I recently upgraded my system and gave away my old p2002 RF amp and 10" alpine subs to my neighbor. They worked great in my car. In his it is hardly getting any power to the 10" subs at all. The subs are good (I just pulled them out of my car) but sound is extremely weak in his car. Only thing I can think of is either his head unit has issues or the rca's are bad. I checked and ground and power supplies are good. Would appreciate any help. As I said system was in my car (1 week ago) and sounded great.

What gauge wire are you running from the battery to run your Alpine amp? If the amp isn't able to draw enough current to drive your subs, it will not function properly. It could possibly damage your gear. Also check that your battery and alternator are up to the task. Car audio will load up the charging system in a vehicle if it's low powered. You may need to upgrade your alternator and battery.
get the alpine ktp445 mini amp ,it should be compatible (check your manual for your HU it will say ) its a plug and play install and you will hear a great improvement as I did and still got mine with the alpine cda 117 .
sub spec 250watts per coil you should be just fine I have 2 typr 15s on orion hcca 2500 1 and it kicks a$$ thats 1000 watts over the rated limits of the subs only shut the amp down once these subs can take a lot more power than they say just use your common sence with the volume and gain levels
Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg
Deffinitely but wired directly would be pointless, the Alpine's internal amp is way to weak to get the best out of the sub. You need an amp, minimum 300w and bridge the outputs to give all the power to sub preferably switched to low-pass (most amps will have a high / low pass switch)
The Alpine PDX-1.1000 is a physically small amp to produce the power that it does. The result is that it has less physical area for heat to dissipate. Running at or near it's maximum output into a 2 ohm load, it needs some serious airflow to keep it cooled down. I'd look for some way to get more air to it.
mostly because the subs in the back are probley using more amps than the ones in the front in the front should be used mostly for vocals and your bass in the trun so maybe trying to unhook the ones in the front from the sub and just leave then hooked up to the cd player where you can hear the vocals really good and leave your subs in the back hooked up to the amp
system not configurate properly go to a pro and let them do for you you have good equipment just need to put together rite.for wht you have you can get better sound than that,,good luck
