Check out newbie's $800 system

Alpine CDA9820XM head unit

Sony Xplod XSW1621 6.5" in front

Pioneer TS-A6870R 6"X8" in rear

Alpine MRP F240 360 watt 4 channel amp for front four speakers

Kenwood KFC-W3009 12" sub in single BLACK/ chrome bandpass box

Kenwood KAC5201 250 watt amp to drive the sub

(2) 8 gauge kits to wire amps

Alarm with remote start, keyless entry and LCD pager remote

I spent about $800 on everything.  All parts are brand new. 

All wiring either soldered or tightly crimped, and covered with heat shrink.

I have to finish installation this week, so far the head unit and front speakers are in.

It is going into a 1990 full sized Ford Bronco.  I am also going to Dynamat the front four speakers.

I will let you know how it sounds when done!

Thanks.  And sorry about your friend.

Yeah, I shopped carefully.  none of the stuff is "warm" in any way! 

Ebay is very helpful, if you are careful. 

And I got the Kenwood amp for free when I bought the head unit at Car Toys.

Putting it all in is a PITA but it is worth it in the end.

No reason, I just wanted to make sure to have enough wire and fuse holders.  I got a good deal on them so I bought two.

Also, my needs do not require a 4 gauge kit, so I figured why hassle with the thick wire if it is not necessary.  In fact I don't even need 8 gauge, but I would rather be a little over than under. 

Huh??  All I gotta say is...it's a good thing you didn't find a good deal on 10 gauge!  8 ga. is bare minimum for your system as long as your running all speakers and sub at 4 ohm impedance.

The other thing is this:  you bought a bandpass box with the sub.  You should think about swtching to a sealed enclosure instead.  Or maybe simple ported.  You've only got 120 watts going to the sub with that amp.  Your enclosure is designed for SPL, but you've got a minimal setup.  You will need to get more frequency range out of your sub than a bandpass will allow.
