I'm installing a "used/New" system in a 2000 Jeep GC with my son. Anyway, the HU is a MEX-BT3000(used) which only has 2 RCA outputs. one is going to a 4 channel BOSS CXX1204 amp(powers 2 3-way fosgate front speakers on channel 1/2...3/4 is not used) and the other is going to a (used)sony xplod amp (for 2 10" subs). System sounds good (for me anyway) but he wanted to get more highs and replaced the factory tweeters in the dash with a new pair of alpin 110 with crossover.
Anyway, since the HU only has 2 RCA outs I connected the tweeters to the same connections on the BOSS amp with the fosgate front speakers. The tweeters do work but you can barely hear them. I am by no means an audio guy, but without replacing any/all of his equipment. Is there a better way to run the new tweeters? I called the place where he purchased them but they want $$ to answer any ?
I hope someone can point me in the right direction.
