Hi- Does anyone know of some good active crossovers that have bandpass options? All of the ones I've been looking at only do high pass and have a subwoofer output. I really need one that can do a bandpass 50 hz to 2.5 khz, or just a 2.5 khz low pass for my mids. Then a 2.5 khz high pass for the tweeters. Obviously the high pass isn't hard to find but for some reason the low pass is... Any suggestions? Budget is maxed out at around $150. Any other info required just ask and I'll let you know. Thanks!

My bro wants to put a lil somethin in his boat while he is up in alaska. Since he is going to be in salt water, is there such thing as a 4 guage wire that wont corrode from the salt water?

my friend has a 92 ford taurus with a 130 amp alternator and wants to upgrade his system to a audiopipe 15001d is his electrical sufficient enough for that amp or would he need a second battery in the trunk

i have stock electrical, just one 4 gauge run to my alpine pdx 1.600 amp (600rms, 730 peak), but my gauges/instruments dim down to about 50% and my headlights dim terribly. will the big three in 1/0 or 2 gauge solve this problem? i have a 2003 vw passat, im pretty sure my alt does 90 amps..

I Have 2 kicker L7's dual 2 ohms. which amp is a better match? RF 1500 D, mtx 1500, kicker 1500, aq 2200d

Just woundering what's a good eq for my set up plan on running a ipad mini for the headunit...eq? ??, amp is a bc2000, 2 orion hcca 15.2, crescendo 1100.4, 4 pwx 6.4 and 4 Ft1 tweets. What will be a good Eq. I was thing about a audiocontrol three.2...waiting on my most of the items...as well a crescendo battery

I am still waiting on pioneer's avic f90Bt because they have to do a firmware update like 3 or 4 weeks out anyone else dealing with this. I have been waiting for 2 months now, any input on kenwoods DNX 8120 in how it compares Im getting tired of waiting. Should I go with the Kenwood or stick it out for the pioneer?

So I've tried both my HU and Ipod for a source to my amp and wired the amp to 2 different subs at different impedances. Always turns out the same way, some rattling sound coming from the speaker. So Obviously it's the amp because I've tried two of everything else. The "sound" plays with the signal, not with engine RPM, so I know it's not related to my ground. You can hear it at low volume with gain turned up just enough for sound to come out. I think it's also causing my amp to go into protect mode prematurely for some reason because it would go into protect around 30 volts on the DMM when setting with a test tone. Amp is a Hifonics 1505d (explains a lot, I know) left ove…

i yet to get my new head unit, but for when i do waht should i look for on it to makes everything so great, a friend of mine had a system and it sounded good but he got his deck tuned and it sounds 10x better, he can now turn it almost all the way up without any distortion the subs sound more clean and the vocals sound more crips, they never touched his woofers or amps just tuned the head unit, so waht would i look for when i plan on tunning my head unit, Thanks

I took it out a few days ago and it had a 3.2v charge. A few min later it had a 1.2v charge, then 0.0v. Idk why it did this, or what I can do. But it sucks. Thoughts?

what is the best way to set ur amps using lpf, hpf and your subsonic filer. what is the purpose of lpf and hpf. the box that i am using is sealed. the subs that i am running are kicker cvx's (1000 watt rms) and i am using hifoinics amps (2000 watt rms, i know they really rnt) and i run my subs at 1 ohm.

i just got my autotek mean machine 1500 hooked up to my 2 type r 12s and i got the ssf at 35 and the lpf at 80...what do you guys run yours at or suggest i run them at

http://www.crutchfield.com/S-KJi47TPlPGC/p_130AVHP410/Pioneer-AVH-P4100DVD.html obviously doesn't cost $400 through them but I found a few sites that sell it for $400-450

Just got a N1 for free.... Pulled it from a car being scrapped. The owner accidentally chopped the cable to the hidden unit when pulling it out. I looked on ebay but dont feel like waiting anyone know where i can grab one of these in ontario? Ive called around but all the shops are closed and whatnot Blech!!

Waiting for Maxxsonics to return my call with regards to this so while i wait, let's see if any of you know this- OK, we all know the Maxxlink is a processor that can take up to 10 amps and strap them externally as 5 set pairs. This is where i want to make sure i can do this... Instead of strapping mono channel amps together, can u strap amps that have been internally strapped? IE - one board is sold as a 1500w amp @1ohm and another amp has 2 of these boards in it rated at 3000w @2ohm.. Would you know if u set these amps up in bridge mode to form a mono channel if one can safely use a maxxlink and strap a pair of amps like this to 6,000w@4ohm? Also, from what i gather.. i…

I have never wired miltiple amps to one sub, so please bear with me. I have four JL Slash 1000/1v2's and two DP 21" 2 ohm dvc's. My question is; how do I wire two amps to each sub? Someone suggested that I wire each amp to each voice coil. As in wire one amp to one of the terminals on one sub, and another amp to the other on the same sub. Is this correct?

Walking through Target the other day I saw an interesting Pioneer box out of the corner of my eye. Not expecting to see nice head decks or anything really pioneer at target, I checked it out and found they were selling CD-IB100II iPod adapters for $14 a piece! I can't find these for less than $50 online. They had at least one left, so if anyone here needs one cheap, $14 + shipping and I can probably send you one. I love finding deals like this!

well im about to start my new build some time next week hopefully and im trying to get my electrical squarred away this weekend so here it goes. i recently recieved my new amp (cactus 5kw), and i know it is going to need alot of juice so my plan is to 1.) upgrade my starting battery to a decent car audio battery (everstart maxx, walmart style now) 2.) do my big 3 in 0 ga (haven't done that yet) 3.) run 0 ga to the trunk 4.) one battery in the trunk for sure (d3100) and possibly another if i need it. so far my knu koncepts cart looks like this: 2, 0ga amp kits(for the extra wire, 250amp fuses), 4, battery terminals, 2, 200 amp fuse(for alt and rear batt.), 10 foot of 10ga…

I have an aq2200d that will be powering a ss rl-p 18 at 4 ohms. When i go to wire it up, do i use the outside pos and neg ports on the amp? Also, i have a kicker 200.4 for one set of components. I want to bridge the amp to make 100.2 at 4 ohms, but im confused when it comes to wiring it. there are two rows of inputs for speakers. one row says amp 1, and the other says amp 2. would i just do one speaker on one row, then the other on the second row? sorry its confusing. ill try and find a picture. http://www.sonicelectronix.com/pictures.php?id=11366

waht setting do you put your dmm on to check wattage??

Soooo i just got my kicker zx2500.1 and will be running two Fi 15in BL's on it got all the wiring and everything except for the fuses... Any suggestions?

I was wondering if I needed to solder the ends of my power wire(1/0 knuconcepts) before i put it into my amps. Same goes for the speaker wire going to my sub and speakers. Also, can i just get a cheap battery powered soldering iron, or do i have to get a nicer one? thanks.

Explains the pros and cons of caps and also when, where, and why you need an alt and or battery.

I have a Hifonics Brutus 1200 watt mono and a 15" FI BL sub. Any advise on how to get the loudest but still the best quality out of it? it's Level 9v - 0.2v , Phase 0 - 180 , Bass EQ (keeping it down) , Sub Sonic 15 - 35 Hz , Low Pass 35 - 250 Hz.

So I finally got around to openning up the Lightning Audio S1.1000D I had running a couple of AA Assissins and two (that I noticed) of the transisters labeled IRF6215 have gone to amp heaven... I don't see any other problems, is it worth trying to replace the fried parts or will I run into more problems as I progress?
