my bro has a cheap HU lying around (PIONEER DEH-P33) that only has 1 pair of RCA outputs. im thinkin of puttin that in while i save money for my deck. my problem is im going to run a 2ch and a 4ch amp. with only 1 set of outputs i was thinking i could use Y-adapters and split it, making 2 outputs for the 4ch amp...while i use a line output converter for the 2ch amp. the only hesitation i have is that i dont know how good the sound quality is.

anyone know if the quality of this setup will sound "average"?
is the split with the Y-adapters in any way going to put two much of a load on the deck or anything else?
or will it not have the same amount of power coming out of it?
multi-amp...where should i wire BOTH remotes? i read that wiring more than 1 to the HU will risk burning out the turn-on or power antenna circuit. but it says connecting a relay will solve the problem. how much is a relay and how easy to install (any wires)?
or should i just put 1 remote on HU and 1 on the cig?

still a newbie wen it comes to DIYing and alot of other stuff...THANKS IN ADVANCE FOR ALL HELP!!! [IMG]i/expressions/beer_yum.gif[/IMG][IMG]i/expressions/beer_yum.gif[/IMG]

Using Y adapters is plenty okay..you can wire 2 amps to 1 remote wire without any worries....Do not use a line output converter..using 2 sets of Y adapters will still give you better sound quality.

with that answered, is this wiring ok?

if i have 1 set of RCAs going to the trunk and input of the 2ch, then have the Y-adapters coming out of the 2ch and run RCAs from that onto the 4ch?

that way i will have less wire hiding to do, instead of attaching the adapters to the HU, then route 3 SETS OF RCAs to the trunk!!!
i wont even know if thats possible, will the door sill even hold that many wires?!?!

THANX AGAIN!!!

run the single RCA to the trunk..then use the splitters from there..

oh, the sill will hold that many wires... im a testament to that one

drivers side : 3 sets of big ol stinger rca's, 2 sets of 12 gauge monster speaker wire...

passenger side, 4 gauge power, 2 remote wires, 2 other 12 volt lines....

and i still got room... soon theres gonna be another 4 gauge back there

The sills will yeah..but it's a helluva lot more cost effective to just run 1..then split.. 3 16 foot RCA's..vs.. 1 16 footer and 2 Y Adapters.. hmmmm... [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

But yeah..there's room for 1/0 Guage under the sill..

sorry its still not really clear to me yet
should i run 1 set to the trunk then split to both amps....or run 1 set into the 2ch then hook up the Y on the output of the 2ch.
the 1st way i will have to buy 4 Y's and 4 RCAs...but the 2nd setup i will only need 2 Y's and 3 RCAs
the only uncertainty i have about the 2nd setup is that i dont know if the 2ch OUTPUT can handle the split for the 4ch

also...since u mentioned 1/0 guage...whats so special about it, cuz it costs alot!!! pic?
