I recently purchased and installed a midrange price CD tuner system for my car. 200 watts sent to front and rear speakers, a very good tuner, plenty of EQ settings, it sounds great. When I bought this 82900T4dr 8 months ago, It came with two Sony amplifiers (plus wiring sent to the dash) beneath the rear seat. I think they're 30 watts each. Could be 50 (bad eyes). I obviously have no use for them with my currect setup, but I'm thinking of installing a subwoofer in the trunk. I visited a retail electronics store last night to ask some q's, but the young guy wasn't much help. The CD/tuner/amp I have has two unused RCA connections on the rear that I understand are meant to be fed to an exterior amp. Considering that I want just one subwoofer, how do I rig this up? Three main questions:
1. Can I bridge those two RCA lines together into one without canceling the stereo on the other four channels?
2. Is there a way to utilyze both 30 watt amps either in parallel fashion to power the one subwoofer speaker? Perhaps - send the two seperate signals from the tuner amp into each 30 watt amp and then join them together at output?
3. I obviously need a frequency cut-off so as to not send unwanted frequencies to the woofer. Is there a simple cut-off circuit? On that issue I could use my unused SAAB/Clarion EQ to lower those frequencies and generally fine tune the sound before the signal is sent to the amps.
I could also just have two large speakers hooked up in the trunk powered by each 30 watt amp and fine tune the frequency range sent to them via the EQ. Sort of a cross-breed subwoofer system.
Thoughts anyone?
