I think my car audio break through was just broken up...lol No, im hanging on the best i can with you guys. I really appreciate the lessons, thank you. Im sure that there are others reading this that are in the same boat as me but were afraid to ask such remedial questions. So if i set the amps crossover to 150, and set the amp filter to "LP", the speaker will play 150Hz down to 30Hz? And if i set the amp filter to "HP", then the speaker will see 150Hz up to 3.5Khz? And to keep my midbass in a certian range like say 150-250Hz , id need to include a "band pass crossover" also? Am i interpeting this correctly, or at least in the same ballpark?

Aaahh OK, Thats what i believed them to do but wasnt sure. Thank you for explaining that. Does same go for mid-range & mid-bass levels too? I mean what keeps a midbass driver set at say "130Hz" from running the low sub frequencys like 30Hz that could damage them?

Thanks a Million "Cant get enough"!!!! That is just what i needed to get a better understanding, It cleared up so much for me. So when someone says "cross those over at 120-150Hz", i turn the knob back & forth between those numbers only, right? So when you set a speaker at a certian crossover number, say 120HZ, does it only allow frequencys from 120 and below only? Or 120 and up? Or does it only allow the frequencys at 120 to pass? Sorry for so many questions at once, but ive had a car audio break through lol. Thank you again!

Thank you "cant get enough". After reading countless posts on this stuff for the past 3 weeks i can almost understand everything you said. lol. I have my subs at the 250 number on my amp because thats where it sounded good. Im still trying to fully understand the Hz numbers related to what effect it has. Thank you for explaining that midbass is between 120-150 Hz. Ive been told midbass is between 60 - 500Htz before, which i thought was kinda big gap. Is there a chart somewhere that i can see that shows what the Hz ranges are for each type of sound? (highs-mids-midbass-sub) That would help me alot., because all i do now is switch the button on the amp to"HP,AP, or LP" depending on the speaker and then turn the crossover knob till it sounds good. On your T1652-S, did you use the crossover that came with them? All i did was wire the supplied crossover in line and set the amp to "all pass". I also have mine in the door IB , with no dynamat yet. You think thats a possible problem? I really appreciate the advice.

@ Impious Thats very interesting. Not to hijack my own thread (if thats possible, lol) does the same theory apply to sub bass as well? If yes, then my system must be totally screwd up because when sitting in the front seats of my crew cab, its obvious the bass sound is comming from the rear. Is that due in part to the large cabin space ,or is my imaging off that bad? Could this be why i crave midbass so bad?

Sure no problem. Thanks alot guys, i really appreciate all the help with this. Head Unit: JVC KW-XG700, with 3band eq and a sub setting. Im currently shopping to an upgraded deck like Alpine,Kenwood or Pioneer. Components Front&Rear: Fosgate Power T1652-S {100rms} - Powerd by an Infinity Reference 475A {75rms X4} (soon to be replaced by a Fosgate Power T600-4 @100rmsX4) The speakers are crossed over with the supplied crossover box, i honestly dont know what frequency that is. The front set are in the factory door locations with the tweeters in the door "A"wing panel-on axis. The rear set is in the rear quarter panel stock locations, with the tweeter next to the 6.5" faceing forwards. Subs: Two Fosgate Punch P2 10" 4ohm single voice coil (due to shallow depth) wired parallel - Powered by a Fosgate Punch 600.1bd mono block. Subs are behind the rear bench seat in a very sealed box 3/4"mdf built to Fosgates specs. I have the crossover on the amp turned to "250" because any lower makes the gap even more obvious. Misc. Info: I have not yet deadened the doors. I was going to during the door pod build. I added a line driver because the JVC pre amp was'nt putting out enough power, i had to trun the gains all the way up. I also had to add 2 ground loop isolators, even after moving patch cables far away from power wires. What my system is missing is midbass, there is a distinct gap between the mids & sub bass. Its the bass that you can hear from a good pair of properly installed 6x9's- if that makes sense? Deep vocals, bass drum kick? My hope is to make some front door pods and install some 8" midbass drivers (along with the 6.5" mids, sealed pod if needed) I can also get a nice 2 channel amp to power them off the split front channel or mono? If it does the trick ill get two more and put them in the back doors too, with a 4 channel amp. Either way, sitting up front in a crew cab you can hear the gap (or void) better than in the back closer to the subs. Or am i just crazy?? Does this information help? Again thank you guys for the replies...

Sure, its a 2004 Ford F250 Superduty Crew Cab. I currently have Fosgate Power components with a 4 channel amp, and Two Fosgate 10' subs with a 600 watt momo block. Im considering adding another 2 channel amp to power two 8" midbass drivers in the front doors to fill in the noticable gap between the mids & subs. Since Fosgate doesnt make midbass drivers, ive been considering JL ZR800's. But ive seen alot of threads where people are using brands ive nevr heard of, nor know where to find them. Brands like "Peerless, CDT, Anarchy, Seas". They all have different capabilities, but how do they compare to a JL Audio ZR800? Because the price difference in these other brands is too good to pass up. Thank you
