ok so i got the fosgate hx2 15 instead of a sundown z15 because the guy lowered the price to $150 it was BNIB. so i built a box tuned at 30 hz put it in my backseat playing with the placement. its only ran on a bazooka 500w mono P.O.S on a busted ass pioneer deh-p3500.in a 76 caprice btw, well anyway at the first of march im gettin some money and im gonna get either hifonics bxi or a audiopipe 1500....ok well im looking into a new head unit im looking for something around $150-$200 with 4-5v pre outs any recomendations?and maybe a pair of 10's or 12's so the hx2 isnt lonely.......or sundown 8's just looking for ideas and you guys have been alot of help so far

pics up tomorrow

You want to run another size woofer with the 15"? No.

yeah wanna add more with another amp

Don't do it.

that wont work. i think its because of cancellation issues with different waves from different size woofers. either get another hx2 or sell it and get 2 of something else.

Ya, big no to two different sized woofers. and if you want a good deck for cheap, in my opinion you can get a cheaper kenwood excelon deck. Some of there models are a little overpriced but if you dig around you can find a good deal, I have one and I love it. I have there best model though, but still nice clear sound is in all there excelon models. Here is a link to a good deck..

You don't have to focus on pre-out voltage for the h u. YOu just need to set the gain correctly : it's made for that!

Adding another size of woofers is a not a good idea! Cancellation will be a problem! If you're looking for more why not try tuning a little higher like around 35hz.

As others stated, terrible idea to just add another woofer. You have to replace what you have, not add to it.

Also, you don't need 4-5V outputs, not at all what I'd recommend looking for spec wise when digging for a head unit.

A more general budget and goals would get you a lot further to meeting what you want.
