c.director Posted March 2, 2012 Report Share Posted March 2, 2012 (edited) I bought a truck not to long ago that had 4 JL's in it (don't remember the exact model, but nothing to big..like $150 a pair from sonicelectronix). The problem is that they actually have really good freq. response, they "hit" so low that they distort at fairly low volumes and the highs and mids cant keep up with my subs and defiantly not the subs i'm going to be getting. I don't need them to be hitting 40Hz to 80Hz if my subs are too right? So i'm thinking to fix this I will put them on a 4 channel and either crank up the subsonic filter (it would need to go to maybe around 80hz, anybody know a good 4 channel that has one that high?) or Anybody know a good 4 channel with a HPF that goes down to around 80hz?

Kranny Posted March 2, 2012 Report Share Posted March 2, 2012 (edited) every decent recently made 4 channel and 2 channel have a high pass filter that goes down to like 50hz. brands to look for, fosgate, crescendo, mb quart Edited March 2, 2012 by Kranny Quote Link to comment Share on other sites More sharing options...
LoudBimmer Posted March 2, 2012 Report Share Posted March 2, 2012 Not loud, because you don't an amplifier running to them Quote Link to comment Share on other sites More sharing options...
Onelowgreek Posted March 2, 2012 Report Share Posted March 2, 2012 Do you have a budget you are trying to stay within for a 4 channel amp? Quote Link to comment Share on other sites More sharing options...
c.director Posted March 2, 2012 Author Report Share Posted March 2, 2012 (edited) Probably no more than $250, but looking now I do see most of the good brands can high pass at 80hz.. Shows what gets used around here! I swear the motto is overpay for cheap equipment. Trying to change that haha Edited March 2, 2012 by c.director Quote Facebook: http://www.facebook.com/caleb.arnold.9809 YouTube: http://www.youtube.com/user/CustomAudioChannel?feature=watch Link to comment Share on other sites More sharing options...
c.director Posted March 2, 2012 Author Report Share Posted March 2, 2012 Not loud, because you don't an amplifier running to them I don't think they can handle much more power, they aftermarket deck will distort them long before it reaches its distortion point.

Kranny Posted March 2, 2012 Report Share Posted March 2, 2012 headunits output at the best, around 20w per channel. which is like less than half of what most good coaxial speakers can handle. mb quart has an onyx series amp that does 60w per channel. i think its called the 60.4 or something http://www.sonicelectronix.com/item_23877_MB-Quart-ONX4.60.html Quote Link to comment Share on other sites More sharing options...
corey0928 Posted March 2, 2012 Report Share Posted March 2, 2012 You will find most speakers will sound better for mid range or highs if you cross around 120. Quote Link to comment Share on other sites More sharing options...
neuspeedescort Posted March 2, 2012 Report Share Posted March 2, 2012 You will find most speakers will sound better for mid range or highs if you cross around 120. preach it! not many will dip lower then 100. NEUMAN Quote Link to comment Share on other sites More sharing options...
Amart88 Posted March 2, 2012 Report Share Posted March 2, 2012 (edited) Had the same sort of problem a while back, if your powering them with the HU you need a HPF (high pass filter) Check your HU settings to see if it has one built in? More power would help alot also. Edited March 2, 2012 by Amart88 Quote My 2005 s10 blazer build. 4 zcon 18's walled. Link to comment Share on other sites More sharing options...
