  1. Question about the use of amps crossovers and sound processors. Is it best to go all active not at all or combine?? Are amp filters as good as sound processors? When you buy a component speaker system you are paying for a crossover too. More expensive units have better crossovers. It’s been suggested that these crossovers use up power so not using them and using HPF and LPF on your amps is the better way to go. An alternative method is using a digital active crossover that can be programmed. Different methods are also to influence phase shifts that can create cancellation or have better frequency curves. The cons would be a dedicated amp just for tweeters and one for mids and one for subs so instead of a 4 channel amp driving 4 pairs it would drive the mids on two channels and two channels for the tweeters then not using the expensive crossover that came with the speakers. I’m running everything thru an Audio Control DQX with sub filter crossover point and EQ that is separating the signal at 90hz which I can adjust. Then thru a programmable crossovers The component and coax speakers are all actively crossed between subs and mids but I am using factory crossovers still. I’m assuming they are only helping tweeters but guessing they may have a filter for the mid too? Do you think I am negating phase advantage by leaving factory filters in? Is the phase pollution not disruptive in high frequency so phasing mids and Subs is sufficient? I’m bi amping a pair of JBL competition speakers that has a jumper to remove in the crossover when doing this I am also using amp HPF and running other tweeters off all 4 channels. The JBL owner manual goes into great details about phase shifts and axis to explain what this crossover is doing to help is there a better way to measure it sounds going to me but who knows?
  2. Someone Please Help Me

    Good evening everybody. I have a few items to install for an Audio System upgrade; but don't know how to go about it. The Items that will be involved are -1 Distribution Block -2 Amps. -1 Capacitor. -1 Equalizer/Crossover -6 Speakers in Total (2 tweeters, 2 Front Door 6.5's, and 2 6x9's) -1 Subwoofer I'm trying to connect 2 amps; 1 for the Subwoofer and the Second for Speakers. My Aftermarket Head Unit has 3 pairs of RCA plug-ins. 1) Subwoofer 2) Front 3) Rear. How Would I connect the 6 speakers (which I'm going to rewire) to the 1st amp? Do I wire the Speakers to the Amp or Straight to the Head unit itself? Also, how would I connect the amp to the Head unit if it only has the 3 RCA plug-ins as stated above? Any advice or suggestions are Welcomed. Thanks in advance. URL: https://able2know.org/topic/434961-1

  9. Db Drag Trunk class

    Hey guys, I will be entering Db Drag trunk class this up coming season. Im running into a problem and was looking for advice. In trunk class I will be limited to only two batteries total, 15 volts total and 4k of power total that will be clamped at time of burp. Which sundown amp will be the best fit for me? also I plan on using either 2 nsv3 18's or 4 nsv3 12's at .5 ohms.
  10. I have one positive run to the back. Will that support a 3500d? I have a 3400 with stock under the hood. I am thinking another 3100 in the back. All grounds are to frame to avoid chopping the car up. Thanks for the help its been awhile since I been here.lol

  12. hey i wassup i have a 2000 yukon SLT "profile pic is the truck" on 26's i wanted to do 6 SMD 15'' subs in a clamshell box tuned @ 30hz with 2-3 400a alts and 3 runs of 0 gauge wire with at least 8-12 D3100's from Xs Power batts and a ABVM from Mechman any idea's of what i should do in this bad boy i also though about doing 8-12 SA12s from Sundown audio i want to run at least 18-25krms clean power in this truck so any ideas for subs and amps that will help me achieve this goal?
  13. hey, i have 2 12" sundown SA'12's soon to be 4 or 6 in total. they are all dual 2 ohm subs, i wanted to know if any 1 has any suggestions for a amp that will give at least 2000-2500 RMS @ .5 ohms or 2 ohms and no more than $400 plus shipping. let me know if you have something your selling under these terms and or let me know if you know any amps that are able of doing the job for my system. thanks
  14. i have two 10" pioneer TS-W251R subwoofers in a vented box in my car and right now this kid i know gave me a prehistoric amp for me to use while i look for a new one. (im not even going to say what the old one is... its a joke and doesnt nearly cut it, ill leave it at that) so right now im in the market for a good durable amp that is not going to cost me an arm and a leg cause lets face it, im on a tight budget. so what i do know is the standard stats for my subs they have a norm of 120w and a 600w peak output and they are 4 ohms. what should i be looking at? would something like the Kicker 11DX250.1 be an appropriate option? or should i be looking at a two channel amp instead of that one which is a mono. im not set on any particular brand... just not something thats going to burn a hole in my wallet. thanks for the help! -atokad33
