okay some midbass please

akwizeguy · Post by **akwizeguy** » Mon Jul 06, 2009 9:15 pm

Currently, system specs:
Alpine IVA-C800
Alpine DVA-5205
PG zx600ti
PG zx475ti
JL 12w7
MB Quart DSC 215 components

I got the MB quarts in the front doors, and im looking to get something for the rear doors, powered by the PG 475 amp. Im looking to increase the midbass range, cus it seems lacking there so far. What would you guys recommend?

I was looking at the PG RSD65cs, and just not using the tweets, or what about the PG RSD65 coaxial speakers? From reading these phorums, it seems bad to have the tweets in the rear doors right? OR what about those Peerless SLS 6.5?

Any help is greatly appreciated!

In my opinion, I have never been scared of rear stage, whether it be components or coaxial speakers. Though knowing what they are going into would be a great help, and also what are you looking to get out of the stereo. In my old 87 T-Bird I ran MB Reference 3 ways for the front stage, than ran a pair of Fosgate Pro 8's in the rear deck, with 4 JL Audio 10's in the trunk. Powered by an M44 and M50. But my rear seat friends always bitched about the sound quality... which got the statement "Funny, sounds great up here!" But before the 8's went in, I was running a set of AR 6x9's for SQ. You just have to adjust your systems balance to what your ear prefers, if you are not planning on competing that is. The RSD65cs are great speakers, though I would run the whole set and adjust from there.

Though this is solely my opinion, and considering I have been out of stereos for a while, like 15 years, my opinions are from the true PG era. And as the saying goes, Opinions are like assholes.... everyones got one.

hmm., i like the rsd's better then the dsc's!

so personally, i would just go with the rsd comp set and move the mb's to the back

alternatively you could just go with the coax's in the back

the idea of midbass is to have it up front. so adding it to the rear fill would be a waste. any chance you could have dedicated mids up front?

ahh i wish i could have them upfront. I havent ever tried molding a new fitting for another driver in the front. Im only using the factory cutouts. So what setting should i use then on the 475 to get the midbass upfront? Wouldnt that mess with the "vocal clarity" of the music? thanks, sorry for the naive questions!

What kind of car is this? Have you considered kickpanels with a dedicated midbass driver in the door?

Those Quarts have literally no midbass. With a better 5.25" component set up front and lots of sound deadening on the doors, you should have plenty of midbass.

its a 2001 Isuzu Rodeo.
Ive installed all of my components myself thus far. Is it hard to fabricate the kickpanels? Ive seen the tutorials and all, how much would it cost me in terms of materials and such?

Also the quarts dont seem to suit my needs, so do you guys think I should just get the PG Rsd65CS then? Those seems to be the consensus on best bang for the buck then right?
I bought most of my components back in 2001, wish i didnt buy those quarts now. thanks guys for your response and help!

another question, is there anyplace that sells the custom kickpanel enclosure pre-made? Making one is out of the question for me, Im limited because Im in grad school living in the dorms, so I have no tools or workspace to do so myself. thanks guys

kicks are easy if you have the tools...any mid bass you run should be staged in front. The mid bass is there to pull the stage forward so that you can not isolate or pin point the location of the lower bass frequencies. The idea is for a seam-less transition from driver to driver each covering a section of the sound stage.

In addition you really ought to invest in an asymmetrical x over and your band pass channel will run 50 up to 225 range. The most directional of the lower bass freq.

You will need a router, some chop matt...maybe some fleece....tape, foil and a wax or mold break release. If you have the tools it is a weekend job...only trick is forming the mold and thinking through how you are going to mount it...pods on the door of that ought to be really easy....

the discuss mb's arn't too bad...bout equal to the rsd's in sq...imo..a wee bit better but not by much.

q logic makes kick panels and pods and boxes for all sorts of trucks and cars...something that will enable you to get a 6.5 in the kick from them will run you bout 150...take some fabrication to stuff and mount an 8 in one...but it is a foundation.

the discuss are going to do better with more power then I've seen the rsd's do..

Good luck

I think you mean vehicle specific prefabs(maybe) lol custom made means custom made. If you don't have tools or mates with tools who can help then you may need to get a shop to custom build some. Unfortunately its not really viable for a company to make vehicle specific kick panels enclosures, although some make these for sub boxes. as the market is V small and custom making them isnt that hard.

Check Q-froms and see if they make a set for you Rodeo. They cost about $200 a set IIRC. Other then that cost to make your own, find someone w/tools, would be about $30-35.

Locally for me at Home Depot and the local car audio shop
4' x 2' sheet of 1/2"-3/4" MDF wood- $ 9.00
1 sq yd carpet color matched- $ 10.00
1 can of 3M spray glue- $ 5.00
Steel strap, looks like the brace for HU's- $ 5.00
Carpet screws- $ 3.00
Cardboard, local trash dumpster- FREE

1 ) Use the cardboard to make the shape you need down in the kicks in the corner. Use scissors to cut the cardboard.
2 ) Trace that onto the wood and cut it out.
3 ) Cut out the speaker hole.
4 ) Lay the carpet over that to see how much you need and cut.
5 ) Spray both the back side of the carpet and the front side of the wood w/the 3M glue and let set for 1 minute then stretch the carpet over the wood. You'll probably need to spray the back edges of the wood w/glue too to hold the carpet down.
6 ) Cut out the hole in the carpet for the mid.
7 ) Place the kick panel in its place and see how much steel strap you'll need.
8 ) Screw that strap to the back of the kick panel.
9 ) Put kick panel back in its place and screw the strap to the carpet.
10 ) Now put the mid in.
11 ) Reap the rewards.
12 ) Done.

Note that Q-Forms are just a flat panel, not an enclosure. If you get one I recommend you fiberglass the back of it anyways...

There's a very good kickpanel tutorial in the How-To area of the forum.
