rewireing the whole car re-routing the RCA's in a different spot going to see if that does anything after that sending amp to rockford fosgate ... really think it is the amp

ok so as of right now i think the amp is broke .... i refixed the ground and it still makes the noise ... also what i noticed is that i have my front speakers hooked to front 2 channels and subwoofers hooked up to rear channels ... i put the front RCA into the front RCA jack and i get music coming from the front channels AND the subwoofers .... not subtle but like the subwoofer RCA's are hooked up and there NOT .... what is wrong with that picture ???!?!!!!?!?!?!??!

ok i will let you know how it goes tomorrow !! then i can actually start building the new box :-)

^^^^^^^^^^^^^^ yup on the expanding foam

yeah even when one of the 2 RCA is plugged into the REAR channel engine noise comes from both front speakers

i know but thank you for the help hopefully this will work >.< the noise is driving me crazy i cant even listen to music radio is off

i bought it when Best buy was switching over from rockford to kicker (MEH) and it was there display one was never plugged in just bolted to the rack to show people. got it for 130 so IF it is bad then i wont feel bad putting a few bucks in it because websited MSRP is 360. I will bolt it up to my rear strut mount i also think it could be the connection on terminals, it was my first ever solder job so maybe thats bad does anyone have like 7 or 8" of 0 gauge laying around :-)))

As of right now its grounded to seat belt bolt

I have a strong feeling it is the battery to chassis ground what would be best place in trunk to ground it to and a good terminal to use

Bump

If the batter ground is bad that could also cause my alt not putting out 14 volts also right ??

i just redid all my grounds all crimped connects all solid grounds ... i will recheck my battery ground ... what about the amp cutting out ? same thing ground problem ?

i have a p400-4 amp rear is running bridged at 2 ohm 200WRMS 2 p1 150WRMS each and front running 2 components, on the subs i have gain set at 3/4, punch set to about 1/4 running a 50hz tone sounded good no distortion sounded nice and clean. While playing a song when a heavy bass line starts up the amp will shut off and back on really quick. Also i have engine noise coming from the front tweeters. the noise is through the speakers also when engine is off i have constant high pitch whine. come in when 1 RCA gets plugged in in any of the 4 inputs, one rear is plugged in noise from front. i have my capacitor grounded on the battery terminal about 12" long. the amp is grounded to the capacitor about 4" long. running 4ga Rockford fosgate wire power and ground. Power from Batt to Cap is about 12-14" long power from amp to capacitor is 4" long. The RCA's are Rockford Fosgate single twist but i don't think it is coming from the RCA's due to i can plug in the sub RCA into the Rear and noise comes in to the front. I bought the amp from best buy and it was open box so i think it might be the amp i have tried all the other possibilities. RCA's are ran away from power wires and no part of RCA is coiled in a bundle. Any advice would be very helpful.

read the rules and no ebay linking either. http://www.stevemeadedesigns.com/board/topic/36708-garage-sale-forum-rules/

dont got much but looking for a good p300-1 used or new but good price

neither of i from wat i am gathering they are p1s made by rockford for gm the voice coil read on my dmm 1ohm double checked with another speaker that was 3 ohms read 3 ohms so it was not a faulty dmm

http://www.caraudiocraze.com/amplifiers/mono/cadence-xa-300-1-600w-mono-amplifier/prod_1068.html so the subwoofers are 150WRMS 300 PEAK is this a good amp ?? the subs are both 1ohm SVC can these be wired to 2 OHMS ???

eh well for now it sounds good .... can play it for about 10 min at max until it cuts out from heat :-( even with 4 fans and it lifted so the air flows on the vents below :-( lol 30 dollars you get what you pay for i hope it sounds alot better with a good rockford fosgate 400 mono amp ... still dont know what is up with the subs still ... rockford fosgate says there p1 come in 4 and 8 ohm SVC ebay says 2ohm SVC and dmm reads 1ohm voice coil ... WHAT SUBWOOFERS ARE THESE !!!!! and i double checked the dmm with a 3ohm speaker and it reads 3 ohms .... >.<

yup i got it for 30 bucks and its only a replacement until i can afford a nice mono amp but will prolly also find some nice 10" subs that sound good in a .58cu/ft per chamber box because the subs i have now are some kind of rockford fosgate sub no motor cover so i have no idea what the specs are

its a lanzar amp

i dont know how to tell if the amp puts out what it sais i wana say no because its a cheapo lanzar amp and i just hooked my subs up to a multimeter and the thing reads 1ohm .... i have a old rockford p1 i didnt think they made them 1ohm svc ...

i have an amp that is 400x2 at 4ohms 800x1 at 2 ohms could i just wire the 2 150WRMS 2ohm vc subs to run at 4ohms on one channel ?

thank you for the encouragement :-) its always the technical stuff that gets at me :-( jsut trying to learn how to do things the correct way starting with my own car to find out what ohm the VC is and then try to find the correct rated amp for them and be able to set it correctly ... the speakers i got didnt have a motor cover on them so there is no writing to tell me anything all i knwo is that its a rockford fosgate p1 150WRMS 300PEAK dont knwo the VC tho

i am good at installing and hooking things up i lack the technical skills and trouble shooting skills right now i have just started to learn this stuff for about a week now. i have built multiple boxes installed multiple HU installed speakers for friends who already had the equipments, i just lack the technical stuff ... still trying to learn it.

where do i put the little probe things, on the vc ?
