whats so wrong with the audiobahn amps the mtx amp is rated 350 rms at 2 ohms and the audiobahn is 1200 rms at 1 ohm wouldn't u thin the 2 audiobahns 1300hct will be louder than 2 mtx 4250d amps
I would keep the mtx if you want something reliable. Also why does your friend want to trade 2400 watts for 700-800 watts. The bahns probably will be louder but the mtx amps will take a beating. I have had the thunder 280, 420d, and currently 1000D. The 4250d were running two 15s( granted they were pyramid super blues) about 5 years ago in a hatch back. The 4250D also ran some orion xtrs and one e12k in a vt box. All in all I would keep the mtx amps or trade them for something else.
