Not impressed

[hispls 5,000+ posts]

I play almost every thing dead flat on the eq (it was in the vid), so 32 bands are completely unnecessary for me. I'm not a fan of pioneer, but hear nothing but good things about the 80. I would like to have the adjust-ability of the mid range xovers, as well. However, my setup sounds pretty darn good considering i've built it on a fairly meager budget.

You'd probably use 32 band EQ if you had it. I would run EQ again if I had the space, though I must say with good equipment, crossover points, and mounting locations I seem to do pretty well without.

I have been considering a move to the x996, which has 13 bands per side. I just don't think I can make proper use of such a detailed eq without an RTA. I always feel like I'm just guessing, lol, so I leave it flat and adjust it only if there is a glaring problem.

S4 bridged it on the Boston to get 400w at 4ohns setting on the head unit is bass at +6 the sub level is +11 no bass boost

This is a recipe for disaster. Let me tell you that the correct "subwoofer level" setting on the Kenwood decks before you set amplifier gain with DMM is 0dB. I have measured the Kenwood X994 (very similar to X993 through X996) deck voltage on subwoofer RCAs with a DMM. If the signal is at full tilt (0dB signal playing at full volume), then the AC voltage on the outs is close to 4V, as the specs claim, with the subwoofer level at 0. If you increase the subwoofer level, then there is a chance to clip the signal. The DMM tutorial is wrong is suggesting to max the subwoofer level on the head unit before proceeding with setting amplifier gain. This issue must be examined on case by case basis.

Also on the +6dB on sub. This is a great receipt to over drive the amplifier and destroy subwoofer with a clipped signal. Set ALL settings to 0dB (no bass boost, sub level at 0, etc). Then set your gain with DMM. See what happens. Use 0dB test tone if you want to be conservative. Use -5dB tone if you feel adventurous. (I prefer -5dB as normal music hardly ever reaches 0dB, much less continuously).

I don't think the X996 13 bands are per each side. Another problem with these Kenwood decks is that their face plates are not particularly reliable. The Kenwood KIV media players may be better in this respect as they come with non-removable face plate. In any case, the Pioneer DEH-80PRS AutoEQ does seem to do marvels to the sound. The result is very clean sounding midrange with great imaging. Much better than what I could ever get by tinkering with time alignment alone or with EQ manually with no RTA. The only issue is that it set subwoofer level too low for my taste (fixed easily).

Lol, did you happen to read my post regarding this?

I honestly forgot completely about autoeq. That would be nice. And I'm fairly certain it is thirteen per side.

Alright I turned everything thing back down but I'm not getting the same excursion everyone else on YouTube is with more power, also when I turn it up I am hearing something that sounds like rattling but it seems like its coming from the sub, I guess te only way to tell is to pull it out and play it and see why I fucked up.

I have more power is what it meant*

Expecting it to wang off 400 rms sealed hahahahahahaahahahahahaha

 

[Nut Hair Trick 10+ year member]

Yeah, The op didnt do much research before he bought.

Couple of things from what I have read.

 

#1 The Dcon is not broken in yet.

#2 The most logical option for the output desires is to port the Dcon first

#3 Keep in mind this is a 300 rms ratted SQ biased sub woofer, please don't expect Xcon level of output from the Dcon.

 

So once it is ported and broken in, I really feel you will like the output as the performance per dollar ratio of the Dcon is very hard to beat.

Figured out my shittaayy sub box was leaking new one 2.25 ported at 33hz ordered

 

[Nut Hair Trick 10+ year member]

Ordered from whom? It's not a prefab is it?

4 months of searching, asking, talking, on forums, watching vids I put in the amount of thought needed just had a leaky box and when I turned my gain up it was making a buzzing noise and I thought it was at its limit but its not. It was user error, I knew it was that's why I said it wasn't a ssa prob. I know these things get down I just wasn't using it in the correct enclosure

Thanks everybody as soon as I get it in the new box ill update
