I hooked up the 7998 the other day, and now i have this wierd noise, sounds like interference. I didnt have it with the 8600mp.

RCA's are run down the side opposite from the power wire, so thats definitly not the problem. Maybe i should buy some better rca's, the ones going to the sub were higher end, but the two going to the 4 channel amp were generic.

It sounds like shit, but ive only messed with it for 5 minutes //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I'll mess with it a little more later on today.

Perhaps you could try re-grounding the 7998 direct to the battery. Alpines can be finicky about inducted noise with a bad ground.

Good idea //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

keep that 7998. if it was the 860 i might lean towards the 860 because it has more tuning capabilites but since its the 8600, hands down the 7998.

Hey I have the same one and love it.The fact it has the one set of RCA's for a sub and front and rear for highs has me confused lately.It's never been a issue to me till I joined here.My front and rears are going to my main amp for my highs and the ONE set for sub is going to one of my mono amps.the mono doesnt have a set of pre outs on it so I'm Y jacked to my second matching mono amp.Question is can I use the set of pre outs on my 4ch.main amp since it has the RCA's of the HU for the front and rears going to it for my other mono amp.

Cool I just wasn't sure.I always thought you couln't run a sub or sub amp off your front and rear rca outputs.Thats why they were designated that way.
