gally Posted September 24, 2011 Report Share Posted September 24, 2011 There in lies your problem. HPF will HPF all deck outputs(I believe). Therefore, when it is turned on, then it will affect your sub amp. Unless the set of RCAs you use is for Sub only. let say that he HAS 2 sets of preouts...one set for the front and one set for the rear speakers so the thing is...why not sacrificing the rear speakers for the sub(you surely wont need rear speakers)? in that case the HPF wont affect the sub but it will affect the sub because its still a TRUE rear channel so the headunit WILL apply hpf settings to it NO MATTER WHAT...... ive been here done that on alot of h/u and there is no way around it..... either turn your hpf off or dont run a sub..... lol my 2 cents realy? so how am i playin my sub perfectly with the 2 sets of preouts on my alpine?? 2010 Chevrolet Cruze Radio --- pioneer mvh-200vbt Front/back --- alpine type s 6.5" Sub Control --- Pac LC1 Sub Amp --- GZPA 1.4K Sub --- GZNW 15XSPL D1 Battery - GZBP 12.2500X Link to comment Share on other sites More sharing options...

THEN.....CHECK these it doesnt have a sub pre out... but you can sacrifice your rear speakers for the sub....and the HPF wont affect the subs it worked for me ++++it has 2 SETS of preouts ill gladly sacrifice my rears for my sub. so just use the other set of preouts? finally something worth trying. dont read!

Skullz Posted September 24, 2011 Report Share Posted September 24, 2011 Make sure your sub is connected to the rear channels and turn on the sub output, that should let you now control the sub volume. If you mistakenly connected the subs to the fronts you aren't getting any signal to them. 01 Ford focus ZX3 Pioneer AVH-X491BHS PPI PC 4800.2 Morel Maximo 6.5" x2 Link to comment Share on other sites More sharing options...

JEMT8 Posted September 24, 2011 Report Share Posted September 24, 2011 thanks god...finnaly there IS someone who knows l lil mor than the others It's not that. You just didnt convey your idea properly IMO. "you can sacrifice your rears for the subs" isn't the same as switching your preout mode from rear to sub. formerly known as Jaylor Swift Link to comment Share on other sites More sharing options...

sayhuh? Posted September 24, 2011 Report Share Posted September 24, 2011 Make sure your sub is connected to the rear channels and turn on the sub output, that should let you now control the sub volume. If you mistakenly connected the subs to the fronts you aren't getting any signal to them. Exactly. After looking at his deck specs, he can do this, which is what I was getting at and actually got at a few times. If his deck didn't have switchable RCAs, then HPF would still cause his problem. thanks god...finnaly there IS someone who knows l lil mor than the others I hope this is directed at me...

sayhuh? Posted September 24, 2011 Report Share Posted September 24, 2011 no success with trying different preouts any body else have any ideas, maybe new head unit? ugh.. You have to change your deck settings too. Change your rear preamps to Sub preamps. Blown Link to comment Share on other sites More sharing options...
