Question for audio experts here...

[Terrorize]

Hey everyone...just got a question...not too familiar with car audio...
so wanted to see if i installed this it would make a difference or not...

I was told by my installer that the amp on my deck is sufficient enough to power my speakers..however...with the air con on and road noise i find that my music isn't loud or clear enough...

Of course the people here in Canada...Futureshop and Bestbuy..all recommend and amp installed..but they have motives....so i want an honest answer if possible...

I don't want a Sub...because it would take up way too much of my limited trunk space..

This is what i have currently...

Pioneer DEH-P6800MP Head Unit - http://www.pioneerelectronics.com/pn...tailsComponent
Sony Xplod XS-V1640H 6-1/2" - Front Speakers
Sony Xplod XSV6930A 6" x 9" - Rear Speakers

I have seen 2 choices so far...and leaning towards the MTX...is this company/amp good? Thanks!
