Hi everyone so glad to have found you! I am very much into my music and have a very nice home system. Just bought a 2004 Lexus GS 300 that has the crappiest sounding system I have ever heard so I have purchased all new components for it. I went with an Alpine CDE- 175BT H.U,, an old school A/D/S PQ 10 4 channel amp, a set of A/D/S 300is panel speakers for the rear deck and a pair of JBL GTO 629 6.5 in speakers for the front doors. Nothing has been installed yet and I am hoping and praying everything I have will go well together. I wanted to run the specs by you to see if any problems catch your eye. The amp specs are 35x4 @4ohms, [email protected], [email protected] A/D/S 300is speakers are 4ohm rated 50 watts nominal 100 watts max, amp power 5 watts min 100 watts max. JBL GTO 629 speakers are 3 ohm rated, 225 watt peak power handling 75 watt RMS recommended amp power 5 watts- 200. I do notice one potential problem that being one set of speakers is 4 ohm rated and the other 3 ohm from the info provided do you think this system will work well together? Thank you so much for your help!
