fixing up my system

ok i thought of another option if i were to gt this us acoustics amp USX1000D instead of getting another amp that i have and running 2 of the same amps to1 to each sub. if i do it this way with 1 amp to 2 subs like the way i had it but with this new amp is it outputting the same power and is it less current draw or am i bette just going with the 2 amps?????? heres the specs on the bigger mono amp thanks Amplifier Type: Mono RMS Power: 550W x 1 @ 4 ohms Bridged RMS Power: 750W x 1 @ 2 ohms THD at Rated RMS Power: < 0.5% Speaker Level Inputs: Yes Preamp Outputs: Yes Built-In Crossovers: LP Bass Boost: n/a Frequency Response: n/a Channel Separation: n/a Signal to Noise Ratio: > 80 dB Fuse Rating: 2 x 40 amps

I think that amp will be less of a draw than the 2 amps, and if you run a common chamber enclosure, running one amp is alot better... as far as building the amprack and everything, that sounds pretty cool, but dont build the sub box out of aluminum or coat it with aluminum either...make sure the sub box is mdf or fiberglass...aluminum will give some crazy resonance... I would also look at upgrading the subs as well...I personally dont find them very nice sounding and think you could do way better with a different sub as far as output is concerned as well... and I would also ditch the caps...both of them...they will do more harm than good...

i just got a my new magazine in the mail yesterday and i was looking at the new alipne 12 type r subs you think 1 of those with either my 1 amp or another amp will sound better and hit harder than what i have now what you guys think? if im gona change my whole system instead of useing my old stuff i want to buy something good so im open to suggestions please let me know

ok heres my final thought 1-Alpine SWR-1221D 12" subSize 12" Impedance 4 OHM + 4 OHM Power Handling 1000 WATTS /300 WATTS RMS Frequency Response Fs-1kHz Sensitivity 87db D.C.
