Hello. I was thinking about putting Diamond Hex S500 speakers into my SC400. Anyone have any experience with these or know what the quality is? Will it definitely sound better than the stock Pioneer speakers? I have a Kenwood HU and Alpine MRP-F450 amp currently running stock speakers. Thanks.

Hello. I have a 1994 SC400 which came with the pioneer stereo. I just replaced my head unit with a Kenwood KDC-MP4032 and added an Alpine MRP-F450 amp to power the 6 main speakers (the stock subwoofer is getting power from the stock amp only). I've got it set as 2 channels up front and 2 channels in the back (1 for each woofer). I have 2 questions that I was hoping someone could help with: 1) What are the crossover frequency points for the stock pioneer speakers (tweeter/mid range up front and woofers out back)? Should I be setting HIGH-PASS for the front and LOW-PASS for the woofers in the back or leave them full range? What should the crossovers be given the stock pioneer speakers in the Lexus? I don't know what the frequency response of those stock pioneer speakers are. 2) The Kenwood stereo has 4V pre-outs. How much minimum gain should I set the Alpine amp to? Any light that can be shed on these questions would be greatly appreciated. I'm getting decent sound out of my stock speakers but not as good as before I got rid of the original head unit/amp. THANKS!

Hello. I am new to this forum. I have a 1994 SC400 with the stock Pioneer system with 6 speakers and subwoofer. I recently had a local shop (Zippos in NJ) replace my head unit with a Kenwood-MP4032 system. They tried to wire it to the stock amp but I was getting bad distortion (ground problem?) so they bypassed the amp and went directly to the speakers and are running the old subwoofer of the old stock amp. The sound is worse than it was before I got the new system installed - but I got it done so I could connect my ipod. They are suggesting I replace the entire remaining system (new amp and speakers). Do I have to get rid of the old speakers? Could I just add a new amp? Does anyone have any guidance about this? I used to like the old speakers but now they don't sound as good with the new head unit (maybe because there is no amp). I've also read on the board that people get rid of the old subwoofer. Is this something I need to do just because I have a new head unit? Feel free to email me at tejphatak@gmail.com if you can help me out. Thanks a lot!

Can you please post details on how to do this or email me at tejphatak@gmail.com? I have a 1994 sc400 with a Pioneer stereo with CD changer. I've been trying to figure out a way to hook up my ipod. Thanks!
