Nismo audio upgrade- critique my planned setup

rockhounds

First, thanks for your advices. I noticed that you suggested a JL Audio 600HD 4-channel to power up the Focal's midbass but I didn't see any recommendation for the subwoofer. I'm going on the same direction since I'm looking for SQ and JL looks to be the best shot. The only thing is that I think I'd get the 12W6V2 and I need an Amp for it... I think 1000 1v2 is too much and I need to know if the JL 500 1v2 is enough. Having this set up, should I need to trim or adjust anything on the doors? Do you think that the factory enclosure from JL is the best option to go?

PS - My head unit is an Avic Z110BT.

Thanks a lot!

the JL 500.1 is perfect for the 12W6v2. That is an excellent subwoofer! A 1000 watts is just too much! If you havent bought an amp yet, I highly recommend the JL HD 900/5 amp. It will power your whole system very nicely.

I wouldnt drop the dough on a JL enclosure though, the ones from Zenclosures are very good and very reasonable.

You will need some spacers for your fronts but I think you can also get them from Zenclosures too and they do not cost much.

Nazar makes a nice eclosure for the 13Tw5 but I will tell you right now that the 12W6v2 is a much better sounding subwoofer. The 13Tw5 is louder but lacks the finess of the w6 series.

Thanks again buddy. I didn't buy the amp yet but are you sure the HD 900/5 will pull a 100% out of the potential on the sub or would be better to get a 10"? I mean, the sub channel has only 500 W... and the other 4 x 75 W... I heard something about those specs being not in RMS but I'm really not sure.
Also the factory battery is enough to power everything up?

Oh yeah, it definitly will! The 12W6V2 is rated to 400wrms so throwing 500 wrms on it will push it to its limits. The 900/5 is 500wrmsX1 and 100wrmsX4 and if you bridge the front and rear channels you will have 150wrmsx2 which is where you want to be when pushing a high-end 2-way or even 3-way component system.

I do recommend replacing the battery with a dry cell type battery. They are a big step above the lead/acid spiral cell battery and like 5 steps above an OEM nissan battery. Oddessye and Stinger are the only ones I know of. Your stock battery wont last long with an HD900/5 sucking on it. 1 year max!!

Thanks a lot guys. My understanding is that the 12W6v2 goes up to 600WRMS so I'm actually delivering 100WRMS with the 900/5 right? About the 4x100WRMS, how would be the best way to hook it up to the Focal Polyglass 165 VR 6.5-Inch 2-Way? Also, do you recommend the JL factory enclosure for the SW?

I run my 12W6v2 in my Armada with a Alpine MRV-605 and its a tad too much. Anywhere between 350wrms and 450wrms is the sweet spot for this sub. A little more wont hurt as long as you are conservative witht he gains. I would bridge the front and rear channels and drive them at 150wrms. The Focals will take it as long as your crossover isnt too low and be conservative with the gains.

What i really like about the JL HD amps is the lack of bassboost or any equalization. It does not alter sound that is coming in, just pure amplication. I feel that bass equilization just colors the sound and only makes the amp work harder and start producing distortion a lot quicker. I feel the optional bass knob for this amp is very usefull.

If money is no object, then hell yes I recommend the JL enclosure. Otherwise similar results can be had for much less.

Awesome! Thanks again 2 fast... I think this setup will reach great results. Next problem is to find a good installer because I will not do it by myself.

Take care and I will post my feedback after getting everything done.
