Hi there, i have read almost all the forum and no answer for this... my rear bose amp blew up so i bought an aftermarket clarion amp (1200 W), i connected the rear speakers and they sound OK, but i cant make front speakers work. I know wish output wires are but there is no sound at all, i can make the tweeters work but i cant make front speakers work. have anybody with an aftermarket amp been able to make bose front speakers to work?? if thats so please i need help, pictures or anything will help.

I dont get it. Are they in series ? I connected The right wires of the front speakers. But no sound.

Well it's fairly obvious that the front speakers aren't working because they are hooked up to the Bose amp - you'd have to take it apart and bypass that speaker's own amp.

And you won't like the sound you get if you do, Bose speakers are quite band-specific, and sound awful without their crossover.

i cant find bose front speakers amp. its that little thing on the top of the speaker??
i dont think everyone that install an aftermarket amp does this, isnt there another way?

Yes. I have read everypost regarding my case. First of all door relay problem was almost exclusively of series 1 rx8. Mine Is series 2. And they work perfectly with original bose amp so there Is no problem with relays. My problem Is with aftermarket amp, you didnt even read my problem or understand it before telling me to search.

Here are a few more diagrams for the system, keep in mind when an OEM system uses relay amps, the main amp might send a signal to the relay amp to turn on. Also, by the looks of it, they may only be sending a digital signal to the front amps, so you will have to troubleshoot by using a multimeter to follow the wires and ensure the connectivity is there.

The bose amp switches the door speakers on so to use an aftermarket amp, you would also need to add switched voltage to the turn on lead of the bose speaker. Best find out what voltage that is but is likely just 12v.


Bose uses an interesting trick to power the door speakers by using the single speaker output from the rear amp to also provide signal to the front door speaker amp. The equalisation curve added to the front output of the bose amp means lower frequencies are actually quite a few DB down so the input signal to the amp in the door speakers is barely 1v most of the time. Kind of clever but hard to get around. By this I mean if you try to drive the front speaker amps with a new non equalised amp, you will in fact give them WAY too much signal. They are also very small amps so there's not much benefit.


You CAN directly drive them by removing the amp(you have to drill the rivets etc) or alternatively use the Bose woofers from the S1(almost identical except for plug position AND the fact a S1 has a serperate amp.


People claim they ar 0.5ohm but they actually measure closer to 1 ohm. You COULD find amps to run them but after all of that you're better off just using a decent component set now that you have removed the Bose amp.


Oddly enough, the bose speakers when driven directly aren't all that bad(individually) but Bose equalises them to sound 'impressive' when you only listen for 5 minutes. It does get a little tiring after a while though.


Don't listen to the 'only paper' garbage people repeat constantly, some of the best speakers in the world are paper, ALMOST EVERY live sound speaker is paper and the ONLY reason NOT to use paper is moisture resistance. Many 'fancy' speaker cones measure WORSE than paper and are usually gimmicks to make you buy injection moulded plastic crap.


Someone call a company like Fostex or Scanspeak and tell them paper is no good. Be prepared to have your ignorance exposed haha.

Good answer, its been a lot of trouble, i think i will have to change front speakers... JBL speakers are cheaper than buying new bose rear amp. :/
