I was wondering if someone could help me find an amp for two 15" Alpine type R dual 4 ohm subs. i am looking for a single amp, I do not want dual amps anymore, and I am also hoping it will be something that won't break the bank either. My budget is around $400 to $600. I might be able to go slightly higher if necessary. The subs handle 750 RMS each, so the amp needs to push out at least 1500 watts RMS at 1 or 4 ohm stable. Thanks in advance for the help!

you could go with the Kenwood KAC-9102D. it is a mono block amplifier that is rated at something like 1800 max and you could try running the woofers in 8 ohms each or 4 ohms each. this amp is 2 ohm stable so if you do each sub as a 4 ohm then you can maximize the amp and the subs. i really don't care for Kenwood as a whole but they make some really good amps. i also like the KAC-7202 or KAC-7252 (with the bass knob) but you will be limited to less power but you can manipulate the impedance a little more because it is a 2 channel amp that you can bridge and drop the ohm load. if you running 2 woofer and need more power i would probably go with the mono amp. good luck and hope this helps. btw, 9102D runs about $300 and the 7202 runs about $200. great time to buy since everyone is running sales to blow out the 2006 models for the same product with different model numbers (and higher price) of the 2007 model. good luck and hope this helps.

btw, don't scrimp on the amp kit. get a true 4 AWG kit for it or else. trust me... good luck.

He has dual 4 ohm subs...so something that is 1 ohm stable...the 9102D is a good amp..but only good enough for one Type R.
He asked for something that will push around 1500 watts...the 9102D will push nowhere near that...that 1800 watt number is only a PEAK number...which means pretty much nothing.

yea, if the subs are 4 ohm duals each then the 9102d is perfect for it. run each woofer in 4 ohm and mono them into the single channel on the mono amp. that will give a 2 ohm load at the amp and then tune the gain to the subs. i do agree that the max output on that amp is 1800 watts but it is also rated under the CEA so even though those numbers don't mean anything that amp will run those woofers all day long with no problems. of course it would be better to run one amp per woofer. if that is possible then get KAC-7252 or KAC-7202 (identical except for the remote bass knob) which are both 2 channel bridgeable amps. good luck and hope this helps.

The Rockford Fosgate T1001bd mono amp is the amp with the highest power rating that fits your price range, that I could find on the internet doing a quick search. You could pick up a Boss amp for $300 that is rated for 2000 watts at 1 ohm, but the quality isn't any where near what the Rockford or similar big brand amp would have (you get what you pay for).
If you live near any local shops, you should go out and look at what they have too. If you go in and spend some time talking with some sales people they could probably get you a pretty good price on an amp.

The KAC7252 is NOTHING like the KAC-9152D sir...the 9152D or the 9102D will only give each sub 450 watts rms while the 7252 will only give each sub 250 watts rms...which is nothing where the original poster is asking for. One 7252 or 7202 is only good enough to hardly push one sub

actually i have been running the kenwood amps (both mono and 2 channel) on multiple subs for years. i was saying that he could use 1 7202 on each sub or the 9102 on both. i am pretty sure that the 9102d will be enough to run those woofers but everyone is entitled to their opinion. i work with kenwood, fosgate, apline everyday and of course i have certain beliefs based on what i have seen for performance vs. price. anyway, good luck and hope this helps.

'bmwpwner', please stop posting uneducated advise...
First off, the only Kenwood mono amps that could run those subs are the KAC-9152d or the KAC-X812d. Being that they are both 1ohm stable. But, they still do not have enough power output to push those subs. They are CEA Compliant, but they are also rated around 900rms. That 1800w peak number is not a CEA compliant number. It is a marketing scheme to lure in uneducated buyers...
Secondly, two dual 4ohm subs cannot be wired to show the amp a 2ohm load. The only two possible impedance numbers you can get from two dual 4ohm drivers, would be 4ohms, or 1ohm. So in that light, 'roboutin2' will need to find either a powerful 2-Channel or a 1ohm stable mono block...
As aznboi stated before, the Sundown SAZ-1500 would be a perfect choice for your application, and they will run you about $450-$600...If you're looking for something a bit cheaper, I would check out maybe a Hifonics BXi-1606d. They usually run around $250-$300...
And 'bmwpwner', where exactly is it that you work, Best Buy im guessing? Just because you sell a product or work with it does not automatically make you an expert(obviously)...95% of what you have stated is completely wrong...But thankyou for the laugh, your signature is about the most ironic thing I have read all week...
