question with my set up/what would you use

[kg1961]

I plan on using my zx850ti amp 2 zx600 under one cover
now I have a 20f power core I plan on using.
The first amp Bridged will power my 12w6v2 in a sealed spec box.
The second amp stereo will power my 2 -8" sws earth quake shallow subs under my seat in the stock speaker holes.
should I use my bass cube on a sealed box? should I use my ax204 or 406a to limit what the 8" sub can do say 80-140hz
should I just forget the extra xover and run them 120 -140 hz down.
I have the pg tld66 line driver, audio control line driver and a pld1.
I know the zx600 like 4-8 volts.
I have a 215x and a ti30 eq but I don't think I will need it as Im just using this set up for extra bass
Im going to use my TDD5.
any one have some ideas what I should or should not use. I like the highs in the car but the lower end sound like mid bass at best.
When I had a orion hcca 10 in a ported box running off a jl audio 500/1 the low end was great but I was missing around 80-130hz this is why I got new seat subs.
Any info would be great

Keep it simple... two comp sets and a sub is all you really need

At most, run some rear fill off of your headunit that you can fade out when there's nobody in the back.

I am going to use my speaker level to rca to my pld-1 and than to my Eq215x
run the high 80 to 140 off one side on my 850i -600.2 x 2
and the other side 80hz and down off my jl 12w6v2


I have not followed the ti series at all do they make a PLD-1 and Eq215x ti colored??????? if so do you want to sell it?

[stipud]

They do indeed have a Ti EQ215IX, and a Ti EQ30 as well! Not sure about the PLD, but there was a basscube in Ti finish as well. I think the finish of the PLD is moot anyways, because they should be installed back in your dash where they wouldn't be seen anyways.

I don't know if I want to use my bass cube I don't see a point? Its in a spec jl box sealed. I will just use the lpl on the amp if I need to turn it up
as for the pdl1 my car amp is in the rear 11" form it . the deck is a digital cable to my facotry amp
