgate p450.4 and i was wondering if anyone who is or has run these speakers can give me a total baseline of what frequencies you were crossing everything over at any information will be greatly apprechiated Brian
