[quote name='cobaltitaliano']Looking for opinions on amp now. Heard there may be a better less costly amp for my setup besides the aq1200d. I found the following 2:
Kenwood KAC-9105D
1800W Max Class D Monoblock Performance Series Amplifier
(I know it is not 1800 watts, but it is 900 watts rms at 2 ohm)
Hifonics HFi1500D
1500W RMS Class D Monoblock HFi Series Amplifier (HFi 1500D
Heard both bad and good thins with this amp...100 watts rms at 2 ohm load
So between the kenwood, hifonics and aq1200d which is best for me? If you have other options please list them and tell me why thanks[/QUOTE]
FIRST, NO MATTER WHICH OF THE ABOVE AMPS YOU BUY, YOU WILL NEED A BIG 3 UPGRADE this is the most beneficial and efficient upgrade you will need to do. Most of the amp failures today are from fools buying amps just like you are looking at and dropping them to 1 ohm and driving the crap out of them on stock electrical wiring and a stock battery.
As a suggestion, I would look for the best deal on the best amp I could find, and just buy subs to match my build design like enclosure requirements, ported vs sealed, etc. If you wanted a good tight sounding and decently loud system, you would just need to purchase
quality built D4 subs wired to 4ohms in a custom box that can handle more power if needed,(600w/ea). 700 watts at 4 ohms with 85+% efficiency, you might not even need to upgrade your battery...might.
If you wanted really stupid loud, just wire them down to 1 ohm and run heavy wire to the back with an extra battery..(easily done)
in other words, take 2 these and wire them to 4ohms and bump til you can afford to run some heavy ga. to the back and upgrade your stock battery or add one in the back. Then wire them down to 1ohm and let er rip. You will not be disappointed with your purchases and you will have some of the best available equipment for the $.
Get with one of the guys who run these subs like
@Kangaroux to discuss these subs and what they can do and how they like to do it.

...the subs above would get 350 watts each on the following amp wired to 4ohms, or 800-1000 each wired to 1ohm and beefed electrical.

Personally, I care not what choices you make, I don't make a dime off your decisions,but I do not like to see anyone make an uninformed decision and regret it down the road...the system I suggest at 4ohms will sound better and outperform the above mentioned amps at 2 or 1 ohm. And be super efficient.
