Keagan-Z06 Posted August 31, 2015 Report Share Posted August 31, 2015 Hi Everyone, Took me a while but I finally ran into SMD website since lately I've been upgrading my car audio for my 06 Avalanche. I don't have anything wild and probably will keep it this way until I can get the bigger bucks. I sure wish I had found this site before I went ahead and got what I have in now. Nevertheless I am content at the moment. I have a couple questions from browsing for the past 2 weeks on this site and watching all of Steve's tutorial and build videos. My build: HU: Pioneer AVH X4500BT (Will upgrade to NEX 4100) Subwoofers: 2 Rockford 10" R2SD4-10 Shallow 4ohm DVC Enclosure: Dual Sealed Amplifier: P500-1bd Wired: @ 1ohm using 4gauge wires (500RMS) Door Speakers: Rear: Polk Audio db651s Coaxial Front: Db6501 Components Amplifier: Pioneer GM A5602 Wired: @ 4ohms (150RMS) Like I said nothing too wild but a great improvement over factory. I already know for one after watching Steve do his thing, I want and NEED a DD-1, two) I want and NEED OM-1s. Lol Questions: 1) Since Im wired 1ohm using the above amp using the RF wiring guide for the above subs. Would I need 2 OM-1 to reflect 2 subs output or just 1. 2) When adjusting gain for mids & high, seeing that I have what I believe is a passive crossover, I tried doing this "by ear" and man do the tweets scream, don't even think I heard the mids, I don't even think the gain was even quarter of the way up before I had to back off. I know this wasn't the most efficient way of tuning but until I can get the DD-1, are the polks that loud that the gain would not even need to be adjusted that much even when using the DD-1? Sorry for the long first thread. Ill post pictures when I can.

reedal Posted August 31, 2015 Report Share Posted August 31, 2015 1) just one OM-1 since the subs will see the exact same output being it is a single monoblock amp powering them. 2) don't adjust your gain until you can do it properly. But also, there's sometimes an attenuator switch on the crossovers allowing you to attenuate the tweeters by -3dB or -6db SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
Keagan-Z06 Posted August 31, 2015 Author Report Share Posted August 31, 2015 Thanks man, I do have -3,0,+3 on the crossover for the polks. I'll mess with those when I get the DD-1. Hopefully will be ordering both today. Sick of my friend telling me he is better tuned. Although I'm assuming he does it by ear as well.

Keagan-Z06 Posted August 31, 2015 Author Report Share Posted August 31, 2015 Should of asked this earlier, the pioneer amp has a LPF, I normally have this off but when I do turn it on it seems to kill the components almost completely and leave the coaxials playing. Is this normal behavior or am I missing something? The Coaxials are not powered by the amp.

reedal Posted August 31, 2015 Report Share Posted August 31, 2015 Leave the LPF off or all the way maxed out, the crossovers will do the filtering for you SMD Tool Map https://www.stevemeadedesigns.com/board/topic/193176-smd-tool-map-new-november-2014/ Build log https://www.stevemeadedesigns.com/board/topic/197217-reeds-03-tahoe-hat-sqaq-singer-xs-shca-cockbox-80prs/?page=32 Link to comment Share on other sites More sharing options...
