well, im wanting to put a good system together, just to start out with. its goin in a 2000 ford explorer. i dont wanna spend a s*** load of money, but wanting something strong. ive been lookin and reading quite a bit and have read pretty good stuff about pioneer, alpine. one of my buddies is really good at all this, and he said 1 12in type-r 2ohm, hifonics brutus bxi608 amp and a custom box he can build me would be about perfect. he suggested kenwood or alpine for the hu, and liked the KDC-338 the best since i need iPod hookup. tell me what you guys think of this, and what you might suggest instead. thanks!
Your "friend" was doing so well until the head units. Kenwood makes decent HU's, but for the most part, the good quality lies in Alpine, with Pioneer in close second (only problem with Pioneer is the micro-resistor that's attached to their pre-outs that's really touchy... if the resistor blows, you get engine whine and it's just bobo.)
There are a few really high-end brands... but, for $220, you can get a Pioneer DEH-P6900UB. I have this unit, and it rox0rz my sockz. For $300, you can either pick up an Alpine 9887 [A lot of members use this unit] or a Pioneer DEH-800MP, which is the equivalent.
But a single or double 12" Type AARRRGGHH should be good enough. This would focus more on shear loudness over sound quality, though I hear the Type AAARRGGHHHS don't sound too bad if the enclosure is built properly and the signal isn't clipped.
Not sure of the price on the Type AAARGGGH's, but some other options are Fi SSD, I believe some lower DD lines are really good, IDQ's are supposed to be good, and are decently cheap... but if you want to focus more on quality, people have suggested the Fi Q, IDMAX (IDQ's are supposed to be good, too), or the Alpine Type X (Although, I hear they aren't that loud.)
The Fi Q 12" sells for $290 with the BP Option [allows more power handling, IIRC], the IDMAX sells for 400, while the Type X sells for 400, these are all new. You could buy a used one for a lot cheaper.
