Hi folks, joined your forum today after a lengthy break from the audio scene and would like to put an SQ orientated car together with a view to possibly competing. Im a bass monster at heart !!
Its a MK3 golf , most of my audio kit is old skool and was curious if it would still hold up against modern equipment.
I have an alpine cta1505 commander head , nak cd400 , denon 760 , 660 amps , soundstream a10 ref amp , Audiocontrol esp2's , early mbq hq 3 ways and 2 12" strokers.
I understand that the installation of the kit is just as important as the lit itself.
Thanks

it can hold up pretty well, marko's installs tend to be all old skool and do pretty well in competitions.

as you say, the install matters just as much as the kit, but with some care there is no reason why you couldnt be at the pointy end of the competition.

If its car audio - it stays
If its fun - it stays
If its porn - it stays
If its controversial or grief - out it goes....

that's a great kit list, those denon amps are very rare and as good as anything! getting a good solid install with plenty of sound deadening will be a good start :)

Just wanted to know if the kit was still viable and capable of holding its own at competition level.
I will upgrade the 3 way though , have heard the Diamond Hex 3 way - silk tweet and i loved the sound - any others have a similar sound quality ?
Are the ESP2's competition legal ?
Basically just pointers relating to placement of the 3 ways in the car based on experience or previous listening within a mk3 golf.

Thanks
Had the amps from new after upgrading from the DC400 , 500 and 800 , i just love the sound and have never had any issues with them.

I see you are running the dcs sub , i have 1 in the garage with a crap surround and punctured cone , i will see if i can locate as it of no use to me now.
Used to run a full 8 amp 4 sub Range Rover for denon many many moons ago !!
Still got a brand new DCT1000 wrapped up for a rainy day , and a brand new Yamaha Natural sound head too.

Another Denon fan here :love: With regards to building an SQ system, a car with a pretty useless system can sound amazing if properly installed - look at things in great seriousness like deadening, insulation and path lengths. the draw of wonderful all singing all dancing new equipment can be mesmerising, but un-necessary in my opinion.

Some of the old school kit is still very very good, but will still sound rubbish in a poor installation with poor setup.

Hell my home hifi uses 18 year old amps and the turntable is from the 1970's :lol:

Totally agree with the installation quality being of utmost importance.
im not a fan of modern kit or cars for that matter either.
Im a body builder and sprayer by trade so fabrication is my game.
I got to prioritize my projects now !!!
Looks like my old fords will be getting older before i get round to completing them ! :D

The key to SQ in a car is, as Rod said, path lengths...

1. Get the mids/midbass out as far in front of you as possible and as wide as possible. This should be a doddle for you as you do car body work.

2. The next thing is solid mounting for all the speakers - don't use MDF if you can use birch ply, don't use birch ply if you can use steel - I'm sure you get what I'm trying to say. Then,

3. deaden every resonating panel in the car.

4. reduce as many reflective surfaces in direct line of the speakers as possible by either removing them or covering them with a variety of foams / soundmats etc.

I haven't mentioned angling or tuning but this is practically the same as it's always been; a compromise between what you want and what you can get.

I don't know which of either mids or bass speakers in a three-way up front system should have priority on being the furthest from you but in mine, I have put the mids in the kicks, bass in the doors and tweeters where I could best place them / sound good.

I have read a number of times that if you cross your mids up or above the 4k mark, tweeters don't need to be mounted near them and from what I've heard, I would agree with this.

I used to have a Denon DCT1000R, very sweet unit. I bet yours is worth a pretty penny if you were to ever sell it.

Nothing wrong with old equipment infact often its better as it was properly designed and built back then. As others have said its all down to the install and tunning.
