no do not use pre amp, they only bring in noise into the system. get a good HU that has inbuilt equilisers. ys its possible to get tuning from just the HU, if it has in built EQ and crossover. on the amp side not much.
oh ok,
hu with 3 band eq & with sub control features(2 pairs pre-out) enuf ar sifu?
or we need at least 3 pairs pre-out with 5 or 7 bands eq?
alpine cda 9835 (used), is it good? or better get new 9887?



) so much cheaper compared to malaysia...btw, why get the p80rs2? dun find it worth the diff compared to p80rs
Much better than the P80.
