I'm going to pull my BMW Traffic Pro H/U from my Z3 and install it in my '91 318i. I also picked up a set of premium speakers to install as well.
- TP info here: http://www.waycoolinc.com/z3/01/081501/whatistp.html
My question is, will the amp in the TP have enough juice to provide adequate sound to the premium speakers or should I be looking for an amp?
Here are the specs for the TP:

SPECIFICATIONSWavebands:FM 87.9MHz – 107.9 MHz
AM 530kHz – 1700kHzFrequency range:20Hz – 20kHz for CD operations
30Hz – 15kHz for FM
50Hz – 2.5kHz for AMOutput:4 x 18 WattsLine cross section:0.75mm2 min.Loudspeaker impedance:min. 4 OhmsLine out:4 x analog line out (Va max 3Veff at 10k Ohms)GAL:Speed-dependent volume control; the adjustment is
performed in 8 to 19 steps of 1.25dB, dependent
on current setting.Antenna:Impedance 50 Ohms
AF Telephone Input:Max. input voltage 8V (if interference occurs, a
commercially available 1:1 transmitter should be
connected into the signal cable).AUX input:16k Ohms input impedance, max. input voltage 1.7VeffTelephone mute:Low active level < 2 VoltsSupply voltage:12 VoltsPlayable CDs:Playable CDs are standard CD audio format, CDRs and CDRWs. 3-1/2" discs are not playable.
