Here is what I have now, give me some ideas

2004 Hundai Sonata

PYLE PLD51MUBT HU.....4x80

TMI 600:1 running at 2ohm load (I think)

2 each Directed Xtreme 12"-4 ohm running in parallel to the TMI mono amp (really don't know how to tell if they are DVC)

1 each  door Pioneer 6.5 -4way in front doors

1 each door 1" titanium dome (factory) tweeters in front doors

I have the right side door and tweeter running parallel to 1 channel from the deck (same with left) that takes care of 2 channels)

rear deck has 2 factory 6x9 that run off 1 channel each from the deck (I have Pionner 6x9-5way to replace these but the job is extensive tear down so I am waiting till fall (I live in AZ) (that takes care of the other 2 channels)

It sounds great to unexperienced ears I guess, but would probably hate what an expert would have to say about it.

So I guess I really don't have the mids and what is running from the deck on a crossover,  the back 6x9's can get a little "boingee" so I need to figure out how to do that without having to buy another amp (no funds right now)

Any suggestions or  ideas are appreciated
