Thanks for the information everyone. I have always used heavy cable when wiring up car audio equipment but have never used a stiffening capacitor. Will try some stiffening caps the next time. Hmmm was thinking of running the the tweets and midrange off the Xti, haven't decided if I was going to run ...

Glad to hear that Phoenix Gold has a good repair service.

That much difference between the xs and Ti. Never had the Ti hooked up because a change of plans.

Thanks for the information.

Good Day Everyone Looking to upgrade my XS2300 amplifiers. Have no problem in upgrading power supply caps and was wondering about other upgrades such as signal path caps and op amps. It would sure be nice to have schematics, all Phoenix Gold is preventing is DIY people from making repairs or upgrade...
