questions about HU, amps, subs

Hello, i'm new here, i have a 1998 honda accord ex-v6 coupe and i recently purchased a Pioneer DEH-7500MP (from reading through the forum i noticed virtually everyone prefers alpine head units but i just think the pioneer is a better looking unit (a concern for me)).  I also purchased 2 12" MTX Thunder 6000 T6124A 4-ohm subs for $179.99 from crutchfield (i thought it was a good deal for decent subs they were originally 140 apiece).  I currently have a sealed enclosure with 2 12" blaupunkt 250rms(extremely beat up thats why i'm replacing)  with a mtx thunder 275x amp.  Everything else is factory.  my first question is am i making a mistake by going with the pioneer hu instead of something else? my second question is the quality of the MTX subs ($180 was about what i wanted to spend for the two), lastly should i upgrade to a new amplifier..could i use the old one to power other speakers if i did upgrade.  any suggestions for front and rear speakers would be helpful as well.  sorry in advance if i asked to many questions.  thanks

ps (i'm not looking for mind blowing sound, i just want decent bass that i can enjoy (not the rest of the neighborhood)

If the amp was bridged to output 500 watts rms for the blaupunkts then make sure it 4 ohm 2 channel power rating isnt to high for your speakers if you use it for your speakers. Again ,if you tell me the specs of your amp right now I could help you better. Also the MTX are fine subs. Not as good as some brands but not bad either.

i looked at the amplifier to try and get more specific specs but i could not find anything offhand.  The amp just says MTX Thunder 275W, the box and amp are not currently installed because i took it out of my 99 Jeep Grand Cherokee before i sold it.  i think i am going to stick with the same amp for now to see how it sounds before i decide to spend any more money on an upgrade.  How can i get the most out of it? (before i install it, local shop will be doing it but i want to make sure they do a good job)   thanks

Sorry i was just guessing the output of your amp since you said your blaupunkt subs like 250 watts continuous (RMS). Does your amp say it outputs 275 watts X 2 channels continuous or does it just say 275 watt max? If it does say it outputs 275 watts continous X 2 channels then is it in 4 ohms or 2 ohms or is a max power rating (maximum power at a musical peak)?

Ok i looked around more and found out that your MTX amp when bridged only outputs 150 watts which really is barely enough for one sub. Even if you dont want wake up the neighbors bass you should still get a bigger amp then this for two subs. These subs like around 180 to 250 watts continuous. I would reccomend the Rockford Fosgate Power 350M. It outputs 350 watts continuous in 2 ohms which is about perfect for your subs. If you order it from Crutchfield then its only $199 so you save about $75 on a great amp. Since that amp was pretty small you'll need at least an 8 gauge amp kit like this one from streetwires: http://www.crutchfield.com/cgi-bin/S-gnCTJ0gr4GW/ProdView.asp?s=0&c=11&g=711&I=211PS8RI&o=m&a=0&cc=01&avf=N Also since your subs are not dual voice coil you should wire them to the Rockford amp like this to get 2 ohms:
