I have a 2004 Tahoe and my rear air works but blows cool air only, no heat. Any ideas what could be wrong anyone?

Ok speaking in general about your set up. In the rear you have 18" sub 70hz and 6.5" starting at 60hz. You can pretty much forget about hearing your rear mids from 60hz-80hz because they are competing with an 18 at full RMS power. Now if you start your freq for mids at 70hz you need to up your mid power across the board. You will need more power and cone area (add'l 6.5s) to hear an audible difference in the mid bass. May even want to look to 8" subs in a small enclosure for this. If money is an issue I would move the mids up front and concentrate on your front stage only until you can dump some cash into it. Plus even though your sub is a Q you may want to consider downsizing if you aim is to achieve solid SQ. Don’t know what else to tell you but unfortunately you can’t fix your problems without cash. For instance I have 2 18’s with 1200w per sub and I have 6-6.5 and 6-1” tweets. I still need more balance.

80hz is fine for a freq response general start point but you need to first look up the CTX model and check the freq response zone of the speakers. Many mids don’t start at 80hz and may start response around 100hz. Even though I think you have other issues more pressing, if your mids were not designed to recreate a freq that low you may be out of luck having your current mids sound the way you want them to. What type of vehicle is this set up in? Is the sub in the same airspace as your mids? (all in the cabin or sub in the trunk?) What is the cut off freq of your sub? You said it is tuned low but how low are we talking?(not box tuning but crossover wise) How are you crossing the mids over? Amp high pass? What are your settings adjusted to? Other than my questions keep in mind that you have only 2- 6.5's competing with an 18 on your human ears. Sounds properties make perfect sense but almost all studies have been recorded in controlled environments (ideal space, temp, constant controlled power etc) and don’t always work in theory inside a terrible acoustical environment. (all cars) Have you listened to the mids with the sub off? If so, are they responding to the midbass freq or just sound like shit on the good midbass notes? If they sound good you may need additional mids to achieve a complete sound.

Man those Cerwin Strokers look pretty nasty. Thor did you get to hear those?

Product I'm looking for: DC Lvl4 18. (Blown or Functional) Condition: Flexible. Can be in need of recone or functional. Functional and damaged is fine let me know. Time Frame: Immediate if you have what I want. PM me and we can discuss.

I file once on your PC needs to be converted by itunes into the proper format. If you drag the file into itunes, then from there you should have the covert option in your files options. It will take awhile for a movie.

Everyone just needs to make sure that :censored: Hank Character is off the damn Christmas lists. I don't even want to know what Hank got hooked up with if he is mentioned by name for the backlog of used amps!

My buddy has Sundown and I'm trying to find reasons to get something different so we don't have the same 3500 but damn..Once again I feel like an idiot for even considering anything different. Hands down Sundown willing to go above and beyond really understands CS and gives a shit . Nice job guys and thanks for posting another example k3n12ock!

Dude that is sick!! Way to think HUGE!! Can't wait to see vids!

Thorshammer has a PHD in this kind of question, but just as an FYI I clamped at 1200w per sub on my 18's lvl4 5coils and they sound kick ass!

I'm the same way about actually getting my ass in the theater. Trust me man you will be just blown away.

Alright I just seen Avatar in IMAX 3D and it was flat out memorizing. Hands down the most amazing thing I have ever seen. Totally speechless considering I can still remember being jawdropped by Terminator 2 In the theater. Bros if you can see this movie on IMAX in 3D pay the extra money!!

X2!!!!

Rusty is the man!! Congrats

Dude listen..900 RMS at 4ohms and the phrase "not break the bank" don't fall in the same sentence. May be cheaper to just buy another sub and start over.
