Well was just wondering is it good to run 2 type r subs running about 800 rms on stock batt and alt and what not no cap too also is Lanzar OPTI1400D a decent amp i can get 2 type r's box and that amp for 250

 

Need a model number of the type R subs.

Alpine Type R subs are 500W continuous, [RMS] so to drive them to their full potential you need a 1000W RMS amp into 2 or 4, [or 8] ohms, depending on the impedance of the Type Rs you have, DVC 2 ohm or DVC 4 ohm.

The Lanszar amp will do the job, at 1 ohm, [1x1311W RMS] would still sound OK at 2 ohms, [1x844W RMS] although underpowered by 150W, SQ would be better at 2 ohms, even with the lower power.

At a 4 ohm load you would be taking a risk of burning the subs VCs, [1x484W RMS] by constantly over-driving the amp.

If it is all working OK, $250 is fair, but the subs, box and amp must be in good working order and in good physical/cosmetic shape.

Rule of thumb is @ 500W RMS and above, upgrading the alt. is a good idea, it takes about 75A to produce 500W RMS, [about 125A to make 800W RMS] as you can see, even at 500W RMS you would be overloading your alt. 94

 

You should be fine running stock electrical on 800 R.m.S not (watts) By reducing the lights on your vehicle will provide power for you amp.

 

this is of course with atleast the big 3 being done, and maybe considering a upgraded battery. if not another new reliable stock replacement, a BIGGER battery. my car comes with a group 51. but i stuffed a group 34. doubled my CCA, and my AH burn.
