Ok I got a few questions on subs, amps, and components. I currently have 2 pioneer 3ways in the front and a mtx thunder 6000 10" in a bandpass box being pushed by a a mtx 2180(I think) amp.

The sound is decent but its time to upgrade. Heres what I'm thinking of doing: 2 Jl 12w0s 8-ohm, a Jbl 600.1, sealed box 1.5 cubic feet each sub, 2 1" soft dome vifa tweets, 2 5.25 or 6.5 peerless(sp?) mids (thanks cthomp), and an amp undecided to power that. I'm still on a budget but I'm trying to get the best possible system I can.

Now comes the questions:

1.My current amp puts out about 280watts rms and it cuts out after about 40 mins of listening, I think is overheating becuase it comes back on in a few minutes but its really annoying and embarrassing. I'd like to use this amp to power the component system, but I cant have my highs and mids cut out. what can I do to fix this? Or should I just get a new amp?

2. My headlights dim from the single 10 do you think I need a cap, or maybe a better ground? Also if I turn my hu(kenwood kdc-x569) all the way up with the car off it shuts down the radio! I dont listen to it that high but it shouldn't be cutting off. Whats up with that?

3. Will I be getting a lot more bass from the 2 JL 12's. I'm kinda concerned on how low the rms is (150each). My single 10 took 250 watts so they are pretty close. Plus the bandpass made the bass pretty loud, but boomy. I'm hoping to get better sq and spl from the 2 12s.

4. How should I go about mounting the components? I've never really worked with drills and wood before so I'm a little hesistant. I was think of going with a 5.25 woofer and making a 6x8 plate with the tweet and woofer in it, so that I could just drop it in. where my pioneers are and throw them in the back. I dont really want to have to drill any holes in my car for the tweet or otherwise. I also need help on wiring the components up, like getting the speaker wire from the amp to the door.

5.How should I do the wiring? I plan on 4ga from the battery to the trunk, then getting a distribution block that can give 4ga to the jbl then 8ga to the amp I use for the components.

6. Are the Jl 12W0s a good choice for subs? I tried to set this up so I could update to two dual 4ohm subs that get 300rms each if need be. I already bought them, but I got em cheap so I should be able to resale them and get all my money back if you think theres something better out there.

Thats all for now any help would be appreciated
