OK, here's some more pics.

This is where the factory subs are located

The factory sub in it's enclosure

The sub fires down into the enclosure and is ported into the body of the car

After removing the factory sub, I made a mounting plate for the Focal 6.5" woofer

Pic of the Hertz ES250

The amp goes under the boot floor in the storage bin. I still need to mount it and neaten up the wiring

This is the space where the Focal woofers are mounted - under the front seats

The wiring for the mid and tweeter into the doors

I still have a few pics to upload. The door cards are not on properly and I'm experimenting with the tweeter positions. So far they sound best playing on axis.

Looking great Mike.

Can't wait to hear it.

Can I test for whatever I want,CCA,Pink noise test,white noise test Creoss FFT and Alto Mobile RSA31 and LMS,phasing,RTA score on your headunit then your amps,Iasys test to see driver alignment and what notes gets to your ear in phase,out of phase and which ones cansell themselfs out. oh and lastly can your system play music? - you make the oom happy

Just pulling your leg :lol:

you should know the oom by now, I see the dB thing is taken serios by others - why I dont know. the only dB reading I am interested in is the reading playing 30 hz down.

I am looking forward too listen to it,I am sure it will sound nice,just like your other car did

Did you test the frequency respopnce of that sub on a box desighn program in the lower note region,what size box does it require?

by **mikeb** » Tue Oct 21, 2008 8:42 am

lol

Oom I would welcome the input from all of those tests...

The sub is in a 0.6cuft enclosure - as per the manual. Luckily it's the same as the RF sub that I had in there. I didn't use any program to work it out - I just followed the instructions :wink:

It sounds nice to me, but I think it lacks in the sub 30hz area... I would love to test my system with an RTA. The tweeters sound a bit bright to me aswell - mostly at high volume. They may just need to be run in a bit. I haven't mounted them properly either. Mid bass is lekka.

Thanks maxxis - you can listen with pleasure at our next get together.

by **maxxis2112** » Tue Oct 21, 2008 8:45 am

Give the tweeters and cables about 2 weeks to run in. Sound will change a few times but it will mellow out
