upgrading subwoofers and amp

[johnny40]

HI all I am currently running alpine type r speakers throughout the car with the older type r subwoofers 500wrms each 2x 12inch ported box. Amps are a pdx 4 and a pdx m12 and even thou the subs sound ok at higher volume the front is just overpowering them. So i was looking at upgrading to the newer type r subs at 1000wrms each and adding another pdx m12 one amp per sub. the guy at the shop said around 3-4 db louder. Im pretty new to car audio atm but def need bass louder. Would the 3-4 db be actually helping me out thanks

Upgrading to that kind of power is going to snowball into a big chunk of money. Need big 3 (should already have this done honestly) high output alternator and at least one good agm battery. Otherwise you will be killing you electrical system and along with that your amps. If it was me I would grab a pair of FI SSD's over the alpine any day of the week. Someone else is going to have to help on the potential gains of your planed upgrade though.

3db louder would be twice as loud.

ok ty twice should be better

in theory it would be 3db louder. Be prepared for reality to be a little more disappointing though. So many variables that you seem to be ignoring.

I wouldn't recommend newer type R's if your current ones are not enough. It could also be something to deal with your box. Boxes can make a huge difference.

If you want something loud in the same price range as the Type R's, i'd look into something like, SoundQubed HDS300 series, American Bass XFL's or XR's, SSA GCON's, Sundown Audio SA series, Fi X series, and DC Audio level 2's are just a few i'd look into. Personally I switched from Type R's over to HDS312's and it was a huge difference.

I would also look into a different amplifier for more power... something like a Twisted Sounds 2.8K.
