Stock Subwoofer

[RXMmazdaspeed]

No worries, I am always glad to help

how much would it be you think to build a custom fiberglass enclosure in the same position as the stock casing with a single JL 10 or 12 and an amp? i like having the space in the back of the car.. and since u are the pro i figured i'd ask

FIberglass isn't descriptive enough.
Is the enclosure to be all glass and have a painted front or is it going to be glass in shape but carpeted?

I think most shops would use a 3/4" MDF back and secure ti to the rear deck, use rings to make the sub mount and then use fleece resin and glass for the shape. How you want it finished will determine the price though.

Hey 1ST. I need some advice.

I have a brand new Alpine MRD-M300 amp. and I had planed to put a JL 8W3v2 D4 in the stock box. Do you think this will be OK?

I am not an audiophile, I just want something that sounds clean and does not take up any more trunk space.

YOur going to give a single JL 8W3v2D4 300 watts rms (wow)????????????!!!!!!!!!!

I LOVE IT

It should sound very good so long as it doesn't need to be terribly loud. A single 8 just insn't going to be earth shaking.

Also, what gauge wire did Mazda use to power the stock AMP?

 

[1sty]

8 for the MSP I believe, it could be 10 though. If its 8 you are ok, if not then yo need atleast 8 for the alpine.

LOL., I suppose I could keep the gain low.

I am not attached to that AMP, its something I had from another project.

Do you have another combo you would suggest? Remember I would like to keep the stock box.


Thanx

what do you guys think about the Visonik products..are they any good, i read a couplle times that they were underrated and are a decent product that is cheap.

That will work just fine.

Decent products that are cheap are those that don't sell through reps then dealers so they don't have huge mark up. Visonik is just cheap, no other way to look at it.

How does the stock sub sound with some good old rock and roll? I've heard some systems that make anything not rap sound like ass. While I like my beats, I usually roll with rock and roll.

I think a lot depends on the enclosure (trunk). My buddy had a system in his Envoy and even at the lowest level possible, the acoustics of the SUV made every type of music WAAYYYYY to bassy (bassy--not really a word but you know what I mean).

Thank you very much sir.

Now I need to go see if Mazda used gauge power wires

Well, since everyone else is asking him questions, I figured I'd go ahead and throw in one.

1st MP3 in NH -- I've had systems in my car pretty much since I started driving. However, my MSP is only the second car I've ever owned. Before it, I had a Dodge Spirit .. which I could happily rip into little pieces while installing audio equipment. It also didn't matter all that much about how pretty things were where I mounted them.

I'm currently sitting next to my system that I pulled out of my Spirit before I sold it, that I'd like to move into the MSP. I haven't gone to talk to the local stereo shop yet about it, so I might as well ask you first!

I have two 12" JL Audio W6v2 subwoofers in a huge -- and I mean HUGE -- custom ported box. I know I'm going to have to have a new box built, because there's no way in hell this box will fit into the MSP's trunk -- not to mention it weighs about 5000 pounds. Any suggestions on box structure?

I also have my old head unit, a Panasonic CQ-DF801U (60Wx4) -- I don't know much about the MSP's stock Kenwood unit, but do you think it'd be worth putting my Panasonic in?

As far as amps go, I was pushing my subs with the JL Audio 500/1 and everything else was powered by a Rockford Fosgate 550X (which had previously been a bad Sony X-Plode amp, but when that blew out three times, I finally learned and got something else). I know I want to keep the JL Audio amp with the subs -- duh -- but should I just use the Kenwood amp that's already in the MSP instead of putting in the Rockford Fosgate? Again, I don't know much about the stock Kenwood amp that's already in there.

Oh, and a random sidenote -- I do have a Lighting Audio 1 Farad Strike Capacitor.

Pretend I just brought my MSP and all those parts into your shop. And tell me just what you'd cook up.

Tear down the stock sub and enclosure.
Have them build you a normaly sized sealed box for your 12's

Put the JL 500/1 under the front seat to make it much harder to steal.

The kenwood amp is only a 2 channel and a unpowerful one at that. Stick to the fosgate if you liked it. I am not a big fan of either one but if you want power to all the speakers form the amp then you need a 4 channel. Personaly I would only power the front speakers and never amp the rears. Leave that to the head unit. Also swap the speakers. You'll thanks me

That was one of the higher up panasonic units If I remember correctly and was certainly a decent peice. Besides its realibility issues and pain in the ass menu system the kenwood is an OK unit. If you liked using you panasonic more, then swap it. It won't just randomly turn off and try to flip only to get stuck and need to be reset, the MSP kenwood radio does this crap alot. I'd use the panasonic.

Hook up your cap with a 4 guage power form the battery and an 4 guage ground. Then split off the needed sizze wires to your amps from it. This way the cap is also a distroblock.

Thanks for the ideas!

I haven't done any speaker shopping in forever .. You have any suggestions on anything new that might've come out recently that would be a good choice? Because yeah, I'm definitely with you on replacing the stock speakers inside. I'm not a fan of their sound. At all.

So far, I haven't had too many problems with Kenwood head unit -- but I've read about all their issues, and it's probably only a matter of time until the stupid thing starts going nuts on me. So I'll probably put in my Panasonic, as I absolutely loved that head unit and the way it conducted the sound.

As far as tearing down the stock Kenwood sub and enclosure .. I haven't really taken the time to see how it's even mounted in there. I know, shame on me. (hand) But I'd like to be able to put both the enclosure and the Kenwood sub back in there someday in case I have to sell the MSP or something like that. Will that be possible to do that if I tear it down?

.. And has anyone thought of putting Dynamat on their MSP yet? Considering how much the paneling rattles from the whimpy 8" Kenwood sub, I'm kinda worried that my MSP will just vibrate to pieces with the two JL 12's in there.

So, what would be a good sub replacement for the Kenwood in the stock enclosure, keeping the stock amp?
