dr hypothesis Posted March 18, 2009 Report Share Posted March 18, 2009 Was debating to post this question yet, since my car is in the shop getting repaired. I hit a deer on the way to try and finish my install: Won't get my car back tell the 24th. Anyways, here's whats in the car: Two BTL 18s, walled up. 14 cubes, 35hz tune, 192" of port. There is also a d3400 under the hood with a 200 amp Iraggi alt. Two runs + front to back and one run of -. Big 3 done as well. All KnuKonceptz wiring. HU is an Eclipse 8053. I was able to play around (listen, aka SLAMMIN) with my system for a couple days before I took it in to get repaired. I pretty much finished it the day after the accident. The problem is when listening at loud volumes, the bass will get lower then higher. Doesn't happen all the time, it's kind of random it seems like. Some songs it won't happen at all. I've done a search on every forum I know of and only found a few threads from people with the same problem. Didn't find any answers. Only thing I can think of is it's the Memphis 4kw. I put this amp through absolute hell with my last setup, and it saw low voltage quite often. Not enough to actually smoke the amp. It did shut off from low voltage/heat quite often though. I'm thinking maybe I damaged the amp at some point? I've had nothing but trouble trying to run 4kw+ daily. I hate posting this question without even having my vehicle right now, but this is eating at my brain and I know I'm gonna overthink the shit out of this problem. Just looking for any type of input or info. My wall is not fully sealed yet either, still a trim panel on the port side missing. Doesn't seem like it's cancellation though.

dr hypothesis Posted March 18, 2009 Author Report Share Posted March 18, 2009 that's extensive work. I guess go big or go home! Wasn't too much work, even by myself. One day I might try to make an install that looks good though. All I really want these days is :hairtrick: Quote 2001 Chevy Impala Eclipse CD7200 mkii Cactus Sounds 5kw Sundown 100.4 (2) Fi BTL 18s (walled) ID 6.5s (2 sets) Iraggi 320 amp Alt XS Power Batts KnuKonceptz Wiring MidwestSPL Scores: 152.0 Advanced 2 136.1 Extreme 3 Link to comment Share on other sites More sharing options...
Sampsonite Posted March 18, 2009 Report Share Posted March 18, 2009 (edited) generally hit higher #'s with the port on the other side Edited March 18, 2009 by footlongsam Quote --Sampson 816-591-6592 www.kcrimshop.com Link to comment Share on other sites More sharing options...
Sampsonite Posted March 18, 2009 Report Share Posted March 18, 2009 I think Bass4Lyfe is having the exact same problem with his t4000bd right now too. Quote --Sampson 816-591-6592 www.kcrimshop.com Link to comment Share on other sites More sharing options...
dr hypothesis Posted March 18, 2009 Author Report Share Posted March 18, 2009 generally hit higher #'s with the port on the other side Yes, I know. I don't compete. We don't have comps in North Dakota or anywhere even close. I've had a couple different walls the past few years, thought I'd try the port on the passenger side for once. This thing does hurt my ears, which hasn't happened in a long time.

uhoh_45 Posted March 18, 2009 Report Share Posted March 18, 2009 just throwing this out there those amps are power hungry and you might need to upgrade your alt if you haven't already and possibly add another battery Quote R.I.P!

Beanz Posted March 18, 2009 Report Share Posted March 18, 2009 i kind of have the same problem also just that i installed my "new stereo"and all of a sudden it stats doin that also.i would like to figure this out also. Quote That's why they don't deliver. Yer ass better go sit along the side of the road and wait. You can't expect them to travel up some dirt road in a hick / back woods town. Thats how horror movies start I explain things very simply and use analogies in terms of Pickles, and grape drink, pool noodles and jackhammers...if you can't put 2 and 2 together there man, There simply is not much more I can do.

dr hypothesis Posted March 18, 2009 Author Report Share Posted March 18, 2009 (edited) just throwing this out there those amps are power hungry and you might need to upgrade your alt if you haven't already and possibly add another battery Yeah I know they are. I thought the 200 amp alt, PM d3400 and d3100 would be good enough for daily. I do like to slam on it though. Gotta wait tell I get my car back to be able to check out the voltage when it's turned up. Didn't have this problem previously with the Memphis running off of g34 Yellow Tops. The amp would just end up getting hot and shutting off. Haven't gotten to that point with the new electrical. Even the first song I listen to after starting my car will do this, voltage should be pretty good at that point, but I'm no expert. Also, the amp isn't cutting out. The volume of the bass only fluctuates randomly, it'll get softer then louder, happens for a couple seconds. It's not constantly happening throughtout a song either, maybe a few times.

Boon Posted March 18, 2009 Report Share Posted March 18, 2009 (edited) Amp might be a bit sick, but check the voltage across the power terminals while you're bumping and see if it's dropping badly for some reason. Also try a tone and see if it does it on that, if not it's possible your box just has a terrible frequency response that is all over the place... EDIT: How long is your port? Edited March 18, 2009 by Boon Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
