I am not saying that go for 944 it is a class AB amp but the 510 is a class D
The 944 is good for mids and highs but not recommended for sub because it not so effiecnt and uses lots of power against class D so if u want an amp for sub go for class D only. One more Thing Class D does not mean Digital Amp It is class D amp. Any doubt about Class D search on the net for it.

Class AB amplifiers sounds good on subwoofers. But comparitively Class AB amplification for sub turns out to be expensive compared to Class D...but definitely sounds better...provided you use good quality subwoofers.

Also I set the LPF on the amp to middle of the freq knob and the gain to the middle and from the head unit LPF to 125hz so that all the freq goes to the amp without being filtered. and further adjusted the freq from the amp where it sounded right.

One more thing I earlier I had pioneer 944 (75x4 , 250x2)it might be not a such i good amp but i like it. I used to drive two 1241 pioneer woofer with them they sounded very good But with 510 i did not got satisfied. I bought the 510 amp and sold it in 10 days of purchase. Rest it is up to u which amp to buy It is your hard own money.


Autophile Sir what are the other options for an amp (other than alpine) for 20k for bass as i need some more amp for my other car
LBM there are not much settings on an amplifier than a gain, crossover and eq. And setting it up is 5 mins job. The bass is not only dependent on the amplifier itself. It depends on the subwoofer choice, enclosure quality, source and cables also.

Putting the sub in box and playing around with the amplifier is not the final line of getting base. There are lot of things.

The quipment choice is very subjective. That does not mean the other equipment is just trash. Definitely one can be better than other and often comes at an extra cost.

what u said is quite right I agreed with u 100% but u said for sound adjusment I have tryied every possible manner to adjust the sound but the 510 was underpowered to me or it could not meet my expectations. Tell me YAAR why woul i will spend 10.5k on a amp and sell it for 7.5k 10 days later.There might be some thing wrong. Also the wiring done at the time of 510 is same as that of now. No wire was changed between the two setups. One more thing I have tryied near 6 box enclosure (made from mdf and the side walls where seal from siliconeso no air leaks, also added sound absorbing material also) seal and ported from varies sizes starting from 1.1 , 1.25 , 1.65 different woofer placements face top , face backwards ,facing front. All these setting were measured at contant volume for all the setups with a db meter for freq starting 10 hz to 120 hz for sound output and several track where played for max db attained and the results where compared. so i dont think i just have said some thing about the amp is not correct. Lastly said it is your money spend it wisely.

Autophile Sir I am waiting for the option of amp other than alpine for 20k range for sub as my friend need and he is going to get in few days if u have any suggestion please tell me. I might be coming to driven on coming sunday for rca and power cables. I have made some changes and added your audison ports to the box and sound now coming is very good. I hope u will like it.

Also i have check the spread of the freq curve by plotting the db output of the freq given out by the sound system and i saw a fine nice most flat curve from my latest setting running in my car
